- Ama-HDD ahlala enganqobeki ngomthamo nge-euro ngayinye, alungele ukugcina izinto eziningi kanye nokugcina ama-backups.
- Inketho engcono kakhulu ngokuvamile ukuhlanganisa i-SSD yesistimu nezinhlelo ne-HDD yedatha enkulu.
- Kungakhathaliseki ukuthi iyiphi indlela yokugcina ekhethiwe, ukuthembeka kwangempela kuncike ekugcineni ama-backups amaningana asesikhathini.
Ukukhetha phakathi kwe -SSD ne-HDD akuseyona nje isinqumo sochwepheshe bezobuchwepheshe: kuthinta ukuthi ikhompyutha yakho iqala ngokushesha kangakanani, ukuthi kuthatha isikhathi esingakanani ukuvula umdlalo, nokuthi unesikhala esingakanani sezithombe, amavidiyo, kanye nama-backup. Kulezi zinsuku, cishe yonke ikhompyutha entsha iza ne-SSD, kodwa ama-hard drive enziwe ngomshini asaphila kakhulu, ikakhulukazi uma kukhulunywa ngesitoreji esikhulu kanye nama-backup.
Kule migqa elandelayo, sizohlola wonke umehluko obalulekile phakathi kwama-SSD nama-HDD : indlela asebenza ngayo ngaphakathi, isivinini sawo sangempela, umthamo, ukusetshenziswa kwamandla, umsindo, ukuqina, isikhathi sokuphila, intengo, nokuthi iyiphi efaneleka kakhulu ezidingweni zakho. Umgomo uwukuthi uqedele lesi sihloko ngokuqonda okucacile kokuthi yiluphi uhlobo lwedrayivu okufanele ukhethe i-PC yakho, i-laptop, noma isitoreji sangaphandle , ngaphandle kolimi lobuchwepheshe olungadingekile kodwa futhi ngaphandle kokugxila ezintweni eziyisisekelo. Uma unemibuzo mayelana nezinketho eziphathwayo, hlola umhlahlandlela wethu wesitoreji sangaphandle.
Iyini i-HDD futhi isebenza kanjani ngempela?
I -HDD (i-Hard Disk Drive) iyi-hard drive yendabuko, idivayisi yokugcina idatha egcina idatha yakho ngisho noma ucima ikhompyutha yakho ngenxa yememori yayo engaguquki . Bezisetshenziswa kusukela ngawo-50 (i-IBM yayingowokuqala ukuzithengisa ngo-1956), futhi amandla azo akhuphukile futhi intengo yazo yehlile phakathi namashumi eminyaka.
Ngaphakathi, i-HDD iqukethe idiski eyodwa noma ngaphezulu eziqinile (amapuleti) ajikeleza ngesivinini esikhulu ngaphakathi kwebhokisi lensimbi. Ikhanda lokufunda/ukubhala lihamba phezu kwendawo ngayinye yalezi zipuleti ukuze lifunde noma libhale idatha kusetshenziswa i-magnetism, inqubo efana kakhulu neyesidlali serekhodi kodwa esikalini esincane kakhulu futhi ngokujikeleza okuphezulu kakhulu ngomzuzu.
Ijubane lala ma-plate liyisihluthulelo: uma ukujikeleza ngomzuzu (RPM) kuphakeme , isivinini sokufunda nokubhala singcono kakhulu. Kumakhompyutha asekhaya, ama-drive angu-5400 RPM noma angu-7200 RPM avamile , yize ezindaweni zobungcweti kanye namaseva, amamodeli afinyelela ku -10.000 ngisho naku-15.000 RPM . Noma kunjalo, asekude kakhulu nesivinini se-SSD yesimanje.
Ngokuphathelene nosayizi ongokoqobo, ama-HDD akhiqizwa ngokuyinhloko ngezindlela zokwakheka ezingama-2,5" kanye nama-3,5" . Ama-drive angu-3,5" ajwayelekile kumakhompyutha edeskithophu futhi anikeza umthamo ophezulu; ama-drive angu-2,5" avame kakhulu kuma-laptops nama-drive angaphandle. Okukhanga kakhulu ukuthi anikeza ama-terabytes amaningi esitoreji ngentengo ephansi , okwenza kube inketho ekhangayo kakhulu yokugcina idatha eningi. Ukuze uqonde kangcono izici zokwakheka kanye nebhodi lomama, bheka umhlahlandlela wethu wehadiwe yokugcina ngosayizi kanye nezici zokwakheka.
