Njengamanje, ukushayela okuqinile kombuso kancane kancane kususa amadrayivu ajwayelekile ajwayelekile. Uma muva nje, ama-SSD ayeyivolumu encane futhi, njengomthetho, asetshenziselwa ukufaka uhlelo, manje sekuvele kukhona ama-1 ama-Jerabyte angama-disc nokunye okuningi. Izinzuzo zemihubhelo enjalo zisobala - zithule, isivinini esikhulu nokuthembeka. Namuhla sizonikeza izeluleko eziningana zendlela yokwenza ukukhetha kwama-CD.
Izimpawu eziningana ze-SSD
Ngaphambi kokuthenga i-disk entsha, kufanele unake amapharamitha amaningi azosiza ekukhetheni idivaysi efanelekile yohlelo lwakho:- Nquma ngevolumu ye-SSD;
- Thola ukuthi yiziphi izindlela zokuxhuma ezitholakala ohlelweni lwakho;
- Naka "ukugcwaliswa" kwe-disk.
Kungenxa yalezi zinhlamvu lapho sizokhetha i-drive, ngakho-ke ake sibheke ngamunye wabo ngemininingwane eminingi.
Umthamo we-disc
Ukushayela okuqinile kombuso kusebenza isikhathi eside kunawo wonke ama-disc, okusho ukuthi ngeke uwutholele unyaka owodwa. Kungakho kufanelekile ukuthi kusondele kakhulu ekukhetheni ivolumu.
Uma kuhlelwe ukusebenzisa i-CEDU ngaphansi kohlelo nohlelo, khona-ke kuleli cala idrayivu engu-128 gb iphelele. Uma ufuna ukufaka esikhundleni ngokuphelele i-disk ejwayelekile, khona-ke kulokhu kufanelekile ukucubungula amadivaysi ngevolumu ye-512 GB.
Ngaphezu kwalokho, ngokungajwayelekile ngokwanele, umthamo wediski uthinta impilo yenkonzo, kanye nesivinini sokufunda / sokubhala. Iqiniso ngukuthi ngenani elikhulu le-drive, isilawuli sinendawo enkulu yokusabalalisa umthwalo kumaseli wememori.
Izindlela zokuxhuma
Njengasendabeni yanoma iyiphi enye insiza, i-SSD emsebenzini kumele ixhunywe kwikhompyutha. Izindlela zokuxhumana ezivame kakhulu yi-SATA ne-PCIE. I-Disc nge-PCIE interface isivinini esiningi uma kuqhathaniswa ne-SATA futhi kuvame ukwenziwa njengemephu. Ukushayela kwe-SATA kube nokubukeka okuhle, futhi futhi kungokwendawo yonke, ngoba bangaxhuma kwikhompyutha nakwi-laptop.
Kodwa-ke, ngaphambi kokuthenga idiski, kufanelekile ukubheka ukuthi ngabe kukhona izixhumi zamahhala ze-PCIE noma ama-SATA ebhodini lomama.
I-M.2 kungenye interface yokuxhuma ye-SSD engasebenzisa ibhasi le-SATA ne-PCI-Express (PCIE). Isici esiyinhloko samadiski anesixhumi esinjalo ukuhlanganiswa. Sekukonke, kunezinketho ezimbili zesixhumi - nge-Key B noM. Ziyahluka ngenani le "cutouts". Uma esimweni sokuqala (ukhiye c) kukhona ukusikwa okukodwa, bese kuba okwesibili - kukhona ezimbili zazo.
Uma uqhathanisa ukuxhumeka kwe-Speed interfaces, i-PCIE, lapho izinga lokudlulisa idatha lingafinyelela ku-3.2 GB / s. Kepha i-SATA ifinyelela ku-600 MB / s.
Uhlobo lwememori
Ngokungafani ne-HDD evamile, idatha igcinwe ekudleni okuqinile kombuso ngememori ekhethekile. Manje ama-disc atholakala ngezinhlobo ezimbili zale memory - MLC ne-TLC. Kuluhlobo lwememori olunquma insiza kanye nejubane ledivayisi. Amanani aphezulu kakhulu azoba ngamadiski ngohlobo lwememori ye-MLC, ngakho-ke kungcono ukuyisebenzisa uma uvame ukukopisha, susa noma ukuhambisa amafayela amakhulu. Kodwa-ke, izindleko zama-disc anjalo ziphakeme kakhulu.
Bona futhi: Ukuqhathaniswa kwezinhlobo zememori ye-NAND Flash
Kumakhompyutha amaningi asekhaya, amadiski anohlobo lwememori ye-TLC aphelele. Ngejubane, baphansi kwe-MLC, kepha namanje bedlula amadivayisi ajwayelekile okugcina.
