В umjikelo "Intshayelelo kwi-SSD" sathetha ngembali yokubonakala kweediski. Inxalenye yesibini iya kuxela malunga nojongano lokusebenzisana kunye needrives.
Unxibelelwano phakathi kweprosesa kunye neeperipherals lwenzeka ngokwemigaqo echazwe kwangaphambili ebizwa ngokuba yi-interfaces. Ezi zivumelwano zilawula umgangatho wonxibelelwano kunye nesoftware.
I-interface - isethi yeendlela, iindlela kunye nemithetho yokusebenzisana phakathi kwezinto zenkqubo.
Ukuphunyezwa ngokomzimba kojongano kuchaphazela ezi parameters zilandelayo:
- umsebenzi wejelo lonxibelelwano;
- inani eliphezulu lezixhobo eziqhagamshelwe ngaxeshanye;
- inani leempazamo ezenzekayo.
Ujongano lweDiski lwakhiwe I/O kumazibuko, echasene nenkumbulo ye-I/O kwaye ayithathi ndawo kwindawo yedilesi yomqhubekekisi.
Izibuko ezinxuseneyo nezilandelelanayo
Ngokwendlela yotshintshiselwano lwedatha, izibuko ze-I / O zahlulwe zibe ziindidi ezimbini:
- ngokuhambelana
- iyahambelana.
Njengoko igama lisitsho, izibuko elihambelanayo lithumela igama lomatshini ngexesha, eliquka amasuntswana amaninzi. I-port ehambelanayo yindlela elula yokutshintshiselana ngedatha, njengoko ayifuni izisombululo eziyinkimbinkimbi zesekethe. Kweyona meko ilula, isuntswana ngalinye legama lomatshini lithunyelwa kumgca walo wophawu, kwaye imigca yophawu lwenkonzo emibini isetyenziselwa impendulo: Idatha ilungile и Idatha yamkelwe.
Izibuko ezihambelanayo, ekubonweni kokuqala, zilinganisa kakuhle: imigca yesignali engaphezulu - iibhithi ezininzi zihanjiswa ngexesha kwaye, ngoko ke, ukuphakama okuphezulu. Nangona kunjalo, ngenxa yokwanda kwenani lemigca yesignali, ukuphazamiseka kwenzeka phakathi kwabo, okukhokelela ekugqwengeni kwemiyalezo ethunyelweyo.
Amazibuko othotho asisichasi se parallel. Idatha ithunyelwa kancinci ngexesha, elinciphisa inani elipheleleyo lemigca yesignali, kodwa inzima umlawuli we-I / O. Umlawuli we-transmitter ufumana igama lomatshini ngexesha kwaye kufuneka athumele isuntswana elinye ngexesha, kwaye umlawuli owamkelayo kufuneka afumane amasuntswana kwaye awagcine ngendlela efanayo.
Inani elincinci lemigca yesignali likuvumela ukuba ukwandise ukuphindaphinda kokuhanjiswa komyalezo ngaphandle kokuphazamiseka.
SCSI
I-Small Computer Systems Interface (SCSI) yavela emva kwe-1978 kwaye yayiyilwe ekuqaleni ukudibanisa izixhobo zeeprofayili ezahlukeneyo zibe yinkqubo enye. Iinkcukacha ze-SCSI-1 zibonelelwe ngokudityaniswa kwezixhobo ukuya kuthi ga kwi-8 (kunye nomlawuli), njenge:
- iiskena;
- ii-tape drives (i-streamers);
- iidrive zokukhanya;
- iidisk drives kunye nezinye izixhobo.
I-SCSI yayibizwa ngokuba yi-Shugart Associates System Interface (SASI), kodwa ikomiti yemigangatho ayiyi kuvuma igama emva kwenkampani, kwaye emva komhla wokucamngca, igama elithi Small Computer Systems Interface (SCSI) lazalwa. Uyise we-SCSI, uLarry Boucher, wayefuna ukuba igama elithi "sexy" libizwe ngokuba "sexy", kodwa funda "sсuzzy" ("xelela"). Emva koko, ukubizwa kwe "xelela" kwakumiliselwe ngokuqinileyo kulo mgangatho.
Kwisigama se-SCSI, izixhobo ezidityanisiweyo zahlulwe zaba ziindidi ezimbini:
- abaqalisi;
- izixhobo ekujoliswe kuzo.