Amandla ajwayelekile e-hard drive yesimanje asukela ku -1 TB kuya ku-10 TB emakethe yabathengi, kanye namamodeli amakhulu atholakalayo ukuze asetshenziswe ngobungcweti. Ngenxa yomlando wawo omude kanye nokwenza ngcono kwezimboni, izindleko nge-gigabyte ngayinye ye-hard drive yomshini ziphansi kakhulu, okuye kwawavumela ukuthi ahlale eyisisekelo sesitoreji esingabizi kakhulu.
Iyini i-SSD futhi yini eyenza ihluke kwi-HDD?
I- Solid State Drive (SSD) iyi-solid-state drive ephinde igcine idatha unomphela, kodwa isebenza ngendlela ehluke ngokuphelele: esikhundleni sokujikelezisa ama-plate nama-head okufunda/ukubhala, isebenzisa ama-flash memory chip axhunywe ku-integrated circuit . Azikho izingxenye ezihambayo; konke ku-electronic.
Lawa ma-chip ngokuvamile ayi-NAND flash memory engashintshi , ekwazi ukugcina ulwazi ngisho nalapho iyunithi ilahlekelwa amandla. Idatha igcinwa kumaseli aqoqwe ngamabhulokhi; ukufinyelela kolwazi kuphathwa yiprosesa yangaphakathi ebizwa ngokuthi isilawuli , esinquma ukuthi idatha ngayinye ibhalwa kuphi, ukuthi itholakala kanjani, ukuthi i-cache ihlelwe kanjani, nokuthi amabhulokhi angasetshenziswanga asulwa kanjani.
Isilawuli kanye nememori ye-flash ye-NAND zifakwe ebhodini lesifunda eliphrintiwe (i-PCB) , elivame ukuhambisana nama-chip ememori ye-DRAM asebenza njenge-cache ukuze kusheshiswe ukufinyelela. Ngokungafani ne-HDD, i-SSD ingafunda futhi ibhale idatha kunoma yiliphi iseli cishe ngokushesha , ngaphandle kokuhambisa ikhanda lokufunda/lokubhala endaweni efanele, okunciphisa kakhulu izikhathi zokufinyelela.
Isici esiyingqayizivele sememori ye-flash ukuthi amabhlogo kumele asulwe ngokuphelele futhi abhalwe kabusha . Ibhloko ngalinye lingamelana nenani elilinganiselwe lemijikelezo yokubhala nokusula ngaphambi kokuba yonakale, futhi yilapho ukulinganisa ukuguguleka kuqala khona ukusebenza —indlela yokulawula esabalalisa ukubhala kuwo wonke amaseli atholakalayo ukuze kwandiswe isikhathi sokuphila kwe-SSD.
Enye intuthuko ebalulekile yi -3D NAND , lapho amaseli ebekwa khona ngezendlalelo eziningi ngaphakathi kwe-chip ukuze kwandiswe umthamo endaweni efanayo ebonakalayo. Ezingeni lohlobo lweseli, sithola i-SLC, i-MLC, i-TLC, ne-QLC, ezigcina kusukela ku-1 kuya ku-4 bits ngeseli ngalinye : lapho ama-bits amaningi, inkumbulo iba shibhile futhi inzima, kodwa futhi nokumelana kwayo nokubhala okunamandla kwehla.
Izici nezinhlobo zefomu le-SSD: i-SATA, i-M.2, ne-NVMe
Ama-SSD awafani nje kuphela ngohlobo lwememori ayisebenzisayo, kodwa futhi nasesimweni sawo somzimba kanye nesixhumi esibonakalayo sokuxhumana . Lokhu kubalulekile ngoba kunquma isivinini esiphezulu kanye nokuhambisana nebhodi lakho lomama noma i-laptop.
Ngakolunye uhlangothi, kune -SSD engu-2,5″ ene-interface ye-SATA , enesimo esifanayo somzimba njenge-HDD ze-laptop. Ziyindlela enhle kakhulu yokunikeza impilo yesibili kwi-PC noma i-laptop endala ngoba ngokuvamile zihambisana ngokugcwele: zixhuma echwebeni elifanayo futhi zisebenzisa indawo efanayo yokufaka, yize ijubane lazo linqunyelwe yi-SATA standard uqobo (cishe isivinini sangempela esingu-550-600 MB/s).
Ngakolunye uhlangothi, sinama -M.2 SSD , amabhodi amancane kakhulu futhi amancane, afana nebha, afakwe ngqo kubhodi lomama. Kunezinhlobo ezimbili eziyinhloko: i-M.2 SATA , ngaphakathi esasebenzisa iphrothokholi ye-SATA naphezu kokuba incane kakhulu, kanye ne-M.2 NVMe , esebenzisa izindlela ze-PCIe kanye nephrothokholi ye-NVMe ukwandisa isivinini kakhulu.