Abakhiqizi be-chip bala abalawuli
Hhayi indima yokugcina ekukhetheni ama-disc kudlala abakhiqizi be-chip. Ngamunye wabo unezinhle nezinzuzo zawo. Ngakho-ke, abalawuli abasuselwa kuma-sandforce chips bathandwa kakhulu. Zinezindleko eziphansi nokusebenza okuhle. Ukungafani kwalezi zinhlamvu ukusebenzisa ukucindezela kwedatha lapho kuqoshwa. Kulokhu, kunenkinga ebalulekile - lapho ugcwalisa idiski ngaphezulu kwesigamu, funda / bhala isivinini sehla kakhulu.
Ama-Marvel chip disc anesivinini esihle kunazo zonke amaphesenti okugcwaliswa angathintekanga. Iphutha kuphela lapha izindleko eziphakeme.
I-Samsung ibuye ikhiqize ama-chips wokushayela okuqinile kombuso. Isici sinjalo - ukubethela ezingeni lehadiwe. Kodwa-ke, banephutha. Ngenxa yezinkinga nge-algorithm yomhlangano kaGaresig, funda / wokubhala ungancipha.
Ama-chizon chips abonakala ngokusebenza okuphezulu nezindleko eziphansi. Azikho izici ezithonya ijubane, kepha ngakolunye uhlangothi, azikhombisa kahle ngerekhodi nokufunda ngokungacabangi.
I-LSI-sandforce ingenye umenzi wama-chips wezilawuli zokushayela eziqinile. Imikhiqizo yalo mkhiqizi ihlangane kaningi. Isici esisodwa yidatha yokucindezela ngesikhathi sokudluliselwa ku-NAnd Flash. Ngenxa yalokhu, inani lemininingwane erekhodwe liyancishiswa, elisindisa insiza ngqo. Okubi ukunciphisa ukusebenza kwezilawuli kumthwalo omkhulu wememori.
Futhi ekugcineni, umenzi wokugcina wama-chips yi-Intel. Abalawuli ngesisekelo salezi zinhlamvu bazibonakalise zivela kuzo zonke izinhlangothi, kepha babiza kakhulu kunezinye.
Ngaphezu kwalokho kubakhiqizi abaphambili, kukhona abanye. Isibonelo, kumamodeli wesabelomali sama-disks, ungathola abalawuli ngokususelwa kuma-jmicron chips, abhekana kahle nemisebenzi yabo, yize izinkomba zalezi zinhlamvu ziphansi kunalezo zokuphumula.
Ama-Disc
Cabanga amadiski ambalwa ahamba phambili esigabeni sakho. Njengezigaba, thatha ivolumu yedrazili uqobo.I-Discs kuze kufike ku-128 GB
Kulesi sigaba, amamodeli amabili we-Samsung MZ-7ke128bb angahlukaniswa ngamanani afinyelela kuma-ruble ayizinkulungwane ezingama-8000 kanye ne-Intel SSDSC2BM120A401, izindleko zawo zihlukahluka kusuka kuma-ruble angama-4,000 kuye kwangama-5,000.
Imodeli ye-Samsung MZ-7ke128bw ibonakala ngesivinini esiphakeme sokufunda / sokubhala esigabeni sayo. Ngenxa yecala elincanyana, liphelele ukufakwa e-ultrabook. Kungenzeka ukusheshisa umsebenzi ngokwabiwa kwe-RAM.
Izici eziyinhloko:
- Isivinini sokufunda: Ama-Mbs angama-550
- Qopha ijubane: 470 MBPS
- Isivinini sokufunda okungahleliwe: ama-iops ayi-100000
- Isivinini sokuqopha okungahleliwe: ama-iops angama-90000
IOSS inani lamabhulokhi akwazi ukubhalisela noma ukufundwa. Inkomba ephakeme, ikhuphuka ukusebenza kwensiza.
I-Intel SSDSC2BM120A401 drive ingenye ehamba phambili phakathi "kwabasebenzi bakahulumeni" ngevolumu efinyelela ku-128 GB. Ibonakala ngokuthembela okuphezulu futhi ilungele ukufakwa kwe-ultrabook.
Izici eziyinhloko:
- Isivinini sokufunda: 470 MBPS

Ama-disc ngevolumu ukusuka ku-128 kuya ku-240-256 gb
Lapha ummeleli omuhle kakhulu yi-sandisk sdsdxps-240g-g25 drive, izindleko zazo ezifinyelela ama-ruble ayizinkulungwane eziyi-12. Eshibhile, kepha ayikho imodeli esezingeni eliphakeme ephezulu yi-OCZ VTR150-5SAT3-240G (kuze kube yizinkulungwane ezingama-7 rubles).
Izici eziyinhloko zeCrucial CT256MX100SSD1:
- Isivinini sokufunda: 520 MBPS

Okukhishwayo
Ngakho-ke, sabheka izindlela eziningana zokukhethwa kwama-CD. Manje usungajwayelana nesiphakamiso nokusebenzisa imininingwane etholakele, ukunquma ukuthi iyiphi i-SSD ekulungele kahle wena nohlelo lwakho.
