- I-SSD inikeza isivinini sokudlulisa kanye namandla aphezulu kakhulu, okwenza kube ukukhetha okuhle kakhulu kwamakhompyutha kanye nemidlalo.
- Imemori ye-eMMC ishibhile futhi isebenzisa amandla amancane, kodwa ithengiswa kubhodi lomama, okuvimbela ukushintshwa kwayo.
- Zombili zisebenzisa ubuchwepheshe be-NAND flash, zisusa umsindo nokudlidliza okuvamile kumadiski amadala e-HDD omshini.
Uma uthenga i-laptop eshibhile, ithebhulethi, noma ngisho neselula, kuvamile kakhulu ukuhlangana namagama obuchwepheshe angasishiya sididekile kancane. Cishe usuvele uyazi ukuthi ama-hard drive amadala omshini, lawo anomsindo, ahamba kancane, manje aseyinto yesikhathi esidlule, athathelwe indawo ubuchwepheshe be-flash, obuphawula ukuphela kwesikhathi sokugcina idatha kanye nokuvela kwamadivayisi edatha . Kodwa-ke, akuyona yonke into ngaphandle kwezingxenye ezihambayo efanayo, futhi yilapho ama-drive e-eMMC nama-SSD eqala khona ukusebenza.
Nakuba zombili zisebenzisa i-NAND flash memory ukugcina amafayela akho ngisho noma idivayisi ivaliwe, izingxenye zazo zangaphakathi kanye nokusebenza kwazo kuhlukile kakhulu. Ukuze sigweme ukudumala lapho sikhetha idivayisi yakho elandelayo, sizobheka ngokuningiliziwe ukuthi iyini ngayinye nokuthi kungani ukukhetha kwakho isitoreji kungenza idivayisi yakho indize noma iqine uma uvula isiphequluli sewebhu esilula.
Iyini ngempela idrayivu ye-SSD?
Ama-SSD, noma ama-solid-state drive, empeleni ayizinto ezilandelayo ezinkulu kuma-USB flash drive. Ngokungafani nama-HDD endabuko, asebenzisa ama-spinning platets nama-physical read/write heads, ama-SSD agcina yonke into kuma- microchip e-flash memory axhunyiwe . Lokhu kuqeda noma yikuphi ukudlidliza futhi kwenza ikhompyutha ithule cishe.
Ubuchopho balezi zidrayivu yisilawuli, iprosesa ehlanganisiwe ephatha ukufunda nokubhala idatha, inquma ukuthi isula kanjani inkumbulo nokuthi igcina kuphi ulwazi. Lokhu kusebenza kahle kwesilawuli yikho okwenza umehluko wangempela ngesivinini sokugcina osizwayo uma uvula i-PC yakho.
Ngokuqondene nesici sazo sefomu, ngokuvamile ziyi-drive engu-2,5-intshi, ezivumela ukuthi zingene kahle ezindaweni lapho kwakukhona khona ama-hard drive enziwe ngomshini. Kodwa-ke, kunezinguqulo eziningi ezincane nezisheshayo ezingafinyelela isivinini esimangalisayo , njengoba kunjalo ngezixazululo zesitoreji se-NVMe kanye nebhizinisi , ezidlula kakhulu noma iyiphi enye indlela yokugcina isitoreji esikhulu.
Ukuchaza imemori ye-eMMC
Uma sikhuluma nge-eMMC (embedded MultiMediaCard), sibhekisela kubuchwepheshe obuvela kumakhadi e-MMC ngasekupheleni kwawo-90, okwandulela amakhadi e-SD esiwasebenzisa namuhla. Isihluthulelo lapha igama elithi "embedded," okusho ukuthi lithengiswa ngqo ebhodini lomama ledivayisi.
Lo mklamo yingakho uzozithola kakhulu kumafoni aphathekayo amancane kakhulu noma asezingeni eliphansi, amaphilisi, nama-laptop (njengamanye ama-Chromebook). Ngokuhlanganisa isilawuli kanye nememori ye-NAND ku-chip eyodwa, zonga isikhala namandla, okwenza zibe zilungele amadivayisi amancane angadingi amandla amakhulu.
