- Ama-HDD asashibhile kakhulu nge-gigabyte ngayinye futhi alungele ukugcina idatha eningi.
- Ekusingatheni kanye nakumaseva, ama-SSD athuthukisa kakhulu izikhathi zokulayisha, imibuzo yesizindalwazi, kanye nokuzinza ngaphansi kokwanda kwethrafikhi.
- Inketho engcono kakhulu kubasebenzisi abaningi ukuhlanganisa i-SSD yesistimu nezinhlelo ne-HDD yedatha enkulu kanye nama-backups.
Uma unekhompyutha ene-hard drive yomshini futhi usanda kuyikhipha, kuvamile ukucabanga ukuthi "isebenza kahle, ivula ngokushesha, futhi iphendula kahle," bese uzibuza ukuthi ingabe kufanelekile ngempela ukusebenzisa imali kwi-SSD noma ngabe ukhokha nje ukuze wonge imizuzwana embalwa yesikhathi sokulinda. Iqiniso liwukuthi, yize i-HDD enakekelwe kahle ingasebenza kahle, ukugxuma uye kwi-solid-state drive kushintsha ngokuphelele isivinini esibonakalayo sekhompyutha yakho.
Kuyo yonke le ndatshana, sizochaza ngokuthula nangokucacile umehluko wangempela wokusebenza phakathi kwama-SSD nama-HDD , ukuthi asebenza kanjani ngaphakathi, ukuthi yimiphi imisebenzi ozoyibona intuthuko enkulu, ukuthi ahlala isikhathi esingakanani, ukuthi anaziphi izingozi, ukuthi asebenzisa amandla angakanani, futhi ngaphezu kwakho konke, ukuthi kufanele ukhethe ini noma enye (noma ukuyihlanganisa) kumakhompyutha, amaseva, ukusingathwa kwewebhu, kanye nakumhlahlandlela wethu wokuthuthukisa i-PC yakho.
Iyini i-HDD futhi isebenza kanjani?
I-hard disk drive yomshini, noma i-HDD (Hard Disk Drive), iyisistimu yokugcina yakudala esiyisebenzise kumakhompyutha amashumi eminyaka. Isekelwe kuma -plate ensimbi ajikeleza ngesivinini esikhulu ngaphakathi kwebhokisi elivaliwe. Ikhanda lokufunda/lokubhala lihamba phezu kwala ma-plate ukuze lithole idatha ngokoqobo.
Esikhundleni sokugcina idatha kuma-chips, i-HDD isebenzisa i-magnetism ukubhala nokufunda ulwazi ebusweni bama-plate ayo. Uma ama-plates emancane futhi ubuso bamagnetic buklanywe kangcono, ukuqopha kungaba yinkimbinkimbi futhi amandla amaningi angangena ngobukhulu obufanayo bomzimba, njengoba kuchazwe ubuchwepheshe be-HAMR.
Ijubane le-hard drive (HDD) lincike kakhulu ekuguqukeni ngomzuzu (RPM) lapho ama-plater ejikeleza khona, ngoba lokhu kunquma ukuthi ikhanda lokufunda/lokubhala lingathola futhi lidlulise idatha ngokushesha kangakanani . I-5400 RPM ijwayelekile kumakhompyutha amaningi asekhaya, kuyilapho ama-desktop ngokuvamile esebenzisa i-7200 RPM. Kodwa-ke, izindawo zobungcweti zinikeza ama-drive e-10.000 ngisho nangu-15.000 RPM aklanyelwe amaseva.
Ngokuphathelene nezici zefomu, osayizi be-HDD abavame kakhulu bangamasentimitha angu-3,5 kumakhompyutha edeskithophu kanye namasentimitha angu-2,5 kuma-laptop kanye nezinhlelo ezihlanganisiwe ( zombili ama-hard drive angaphakathi nangaphandle ). Inzuzo enkulu yama-hard drive omshini ukuthi anikeza amandla aphezulu kakhulu ngentengo ephansi kakhulu nge-gigabyte ngayinye , ngamamodeli asukela ku-1 TB kuya ku-10 TB (nangaphezulu) ngamanani afanele uma kuqhathaniswa nama-SSD.