Ama-SSD e-M.2 NVMe angafinyelela isivinini esicishe sibe ngu-3.000-3.500 MB/s nge -PCIe 3.0 futhi adlule ku-7.000 MB/s nge -PCIe 4.0 , kuyilapho ama-drive okuqala e-PCIe 5.0 esevele efinyelela cishe ku- 10.000 MB/s kumamodeli aphezulu. Lokho kushesha kaningi kune-HDD futhi kushesha kaningana kune-SATA SSD yendabuko.
I-M.2 form factor iza ngobude nobubanzi obuhlukahlukene (izinhlobo 2242, 2260, 2280, njll.), kanti i-2280 iyona evame kakhulu kuma-PC nama-laptop anamuhla. Kunconywa ukuhlola imininingwane yebhodi lomama noma i-laptop ukuqinisekisa ukuthi yiziphi izici zefomu kanye nezinguqulo ze-PCIe ezihambisanayo, ngoba noma ngabe i-PCIe 5.0 SSD ingasebenza endaweni engu-4.0, ngeke ifinyelele isivinini sayo esiphezulu sethiyori.
Umehluko obalulekile phakathi kwe-HDD ne-SSD: isivinini, umthamo, umsindo, nokuningi
Uma sesiqonda ukuthi zisebenza kanjani, sekuyisikhathi sokubheka ukuthi yini ozoyibona ngempela ekusetshenzisweni kwansuku zonke: ukusebenza, izikhathi zokuqalisa, umthamo, ukusetshenziswa kwamandla, kanye nomsindo . Yilapho igebe langempela phakathi kwama-SSD nama-HDD livuleka khona. Uma ufuna ukuthola izinkinga zokusebenza ezihlobene nediski, hlola umhlahlandlela wethu ngezikhathi zokuqalisa.
Uma uqhathanisa isikhathi sokuqalisa sesistimu yokusebenza efakwe kwi-HDD kanye ne-SSD, umehluko ushesha: i-SSD ingaqalisa uhlelo cishe ngemizuzwana eyi-7 kumakhompyutha amaningi anamuhla, kuyilapho i-HDD engu-7200 RPM ithatha kalula ubude obuphindwe kabili, cishe imizuzwana eyi-15-20 , kuye ngemodeli kanye ne-hardware esele.
Ngokuphathelene nokudluliselwa kwamafayela amakhulu, i-HDD evamile isebenza ngesivinini sokufunda/ukubhala esilandelanayo phakathi kuka -100 no-200 MB/s , ngezinye izikhathi esingaphansi kumamodeli angu-5400 RPM. I-SATA SSD ivame ukufinyelela cishe ku- 400-550 MB/s , kanti i-NVMe PCIe 3.0 SSD ingafinyelela kalula ku- 3.000 MB/s , kuyilapho ama-PCIe 4.0 kanye nama-5.0 drives ephindaphinda lezo zibalo futhi. Ezivivinyweni ezithile, ama-HDD abonwe efunda ku-150 MB/s uma kuqhathaniswa nama-SATA SSD cishe ku- 500-550 MB/s.
Umehluko awukho nje kuphela esivinini esingakahleleki; isikhathi sokufinyelela okungahleliwe (lapho uhlelo lugxuma lusuka kwelinye ifayela luye kwelinye) yilapho i-HDD ihluleka khona. I-SSD iphatha imisebenzi yokufunda/yokubhala emincane, engavamile ngokushesha kaningi, okuholela ekuqalisweni kohlelo olusheshayo, izikhathi zokulayisha umdlalo ezimfushane , kanye nomuzwa ophelele wobushelelezi i-HDD engenakuwufanisa.
Nokho, maqondana nomthamo omkhulu, i-HDD isabusa kakhulu. Kuvamile ukubona ama-hard drive omshini angu- 8, 10, noma ngaphezulu ngamanani angabizi kakhulu, kuyilapho ama-SSD abathengi ngokuyinhloko esukela ku -256 GB kuya ku-4 TB , kanye namamodeli angu-8 TB atholakalayo kodwa abiza kakhulu. Intengo nge-gigabyte ngayinye ye-SSD ivame ukujikeleza cishe ku- €0,08-$0,10 nge-GB , kuyilapho i-HDD ingehla iye ku- €0,03-$0,06 nge-GB . Ukuze uhlale usesikhathini ngezitayela zamanani kanye nezindaba zemboni, hlola isigaba sethu sezindaba zesitoreji.
