Ntsuas HDD nrawm nrog dd

Ob peb lub hlis dhau los kuv tau tso koj ib tsab xov xwm hais txog yuav ua li cas ntsuas qhov ceev ntawm HDD nrog hdparm uaZoo, lub sijhawm no kuv yuav qhia koj yuav ua li cas nrog: dd

wd-scorpio-dub

Ntsuas HDD nyeem thiab sau nrawm nrog dd

Ib qho kev txib xwb txaus kom paub txog qhov no, lo lus txib yog raws li nram no:

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

Yeej nws yuav ua li cas yog tsim thiab sau ntaub ntawv randoms rau cov ntaub ntawv (hu ua kev sim), qhov nyhav kawg yuav yog 1024MB, uas yog, 1GB, thiab qhov nws yuav qhia peb (thiab qhov twg yog qhov tseem ceeb rau peb) yuav yog qhov nrawm uas nws tau ua tiav cov 1024MB thiab lub sijhawm nws coj.

Ntawm no yog qhov screenshot ntawm lub davhlau ya nyob twg tom qab kev coj ua:

dd-hdd-nrawm

Raws li koj tuaj yeem pom, nws siv 9 lub vib nas this los sau qhov GB, uas txhais tau hais tias qhov nrawm yog 119 MB / s ... tsis yog tsis zoo 😉

Kuv yuav paub tau li cas yog tias kuv daim HDD qeeb?

Txhawm rau paub yog tias koj lub zog nyuaj qeeb koj tsuas yog yuav tsum paub tias qhov pib ib qhov nrawm tshaj 50 MB / s yog qhov lees paub (Kuv rov hais dua, siv tau, tsis yog super ceev). Yog tias koj lub hard drive tsis ntsuas lossis koj xav tau nrawm dua lossis SSD, Kuv xav kom koj saib hauv cov khw tshwj xeeb uas lawv yuav qhia koj thaum nws los txog yuav lub zog nyuaj thiab nug, lawv yuav qhia qhov nyuaj tsav uas koj xav tau raws li koj cov peev nyiaj lossis kev xav tau. Hauv kuv tsev neeg lub desktop PC nrog HDD ib txwm muab rau kuv 70 MB / s. Yog lawm, yog tias nws yog SSD lossis RAID thiab qhov "lees paub" ceev tsis zoo ib yam ????
Yog tias koj xav tau lub hard drive rau lub server nws yeej yuav zoo siv SSD, tshwj tsis yog tias nws paub tseeb tias tus neeg rau zaub mov xav tau ntau qhov chaw cia yog li koj muaj HDD qeeb qeeb uas muaj ntau lub peev xwm lossis koj nqis peev muas SSD nyuaj tsav thiab tsim kev tawm tsam tua neeg.

Qhov kawg!

Yeej yog qhov no, Kuv vam tias nws tau muaj txiaj ntsig zoo rau koj.