Iyini i-SSD futhi ihluke kanjani?
I-Solid State Drive (SSD) isusa ngokuphelele izingxenye ezihambayo futhi esikhundleni salokho isebenzisa i-NAND flash memory exhunyiwe kuma-microchip ukugcina idatha, efana nama-SSD amancane, asheshayo, futhi athembekile . Empeleni, ifana "ne-USB flash drive enkulu, ethuthukisiwe kakhulu" enesilawuli sangaphakathi esiyinkimbinkimbi kakhulu.
Ngaphakathi kwe-SSD azikho izingqwembe noma amakhanda omshini, kodwa kuneprosesa ethile eyaziwa ngokuthi i-drive controller . Le chip inquma ukuthi idatha ihlelwa kanjani ngaphakathi kwamaseli ememori, ukuthi kusakazwa kanjani ukuguguleka, ukuthi isikhala esikhululekile sihlanzwa kanjani (i-TRIM), nokuthi kulawulwa kanjani ukufunda nokubhala ukuqinisekisa ukuthi konke kuhamba kahle ngangokunokwenzeka.
Amaseli enkumbulo ye-NAND flash awaguquguquki, okusho ukuthi awalahlekelwa ulwazi uma ikhompyutha icishiwe , njenge-HDD, kodwa avumela ukufinyelela kudatha cishe ngokushesha, ngaphandle kokulinda noma yini ukuthi ijikeleze noma inyakaze ngokomzimba. Yingakho umuzwa wejubane umangalisa kangaka, ngisho nasemisebenzini elula njengokuvula i-file explorer.
Ngokwesimo somzimba, ama-PC SSD amaningi asasebenzisa isikhombimsebenzisi se-SATA esingu-2,5-intshi, esiwavumela ukuthi athathe indawo ye-laptop noma i-desktop HDD ngaphandle kwezinkinga zokuhambisana . Ama-SSD ayatholakala futhi ngefomethi ye-M.2 nakumakhadi e-PCIe axhuma ngqo kubhodi lomama ukuze andise i-bandwidth ( i-PCIe optimization ).
Ngale kwefomethi, into ebalulekile ukuthi i-SSD yabathengi ejwayelekile inikeza amandla aphakathi kuka-256 GB no-4 TB, ngentengo iyonke iphakeme kunelingana ne-HDD, kodwa ngokushintshana nokuthuthuka okukhulu ekusebenzeni, umsindo, ukusetshenziswa kanye nokumelana nokushaqeka.
Umehluko obalulekile wokusebenza phakathi kwe-SSD ne-HDD
Ukuqhathaniswa kokusebenza phakathi kwama-SSD nama-HDD kungabukwa ngezindlela eziningana: izikhathi zokufinyelela, isivinini sokufunda/ukubhala, izikhathi zokuqalisa isistimu yokusebenza, kanye nokushelela okuphelele . Yilapho i-SSD yenza khona umehluko ngempela.
Ku-hard drive yomshini, isikhathi sokufinyelela idatha sincike ekutheni ikhanda lokufunda/lokubhala lihamba liye endaweni efanele futhi lilinde ukuthi ipuleti lijikeleze liye emkhakheni ofanele. Lokhu kusho ukuthi izikhathi zokufinyelela zingama-microsecond angu-5.000 kuya kwangu-10.000 , okungase kubonakale kufushane, kodwa kwenza umehluko omkhulu lapho uhlelo kufanele lufunde amafayela amancane ayizinkulungwane ngesikhathi esisodwa.