Nakuba izinguqulo ezintsha, njenge-eMMC 5.1, zinesivinini sokudlulisa esiphezulu esifinyelela ku-400 MB/s, ukusebenza kwazo kwansuku zonke empeleni kuphansi. Zinezimbobo zememori ezimbalwa futhi azinazo izilawuli eziyinkimbinkimbi ezitholakala kuma-SSD, okuholela esivinini sokufunda okungahleliwe esiphansi kakhulu .
Ukuqhathanisa okuningiliziwe: i-eMMC vs i-SSD
Ukuze sikuqonde ngokushesha, singahlukanisa umehluko ube amaphuzu amaningana abalulekile athinta ngqo ulwazi lwakho lomsebenzisi:
- Umthamo wesitoreji: Nakuba i-eMMC ivame ukuba phakathi kuka-32 GB kuya ku-256 GB (njengoba kungavamile ukubona okungaphezu kwalokho), ama-SSD ngokuvamile aqala ku-128 GB futhi angakhula kalula afike ku-4 TB noma ngaphezulu ezindaweni zobungcweti.
- Isivinini sedatha: Amadrayivu e-eMMC ngokuvamile asukela ku-100 kuya ku-250 MB/s ekusetshenzisweni kwangempela. Ngokuphambene nalokho, i-SSD ingasukela ku-500 MB/s kumamodeli e-SATA iye ngaphezu kuka-3.000 MB/s kumadrayivu e-NVMe anamuhla.
- Intengo kanye nezindleko: I-eMMC ishibhile ngendlela emangalisayo, okuvumela intengo yokugcina ephansi yedivayisi. Ama-SSD abiza kakhulu, yize umehluko wentengo ungasabalulekile njengoba wawunjalo eminyakeni embalwa edlule.
- Ukusetshenziswa kwamandla: Ngenxa yokuthi iyisistimu elula kakhulu, i-eMMC isebenzisa amandla amancane, okusiza ibhethri lethebhulethi noma amaselula ahlala isikhathi eside.
Elinye iphuzu elibalulekile ukukhuliswa. Uma uthenga i-laptop ene-SSD, cishe uzokwazi ukuthuthukela kwenye enkulu esikhathini esizayo. Nge-eMMC, unamathela kunoma yini ikhompyutha eza nayo, ngoba i-soldered futhi ayinakushintshwa ngaphandle kokusebenzisa izinqubo zobuchwepheshe eziyinkimbinkimbi kakhulu.
Obunye ubuchwepheshe: Icala le-ROM
I-eMMC ngezinye izikhathi ididaniswa ne-ROM, kodwa izinto zihlukile. I-ROM (Inkumbulo Yokufunda Kuphela) uhlobo lwenkumbulo lapho idatha ibhalwa khona efektri futhi ingenakushintshwa kalula. Isetshenziselwa i-firmware noma i-BIOS, kuyilapho i-eMMC nama-SSD evumela idatha ukuthi ibhalwe futhi isulwe njalo.
Ngamafuphi, i-ROM yenzelwe imiyalelo engaguquki, i-eMMC yenzelwe ukugcina okulula nokungabizi kumadivayisi eselula, kanti i-SSD iyisilo esisebenzayo esenzelwe izinhlelo zokusebenza ezisindayo, imidlalo, kanye nokuhlela amavidiyo ochwepheshe.
Uma ufuna ikhompyutha yemisebenzi eyisisekelo njengokuphequlula iwebhu noma ukubuka izinhlelo ze-TV, idrayivu ye-eMMC ingase yanele futhi izokongela ama-euro ambalwa. Kodwa-ke, uma ufuna ikhompyutha engeke yehlise ijubane ngokuhamba kwesikhathi futhi ikuvumele ukuthi wandise isitoreji sayo esikhathini esizayo , ukukhetha i-SSD kuyisinqumo sesikhathi eside esihlakaniphile nesiphephile.
