Ama-hard drive e-SMR (afakwe amathayela) ngaphandle kokukhombisa ubukhona be-SMR angena eziteshini zokuthengisa

Bobathathu abakhiqizi baqale ukuthengisa ezincane, kusukela ku-2TB HDD Amadiski e-SMR (afakwe amathayela)ngaphandle kokuyicacisa emibhalweni: WD, Seagate, Toshiba

Ku-inthanethi yolimi lwesiNgisi nabezindaba, izenzo ezinjalo ziyagxekwa futhi, ngicabanga, kufanele. E-Russia, insiza ye-THG yaphawulwa ngendatshana I-Western Digital isebenzisa i-DM-SMR, yenza amadrayivu e-WD Red afanele i-NAS ne-RAID. Lesi sihloko, ngokubona kwami, singamanga angenamahloni, kusukela esihlokweni kuya esiphethweni: "Siyabonga kubuchwepheshe bokurekhoda be-DM-SMR, i-Western Digital yenze ama-hard drive ayo e-WD Red afanele i-NAS ne-RAID." Kuyathakazelisa ukuthi kunguqulo yesiNgisi yalesi sihloko I-Western Digital Fesses Up: Amanye ama-HDD Abomvu Asebenzisa I-Slow SMR Tech Ngaphandle Kokudalula
akukho ukusikisela kokuhlanekezelwa kwamaqiniso okunjalo

Futhi embhalweni othi thg.ru ubhekisa ku-Alan Brown,

U-Alan Brown, umqondisi wenethiwekhi e-UCL Mullard Space Science Laboratory, uthole indlela yokuphuma kulesi simo. Uthole ukuthi ukulahlwa kwe-RAID, okwenziwa lapho wengeza idrayivu entsha ohlwini olukhona lwe-RAID bese uyibhala ngaphezulu ukuze ubhalansise ukufinyelela, kubangele ukuthi uhlelo lukhiphe ama-WD Red HDD amasha angalawuleki.

Akucaci kahle ukuthi kusho ukuthini ngempela ukuthi "uhlelo lususa ama-WD Red HDD amasha ngaphansi kwawo." - kodwa ngokwencazelo yesiphakamiso, lesi yisixazululo.

Ngesikhathi esifanayo Empeleni u-Alan wabhala ngesihloko - kodwa okuphambene kakhulu

Idrayivu ye-WD40EFAX engiyigcwalise ngoziro inesilinganiso esingu-40MB/s, kodwa yaqala ku-120MB/s.

Endabeni ye-ZFS, isixazululi akusona ukuskena kwezinga lokuvala kuya ekupheleni, kodwa sigxumela kuyo yonke idiski njengoba ifayela ngalinye libuyiselwa ekulinganeni. Lokhu kubonakala kubangela enye inkinga ku-WD40EFAX, lapho isicelo sokuhlola umkhakha ongakabhalelwa ukuthi sibangele ukuthi idrayivu ingene ngaphakathi iphutha elithi "I-ID Yomkhakha Ayitholakali (IDNF)" bese kuphonsa iphutha le-Hardware I/O kusuka. isikhombimsebenzisi kusistimu yokusingatha.

Izilawuli ze-RAID (izingxenyekazi zekhompyutha noma isofthiwe, i-RAID5/6 noma i-ZFS) zizonquma ngokunengqondo ukuthi idrayivu imbi ngemva kwezimbalwa zazo futhi ziyikhiphe ohlwini uma ingakenziwa ngemva kokuphela kwesikhathi.

Lokhu ngokuqinisekile kufana nalokho engikuqaphelile - umamukeli uhamba cishe ku-100MB / s cishe imizuzu engama-40, emva kwalokho ushayela "Fa" futhi ufe ngokuphindaphindiwe uma ngizama ukuqalisa kabusha umamukeli, noma kunjalo, uma ngiyishiya - ngemva kwehora noma ngaphezulu. , basebenza eminye imizuzu engu-40 ngaphambi kokuwa.

Kunzima ukucabanga ukuthi yini ngempela eyenza i-thg.ru yenze lokhu. Umuntu angaqagela ukuthi ngabe lokhu bekungenxa yengcindezi yabakhangisi. Kunoma ikuphi, isimo lapho amadrayivu adumile ahloselwe ngqo i-NAS ashintshwa buthule angafaneleki kakhulu ngentengo efanayo futhi ngaphandle kokushintsha izicaciso kufanele ukunakwa.

Engqungqutheleni Kube nokukhulunywa ngenkinga kuwebhusayithi ye-WD. Ingqikithi iyafana

Ngisanda kuthenga ama-3 WD RED ukuze ngibuyisele amadrayivu aguga ohlwini lwe-ZFS

BONKE ABATHATHU bayehluleka ngesikhathi sokuhlangana kabusha namaphutha e-IDNF (i-ID yomkhakha ayitholakali):

Ngokuqonda kwami, inkinga iku
I-WD RED - I-WD Red EFAX amadrayivu e-SMR futhi anenqolobane engu-256 MB. Amadrayivu e-EFRX - awasebenzisi i-SMR (lawa amadrayivu avamile e-CMR) futhi anenqolobane engu-64 MB
I-Toshiba inamamodeli amaningana imininingwane eyengeziwe lapha
I-Seagate inochungechunge oluningana - imininingwane eyengeziwe lapha