Ku-SSD, ukufinyelela kuqondile, ngaphandle kwezingxenye ezihambayo, futhi ukubambezeleka kuvame ukusuka kuma-microsecond angu-40 kuya kwangu-100 ukufunda ibhulokhi yedatha . Lokhu kusho ukuthi kushesha kaningi ngokwesikhathi sokufinyelela okungahleliwe, okuyilokho okuqaphelayo ngempela lapho uvula izinhlelo, imidlalo, noma amathebhu esiphequluli.
Uma sibheka isivinini esilandelanayo (ukukopisha amafayela amakhulu), i-HDD evamile yasekhaya inikeza isivinini sokufunda nokubhala esiphakathi kuka-100 no-150 MB/s , kuyilapho i-SATA SSD ingafinyelela cishe isivinini sokufunda esingu-500-550 MB/s kanye nesivinini sokubhala esingu-500 MB/s. Lokho kukodwa kumelela ukwanda kokusebenza okuphindwe kathathu noma kane kwalesi silinganiso esithile.
Uma sikhuluma ngama-NVMe SSD nge-PCIe, indaba iqhubekela phambili nakakhulu: kulula ukubona ama-drive akwazi ukuhambisa ama-2,2 GB/s ngaphezulu , futhi kumamodeli aphezulu adlula ama-3.500 MB/s, okungaphezulu kakhulu kwalokho okunganikezwa yinoma iyiphi i-hard drive yomshini, noma ngabe ijikeleza kuma-RPM aphezulu.
Empeleni, lokhu kusho ukuthi uhlelo lokusebenza olufakwe ku-SSD lungaqalisa cishe ngemizuzwana eyi-7, uma kuqhathaniswa nemizuzwana eyi-15-20 evamile ku -HDD engu-7.200 RPM. Futhi akusona isikhathi sokuqalisa nje kuphela: ukuvula umhleli wevidiyo, umdlalo onzima, noma iphrojekthi yokuklama akuseyona "indlela yokuhlola ifoni yakho" esheshayo kodwa imizuzwana embalwa nje yokulinda.
Ukusebenza kwe-SSD vs HDD ekusingatheni iwebhu nakumaseva
Uma sidlulisela lokhu kuqhathanisa kusuka kwi-PC yasekhaya kuya endaweni yeseva noma yokusingatha, umehluko uba sobala ngezikhathi zokulayisha amakhasi, isivinini sombuzo wedathabheyisi, kanye nokuzinza ngaphansi kokwanda kwethrafikhi . Endaweni yewebhu, konke kuhilela izicelo zokufunda nokubhala njalo.
Ekusingatheni ngama-HDD, njalo uma isivakashi sifinyelela ikhasi, iseva kufanele isebenzise amadiski omshini ukuze ifunde amafayela e-PHP, HTML, CSS, kanye ne-JavaScript, ifinyelele kusizindalwazi, njll. Lokhu kuphumela ezikhathini zokufinyelela ezinde kanye namathuba aphezulu okuvinjelwa lapho abasebenzisi abaningi befika ngesikhathi esisodwa.
Ekusingatheni okusekelwe ku-SSD, lawo mathuba afanayo okufinyelela enziwa ngama-microseconds nangesivinini esiphezulu esiqhubekayo, ngakho-ke iseva ingaletha amakhasi amaningi ngomzuzwana, ithuthukise isikhathi se-byte yokuqala (i-TTFB) , futhi iphathe kangcono ithrafikhi enkulu ngaphandle kokugcwala ngokweqile.
Ama-SSD nawo asiza ekunciphiseni umthwalo we-CPU kanye ne-RAM ngoba izinqubo azichithi isikhathi esiningi zilinde ukufinyelela kwediski , okuyinto empeleni ehunyushwa ibe amaseva azinzile kakhulu anesikhathi esincane sokulibala kanye nezikhathi zokuphendula ezihambisanayo ngisho nalapho izicelo zanda, futhi kufanelekile ukubuyekeza ukuphathwa kwememori ku-Linux.