Ukuhlukana, umsindo, usayizi ongokoqobo, kanye nokusetshenziswa
Enye yezinkinga ezinde ngama-hard disk drive (ama-HDD) ukuqhekeka . Ngenxa yokuthi idatha ibhalwa kuma-plate ajikelezayo, i-drive isebenza kahle kakhulu uma amafayela amakhulu egcinwa njalo ku-disk: lokhu kuvumela ikhanda lokufunda/lokubhala ukuthi lidlule lonke ifayela ngokunyakaza okukodwa. Njengoba i-disk igcwala, amafayela ayaqhekeka futhi asakazeke ezindaweni ezahlukene, okuphoqa ikhanda lokufunda/lokubhala ukuthi ligxume lisuka endaweni eyodwa liye kwenye, ngaleyo ndlela kwandisa isikhathi sokufinyelela.
Ukuhlukana akuyona inkinga yangempela ngama-SSD ngoba isikhathi sokufinyelela kunoma yiliphi iseli sicishe sifane kungakhathaliseki ukuthi likuphi ngokomzimba. Ngakho-ke, akusizi ngalutho ukusebenzisa amathuluzi endabuko okuhlukana ku-SSD; empeleni, ukuqhubeka nokwenza kanjalo kunganciphisa kancane isikhathi sayo sokuphila ngokuphoqa ukubhala okungadingekile. Izinhlelo zokusebenza zesimanje seziyaqonda lokhu futhi zisebenzisa imisebenzi ethile yokulungisa efana ne-TRIM esikhundleni salokho . Uma udinga ukwenza ngcono isikhala nokusebenza ku-Windows, lo mhlahlandlela ungakusiza ukuthi ukhulule isikhala futhi uthuthukise ukusebenza.
Enye indawo yokuqhathanisa umsindo . Ngisho nama-HDD athule kakhulu akhipha umsindo omncane lapho ama-platter ejikeleza futhi kuzwakala ukuchofoza lapho ikhanda lokufunda/lokubhala lihamba, okubonakala kakhulu kumamodeli angu-7200 noma angu-10.000 RPM. Kuma-drive asetshenziswa kakhulu, lo msindo ungaba yinto ecasulayo. I-SSD, engenazo izingxenye ezihambayo, ayikhiqizi msindo nhlobo , okuyinzuzo enkulu kuma-desktop athule, kuma-studio okuqopha, noma kuma-laptop okusebenza buthule.
Ngokuphathelene nosayizi obonakalayo, ama-HDD anqunyelwe ububanzi bama-plate kanye nendlela yokufunda/ukubhala ikhanda, yingakho ama-2,5″ nama-3,5″ kuyizilinganiso ezijwayelekile. Ama-SSD, ngakolunye uhlangothi, angaba mancane kakhulu: kusukela kumamojula e-M.2 amancane kunomunwe kuya kuma-drive angu-2,5″ avaliwe. Lokhu kuvumela ukwakheka kwama -ultrabook amancane kakhulu, ama-laptop alula, namadivayisi angenayo indawo ye-HDD yendabuko.
Ngokuphathelene nokusetshenziswa kwamandla, i-SSD ivame ukusebenzisa cishe ama-watts angu-4-5 uma igcwele , kanye nama-chips asebenza ngama-voltage aphansi kakhulu (1,2V ezimweni eziningi). I-HDD, enenjini yayo ejikeleza ama-plate futhi inyakazise ikhanda lokufunda/lokubhala, isebenzisa amandla amaningi futhi ivame ukusebenza nge- 12V ngesixhumi samandla se-SATA. Umehluko ngeke uthinte kakhulu ibhili yakho kagesi, kodwa ungathinta impilo yebhethri ye-laptop kanye nosayizi wohlelo lokunikezwa kwamandla kanye nokupholisa. Uma unesifiso sokwenza ngcono ukusetshenziswa kwamandla, hlola umhlahlandlela wethu mayelana nokuphathwa kwamandla e-PC.
Ukuqina, ukumelana nokushaqeka kanye nokuphila isikhathi eside
Uma sikhuluma ngokuthi idrayivu ihlala isikhathi esingakanani, kufanele sihlukanise imiqondo emibili: ukumelana ngokomzimba nokushaqeka nokudlidliza kanye nesikhathi sokuphila kobuchwepheshe bokugcina (i-magnetism ku-HDD, amaseli e-NAND ku-SSD).
