В Ochungechungeni oluthi "Isingeniso ku-SSD", sikhulume ngomlando wokubukeka kwamadiski. Ingxenye yesibili izokhuluma ngama-interfaces okuxhumana namadrayivu.
Ukuxhumana phakathi kwephrosesa kanye namadivayisi we-peripheral kwenzeka ngokuya ngezivumelwano ezichazwe ngaphambilini ezibizwa ngokuthi i-interfaces. Lezi zivumelwano zilawula izinga lomzimba kanye nesofthiwe yokusebenzisana.
Isixhumi esibonakalayo isethi yamathuluzi, izindlela nemithetho yokusebenzisana phakathi kwezakhi zesistimu.
Ukusetshenziswa ngokomzimba kwesixhumi esibonakalayo kuthinta amapharamitha alandelayo:
- umthamo wesiteshi sokuxhumana;
- inombolo enkulu yamadivayisi axhumeke ngasikhathi sinye;
- inani lamaphutha enzekayo.
Izixhumi ezibonakalayo zediski zakhelwe phezu kwazo Izimbobo ze-I/O, okuphambene ne-memory I/O futhi ayithathi isikhala endaweni yekheli lomprosesa.
Izimbobo ezihambisanayo nezilandelanayo
Ngokwendlela yokushintshana kwedatha, amachweba we-I/O ahlukaniswe abe izinhlobo ezimbili:
- ukuhambisana;
- engaguquki.
Njengoba igama liphakamisa, imbobo ehambisanayo ithumela igama lomshini elihlanganisa izingcezu ezimbalwa ngesikhathi. Imbobo ehambisanayo iyindlela elula yokushintshanisa idatha, njengoba ingadingi izixazululo eziyinkimbinkimbi. Esimeni esilula, igama ngalinye lomshini lithunyelwa ngomugqa walo wesignali, futhi imigqa yesignali yesevisi emibili isetshenziselwa impendulo: Idatha isilungile и Idatha yamukelwe.
Izimbobo ezihambisanayo zibonakala zikhula kahle kakhulu lapho uqala nje: imigqa yesignali eyengeziwe isho ukuthi izingcezu eziningi zidluliswa ngesikhathi, ngakho-ke, ukuphuma okuphezulu. Kodwa-ke, ngenxa yokwanda kwenani lemigqa yesignali, ukuphazamiseka kwenzeka phakathi kwabo, okuholela ekuhlanekeni kwemilayezo edlulisiwe.
Izimbobo ze-serial ziphambene nezimbobo ezifanayo. Idatha ithunyelwa kancane ngesikhathi, okunciphisa inani eliphelele lemigqa yesignali kodwa yengeza inkimbinkimbi kusilawuli se-I/O. Isilawuli se-transmitter sithola igama lomshini ngesikhathi futhi kufanele sidlulise kancane kancane ngesikhathi, futhi isilawuli esamukelayo kufanele sithole izingcezu futhi sizigcine ngokulandelana okufanayo.
Inombolo encane yemigqa yesignali ikuvumela ukuthi ukhuphule imvamisa yokudluliswa komlayezo ngaphandle kokuphazanyiswa.
SCSI
I-Small Computer Systems Interface (SCSI) yavela emuva ngo-1978 futhi ekuqaleni yayiklanyelwe ukuhlanganisa amadivaysi amaphrofayili ahlukahlukene abe yisistimu eyodwa. Ukucaciswa kwe-SCSI-1 kuhlinzekelwe ukuxhuma kufika kumadivayisi angu-8 (kanye nesilawuli), njengalokhu:
- izikena;
- ama-tape drives (ama-streamers);
- ama-optical drives;
- amadrayivu ediski namanye amadivaysi.
I-SCSI ekuqaleni ibibizwa nge-Shugart Associates System Interface (SASI), kodwa ikomidi lezindinganiso alizange livume igama ngemuva kwenkampani, futhi ngemva kosuku lokuxoxisana, kwazalwa igama elithi Small Computer Systems Interface (SCSI). "Ubaba" we-SCSI, u-Larry Boucher, wayehlose ukuthi isifinyezo sibizwe ngokuthi "sexy", kodwa Ngifunde elithi “scuzzy” (“ngitshele”). Kamuva, ukuphinyiselwa kwegama elithi “skazi” kwabelwa ngokuqinile kuleli zinga.