Kumaphrojekthi anezizindalwazi ezinkulu, njengezitolo eziku-inthanethi, amaforamu, noma izinhlelo zokusebenza ze-SaaS, izinzuzo zama-SSD (ikakhulukazi i-NVMe) ziyanda, njengoba umbuzo ngamunye kanye nenkomba ngayinye kuxazululwa ngokushesha , kunciphisa ama-millisecond ekusebenzeni ngakunye, okuthi, uma sekuhlanganisiwe, kwenze umehluko omkhulu kokuhlangenwe nakho komsebenzisi.
Amandla, intengo kanye nenani elifanele kakhulu lemali
Esinye sezimpikiswano ezinkulu ezisekela ama-HDD ukuthi anikeza amandla amaningi ngemali efanayo . Isibonelo, kuvamile ukuthola ama-hard drive e-mechanical angu-4TB cishe ngama-€70-90, kuyilapho i-SSD engu-4TB ingabiza kalula ngaphezu kwama-€200, kuye ngemodeli.
Engxenyeni engezansi yebanga lentengo, ungathola ama-SATA SSD angaba ngu-240-256 GB ngamanani amancane , kodwa uma uwaqhathanisa nama-HDD, uzobona ukuthi ngentengo efanayo, ungathola ama-drive omshini angu-1 TB noma ngisho nama-2 TB. Yilapho abantu abaningi bengabaza khona: isivinini noma umthamo wesitoreji?
Ukusetshenziswa kwe-PC kwansuku zonke (uhlelo, izinhlelo kanye neminye imidlalo), i-SSD engu-250-500 GB ivame ukwanele futhi inikeza ulwazi olungcono kakhulu lomsebenzisi, kuyilapho isitoreji esiningi (ama-movie, ama-backup, amafayela ongawasebenzisi njalo) singadluliselwa kwi-HDD yesibili yama-terabytes amaningana.
Kumaseva kanye nokusingatha, izindleko nazo zidlala indima: umhlinzeki osebenzisa ama-SSD kuphela unezindleko zengqalasizinda eziphezulu , kodwa ngokubuyisela anganikeza izikhathi zokuphendula kanye nokusebenza okungcono, ikakhulukazi okubonakalayo kumasayithi anethrafikhi ephezulu noma okuqukethwe okuguquguqukayo.
Uma okubaluleke kakhulu kuwe indawo yokugcina futhi unesabelomali esincane, i-HDD iseyisinqumo esinengqondo. Kodwa-ke, uma ubheka ukusebenza ngaphezu kwakho konke futhi ungadingi ama-terabyte amaningana, i-SSD iyindlela enengqondo naphezu kwentengo yayo ephezulu nge-gigabyte . Futhi ezimweni eziningi, ikhambi elingcono kakhulu ukuhlanganisa kokubili.
Ukuqina, ukuthembeka kanye nezinga lokwehluleka
Eminyakeni embalwa yokuqala yama-SSD, kwakunokukhathazeka okukhulu ngokuqina kwawo ngoba amaseli awo enkumbulo anenani elilinganiselwe lemijikelezo yokubhala ngaphambi kokuba aguge . Kodwa-ke, ubuchwepheshe buthuthuke kakhulu kangangokuthi, ngaphansi kokusetshenziswa okuvamile, cishe uzoshintsha ikhompyutha yakho ngaphambi kokufinyelela lowo mkhawulo.
Izifundo ezizimele zibonise ukuthi ama-SSD asezingeni eliphakathi, njengamanye amamodeli e-Samsung, angaphatha kalula ama-petabytes amaningana edatha ebhaliwe - izibalo ezikude kakhulu nomsebenzisi ojwayelekile ngaphakathi kwesikhathi sokuphila sedivayisi. Noma kunjalo, isikhathi sokuphila esisemthethweni sivame ukuba yiminyaka emi-5-10, kuye ngokusetshenziswa kanye newaranti.
