Ngasekupheleni kwesonto eledlule i-Western Digital ekuphenduleni ukwambulwa kokusetshenziswa okungagunyaziwe kobuchwepheshe be-SMR (Shingled Magnetic Media Recording) kumadrayivu e-WD Red NAS anamandla angu-2 TB kanye ne-6 TB. I-Toshiba ne-Seagate Isisetshenziswa se-Blocks & Files amanye amadrayivu awo aphinde asebenzise ubuchwepheshe be-SMR obungabhaliwe. Ngicabanga ukuthi sekuyisikhathi sokuthi abathengisi be-PC bahlanze izinto.
Indlela yokurekhoda enozibuthe enethayela ye-SMR yenza kube nokwenzeka ukukhulisa umthamo wokugcina ngo-15-20%. Kodwa-ke, ubuchwepheshe bunezithiyo ezibalulekile, ukhiye wawo ukwehla kwejubane lokubhala kabusha idatha, okungaba bucayi kakhulu uma kusetshenziswe ku-PC.
Ngakho-ke, abakhiqizi bedeskithophu kanye namalaptop kumele bakhombise ngokusobala emibhalweni yobuchwepheshe kanye nezinto zokumaketha ukuthi amasistimu abo asebenzisa amadrayivu anobuchwepheshe be-SMR. Lokhu kuzovimbela amanye amadrayivu e-WD Red NAS ukuthi angenzeki kuma-PC omthengi.
Umthombo wezimboni eziphezulu, obufisa ukungadalulwa igama, utshele i-Blocks & Files: “Akumangazi ngempela ukuthi i-WD ne-Seagate bezinikeza ama-hard drive edeskithophu ye-SMR kuma-OEMs—phela ashibhile ngomthamo ngamunye. Futhi ngeshwa, akumangazi ukuthi abakhiqizi bedeskithophu abafana no-Dell no-HP bawasebenzise emishinini yabo ngaphandle kokutshela amakhasimende abo nabasebenzisi bokugcina (kanye/noma abathengi be-PC yebhizinisi, ngokuvamile ababenzeli bokuthenga)... Ngicabanga ukuthi inkinga isivele isabalele kukho konke chain futhi ayigcini nje kuphela kubakhiqizi be-hard drive. "
I-WD isebenzisa i-SMR kumadrayivu ayo ochungechunge lwe-1, 2, 3, 4, kanye ne-6 TB Red, kanye ne-CMR evamile kumadrayivu ayo angu-8, 10, 12, kanye ne-14 TB omndeni ofanayo. Okusho ukuthi, sikhuluma ngokuhlukanisa umndeni owodwa wemikhiqizo ibe izingxenye ezimbili, ngayinye esebenzisa ubuchwepheshe obuhlukene bokuqopha idiski. Ngaphezu kwalokho, i-SMR isetshenziselwa ukwehlisa izindleko zezixazululo ezithengekayo.
I-WD esitatimendeni sayo iphawule ukuthi lapho ihlola amadrayivu e-WD Red, ayizange ithole izinkinga ngokwakhiwa kabusha kwe-RAID ngenxa yobuchwepheshe be-SMR. Kodwa-ke, abasebenzisi bezinkundla zeReddit, Synology kanye ne-smartmontools bathole izinkinga: isibonelo, ngezandiso ze-ZFS RAID kanye ne-FreeNAS.
U-Alan Brown, umphathi wenethiwekhi e-UCL oqale wabika ngodaba lwe-SMR, uthe: “Lawa madrayivu awafanele le njongo (sebenzisa ekwakhiweni kabusha kwe-RAID). Ngoba kuleli cala elithile abangela inkinga kuqhathaniswa provable futhi repeatable okuholela amaphutha angathi sína. Amadrayivu e-SMR athengiswe i-NAS kanye ne-RAID anomphumela ongemuhle futhi oguquguqukayo kangangokuthi awasebenziseki.
Ngisho nabantu abasebenzisa amadrayivu e-Seagate ane-SMR baye babika ukumiswa okwesikhashana kwemizuzwana eyi-10 ekurekhodweni, futhi labo abaqale basebenza kahle nge-SMR drive arrays bakuqinisekisile ukuthi inqubo yokwakha kabusha idrayivu eyisipele ibonakale iyinkinga enkulu abangazange bayamukele kuze kube yilapho. sizamile ukukusebenzisa ngokwenza.”