Kumatemu e-SCSI, amadivaysi axhunyiwe ahlukaniswe abe izinhlobo ezimbili:
- abaqalisi;
- amadivayisi okuqondiwe.
Umqalisi uthumela umyalo kudivayisi eqondiwe, bese ithumela impendulo kumqalisi. Abaqalisi nokuhlosiwe kuxhunywe ebhasini elivamile le-SCSI, elinomkhawulokudonsa ongu-1 MB/s kuzinga le-SCSI-5.
I-topology "yebhasi evamile" esetshenziswayo ibeka inani lemikhawulo:
- Emaphethelweni ebhasi, kudingeka amadivaysi akhethekile - ama-terminators;
- Umkhawulokudonsa webhasi wabiwa phakathi kwawo wonke amadivaysi;
- Inombolo enkulu yamadivayisi axhumeke ngesikhathi esisodwa inqunyelwe.
Amadivayisi ebhasi ahlonzwa ngenombolo eyingqayizivele ebizwa I-ID Yethagethi ye-SCSI. Iyunithi ngayinye ye-SCSI ohlelweni imelelwa okungenani idivayisi eyodwa enengqondo, eqondiswa kusetshenziswa inombolo ehlukile ngaphakathi kwedivayisi ephathekayo. Inombolo Yeyunithi Enengqondo (LUN).
Imiyalo ye-SCSI ithunyelwa njenge amabhlogo encazelo yomyalo (Command Descriptor Block, CDB), ehlanganisa ikhodi yokusebenza namapharamitha womyalo. Izinga lichaza imiyalo engaphezu kuka-200, ihlukaniswe izigaba ezine:
- okugunyaziwe - kumele isekelwe idivayisi;
- Akuphoqelekile - kungenziwa;
- Ngokuqondene nomthengisi - esetshenziswa umakhi othize;
- Kuphelelwe isikhathi - imiyalo ephelelwe yisikhathi.
Phakathi kwemiyalo eminingi, emithathu kuphela yayo eyimpoqo kumadivayisi:
- ISIVIVINYO SESILUNGILE — ukuhlola ukulungela kocingo;
- CELA UMUZWA - icela ikhodi yephutha yomyalo odlule;
- INQUIRY - isicelo sezimpawu eziyisisekelo zocingo.
Ngemva kokuthola nokusebenzisa umyalo, idivayisi eqondiwe ithumela umqalisi ikhodi yesimo echaza umphumela wokwenza.
Ukuthuthukiswa okuqhubekayo kwe-SCSI (ukucaciswa kwe-SCSI-2 kanye ne-Ultra SCSI) kunwebise uhlu lwemiyalo esetshenzisiwe futhi kwandisa inani lamadivayisi axhunyiwe laya ku-16, kanye nesivinini sokushintshana kwedatha ebhasini safinyelela ku-640 MB/s. Njengoba i-SCSI iyisixhumi esibonakalayo esihambisanayo, ukukhulisa imvamisa yokushintshisana kwedatha kwahlotshaniswa nokuncipha kobude bekhebula obukhulu futhi kwaholela ekuphazamisekeni ekusebenziseni.
Ukuqala ngezinga le-Ultra-3 SCSI, usekelo “lwe-hot plugging” luvele - amadivayisi axhumayo ngenkathi ugesi uvuliwe.
Idrayivu yokuqala eyaziwayo ye-SSD ene-SCSI interface ingabhekwa njenge-M-Systems FFD-350, ekhishwe ngo-1995. Idiski yayibiza kakhulu futhi yayingandile.
Njengamanje, i-SCSI ehambisanayo ayisona isixhumi esibonakalayo sokuxhunywa kwediski, kodwa isethi yomyalo isasetshenziswa ngenkuthalo ku-USB ne-SAS interface.
I-ATA/PATA
isikhombikubona I-ATA (I-Advanced Technology Attachment), eyaziwa nangokuthi I-PATA (Parallel ATA) yathuthukiswa yi-Western Digital ngo-1986. Igama lokumaketha lezinga le-IDE (I-Integrated Drive Electronics) ligcizelele into entsha ebalulekile: isilawuli sedrayivu sakhelwe kudrayivu, kunokuba sakhelwe ebhodini lokunweba elihlukile.