Ngokuphambene nalokho, ama-HDD awanakho umkhawulo wokubhala ngokwethiyori ku-magnetic medium, kodwa anezingxenye zemishini ezingagugi ngokomzimba : ama-motor, ama-bearings, amakhanda okufunda/ukubhala, njll. Ukushaqeka, ukudlidliza okunamandla, noma ukwehluleka kokugcoba kungalimaza idrayivu futhi kubangele noma yini kusukela emikhakheni emibi kuya ekuhlulekeni okukhulu. Idatha ingavame ukutholwa ngezinsizakalo zokubuyisa ezikhethekile, kanti nge-SSD enamaseli alimele noma isilawuli esifile, ukubuyisela kungaba nzima kakhulu noma kungenzeki nhlobo . Ngakho-ke, kuzo zombili izimo, ukusekela ngokulondoloza kuhlala kubalulekile.
I-MTBF, ukumelana nokushaqeka, izinga lokushisa nomsindo
Imininingwane eminingi ye-hard drive ifaka inombolo ebizwa ngokuthi i-MTBF (Mean Time Between Failures), okuyisilinganiso sezibalo samahora okusebenza phakathi kokwehluleka . Kuma-HDD asezingeni eliphezulu, amanani amahora ayizigidi ezingu-1,4 kuya kwezingu-2 avamile, kuyilapho ama-SSD nawo evame ukuthola amanani afanayo noma aphakeme kancane.
Ngale kwe-MTBF, kunezinye izilinganiso ezisebenzayo okufanele uzicabangele, njengokumelana nokushaqeka nokudlidliza . Idiski yomshini esebenza ngokuvamile imelana nokushaywa okungu-70-80 G, kuyilapho iphumule ingamelana kakhulu, yize ihlala iyisici esibucayi uma ihamba ngenkathi ijikeleza.
Ama-SSD, angenazo izingxenye ezihambayo, aqinile kakhulu uma ebhekene nokwehla, anezincazelo ezingafinyelela ku -1000G zokusheshisa ngaphansi kwezimo ezithile . Lokhu kuwenza afaneleke kakhulu kuma-laptop, imishini evame ukuthuthwa, noma izindawo ezinokudlidliza okuqhubekayo.
Ngokuphathelene nokushisa, cishe wonke ama-HDD asetshenziswa ngabathengi asebenza kahle phakathi kuka -5°C no-60°C , yize ukushisa okuhlala isikhathi eside kunciphisa ukuthembeka kwawo, futhi kuyalulekwa ukwazi ukuthi ungawaqapha kanjani amazinga okushisa ama-hard drive akho nama-SSD ku-Windows . Ama-SSD asekela amazinga abanzi, ezimweni eziningi afinyelela ku--60°C kuya ku-95°C, uma nje izinto zikagesi zipholile kahle futhi kungekho ukushisa okuningi okuchithekile kunalokho uhlelo olungakukhipha.
Ngokuphathelene nomsindo, umehluko ucacile: i-SSD ithule ngokuphelele, kuyilapho i-HDD ikhiqiza umsindo womshini ovela kuma-spindle kanye nama-read/write heads, angaba ngu-20-26 dB noma ngaphezulu kuye ngemodeli nesimo. Akuyona into ephula isivumelwano kubasebenzisi abaningi, kodwa uma ufuna i-PC ethule kakhulu, i-SSD ibaluleke kakhulu.
Ukusetshenziswa kwamandla nokushisa okukhiqizwayo
Uhlobo lwedrayivu luphinde luthinte ukusetshenziswa kwamandla, okuyisici esibalulekile kumaseva angu-24/7, ama-laptop, kanye namadivayisi e-NAS. I-SSD ejwayelekile engu-2,5-intshi ivame ukusebenzisa cishe ama-watts angu-1 kuya kwangu-2 ngaphansi kokusebenza okuvamile , incipha nakakhulu uma ingasebenzi, ngenxa yezimo zayo zamandla aphansi.
