Engqungqutheleni yokubika yekota kaSeagate, inhloko yenkampani ivumile ukuthi ukulethwa kwama-hard drive e-TB ayi-16 kwaqala ekupheleni kukaMashi, manje asehlolwa ozakwethu namakhasimende alo mkhiqizi. Amashayela asebenzisa ubuchwepheshe be-laser-assisted magnetic wafer heat (HAMR), njengoba umqondisi omkhulu we-Seagate ephawula, abonwa kahle ngamakhasimende: “Asebenza nje.” Kepha eminyakeni embalwa edlule bekukhulunywa ngabo bonke ubuchwepheshe be-HAMR mayelana nokuthembeka kwayo okuphezulu okunganele, futhi izimbangi ze-Seagate azizange zisheshe ukuzisebenzisa. Nokho, kufanele kucatshangelwe ukuthi i-Seagate ayikakakulungeli ukuhlinzeka ngokuhweba ngama-hard drive anjalo, futhi ukusetshenziswa kwezohwebo kobuchwepheshe be-HAMR kuzoqala kuphela ngemva kokukhululwa kwamadrayivu angama-20 e-TB.
Uma ubheka, u-Toshiba isikhathi eside ugxile ekwandiseni inani lamapuleti kazibuthe ku-hard drive case, futhi akazange asheshe ukwethula izinto ezintsha ezifana nesakhiwo esifanayo "se-tile" (SMR). Ngenxa yalokho, ifinyelele embundwini wamandla we-16 TB ngesakhiwo sakudala samapuleti kazibuthe futhi kuphela lapho ifinyelela umkhawulo we-TB we-18 lapho izoqala ukusebenzisa i-SMR, nakuba ivumela futhi inhlanganisela yamapuleti avamile nobuchwepheshe be-MAMR, okubandakanya ukuthonya abezindaba usebenzisa ama-microwaves. Kodwa ku-Toshiba, ukubeka izicwecwe kazibuthe eziyisishiyagalolunye endaweni eyodwa engu-3,5″ yefomu yesici kuyisiteji esiphumelele, futhi inkampani icabanga ukudala amadrayivu anezicwecwe eziyishumi kazibuthe.
Intshisekelo kaToshiba yokwandisa ukuminyana kwezicwecwe zikazibuthe yaze yasebenza njengento ehloselwe ukuhlanjalazwa yi-Western Digital Corporation, abameleli bayo engqungqutheleni yokubika yekota bathi ama-hard drive ayo ayi-16 TB amapuleti kazibuthe ayisishiyagalombili anobuchwepheshe be-MAMR azoba ishibhile ukukhiqiza kunezimbangi. imikhiqizo. I-WDC izoba yingcweti endleleni “yethayela” lapho ikhulula amadrayivu e-TB ayi-18, azokhishwa ngaphambi kokuphela kwalo nyaka. Lapho ikhiqiza amadrayivu anomthamo ongaphezu kuka-20 TB eminyakeni eyishumi ezayo, i-WDC ngeke isebenzise ubuchwepheshe be-MAMR kuphela, kodwa futhi namayunithi amakhanda amabili azimele (ama-actuator).
Isixazululo sakamuva siphinde sisetshenziswe yi-Seagate, futhi ekuphathweni kwengqungquthela yekota yachaza ukuthi ukushintshela kumabhulokhi amabili ekhanda kunganikeza ukwanda okukhulu kwesivinini sokudlulisa idatha, okudingekayo, isibonelo, ngomsebenzi onzima ngevidiyo. Ngo-April inkampani inguqulo yangaphambi kokukhiqizwa kwe-hard drive ye-16 TB enobuchwepheshe be-HAMR; ukulethwa kwamasampula amadrayivu anjalo kwaqala ekupheleni kukaMashi, kodwa ngeke kuqale ukukhiqizwa. Ngonyaka, ngokusho kwabamele i-Seagate, amamodeli we-TB ayi-16 azoba imithombo eyinhloko yenkampani yemali engenayo engxenyeni yeseva. Izinguqulo ze-serial zemikhiqizo yale volumu zizohlanganisa ukuqoshwa “kwe-perpendicular” ne-TDMR kumapuleti ayisishiyagalolunye; i-Seagate izoshintshela ekurekhodeni “okunamathayili” kuphela lapho ikhiqiza amadrayivu e-TB ayi-18, kodwa izokwenza ngaphandle kwamaqhinga afana ne-HAMR.
Ngonyaka wekhalenda ka-2020, i-Seagate izokwethula ama-hard drive angu-20 TB ngobuchwepheshe be-HAMR. Ngokuhamba kwesikhathi, kuzokwenza kube nokwenzeka ukudala ama-hard drive anamandla angaphezu kwama-40 TB, kodwa bonke abaqhudelana ne-Seagate bathembisa ngento efanayo, besebenzisa isethi yobuchwepheshe ehluke kancane, ngakho-ke umzabalazo emakethe ye-drive uthembisa ukuthi unzima kakhulu. .