Isinqumo sokubeka isilawuli ngaphakathi kwedrayivu sixazulule izinkinga ezimbalwa ngesikhathi esisodwa. Okokuqala, ibanga ukusuka kudrayivu kuya kusilawuli lehlile, okunomthelela omuhle ezicini zedrayivu. Okwesibili, isilawuli esakhelwe ngaphakathi "sasilungiselelwe" kuphela uhlobo oluthile lokushayela futhi, ngokufanele, lwalushibhile.
I-ATA, njenge-SCSI, isebenzisa indlela ye-I/O efanayo, ethinta izintambo ezisetshenzisiwe. Ukuxhuma amadrayivu usebenzisa isixhumi esibonakalayo se-IDE, izintambo ezinezintambo ezingu-40, ezibizwa nangokuthi izintambo, ziyadingeka. Ukucaciswa kwakamuva kakhulu kusebenzisa amaluphu ezintambo ezingu-80: ngaphezu kwengxenye yawo angamalophu aphansi ukuze kuncishiswe ukuphazamiseka kumafrikhwensi aphezulu.
Ikhebula le-ATA linezixhumi ezisuka kwezimbili kuya kwezine, esinye sazo esixhunywe ebhodini lomama, kanti okunye kumadrayivu. Lapho uxhuma amadivaysi amabili ngekhebula elilodwa, enye yazo kufanele imiswe njenge Master, kanti eyesibili - njenge Isigqila. Idivayisi yesithathu ingaxhunywa ngemodi yokufunda kuphela.
Indawo ye-jumper icacisa indima yedivayisi ethile. Amagama athi Inkosi Nesigqila ngokuphathelene namadivayisi awalungile ngokuphelele, njengoba maqondana nesilawuli wonke amadivaysi axhunyiwe ayizigqila.
Ukuqamba okusha okukhethekile ku-ATA-3 ukubukeka Ukuziqapha, Ukuhlaziya Nokubika Ubuchwepheshe (SMART). Izinkampani ezinhlanu (i-IBM, i-Seagate, i-Quantum, i-Conner ne-Western Digital) zihlanganyele amandla kanye nobuchwepheshe obujwayelekile bokuhlola impilo yamadrayivu.
Ukusekelwa kwamadrayivu e-solid-state kuvele nenguqulo yesine yezinga, ekhishwe ngo-1998. Le nguqulo yezivinini ezijwayelekile zokudlulisa idatha ezifika ku-33.3 MB/s.
Izinga libeka phambili izidingo eziqinile zezintambo ze-ATA:
- isitimela kufanele sibe flat;
- ubude besitimela esiphezulu ngamayintshi angu-18 (amasentimitha angu-45.7).
Isitimela esifushane nesibanzi besingalungile futhi siphazamisa ukupholisa. Kwaba nzima nakakhulu ukwandisa imvamisa yokudlulisela ngenguqulo ngayinye elandelayo yezinga, futhi i-ATA-7 ixazulule inkinga kakhulu: isikhombimsebenzisi esihambisanayo sathathelwa indawo yi-serial. Ngemva kwalokhu, i-ATA yathola igama elithi Parallel futhi yaziwa ngokuthi i-PATA, futhi inguqulo yesikhombisa yezinga yathola igama elihlukile - i-Serial ATA. Izinombolo zezinguqulo ze-SATA ziqale kweyodwa.
SATA
Izinga le-Serial ATA (SATA) lethulwa ngoJanuwari 7, 2003 futhi labhekana nezinkinga zomanduleli walo ngezinguquko ezilandelayo:
- imbobo ehambisanayo ithathelwe indawo eyisiriyali;
- intambo ebanzi enezintambo ezingu-80 ithathelwa indawo enezintambo ezingu-7;
- I-topology "yebhasi evamile" ithathelwe indawo ngoxhumano lwe-"point-to-point".
Naphezu kweqiniso lokuthi izinga le-SATA 1.0 (SATA/150, 150 MB/s) lalishesha kancane kune-ATA-6 (UltraDMA/130, 130 MB/s), ukushintshela endleleni yokushintshisana ngedatha ye-serial “kwalungiselela umhlabathi” isivinini esikhuphukile
Imigqa yesignali eyishumi nesithupha yokudlulisa idatha ku-ATA ithathelwe indawo ngamapheya amabili asontekile: eyodwa ngeyokudlulisa, enye ngeyokwamukela. Izixhumi ze-SATA zenzelwe ukuthi zikwazi ukumelana nokuxhumeka okuningi, futhi imininingwane ye-SATA 1.0 yenza i-Hot Plug yenzeke.