Umqalisi uthumela umyalelo kwisixhobo ekujoliswe kuso, nto leyo ethumela impendulo kumqalisi. Abaqalisi kunye neethagethi zixhunywe kwibhasi ye-SCSI eqhelekileyo, ene-bandwidth ye-1 MB / s kumgangatho we-SCSI-5.
Itopology "yebhasi eqhelekileyo" esetyenziswayo ibeka inani lezithintelo:
- ekupheleni kwebhasi, izixhobo ezikhethekileyo ziyafuneka - i-terminators;
- I-bandwidth yebhasi kwabelwana ngayo kuzo zonke izixhobo;
- Inani eliphezulu lezixhobo eziqhagamshelwe ngaxeshanye zilinganiselwe.
Izixhobo ebhasi zichongwa ngenombolo eyodwa ebizwa I-ID ye-SCSI ekujoliswe kuyo. Iyunithi nganye ye-SCSI kwisixokelelwano imelwe sisixhobo esinye esinengqiqo, esijongwa linani elilodwa elingaphakathi kwesixhobo esibonakalayo. Inombolo yeYunithi eQinisekayo (LUN).
Imiyalelo kwi-SCSI ithunyelwa ngohlobo iibhloko zenkcazo yomyalelo (Block Descriptor Block, CDB), equka ikhowudi yokusebenza kunye neeparamitha zomyalelo. Umgangatho uchaza imiyalelo engaphezulu kwama-200, yahlulwe ngokweendidi ezine:
- Kunyanzelekile — kufuneka ixhaswe sisixhobo;
- Ukhetho - inokuphunyezwa;
- Umthengisi ngokuthe ngqo - isetyenziswe ngumenzi othile;
- Iphelelwe - imiyalelo ephelelwe lixesha.
Phakathi kwemiyalelo emininzi, mithathu kuphela kubo enyanzelekileyo kwizixhobo:
- IYUNITHI YOVAVANYO ISILUNGILE — ukujonga ukulungela isixhobo;
- CELA INDLELA — icela ikhowudi yempazamo yomyalelo wangaphambili;
- YOPHANDO — cela iimpawu eziphambili zesixhobo.
Emva kokufumana kunye nokucubungula umyalelo, isixhobo esijoliswe kuyo sithumela ikhowudi yesimo kumqalisi, echaza umphumo wokuphunyezwa.
Uphuculo olongezelelweyo lwe-SCSI (i-SCSI-2 kunye ne-Ultra SCSI inkcazo) yandise uluhlu lwemiyalelo esetyenzisiweyo kwaye yandisa inani lezixhobo ezixhunyiwe ukuya kwi-16, kunye nezinga lotshintshiselwano lwedatha kwibhasi ukuya kwi-640 MB / s. Ekubeni i-SCSI i-interface ehambelanayo, ukwandisa ukuphindaphinda kotshintshiselwano lwedatha kwakudityaniswa nokuncipha kobude bobude bekhebula kwaye kukhokelele kukuphazamiseka ekusebenziseni.
Ukuqala ngomgangatho we-Ultra-3 SCSI, inkxaso ye "hot plugging" ibonakala - izixhobo zokudibanisa xa amandla evuliwe.
I-SCSI SSD yokuqala eyaziwayo yayiyi-M-Systems FFD-350, ekhutshwe kwi-1995. Idiski yayinexabiso eliphezulu kwaye yayingasetyenziswanga kakhulu.
Okwangoku, i-SCSI ehambelanayo ayisiyondlela idisk interface edumileyo, kodwa iseti yomyalelo isasetyenziswa ngokusebenzayo kwi-USB kunye ne-SAS yojongano.
ATA/PATA
ujongano I-ATA (I-Advanced Technology Attachment), eyaziwa ngokuba I-POWA (Parallel ATA) yaphuhliswa yiWestern Digital kwi-1986. Igama lokuthengisa lomgangatho we-IDE (Eng. Integrated Drive Electronics - "i-electronics eyakhelwe kwi-drive") igxininise into entsha ebalulekileyo: umlawuli we-drive wahlanganiswa kwi-drive, kwaye kungekhona kwibhodi yokwandisa eyahlukileyo.
