Kwiinyanga ezimbalwa ezidlulileyo ndikushiyele inqaku malunga nendlela yokulinganisa isantya se-HDD nge mzantsiEwe, ngeli xesha ndiza kukubonisa indlela yokwenza okufanayo: dd

I-wd-scorpio-emnyama

Linganisa isantya sokufunda nokubhala kwe-HDD nge-dd

Umyalelo omnye wanele ukwazi oku, lo myalelo ulandelayo:

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

Eyona nto iya kuyenza kukudala kwaye ubhale idatha yeerandoms kwifayile (ebizwa ngokuba luvavanyo), ubunzima bokugqibela buya kuba yi-1024MB, oko kukuthi, i-1GB, kwaye izakusixelela ntonikwaye yintoni ebaluleke kuthi) iya kuba sisantya esigcwalisa ngayo i-1024MB kunye nexesha elithathiweyo.

Nantsi umfanekiso wesiphelo sendlela emva kokwenza lo myalelo:

Isantya se-dd-hdd

Njengoko ubona, kuthathe imizuzwana eli-9 ukugcwalisa loo GB, oko kuthetha ukuba isantya sasiyi-119 MB / s ... asibi 😉

Ndazi njani ukuba i-HDD yam icotha?

Ukwazi ukuba i-hard drive yakho iyacotha kufuneka wazi nje ukuba nasiphi na isantya esingaphezulu kwe-50 MB / s samkelekile (ndiyaphinda, ndiyamkeleka, andikhawulezisi). Kwimeko apho i-hard drive yakho ingalingani okanye ufuna enye okanye i-SSD ekhawulezayo, ndincoma ukuba ujonge kwiivenkile ezikhethekileyo apho baya kukucebisa xa kuziwa thenga ii-hard drive kwaye becela, baya kuncoma i-hard drive oyifunayo ngokwenene ngokusekelwe kuhlahlo lwabiwo-mali okanye iimfuno. Kwimeko yam ikhompyuter ye-desktop ene-HDD yesiqhelo indinike i-70 MB / s. Ewe kunjalo, ukuba yi-SSD okanye i-RAID kwaye isantya "esamkelekileyo" asifani ????
Ukuba ufuna i-hard drive yeserver iya kuhlala ingcono ukusebenzisa i-SSD, ngaphandle kokuba kucacile ukuba iserver ifuna ubuninzi bokugcina ukuze ube une-HDD ecothayo kunye nomthamo omkhulu okanye wenza utyalomali ukuthenga ii-SSD ezinzima kunye nokwenza ugqogqo.

Isiphelo!

Ngokusisiseko yile, ndiyathemba ukuba iluncedo kuwe.

      Ii-HDD ezingama-250GB ze-IDE zikhona kwaye ziyathengiswa, jonga apha: http://www.ebay.com/bhp/250gb-ide-hard-drive

      Enye into eyahlukileyo iya kuba nakho ukuthenga kwi-eBay, ukuhanjiswa kwilizwe lakho, njl.

      Malunga nenye into ondibuze yona ... Ndiyathanda ukuthi kwikhompyuter akukho nto ingenakwenzeka, kukho izinto kuphela esingazaziyo ukuba zenziwe njani. Ukuba i-HDD ineempazamo ezingama-80%, nokuba uzilungisa usebenzisa into efana neHirensBootCD okanye efanayo, ekugqibeleni i-HDD iyakukunika iintloko ezingaphezulu kuneengxaki ezisonjululwe ... ungasebenzisa ukubuyisa idatha ekhethekileyo okanye izixhobo zokulungisa icandelo. (okanye into enjalo), kwaye i-HDD ingcono ... kodwa mhlobo, nokuba uyayenza loo nto, ubuncinci andizukubeka ulwazi lwam emngciphekweni kwi-HDD eyayineengxaki ezininzi 😉

        I-eBay yimarike enkulu yamazwe aphesheya, iqhinga lokuphepha ukuba namava amabi kukuthenga izinto kubathengisi abanokwaneliseka okuphezulu kakhulu (ngaphezulu kwama-95%), kunye nenani leBIG lokuthengisa. Ke ukuba uthenga kumfana, umzekelo, onelisekile ngama-98% kwizivumelwano ezingama-50.000 XNUMX, ndoda, akunakulindeleka ukuba ube namava amabi kuye.

        Undishiye ndibhidekile nale!, .... kuqala uthi kukuthenga kwabo banenqanaba elikhulu lokwoneliseka okungaphezulu kwama-95% kunye nenani elikhulu kwintengiso, emva koko undixelele ukuba ndithenga kulowo unama-98% ulwaneliseko Izivumelwano ezingama-50.000 zenziwe, akunakulindeleka ukuba uthetha ntoni ngale nto?

        Yintoni ebonwe kumthengisi ofanayo kwiintlobo ezahlukeneyo zeenkwenkwezi,… kwenzeka ntoni ukuba amanqaku azinzile ezinkwenkwezini? Umzekelo: 5 iinkwenkwezi eziluhlaza (99%) ezintle, ezi-3 ezimthubi (10%) ezingathathi hlangothi, iinkwenkwezi ezi-5 bomvu (5%) ongekhoyo.

        Ngaba izinto ezi-3 okanye ezi-5 ezimbi zithetha ukuba akunakulindeleka?

          Ewe, ukuba uthenga into kumntu othengise ama-50.000 98 kwintengiso ene-XNUMX% yokufumana ulwaneliseko, akunakulindeleka ukuba ube namava amabi, oko kukuthi, kunzima ukukhutshwa e-esta

          Umzekelo jonga le ntoUkuba ujonga ekunene kuyabonakala ukuba umthengisi unamkelo% 99,4% yetotali engama-9362, enyanisweni ... ukuba ucofa igama lakhe / isiteketiso, uya kubona ngokweenkcukacha iivoti zakhe ezilungileyo nezingalunganga, cala, njl.

        Komnye umbuzo, ukuze ukwazi ukuthenga kwi-eBay, kufuneka ubhalise kwelo phepha?, Kwaye ke ukwazi ukubeka iodolo ngokuthe ngqo kwi (eBay) okanye ngokuthe ngqo kumthengisi?, Ndicinga ukuba kufanele kubekho irhafu yokusetyenziswa Kuthatha ixesha elingakanani ukufumana iodolo? Umzekelo: Ndifuna i-HDD kwi-IDE, ngokukhethekileyo i-250 GB, okanye ubuncinci (i-120 okanye i-100 GB). Ndifuna iprosesa kwi-Intel (R) Pentium (R) M 780.