Amanye amaphini kumadiski mafushane kunawo wonke amanye. Lokhu kwenziwa ukuze kusekelwe Ukushintshwa Okushisayo. Phakathi nenqubo yokushintsha, idivayisi "ilahlekelwa" futhi "ithola" imigqa ngokulandelana okunqunywe kusengaphambili.
Esikhathini esingaphezudlwana konyaka kamuva, ngo-April 2004, kwakhululwa inguqulo yesibili yokucaciswa kwe-SATA. Ngaphezu kokusheshisa kufika ku-3 Gbit/s, i-SATA 2.0 yethule ubuchwepheshe Umugqa womyalo womdabu (NCQ). Amadivayisi anokwesekwa kwe-NCQ akwazi ukuhlela ngokuzimela uhlelo lapho imiyalo etholiwe ibulawa khona ukuze kuzuzwe ukusebenza okuphezulu.
Eminyakeni emithathu eyalandela, i-SATA Working Group yasebenza ukuthuthukisa ukucaciswa okukhona futhi kunguqulo 2.6 compact Slimline kanye nezixhumi ze-SATA ezincane (uSATA) zavela. Lezi zixhumi ziyinguqulo encane yesixhumi se-SATA sangempela futhi zenzelwe amadrayivu okukhanya namadrayivu amancane kumalaptop.
Nakuba isizukulwane sesibili se-SATA sasinomkhawulokudonsa owanele wama-hard drive, ama-SSD ayedinga okwengeziwe. NgoMeyi 2009, inguqulo yesithathu yokucaciswa kwe-SATA yakhululwa ngomkhawulokudonsa okhuphukile waba ngu-6 Gbit/s.
Ukunakwa okukhethekile kukhokhwe kumadrayivu e-solid-state kuhlelo lwe-SATA 3.1. Kuvele isixhumi seMini-SATA (mSATA), esiklanyelwe ukuxhuma amadrayivu e-solid-state kumakhompyutha aphathekayo. Ngokungafani ne-Slimline ne-SATA, isixhumi esisha sasifana ne-PCIe Mini, nakuba sasingahambisani ngogesi ne-PCIe. Ngokungeziwe kusixhumi esisha, i-SATA 3.1 iziqhayise ngekhono lokubeka umugqa imiyalo ye-TRIM ngemiyalo yokufunda nokubhala.
Umyalo we-TRIM wazisa i-SSD ngamabhulokhi edatha angawuthwali umthwalo okhokhelwayo. Ngaphambi kwe-SATA 3.1, ukwenza lo myalo kungabangela ukuthi izinqolobane zisuswe futhi i-I/O izomiswa, kulandelwe umyalo we-TRIM. Le ndlela yehlisa ukusebenza kwediski ngesikhathi sokusebenza kokususa.
Ukucaciswa kwe-SATA akukwazanga ukuhambisana nokukhula okusheshayo kwezivinini zokufinyelela kumadrayivu aqinile, okuholele ekubonakaleni ngo-2013 kokuvumelana okubizwa nge-SATA Express ku-SATA 3.2 standard. Esikhundleni sokuphinda kabili umkhawulokudonsa we-SATA futhi, abathuthukisi basebenzise ibhasi le-PCIe elisetshenziswa kabanzi, ijubane layo lidlula i-6 Gbps. Amadrayivu asekela i-SATA Express athole eyawo isici sefomu ebizwa ngokuthi i-M.2.
SAS
Izinga le-SCSI, "elincintisana" ne-ATA, nalo alizange lime lithule futhi ngemva nje konyaka ngemva kokuvela kwe-Serial ATA, ngo-2004, laphinde lazalwa njengesikhombimsebenzisi se-serial. Igama lesixhumi esibonakalayo esisha lithi I-Serial Inamathiselwe i-SCSI (SEDGE).
Ngaphandle kweqiniso lokuthi i-SAS izuze isethi yomyalo we-SCSI, izinguquko bezibalulekile:
- isikhombimsebenzisi se-serial;
- Intambo yamandla engu-29;
- iphuzu-kuya-iphuzu uxhumano
Amagama e-SCSI nawo azuzwa njengefa. Isilawuli sisabizwa ngokuthi isiqalisi, futhi amadivayisi axhunyiwe asabizwa ngokuthi ithagethi. Wonke amadivayisi aqondiwe kanye nesiqalisi sakha isizinda se-SAS. Kwa-SAS, ukuxhumana okudlulayo akuncikile enanini lamadivayisi esizindeni, njengoba idivayisi ngayinye isebenzisa isiteshi sayo esizinikele.