Ngakolunye uhlangothi, i-HDD idinga ukuhambisa njalo ama-plate kanye nekhanda lokufunda/lokubhala, okuhunyushwa ekusetshenzisweni kwamandla okungaba ngu -4 kuya ku-6 W uma isebenza , futhi ngisho nangaphezulu kancane kuma-drive asebenza kahle. Ngama-drive amaningi ku-server noma ku-storage array, umehluko wamandla uba mkhulu.
Ukusetshenziswa kwamandla aphezulu kwama-HDD kusho ukuthi akhiqiza ukushisa okwengeziwe ngaphakathi kwekhava , okudinga umoya ongcono futhi kungathinta ezinye izingxenye uma ukuhamba komoya kunganele. Abanye abakhiqizi basebenzise amasu afana nokugcwalisa ama-drive nge-helium esikhundleni somoya ukuze banciphise ukungqubuzana kwangaphakathi kanye nokushisa.
Ku-laptop, ukusebenzisa i-SSD kusiza ukwandisa impilo yebhethri kancane nokugcina amazinga okushisa aphansi, okusho ukuthi ifeni akudingeki isebenze ngesivinini esigcwele kaningi . Lokhu kubonakala kakhulu kuma-laptop amancane nalula.
Ezikhungweni zedatha noma kumaseva anamashumi noma amakhulu amayunithi, isamba salokho kusetshenziswa okuphansi ngediski ngayinye senza ukucushwa okusekelwe ku-SSD kusebenze kahle futhi kuqhubeke , yize utshalomali lokuqala luphezulu.
Indlela i-interface ebaluleke ngayo: i-SATA, i-NVMe, nokunye ukuxhumana
Ijubane ledrayivu ngokwayo aliyona yonke into: indlela exhuma ngayo ohlelweni nayo ibalulekile. Njengamanje, isikhombimsebenzisi esibanzi kakhulu sesitoreji sangaphakathi kuma-PC asekhaya yi- SATA III, enomkhawulo wethiyori ongu-6 Gb/s (cishe u-600 MB/s) , osevele uvimbela ama-SSD amaningi anamuhla.
Kuma-hard drive angaphandle, isikhombikubona esiyinhloko yi -USB 3.0 noma ngaphezulu , enikeza i-bandwidth efana ne-SATA III kanye nokuhambisana okujwayelekile. Kukhona nokuxhumana okufana ne-eSATA, i-Thunderbolt, kanye ne-USB-C okunezindlela ezihlukile, okuvumela isivinini esiphezulu kakhulu, kodwa lokhu akusabalele kakhulu kuwo wonke amadivayisi.
Ezweni lama-SSD, ijubane elikhulu lokusebenza liza ne -NVMe ngaphezu kwe-PCIe , exhumana ngqo nebhodi lomama futhi ingasebenza neziteshi eziningi ezihambisanayo. Lokhu kuyivumela ukuthi idlule kakhulu umkhawulo we-SATA: sikhuluma ngesivinini esingu-2,2 GB/s kumamodeli aphansi kanye nokunye okuningi kakhulu kumamodeli aphezulu.
Ama-HDD asasebenza kahle nge-SATA, ngoba isivinini sawo esingokoqobo asisondeli esilinganisweni esiphezulu se-interface. Kodwa-ke, ukuze usebenzise ngokugcwele i-SSD enamandla, kungcono ukuyifaka ku-M.2 NVMe slot noma ikhadi le-PCIe elizinikele , ikakhulukazi ezindaweni zokusebenza nakumaseva.
Kumaseva asebenza kahle kakhulu, inhlanganisela ye-NVMe, inani elihle le-RAM kanye ne-CPU enamandla ivumela ukusingatha izicelo eziningi ngasikhathi sinye ngaphandle kokuba isitoreji sibe yisithiyo , ikakhulukazi ezinhlelweni zokusebenza ezinezizindalwazi ezidinga kakhulu.