Isigqibo sokubeka umlawuli ngaphakathi kwi-drive sisombulule iingxaki ezininzi ngexesha elinye. Okokuqala, umgama osuka kwi-drive ukuya kumlawuli uye wehla, owachaphazela ngokufanelekileyo ukusebenza kwe-drive. Okwesibini, umlawuli owakhelwe ngaphakathi "walolwa" kuphela kuhlobo oluthile lokuqhuba kwaye, ngokufanelekileyo, lwalungabizi.
I-ATA, njenge-SCSI, isebenzisa indlela ye-I / O efanayo, ebonakaliswa kwiintambo ezisetyenzisiweyo. Ukudibanisa iidrives usebenzisa i-interface ye-IDE ifuna iintambo ze-40-core, ezikwabizwa ngokuba ziintambo ezisicaba. Iinkcukacha zamva nje zisebenzisa ii-stubs ze-80-wire, ezingaphezu kwesiqingatha zazo ziyi-loops eziphantsi komhlaba ukunciphisa ukuphazamiseka kwi-frequencies ephezulu.
Kukho iziqhagamshelo ezimbini ukuya kwezine kwintambo ye-ATA, enye yazo iqhagamshelwe kwi-motherboard, kunye nezinye kwiidrives. Xa udibanisa izixhobo ezimbini kwilophu enye, enye yazo kufuneka iqwalaselwe njenge Master, kunye neyesibini njenge ikhoboka. Isixhobo sesithathu sinokudityaniswa kuphela kwimowudi yokufunda kuphela.
Isikhundla se-jumper sinquma indima yesixhobo esithile. Amagama oMphathi kunye neNgqila ngokumalunga nezixhobo azichanekanga ngokupheleleyo, ekubeni ngokumalunga nomlawuli, zonke izixhobo ezixhunyiwe ziyi-Slaves.
I-innovation ekhethekileyo kwi-ATA-3 yimbonakalo Ukuzibeka esweni, Uhlahlelo kunye neTekhnoloji yeNgxelo (SMART). Iinkampani ezintlanu (i-IBM, i-Seagate, i-Quantum, i-Conner, kunye ne-Western Digital) zidibanise imikhosi kunye ne-standard standard drive assessment technology.
Inkxaso ye-slid state drives ikhona ukususela kwinguqulo yesi-1998 yomgangatho, ekhutshwe ngo-33.3. Le nguqulo yomgangatho onikezelweyo wokudluliselwa kwedatha ukuya kuthi ga kwi-XNUMX MB / s.
Umgangatho ubeka phambili iimfuno ezingqongqo kwiintambo ze-ATA:
- iplume kufuneka ibe sicaba;
- ubude uloliwe ubude 18 intshi (45.7 iisentimitha).
Uloliwe omfutshane nobanzi wayengenangxaki kwaye wayephazamisana nokupholisa. Kwaba nzima ngakumbi ukunyusa i-frequency transmission kunye nenguqu nganye elandelayo yomgangatho, kwaye i-ATA-7 yayisombulula ingxaki ngokukhawuleza: i-interface ehambelanayo yatshintshwa yi-serial one. Emva koko, i-ATA yafumana igama elithi Parallel kwaye yaziwa ngokuba yiPATA, kwaye inguqulelo yesixhenxe yomgangatho yafumana igama elahlukileyo - uthotho ATA. Amanani enguqulelo yeSATA aqale kwenye.
SATA
Umgangatho we-Serial ATA (SATA) waziswa ngomhla we-7 kaJanuwari 2003 kwaye walungisa iingxaki zangaphambi kwawo ngolu tshintsho lulandelayo:
- izibuko elinxuseneyo endaweni yalo ngothotho;
- intambo ebanzi engama-80 ethatyathwe ngocingo olu-7;
- I-"common bus" topology iye yathatyathelwa indawo ngoqhagamshelwano oluthi "point-to-point".
Nangona i-SATA 1.0 (SATA / 150, 150 MB / s) yayikhawuleza ngokukhawuleza kune-ATA-6 (UltraDMA / 130, 130 MB / s), ukufudukela kunxibelelwano lwe-serial "kwakumisela umhlaba" wesantya.
Imigca yemiqondiso elishumi elinesithandathu yokuhanjiswa kwedatha kwi-ATA yatshintshwa ngamabini amabini ajijekileyo: enye yokuhanjiswa, okwesibini ukufumana. Izixhumi ze-SATA zenzelwe ukuba zixhathise ngakumbi kwii-multiple reconnections, kwaye inkcazo ye-SATA 1.0 yenze iplagi eshushu inokwenzeka.