Inombolo enkulu yamadivayisi axhumeke ngasikhathi sinye esizindeni se-SAS ngokuya ngencazelo idlula izinkulungwane eziyi-16, futhi esikhundleni se-ID ye-SCSI, isihlonzi sisetshenziswa ekhelini. Igama Lomhlaba Wonke (WWN).
I-WWN iyinkomba eyingqayizivele engamabhayithi angu-16 ubude, efana nekheli le-MAC lamadivayisi we-SAS.
Ngaphandle kokufana kwezixhumi ze-SAS ne-SATA, lawa mazinga awahambisani ngokuphelele. Nokho, idrayivu ye-SATA ingaxhunywa kusixhumi se-SAS, kodwa hhayi okuphambene nalokho. Ukuhambisana phakathi kwamadrayivu e-SATA nesizinda se-SAS kuqinisekiswa kusetshenziswa i-SATA Tunneling Protocol (STP).
Inguqulo yokuqala yezinga le-SAS-1 inomphumela we-3 Gbit/s, futhi yesimanje kakhulu, i-SAS-4, ithuthukise lesi sibalo izikhathi ezingu-7: 22,5 Gbit/s.
PCIe
I-Peripheral Component Interconnect Express (PCI Express, PCIe) iyisixhumi esibonakalayo esiwuchungechunge sokudluliswa kwedatha, esavela ngo-2002. Ukuthuthukiswa kwaqalwa yi-Intel, futhi kamuva yadluliselwa enhlanganweni ekhethekile - Iqembu Lezithakazelo Ezikhethekile ze-PCI.
I-serial PCIe interface ayihlukile futhi yaba ukuqhubeka okunengqondo kwe-PCI efanayo, eklanyelwe ukuxhuma amakhadi okunweba.
I-PCI Express ihluke kakhulu ku-SATA ne-SAS. I-PCIe interface inenombolo eguquguqukayo yemizila. Inombolo yemigqa ilingana namandla amabili futhi isukela ku-1 kuye ku-16.
Igama elithi "umzila" ku-PCIe alibhekiseli emugqeni wesignali othize, kodwa esiteshini esisodwa sokuxhumana esinezimbaxa ezimbili ezihlanganisa imigqa yesiginali elandelayo:
- ukwamukela+ nokwamukela-;
- ukudluliswa+ nokudluliswa-;
- izintambo ezine eziphansi.
Inombolo yemigqa ye-PCIe ithinta ngokuqondile umkhawulo ophezulu wokuphuma koxhumano. Izinga lesimanje le-PCI Express 4.0 likuvumela ukuthi uzuze u-1.9 GB/s emugqeni owodwa, kanye no-31.5 GB/s uma usebenzisa imigqa engu-16.
Isifiso sokudla amadrayivu e-solid-state sikhula ngokushesha kakhulu. Kokubili i-SATA ne-SAS abanaso isikhathi sokukhulisa umkhawulokudonsa wabo ukuze “uhambisane” nama-SSD, okuholele ekuveleni kokushayela kwe-SSD ngoxhumo lwe-PCIe.
Nakuba amakhadi e-PCIe Add-In efakwe ngokujikijelwayo, i-PCIe iyashintshashintsha. Izikhonkwane ezimfushane ze-PRSNT (IsiNgisi esikhona - samanje) zikuvumela ukuthi uqinisekise ukuthi ikhadi lifakwe ngokuphelele endaweni.
Amadrayivu e-Solid-state axhunywe nge-PCIe alawulwa yizinga elihlukile Ukucaciswa Kwesilawuli Sesilawuli Sokusingatha Inkumbulo Engaguquguquki futhi ahlanganiswe ngezindlela ezahlukahlukene zefomu, kepha sizokhuluma ngazo engxenyeni elandelayo.
Amadrayivu akude
Lapho kwakhiwa izindawo zokugcina idatha ezinkulu, kwaphakama isidingo sezivumelwano ezivumela ukuxhuma amadrayivu atholakala ngaphandle kweseva. Isixazululo sokuqala kule ndawo kwaba I-SCSI ye-inthanethi (iSCSI), yathuthukiswa yi-IBM kanye neCisco ngo-1998.
