Lub lim tiam dhau los Western Digital nyob rau hauv teb rau kev tshwm sim ntawm undocumented siv SMR (Shingled Magnetic Media Recording) technology nyob rau hauv WD Red NAS tsav nrog muaj peev xwm ntawm 2 thiab 6 TB. Toshiba thiab Seagate Blocks & Files cov peev txheej uas qee qhov ntawm lawv cov tsav tsheb kuj siv tsis muaj ntaub ntawv SMR thev naus laus zis. Kuv xav tias nws yog lub sijhawm rau cov neeg muag khoom PC los ntxuav cov khoom.
SMR pobzeb sib nqus cov ntaubntawv povthawj siv txoj kev ua rau nws muaj peev xwm ua kom lub peev xwm cia li 15-20%. Txawm li cas los xij, thev naus laus zis muaj qhov tsis zoo tseem ceeb, qhov tseem ceeb ntawm qhov uas yog qhov txo qis ntawm kev rov sau cov ntaub ntawv, uas tuaj yeem yog qhov tseem ceeb heev thaum siv hauv PC.
Yog li ntawd, cov tuam txhab desktop thiab laptop yuav tsum qhia meej meej hauv cov ntaub ntawv kev tshaj lij thiab cov khoom lag luam uas lawv lub tshuab siv tsav nrog SMR thev naus laus zis. Qhov no yuav tiv thaiv qee qhov WD Red NAS tsav los ntawm kev tshwm sim hauv cov neeg siv khoom PCs.
Ib qhov chaw lag luam loj, uas xav tsis qhia npe, hais rau Blocks & Files: "Nws tsis yog qhov xav tsis thoob tias WD thiab Seagate tau muab SMR desktop hard drives rau OEMs - tom qab tag nrho, lawv pheej yig dua rau ib lub peev xwm. Thiab hmoov tsis, nws tsis yog qhov xav tsis thoob tias cov tuam txhab lag luam desktop zoo li Dell thiab HP siv lawv hauv lawv lub tshuab yam tsis tau qhia rau lawv cov neeg siv khoom thiab cov neeg siv khoom kawg (thiab / lossis cov lag luam PC cov neeg yuav khoom, feem ntau yog cov neeg yuav khoom) ... Kuv xav tias qhov teeb meem twb kis thoob plaws hauv cov khoom siv. saw thiab tsis yog tsuas yog txwv rau hard drive manufacturers. "
WD siv SMR nyob rau hauv nws cov Red series drives nrog lub peev xwm ntawm 1, 2, 3, 4 thiab 6 TB, thiab cov ntaub ntawv CMR zoo nyob rau hauv 8, 10, 12 thiab 14 TB drives ntawm tib tsev neeg. Ntawd yog, peb tab tom tham txog kev faib ib tsev neeg ntawm cov khoom lag luam rau hauv ob feem, txhua tus siv cov cuab yeej sib txawv disk kaw. Ntxiv mus, SMR yog siv los txo tus nqi ntawm cov kev daws teeb meem pheej yig dua.
WD hauv nws cov lus tau sau tseg tias thaum kuaj WD Red drives, nws tsis pom muaj teeb meem nrog RAID kev tsim kho vim yog SMR thev naus laus zis. Txawm li cas los xij, cov neeg siv ntawm Reddit, Synology thiab smartmontools forums tau pom cov teeb meem: piv txwv li, nrog ZFS RAID thiab FreeNAS txuas ntxiv.
Alan Brown, tus thawj coj hauv network ntawm UCL uas pib tshaj tawm qhov teeb meem SMR, hais tias: "Cov tsav tsheb no tsis haum rau lub hom phiaj no (siv hauv RAID rov tsim kho). Vim hais tias nyob rau hauv cov ntaub ntawv tshwj xeeb no lawv ua rau ib tug kuj provable thiab rov qab teeb meem uas ua rau muaj teeb meem loj. SMR drives muag rau NAS thiab RAID muaj xws li qhov tsis txaus ntseeg thiab kev hloov pauv uas lawv tsuas yog siv tsis tau.
Txawm tias cov neeg siv Seagate drives nrog SMR tau tshaj tawm qee lub sijhawm 10-thib ob ncua sijhawm hauv cov ntaub ntawv kaw tseg, thiab cov neeg uas pib muaj kev ua tau zoo nrog SMR drive arrays tau lees paub tias cov txheej txheem thaub qab tsav rov tsim ua pov thawj yog qhov teeb meem tseem ceeb uas lawv tsis lees txais mus txog thaum peb tau sim siv nws hauv kev xyaum.