I-hard disk drive (i-HDD) iqukethe izingxenye ezithambile kakhulu zomshini: ama-platter ajikeleza kuma-RPM ayizinkulungwane kanye nekhanda lokufunda/ukubhala elihamba ngama-micron ambalwa ukusuka ebusweni. Ukushaqeka ngesikhathi sokusebenza kungabangela ukuthi ikhanda lithintane ne-platter futhi lonakalise ubuso obunamandla, okuholela ezigabeni ezimbi noma, esimweni esibi kakhulu, ukulahleka kwedatha iyonke. Yingakho zifaneleka kangcono kumakhompyutha edeskithophu angasebenzi kunokuba zithwaleke kalula.
Ngakolunye uhlangothi, i-SSD imelana nokunyakaza futhi iwela kangcono kakhulu, njengoba konke kufakwe ebhodini lesekhethi elingenazo izingxenye ezihambayo . Ikakhulukazi kuma-2,5" ama-form factor anezimbobo zepulasitiki noma ze-aluminium, ziqinile kakhulu ekushayweni ngengozi, okwenza zilungele ama-laptop, amaphilisi, ama-console, kanye nama-drive angaphandle ahamba kusukela emhlane kuya edeskini nsuku zonke.
Ngokuphathelene nokuphila kwesikhathi, i-HDD ayinawo umkhawulo wokubhala ocacile wethiyori, njengoba idatha igcinwa ngamandla kazibuthe ngaphandle kokuthintana ngokomzimba ngqo. Ukuguguleka kwayo kubangelwa kakhulu ukukhathala komshini kwezingxenye , ikhwalithi yokukhiqiza, amahora okusebenza, kanye nezimo zokushisa. Kuvamile ukubona amadrayivu adlula kalula iminyaka engu-8-10 yesevisi , yize kwenzeka ukwehluleka ngaphambi kwesikhathi.
Ama-SSD anomkhawulo wokubhala, ovame ukulinganiswa nge -TBW (okubhaliwe ngama-terabytes) noma iminyaka yewaranti. Iseli ngalinye le-NAND lisekela inani elilinganiselwe lemijikelezo yokubhala nokusula, ehlukahluka kuye ngokuthi yi-SLC, i-MLC, i-TLC, noma i-QLC. Kodwa-ke, empeleni, le mikhawulo iphakeme kakhulu ukusetshenziswa ekhaya. Izifundo, ezifana nokuhlolwa kokukhuthazela okwenziwe kumamodeli adumile (isibonelo, i-Samsung 850 Pro), zikhombisile ukuthi zingamelana nama-petabytes angaphezu kuka-2,4 edatha ebhaliwe ngaphambi kokwehluleka, okungaphezu kakhulu kwalokho umsebenzisi ojwayelekile azokubhala kukho konke ukuphila kwedrayivu.
Ngokwesiko, ama-SSD ayegxekwa ngezinga lawo lokwehluleka kanye nokubuyiselwa kwedatha: izizukulwane zokuqala zazivame ukuba nezinkinga, futhi uma izinto zikagesi zihluleka, ukubuyisa idatha kungaba yinkimbinkimbi kakhulu futhi kubize kakhulu kune-HDD. Nakuba ukuthembeka kuye kwathuthuka ngesizukulwane ngasinye, ama-SSD anamuhla avela kumikhiqizo edumile ngokuvamile abhekana nokwehluleka okuncane kakhulu eminyakeni yawo yokuqala embalwa , ukugcina ama-backup kusabalulekile.
Ukuthembeka, ukubuyisa idatha, kanye nokusekela ngokulondoloza idatha
Ama-SSD noma ama-HDD awaphelele: noma iyiphi idrayivu ingahluleka ngenxa yephutha lokukhiqiza, ukwanda kwamandla, umthelela, noma ukumane iguge. Isu langempela lokuvikela izithombe zakho, amadokhumenti, namaphrojekthi akukhona ukukhetha uhlobo olulodwa lwedrayivu kunolunye, kodwa kunalokho ukugcina amakhophi amaningi kumidiya ehlukene yokugcina.
Uma kwenzeka inhlekelele, ukubuyisa idatha kuma-hard drive ngokuvamile kungabizi kakhulu futhi kungenzeka: ngoba kuyimidiya yamagnetic, ama-plate avame ukwenziwa ama-clone noma kufakwe izingxenye zomshini ezindaweni zokucwaninga ezikhethekile. Kodwa-ke, uma umonakalo unzima kakhulu, inqubo izobiza kakhulu.