Umqondo wephrothokholi ye-iSCSI ulula: Imiyalo ye-SCSI “isongwe” kumaphakethe we-TCP/IP futhi idluliselwe kunethiwekhi. Ngaphandle kokuxhumeka okukude, inkohliso idalelwe amaklayenti ukuthi idrayivu ixhunywe endaweni. I-iSCSI-based Storage Area Network (SAN) ingakhiwa kwingqalasizinda yenethiwekhi ekhona. Ukusebenzisa i-iSCSI kunciphisa kakhulu izindleko zokuhlela i-SAN.
I-iSCSI inenketho ethi “premium” - I-Fiber Channel Protocol (I-FCP). I-SAN esebenzisa i-FCP yakhelwe phezu kwemigqa yokuxhumana ye-fiber optic ezinikele. Le ndlela idinga imishini eyengeziwe yenethiwekhi ye-optical, kodwa izinzile futhi inokuphuma okuphezulu.
Kunamaphrothokholi amaningi okuthumela imiyalo ye-SCSI ngamanethiwekhi ekhompyutha. Kodwa-ke, kunendinganiso eyodwa kuphela exazulula inkinga ephambene futhi ivumela amaphakethe we-IP ukuthi athunyelwe ngebhasi le-SCSI - .
Amaphrothokholi amaningi e-SAN asebenzisa umyalo we-SCSI osethi ukuze ulawule amadrayivu, kodwa kukhona okuhlukile, njengokulula I-ATA nge-Ethernet (AwuE). Iphrothokholi ye-AoE ithumela imiyalo ye-ATA kumaphakethe e-Ethernet, kodwa amadrayivu avela njenge-SCSI ohlelweni.
Ngokufika kwamadrayivu e-NVM Express, izivumelwano ze-iSCSI ne-FCP azisahlangabezani nezidingo ezikhula ngokushesha zama-SSD. Kuvele izixazululo ezimbili:
- ukuhambisa ibhasi le-PCI Express ngaphandle kweseva;
- ukwakhiwa kwephrothokholi ye-NVMe phezu kwezindwangu.
Ukususa ibhasi le-PCIe kuhilela ukudala imishini yokushintsha eyinkimbinkimbi, kodwa akuguquli umthetho olandelwayo.
Iphrothokholi ye-NVMe phezu kwezindwangu isiphenduke enye indlela enhle ye-iSCSI ne-FCP. I-NVMe-oF isebenzisa isixhumanisi se-fiber optic kanye nesethi yemiyalo ye-NVM Express.
I-DDR-T
Amazinga e-iSCSI kanye ne-NVMe-oF axazulula inkinga yokuxhuma amadiski akude njengawasendaweni, kodwa i-Intel ithathe umzila ohlukile futhi yaletha idiski yendawo eduze ngangokunokwenzeka kumprosesa. Ukukhetha kuwele kuzikhala ze-DIMM lapho i-RAM ixhumeke khona. Umkhawulokudonsa omkhulu wesiteshi se-DDR4 ngu-25 GB/s, ophakeme kakhulu kunejubane lebhasi le-PCIe. Le yindlela i-Intel® Optane™ DC Persistent Memory SSD eyazalwa ngayo.
Iphrothokholi yasungulwa ukuze kuxhunywe amadrayivu kuzikhala ze-DIMM I-DDR-T, ngokomzimba nangokogesi kuhambisana ne-DDR4, kodwa kudinga isilawuli esikhethekile esibona umehluko phakathi kwe-memory stick ne-drive. Isivinini sokufinyelela sedrayivu sihamba kancane kune-RAM, kodwa sishesha kune-NVMe.
I-DDR-T itholakala kuphela ngama-Intel® Cascade Lake processors noma akamuva.
isiphetho
Cishe zonke izindlela zokusebenzelana zihambe ibanga elide ukusuka ezindleleni zokudlulisa idatha ezihambisanayo. Isivinini se-SSD sikhula ngokushesha; izolo nje ama-SSD abeyinto entsha, kodwa namuhla i-NVMe ayisamangazi ikakhulukazi.
Elabhorethri yethu ungahlola i-SSD kanye ne-NVMe drive ngokwakho.
Abasebenzisi ababhalisiwe kuphela abangabamba iqhaza kuhlolovo. , wamukelekile.