Izici zokusebenza zokubamba ngale kwediski
Nakuba uhlobo lwesitoreji (i-SSD noma i-HDD) luyisici esibalulekile, ukusebenza kokugcina kwesevisi yokubamba kuncike ekutheni iseva ihlelwe kanjani iyonke : i-RAM, i-CPU, ama-cache, isofthiwe, inethiwekhi, njll.
Umshini one-SSD kodwa inkumbulo encane noma iprosesa enganele ngokwanele usengasebenza kabi uma umhlinzeki engakabelani kahle izinsiza. Ngakho-ke, lapho ukhetha i-hosting, kubalulekile ukubheka ngale kwelogo evelele ethi "SSD" bese ucabangela inani le-RAM, uhlobo lwe-CPU, ukuthi ngabe basebenzisa i-NVMe, uhlelo lwe-caching (i-OPcache, i-Redis, i-Varnish, njll.), kanye nokuthi bangaki amaklayenti abelana ngehadiwe efanayo.
Omunye umkhuba ophumelelayo ukuhlanganisa izinhlobo ezahlukene zesitoreji ngaphakathi kweseva uqobo: i-NVMe yedatha efinyelelwa njalo , ama-SATA SSD edatha esetshenziswa ngokulingene, kanye nama-HDD okusekelayo noma okuqukethwe okungafinyelelwa njalo. Leli su lisebenzisa okungcono kakhulu kobuchwepheshe ngabunye.
Inqubomgomo yokusekela yomhlinzeki nayo inomthelela omkhulu : isevisi yokubamba egcina ama-backups avamile kuma-disk ahlukene noma kwenye indawo inciphisa umthelela wokwehluleka kwe-SSD noma i-HDD kanye , into engenzeka njalo kungakhathaliseki ukuthi idrayivu inhle kangakanani.
Ngamafuphi, uhlobo lwediski luyingxenye ebalulekile yephazili yokusebenza, kodwa ludinga ukuhambisana nokucushwa okulinganiselayo kwezinye izingxenye zeseva ukuze intuthuko ibonakale ngempela kumsebenzisi wokugcina.
Indlela yokukhetha: i-SSD, i-HDD, noma inhlanganisela yakho kokubili
Umbuzo obiza izigidi zamaRandi uthi: ngakho konke okungenhla, yini okufanele uyakhe? Ayikho impendulo eyodwa; kuncike ekusetshenzisweni okuhlosiwe, isabelomali, kanye nezinto eziza kuqala. Kodwa-ke, kunezindlela eziphindaphindayo ezingakusiza ukuthi unqume ngaphandle kokuzicasula ngokuqhathanisa imininingwane yobuchwepheshe.
Uma udinga ukugcina idatha eningi ngezindleko eziphansi kakhulu (ama-movie, ama-backup, amafayela ongawavuli nsuku zonke), i-HDD enkulu iyindlela enengqondo kakhulu. Uzothola ama-terabyte amaningana ngentengo efanelekile , wazi ukuthi ngeke ube nesivinini se-SSD, kodwa uzoba nesikhala esanele.
Ngakolunye uhlangothi, uma ufuna ikhompyutha yakho isheshe kakhulu lapho ivula izinhlelo, kungcono ukuthi uhlelo lokusebenza kanye nezinhlelo zokusebenza eziyinhloko zibe kwi-SSD, noma ngabe zincane . Umehluko ekusebenzeni uma uqhathaniswa ne-HDD mkhulu kakhulu, ngisho nasemakhompyutha amadala.
Inhlanganisela evamile kakhulu nenconywayo ukufaka i-SSD njengedrayivu eyinhloko (C:) yesistimu yokusebenza nezinhlelo, kanye ne-HDD yesibili yamafayela amakhulu. Ngale ndlela usebenzisa isivinini se-SSD semisebenzi yansuku zonke kanye nomthamo omkhulu wesitoreji se-HDD ngaphandle kokuchitha imali eningi.