Ezinye izikhonkwane kwiidrive zimfutshane kunazo zonke ezinye. Oku kwenziwa ukuxhasa "hot swap" (Hot Swap). Ngexesha lenkqubo yokutshintshwa, isixhobo "silahlekelwa" kwaye "sifumana" imigca ngokulandelelana kwangaphambili.
Kwisithuba esingaphezu konyaka kamva, ngoAprili 2004, inguqulelo yesibini yenkcazo yeSATA yakhululwa. Ukongeza ukukhawuleza ukuya kwi-3 Gb / s, i-SATA 2.0 yazisa iteknoloji Native Command Queuing (NCQ). Izixhobo ezinenkxaso ye-NCQ ziyakwazi ukulungelelanisa ngokuzimeleyo umyalelo wokuphunyezwa kwemiyalelo engenayo ukuphumeza ukusebenza okuphezulu.
Kwiminyaka emithathu elandelayo, iQela eliSebenzayo le-SATA lasebenza ekuphuculeni ukucaciswa okukhoyo, kwaye inguqulo ye-2.6 yazisa i-compact Slimline kunye nezixhumi ze-SATA ezincinci (uSATA). Ezi ziqhagamshelo ziyinguqulelo encinci yesiqhagamshelo se-SATA sokuqala kwaye zenzelwe iidrives ezibonakalayo kunye needrive ezincinci kwiilaptops.
Ngelixa i-SATA yesizukulwana sesibini sine-bandwidth eyaneleyo yee-HDDs, ii-SSD zazifuna ngaphezulu. NgoMeyi ka-2009, inguqulelo yesithathu yenkcazo ye-SATA yakhululwa ngokunyuka kwe-bandwidth ukuya kwi-6 Gb / s.
Ingqwalasela ngokukodwa ihlawulwe kwiidrive zesimo esiqinileyo kwi-SATA 3.1 edition. I-Mini-SATA (mSATA) isidibanisi iye yavela, eyilelwe ukudibanisa i-slid-state drives kwii-laptops. Ngokungafaniyo ne-Slimline kunye ne-SATA, isinxibelelanisi esitsha sasijongeka njengePCIe Mini, nangona yayingahambelani ngombane nePCIe. Ukongeza kwisinxibelelanisi esitsha, i-SATA 3.1 yaqhayisa ngokukwazi ukufola imiyalelo ye-TRIM ngemiyalelo yokufunda nokubhala.
Umyalelo we-TRIM wazisa i-SSD yeebhloko zedatha ezingathwali umthwalo. Ngaphambi kwe-SATA 3.1, lo myalelo unokugungxula iicache kwaye unqumamise imisebenzi ye-I/O, ulandelwa ngumyalelo we-TRIM. Le ndlela ithoba ukusebenza kwediski ngexesha lokucima imisebenzi.
Inkcazo ye-SATA ayizange igcine ukukhula okukhawulezayo kwizantya zokufikelela kwi-SSD, ekhokelela kwi-compromise kwi-2013 ebizwa ngokuba yi-SATA Express kumgangatho we-SATA 3.2. Esikhundleni sokuphinda kabini i-bandwidth ye-SATA kwakhona, abaphuhlisi basebenzise ibhasi ye-PCIe esetyenziswa ngokubanzi, isantya sayo sidlula i-6 Gb / s. Ukuqhuba ngenkxaso ye-SATA Express baye bafumana into yabo yefom ebizwa ngokuba yi-M.2.
SAS
Umgangatho we-SCSI, "ukukhuphisana" kunye ne-ATA, awuzange ume ngxi kwaye nje unyaka emva kokubonakala kwe-Serial ATA, ngo-2004, yaphinda yazalwa ibe yi-serial interface. Igama lojongano olutsha ngu Uthotho oluncamatheleyo kwi-SCSI (SEEDGE).
Nangona i-SAS yazuza njengelifa iseti yomyalelo we-SCSI, utshintsho lwalubalulekile:
- ujongano lweserial;
- 29-intambo yocingo kunye nombane;
- uqhagamshelo lwamanqaku
Isigama se-SCSI siye safunyanwa njengelifa. Umlawuli usabizwa ngokuba ngumqalisi, kwaye izixhobo ezixhunyiwe zibizwa ngokuba yithagethi. Zonke izixhobo ekujoliswe kuzo kunye nomqalisi benza i-domain ye-SAS. Kwi-SAS, i-bandwidth yoqhagamshelo ayixhomekeke kwinani lezixhobo kwi-domain, ekubeni isixhobo ngasinye sisebenzisa itshaneli yaso ezinikeleyo.