Ngama-SSD, izinto ziba nzima kakhulu. Lawa ma-drive asebenzisa amasu angaphakathi njengokweqa izinga kanye ne-TRIM , okubhala kabusha nokuhlela kabusha idatha ngemuva. Ngaphezu kwalokho, lapho ibhulokhi imakwe njengekhululekile futhi isuswa, okuqukethwe kwayo akukwazi ukutholwa ngezindlela ezivamile. Ngakho-ke, uma isilawuli se-SSD sehluleka noma kukhona ukonakala kwezinga eliphansi, ukululama kochwepheshe kungaba nzima kakhulu noma kungenzeki.
Ukuze unciphise izingozi, inkambo ehlakaniphile kakhulu yesenzo ukusebenzisa umthetho wakudala wokuba namakhophi okungenani amabili noma amathathu edatha yakho ebalulekile : isibonelo, i-SSD eyinhloko ku-PC yakho, i-HDD yangaphandle yokulondoloza njalo, kanye, uma kungenzeka, ikhophi eyengeziwe efwini noma kwenye idrayivu egcinwe endaweni ehlukile. Lokhu kubaluleke kakhulu kumafayela angenakushintshwa njengezithombe zomndeni noma amadokhumenti abalulekile.
Uma ufuna isitoreji "esibandayo"—okungukuthi, idrayivu engasetshenziswa kakhulu futhi engeke isetshenziswe isikhathi esiningi eshalofini—zombili ama-HDD nama-SSD ziyizinketho ezisebenzayo. Kodwa-ke, kuyalulekwa ukuwasebenzisa izikhathi ezimbalwa ngonyaka , uhlole isimo sawo se-SMART, uqinisekise ukuthi konke kufundwe kahle, futhi, uma amaphutha eqala ukuvela, thutha idatha iye kudrayivu entsha. Ukuze uthole izinketho zokugcina nokuvumelanisa ezingaphandle kwendawo, cabanga futhi ngesitoreji samafu njengokwengeza.
I-SSD vs i-HDD yama-backups kanye nesitoreji sesikhathi eside
Umbuzo ovamile uthi hlobo luni lwedrayivu okufanele ulusebenzisele ukwenza isipele sesikhathi eside: i-HDD yangaphandle yakudala noma i-SSD yangaphandle? Uma uzoxhuma idrayivu izikhathi ezimbalwa ngonyaka ukuze wengeze izithombe noma amavidiyo engeziwe, zombili izinketho zinezinzuzo kanye nokungalungi okufanele kucatshangelwe.
Ama-hard drive angaphandle anikeza amandla aphezulu ngentengo ephansi futhi azibonakalise eyindlela yokusekela eqinile iminyaka eminingi. Angahlala iminyaka engu-7-10 noma ngaphezulu ngokunakekelwa okufanele, yize ezwela ukushaqeka nokudlidliza, ikakhulukazi uma esetshenziswa. Ukuze uwagcine edroweni futhi uwaxhume ngezikhathi ezithile, ahlala eyindlela engcono kakhulu futhi engabizi.
Ama-SSD angaphandle abiza kakhulu ngomthamo ofanayo, kodwa anikeza ukuqina okuphezulu ngokomzimba, ukuthula okuphelele, kanye nesivinini sokufunda nokubhala esisheshayo. Ukusetshenziswa ngezikhathi ezithile, lapho ungasoze wafinyelela umkhawulo we-TBW, ukuguga kokubhala akuyona inkinga engokoqobo. Ukukhathazeka okuyinhloko ngokuvamile ukwehluleka kwe-elekthronikhi noma kweseli ngenxa yokuguga, yize imiklamo yamanje ithuthuke kakhulu.
Uma sikhuluma nje ngesitoreji esibandayo sesikhathi eside , imidiya ye-optical esezingeni eliphezulu (njenge-Blu-ray M-DISC) isalokhu iyinketho eqinile kakhulu, kodwa emazweni amaningi kunzima ukuyithola futhi akulula ukuyisebenzisa njenge-hard drive yangaphandle. Empeleni, kubasebenzisi abaningi, inhlanganisela ye-HDD kanye/noma i-SSD kanye nama-backups efu kuyindlela engokoqobo yokuvikela amafayela abo.
Isu elinengqondo kungaba ukusebenzisa i -SSD njengedrayivu eyinhloko yesistimu yokusebenza kanye nezinhlelo zokusebenza, kanye ne-HDD eyodwa noma ngaphezulu yangaphandle yokwenza amakhophi avamile . Ngale ndlela, usebenzisa isivinini se-SSD sokusetshenziswa kwansuku zonke kanye nezindleko eziphansi nge-terabyte ngayinye ye-HDD yokugcina umlando wokwenza amakhophi amarekhodi ngaphandle kokusebenzisa imali eningi.
Yikuphi okungcono nge-laptop noma i-desktop PC?