Kuma-laptop anamuhla, cishe wonke amamodeli amahle afika ne-SSD njengejwayelekile ngoba anciphisa isisindo, umsindo, ukusetshenziswa kwamandla, kanye nobukhulu . Kulezi zimo, uma udinga isitoreji esengeziwe, ikhambi elingcono kakhulu ngokuvamile ukufaka i-HDD noma i-SSD yangaphandle, kuye ngezidingo zakho.
Kumaseva kanye nokusingatha, umthetho ojwayelekile uwukuthi kumawebhusayithi ashintshashintshayo, i-e-commerce, kanye nedathabheyisi, ama-SSD cishe ayimpoqo . Ama-HDD ancishiswa ekusetshenzisweni lapho isivinini singabalulekile khona: isitoreji esiyisipele, izindawo zokugcina amafayela amakhulu kakhulu angaguquki, njll.
Imibuzo evame ukubuzwa mayelana nokusebenza kwe-SSD vs HDD
Umbuzo ovame kakhulu ukuthi ngabe i-SSD "iyakusiza kuphela ukugwema izikhathi zokulinda isikhathi eside." Iqiniso liwukuthi ukuthuthuka kudlulela ngale kwesikhathi sokuqalisa: lonke uhlelo luba bushelelezi , kusukela ekuvuleni isiphequluli kuya ekususeni ukucindezela amafayela noma ekushintsheni amazinga emdlalweni. Lokhu kungonga isikhathi okuncane, okungaguquki okwenza umehluko omkhulu ekusetshenzisweni kwangempela.
Omunye umbuzo ovamile ukuthi ama-SSD ahlala isikhathi esincane yini. Namuhla, ngobuchwepheshe bokuguguleka kanye nobuchwepheshe bokwenza ngcono ukubhala, isikhathi sokuphila se-SSD yesimanje sifana noma sikhulu kunesama-HDD amaningi abathengi , uma nje imisebenzi yokubhala emikhulu nengalawulwa igwenywa.
Kuvamile futhi ukubuza ukuthi ngabe kufanelekile yini ukukhokha imali eningi ngedrayivu ye-NVMe uma kuqhathaniswa ne-SATA SSD ejwayelekile. Emisebenzini yansuku zonke (izinhlelo zokusebenza zehhovisi, ukuphequlula, ukusetshenziswa okulula), umehluko awubonakali kangako kunalapho ushintsha usuka kwi-HDD uye kwi-SSD , kodwa emisebenzini enzima njengokuhlela ividiyo, ukumodela kwe-3D, imishini ebonakalayo, noma amaseva alayishwe kakhulu, ukusebenza okwengeziwe kuyazuzisa impela.
Ekugcineni, abasebenzisi abaningi bayazibuza ukuthi i-SSD ingakwazi yini "ukulungisa" ikhompyutha endala. Uma nje ikhompyutha inokuxhumana okuhambisanayo, ukufaka i-HDD esikhundleni se-SSD ngokuvamile kuyindlela engcono kakhulu yokuthuthukisa ongayenza, okunikeza i-PC yakho impilo yesibili ngaphandle kokushintsha iprosesa, ibhodi lomama, noma imemori.
Njengoba konke lokhu kuqhubeka, kusobala ukuthi isinqumo phakathi kwe-SSD ne-HDD akuyona nje indaba yemfashini, kodwa kunalokho ibhalansi yokusebenza, amandla, ukuthembeka, kanye nesabelomali: i-SSD inikeza intuthuko enkulu ngesivinini kanye nokuhlangenwe nakho komsebenzisi, kuyilapho i-HDD ihlala iyinkosi yesitoreji esishibhile, futhi ukuyihlanganisa ngobuhlakani kukuvumela ukuthi uthole okuningi kokubili kuye ngezidingo zakho zangempela.
