Ngentwasahlobo yowe-1987, uguquko lwamehlo lwaye lwaba yinto yokwenene. wayivumela ukuba igqwese oyena ukhuphisana naye usondeleyo, iWinchester, ngokuphindwe kalishumi (yiloo nto abayibhalayo, ngonobumba omkhulu). I-brainiacs ye-Optimem kunye ne-Verbatim yayilungiselela i-prototypes ye-optical drives ebhalwe ngokutsha, kwaye iingcali kunye nabahlalutyi benza izicwangciso zexesha elide. Enye yeentsika zehlabathi zenzululwazi, esaphila nanamhlanje, iSayensi edumileyo kwinqaku elithi βErasable Optical disksβ yashiya ithuba lokurekhoda ngemagnethi. Olu papasho lwaphela ngoqikelelo lukaNjingalwazi uBill Meiklejohn, ngelo xesha wayesele engumqeshwa Jikelele woMbane owayechithe iminyaka engama-35 efunda ngemagnethi. Ngokombono wakhe, izixhobo zokurekhoda zamagnetic zazineminyaka elishumi yokuphila, zingabikho.
I-Verbatim namhlanje igxile ekukhanyeni kwe-LED kunye ne-3D yoshicilelo lwemathiriyeli ekrwada. Abahlalutyi abaninzi abasekho kuludwe lwabaphilayo. Kwaye imarike ye-HDD inempilo, kwaye imfuno yokugcina iphula iirekhodi. Umthamo opheleleyo we-magnetic hard drives ezithunyelwe kunyaka ophelileyo udlule i-exabytes ye-800, ephindwe kathathu kune-Notre Dame de Paris eyaziwayo.
Kwaye iidiski zemagneti ziyahamba. Bahamba bayothatha yonke idata endlini. Ayigcini iifoto zaselwandle okanye kwithala leencwadi lenzululwazi. Ayaziwa apho aya khona. Baya kuba kwindawo ephakamileyo ezintabeni kungekhona kwindawo yethu. Emafini, ukuchaneka ngakumbi.
Abathengisi akusafuneki ukuba bathengise ii-HDD kwimarike yabathengi. Nangona i-Western Digital, endaweni ye-flagship ye-WD Gold brand, ngoku ithengisa into ehlala iphantsi kwelebula - i-Ultrastar, imveliso ethembekileyo kunye nekhwalithi ephezulu. Isixhobo seseva.
Ngendlela, kungenxa yokufakelwa kwegazi elitsha elivela kwi-HGST ukuba icandelo lomncedisi we-WD libonise amandla alo kunye . Emva koko, abafazi basekhaya ngoku baphatha ii-SSD. Nangona kunjalo, uphuhliso lwe-slid-state lwe-WD kunye ne-Seagate aluphumelelanga. Emva koko kwafuneka ndiyokuthengiselana emarikeni ukuze ndihlale khona. I-Seagate yathatha abalawuli beSandForce, iNtshona yavuna isivuno sonke ngokuthenga i-SunDisk.
Ngoku i-wave yentengiso isebenzela ii-SSD. Kodwa iibrendi ezingenangqondo zexesha elidlulileyo, zixhaphaza isiseko sezinto zamanzi (iBarracuda esuka eSeagate, nangaphambili iPirahna esuka kwi-WD), iya kuba zizilwanyana kuphela kwimyuziyam yenguqu yobugcisa.
Kuthekani ngeHDD? Ngaba siya kulibala ngokukhawuleza ngabo, kanye njengokuba silibale ngeteyiphu yemagnethi? Kungakhathaliseki ukuba kunjani: sisindile kwizibhengezo ze-100TB zokuqhuba, siya kusinda kwakhona ukurekhoda kwethayile. Awuzoyidinga ekhaya kakade.