Inani eliphezulu lezixhobo eziqhagamshelwe ngaxeshanye kwi-domain ye-SAS, ngokwenkcazo, idlula i-16 lamawaka, kwaye endaweni ye-ID ye-SCSI, isazisi sisetyenziselwa ukujongana. Igama Lehlabathi Lonke (WWN).
I-WWN sisichongi esisodwa se-16 bytes ubude, efana nedilesi ye-MAC yezixhobo ze-SAS.
Ngaphandle kokufana phakathi kwe-SAS kunye nezixhumi ze-SATA, le migangatho ayihambelani ngokupheleleyo. Nangona kunjalo, idrayivu ye-SATA inokuqhagamshelwa kwikhonkco le-SAS, kodwa hayi ngokuphambeneyo. Ukuhambelana phakathi kwe-SATA drives kunye ne-SAS domain kuqinisekiswa ngokusebenzisa iProtocol ye-SATA Tunneling (STP).
Inguqu yokuqala yomgangatho we-SAS-1 ine-bandwidth ye-3 Gb / s, kwaye eyona mihla, i-SAS-4, iphucule eli nani ngamaxesha angama-7: 22,5 Gb / s.
PCI
I-Peripheral Component Interconnect Express (PCI Express, PCIe) yi-serial interface yokudluliselwa kwedatha, evele kwi-2002. Uphuhliso lwaqalwa yi-Intel, kwaye emva koko lwatshintshelwa kumbutho okhethekileyo - iQela leNzala eliKhethekileyo lePCI.
I-serial PCIe interface yayingekho ngaphandle kwaye yaba kukuqhubeka okunengqiqo kwe-PCI ehambelanayo, eyilelwe ukudibanisa amakhadi okwandisa.
I-PCI Express yahluke kakhulu kwi-SATA kunye ne-SAS. I-PCIe interface inenani eliguquguqukayo leendlela. Inani lemigca lilingana namagunya amabini kunye noluhlu ukusuka ku-1 ukuya kwi-16.
Igama elithi "umzila" kwi-PCIe alibhekiseli kwindlela yomqondiso othile, kodwa kwikhonkco lonxibelelwano eliphindwe kabini elibandakanya ezi ndlela zilandelayo:
- yamkela+ kwaye wamkele-;
- ugqithiso+ kunye nogqithiso-;
- iingcingo zomhlaba ezine.
Inani lemizila ye-PCIe ichaphazela ngokuthe ngqo ubuninzi be-bandwidth yoqhagamshelwano. Umgangatho wangoku we-PCI Express 4.0 ikuvumela ukuba ufezekise i-1.9 GB / s kumgca omnye, kunye ne-31.5 GB / s xa usebenzisa i-16 imigca.
I "appetites" ye-slid-state drives ikhula ngokukhawuleza. Zombini i-SATA kunye ne-SAS azikwazanga ukunyusa i-bandwidth yazo ukuze zihambisane ne-SSD, nto leyo ekhokelele ekufakweni kwee-SSD ezixhunyiwe kwi-PCIe.
Nangona amakhadi e-PCIe Add-In ekrwelwe, i-PCIe iyatshintshatshintsha. Izikhonkwane ezimfutshane PRSNT (IsiNgesi ekhoyo - ekhoyo) qinisekisa ukuba ikhadi lifakwe ngokupheleleyo kwindawo yokubeka.
Iidrive zombuso oqinileyo eziqhagamshelwe ngePCIe zilawulwa ngumgangatho owahlukileyo INkcazelo yesiLawuli soMamkeli weMemori engaguquguqukiyo kwaye iqulethwe kwiinkalo ezahlukeneyo, kodwa siza kuthetha ngazo kwinxalenye elandelayo.
IiDrives ezikude
Xa usenza iindawo zokugcina idatha enkulu, bekukho imfuneko yeeprothokholi ezikuvumela ukuba uqhagamshele iidrive ezibekwe ngaphandle kweseva. Isisombululo sokuqala kule ndawo sasi I-SCSI ye-Intanethi (iSCSI), ephuhliswe yi-IBM kunye neCisco kwi-1998.