Kukhompyutha ephathekayo yesimanje, ikakhulukazi imodeli encane noma ephakathi nendawo/ephezulu, ukukhetha kusobala impela: i -SSD iyimpoqo cishe . Hhayi nje kuphela ngesivinini, kodwa futhi ngoba inesisindo esincane, ithatha isikhala esincane, isebenzisa amandla amancane, futhi imelana kakhulu namaqhubu nokushayisana okungenza ikhompyutha ikwazi ukubekezelela ukusuka ekhaya iye emsebenzini, eyunivesithi iye esitimeleni, njll. Uma ubona izikhathi zokuqalisa ezihamba kancane kanye nezikhathi zokulayisha, umhlahlandlela wethu uzokusiza.
Ama-laptop amaningi esimanje, kufaka phakathi ama-ultrabook nama-laptop emidlalo, manje asebenzisa ama-SSD e-M.2 NVMe kuphela . Lokhu kuvumela izikhathi zokuqalisa ezisheshayo kakhulu, ukulayisha imidlalo okusheshayo kakhulu, kanye nokuhlangenwe nakho okubushelelezi kakhulu. Ngaphezu kwalokho, ama-SSD asiza ama-laptop ukuba abe mancane, alula, futhi athule - into engenakwenzeka nge-HDD enkulu nezingxenye zayo ezihambayo.
Ku-PC yedeskithophu, isinqumo sivumelana nezimo kancane, kodwa isincomo esilinganiselayo kakhulu ngokuvamile ukuhlanganisa ubuchwepheshe bobabili: ukufaka uhlelo lokusebenza nezinhlelo ku-SSD (okungcono kakhulu i-NVMe) bese usebenzisa i-HDD eyodwa noma ngaphezulu njengesitoreji sesibili semidlalo, ama-backup, amavidiyo, umculo noma amafayela amakhulu angafuni kakhulu.
Ngemisebenzi edinga ukufinyelela okujulile kwidiski, njengokuhlela ividiyo, ukusebenza ngezithombe ezinesinqumo esiphezulu, imishini ebonakalayo, noma imidlalo yevidiyo yesimanje , i-SSD yenza umehluko omkhulu. Ezimweni eziningi, ukushintsha kusuka ku-HDD kuya ku-SSD kuzwakala njengokuthuthuka okukhulu kunokuthuthukisa iprosesa noma i-RAM, ikakhulukazi ezinhlelweni esezivele zine-RAM okungenani engu-8-16 GB.
Uma isabelomali sakho sincane kakhulu futhi ungakwazi ukukhokhela idrayivu eyodwa kuphela, ngokuvamile kungcono ukukhetha i -SSD encane kune-HDD enkulu: uzobona umehluko nsuku zonke. Ungahlala ungeza isitoreji esengeziwe nge-HDD yangaphakathi noma yangaphandle kamuva uma uyidinga.
Intengo kanye nenani lemali phakathi kwe-SSD ne-HDD
Izindleko nge-gigabyte ngayinye ziseyimpikiswano eyinhloko esekela ama-HDD, yize igebe ngama-SSD belilokhu lincipha unyaka nonyaka ngenxa yokusetshenziswa kabanzi kwememori ye-flash kumaselula, ama-laptop, amaseva kanye namadivayisi azo zonke izinhlobo.
Namuhla ungathola ama-1TB SATA noma ama-NVMe SSD ngamanani aphansi kakhulu, kwezinye izimo cishe afana ne-HDD enamandla afanayo, ikakhulukazi kumamodeli asezingeni lokuqala. Ama-1TB M.2 NVMe PCIe 4.0 SSDs manje ayatholakala cishe ngama- €50 , okwenza ukwakha i-PC eqinile ngokuphelele kufinyeleleke kalula kunaseminyakeni embalwa edlule.
Ama-HDD, okwamanje, agcina ukubusa kwawo endaweni yokugcina izinto enamandla aphezulu: uma udinga ama-terabyte angu-8, 10, noma ngaphezulu , i-SSD yalowo mthamo iba yindleko enkulu kakhulu, kuyilapho i-hard drive yomshini ihlala ingabizi kakhulu. Yingakho eqhubeka nokuba ukukhetha okunengqondo kwamadivayisi e-NAS asekhaya, amaseva amafayela, ama-backups amakhulu , noma amaqoqo amakhulu amavidiyo.
Kufanele futhi ucabangele "izindleko zesikhathi": i-SSD, nakuba ibiza kakhulu, ingakongela amahora okulinda phakathi kokulayisha, ama-backup, izikhathi zokuqalisa, kanye nezinye izinqubo ezidinga izinsiza eziningi . Uma usebenzisa ikhompyutha yakho emsebenzini noma ekufundeni, lokhu kukhulisa umkhiqizo kungakhokhela umehluko wezindleko zokuqala.