Ingcamango emva kwe-iSCSI protocol ilula: imiyalelo ye-SCSI "isongiwe" kwiipakethi ze-TCP/IP kwaye ithunyelwe kuthungelwano. Ngaphandle koqhagamshelo olukude, inika inkohliso kubathengi ukuba i-drive iqhagamshelwe ekuhlaleni. Inethiwekhi yendawo yokugcina esekelwe kwi-iSCSI (SAN) inokwakhiwa kwiziseko zoncedo zothungelwano ezikhoyo. Ukusetyenziswa kwe-iSCSI kunciphisa kakhulu ixabiso lokuququzelela i-SAN.
I-iSCSI inokhetho lwe "premium" - Iprotocol yeFiber Channel (FCP). I-SAN isebenzisa i-FCP yakhelwe kwiintambo zonxibelelwano ezizinikeleyo zefiber-optic. Le ndlela idinga izixhobo ezongezelelweyo zenethiwekhi ye-optical, kodwa izinzile kwaye iphezulu.
Zininzi iiprothokholi zokuthumela imiyalelo yeSCSI kuthungelwano lwekhompyuter. Nangona kunjalo, kukho umgangatho omnye kuphela osombulula ingxaki eyahlukileyo kwaye ikuvumela ukuba uthumele iipakethi ze-IP ngaphezulu kwebhasi ye-SCSI - .
Iiprothokholi ezininzi ze-SAN zisebenzisa umyalelo we-SCSI omiselweyo ukulawula iidrive, kodwa kukho iminxa, efana nelula ATA ngaphezulu kwe-Ethernet (AOE). Iprotocol ye-AoE ithumela imiyalelo ye-ATA kwiipakethi ze-Ethernet, kodwa iidrive zivela njenge-SCSI kwinkqubo.
Ngokufika kwe-NVM Express drives, iiprotocol ze-iSCSI kunye ne-FCP azisahlangabezani neemfuno ezikhula ngokukhawuleza zee-SSD. Izisombululo ezibini ziye zavela:
- ukususwa kwebhasi yePCI Express ngaphandle komncedisi;
- ukwenziwa kweNVMe ngaphezulu kweFabrics protocol.
Ukususa ibhasi yePCIe kudala ihardware yokutshintsha okuntsonkothileyo kodwa ayitshintshi iprotocol.
Iprotocol ye-NVMe phezu kweFabrics iye yaba yenye ilungileyo kwi-iSCSI kunye neFCP. I-NVMe-oF isebenzisa ikhonkco lefiber optic kunye neseti yomyalelo weNVM Express.
I-DDR-T
Imigangatho ye-iSCSI kunye ne-NVMe-oF ixazulula ingxaki yokudibanisa i-drives ekude njengeendawo zendawo, ngelixa i-Intel yahamba ngenye indlela kwaye yazisa i-drive yendawo ngokusondeleyo kwiprosesa. Ukhetho lwawela kwii-slots ze-DIMM apho i-RAM ixhunyiwe. I-bandwidth ephezulu ye-DDR4 yi-25 GB / s, ekhawuleza kakhulu kunebhasi ye-PCIe. Le yindlela eyazalwa ngayo i-Intel® Optane™ DC Memory Memory SSD.
Iprothokholi yaqanjwa ukudibanisa idrayivu kwiindawo zokubeka ze-DIMM I-DDR-T, ngokomzimba nangombane iyahambelana ne-DDR4, kodwa ifuna umlawuli okhethekileyo obona umehluko phakathi kwebha yememori kunye ne-drive. Isantya sokufikelela kwi-drive singaphantsi kwe-RAM, kodwa ngaphezu kwe-NVMe.
I-DDR-T ifumaneka kuphela ngeeprosesa ze-Intel® Cascade Lake okanye kamva.
isiphelo
Phantse zonke ii-interfaces zihambe umgama omde ukusuka kwi-serial ukuya kwi-parallel data transmission. Izantya ze-SSD zinyuka, izolo ii-SSD zazinomdla, kwaye namhlanje i-NVMe ayiseyiyo into emangalisayo.
Kwilabhoratri yethu unokuvavanya i-SSD kunye ne-NVMe uqhuba ngokwakho.
Ngabasebenzisi ababhalisiweyo kuphela abanokuthatha inxaxheba kuphando. , ndiyacela.
Ngaba ii-NVMe drives ziya kuthatha indawo yee-SSD zakudala kungekudala?