Ngamafuphi, uma ubheka isabelomali esifanayo, ngokuvamile kuhlakaniphile ukukhetha amandla amancane kodwa ku-SSD ukuze kusetshenziswe kakhulu uhlelo, bese ubeka ama-HDD endaweni yokugcina yesibili lapho kudingeka khona amavolumu amakhulu ngentengo ephansi.
Iyiphi i-albhamu ongayikhetha kuye ngesimo sakho: izimo ezingokoqobo
Uma usebenzisa ikhompyutha yakho ngokuyinhloko ukuphequlula, izinhlelo zokusebenza zehhovisi, ukusakaza ividiyo, kanye neminye imisebenzi elula , i-SSD kufanele ibe yidrayivu yakho eyinhloko, noma ngabe ingu-240-500 GB kuphela. Uzoqaphela ukuthi iWindows noma uhlelo lwakho lokusebenza oluthandayo luqala ngokushesha, izinhlelo zokusebenza zivuleka ngokushesha, futhi ikhompyutha izizwa isabela kakhulu.
Uma uvame ukulanda okuqukethwe okuningi (ama-movie, izinhlelo ze-TV, imidlalo emikhulu) noma usebenza namafayela evidiyo angu-4K, izithombe ze-RAW, noma ama-backups amakhulu , i-HDD enkulu isasebenza kahle kakhulu ekugcineni konke lokho ngaphandle kokuchitha imali eningi. Kulesi simo, ikhambi elingcono kakhulu ngokuvamile i-SSD yesistimu yokusebenza kanye ne-HDD njengedrayivu yesibili yangaphakathi noma yangaphandle.
Ukuze usethe imidlalo, kungcono ukuthi ube ne -NVMe SSD eyodwa okungenani yesistimu yokusebenza kanye nemidlalo yakho esetshenziswa kakhulu; izikhathi zokulayisha zincishiswa kakhulu, futhi uthola ukusebenza okungcono kusuka ekubunjweni kanye nedatha elayisha uma kudingeka. I-HDD eyengeziwe ingasetshenziswa ukugcina izihloko ezingadlali njalo noma imitapo yolwazi emikhulu engadingi izikhathi zokulayisha ezisheshayo kanjalo.
Uma ukukhathazeka kwakho okuyinhloko ukugcina izithombe zomndeni kanye nemibhalo ebalulekile isikhathi eside, noma iyiphi inketho (i-HDD noma i-SSD) kufanele ihambisane namakhophi angafuneki. Ungasebenzisa i-HDD yangaphandle enamandla aphezulu ukuze wenze amakhophi avamile, futhi uma isabelomali sakho sivuma, i-SSD yangaphandle encane, esheshayo ukuze ugcine ama-albhamu akamuva noma amaphrojekthi aqhubekayo etholakala kalula. Njalo faka lokhu ngekhophi engaphandle kwendawo, isibonelo, kudivayisi yokugcina.
Ekugcineni, esikhundleni sokubuza ukuthi "i-SSD noma i-HDD?", isihluthulelo siwukucabanga ukuthi iyiphi inhlanganisela efanela kangcono ukusetshenziswa kwakho, isabelomali, kanye nezidingo zokugcina . I-SSD inikeza isivinini, ukusebenza okuthule, kanye nokuqina; i-HDD inikeza umthamo ongabizi kanye nesikhathi eside njengesitoreji sokugcina. Ukuzihlanganisa ngempumelelo kukuvumela ukuthi usebenzise okungcono kakhulu kwalokhu ngaphandle kokudela noma yini ebalulekile.
Ngemva kokubona indlela ezisebenza ngayo ngaphakathi, izinzuzo kanye nokungalungi kwazo ngokwejubane, umthamo, umsindo, ukusetshenziswa kwamandla, ukuqina, kanye nentengo, kusobala ukuthi ama-SSD athathe indawo njengedrayivu eyinhloko yanoma iyiphi ikhompyutha yesimanje , kuyilapho ama-HDD egcina indima ebalulekile njengesixazululo sokugcina izinto eziningi kanye nesipele esingabizi kakhulu. Ngesu elihle elihlanganisa zombili izinhlobo zamadrayivu kanye nezipele eziphindaphindwayo, ungaba nekhompyutha esheshayo, ethule, nethembekile ngaphandle kokusebenzisa imali eningi noma ukubeka idatha yakho ebaluleke kakhulu engozini.
