Ezinyangeni ezimbalwa ezedlule ngikushiyele indatshana yokuthi ulinganisa kanjani ijubane le-HDD nge imvgYebo, kulokhu ngizokukhombisa ukuthi ungenza kanjani okufanayo nge: dd
Linganisa isivinini sokufunda nokubhala se-HDD nge-dd
Umyalo owodwa wanele ukwazi lokhu, umyalo ulandelayo:
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
Ngokuyinhloko okuzokwenza ukudala nokubhala idatha yama-randoms kufayela (elibizwa nge-test), isisindo sokugcina kuzoba yi-1024MB, okungukuthi, i-1GB, nokuthi izositshelani (nokuthi yini ebaluleke kakhulu kithikuzoba yijubane eligcwalisa ngalo lawo ma-1024MB nesikhathi esithathe ngaso.
Nasi isithombe-skrini sesiginali ngemuva kokwenza umyalo:
Njengoba ukwazi ukubona, kuthathe imizuzwana engu-9 ukugcwalisa leyo GB, okusho ukuthi ijubane belingu-119 MB / s ... akukubi 😉
Ngazi kanjani ukuthi i-HDD yami ihamba kancane?
Ukwazi ukuthi i-hard drive yakho ihamba kancane kufanele wazi ukuthi ngokuyisisekelo noma yiliphi ijubane elingaphezu kwama-50 MB / s liyamukeleka (ngiyaphinda, ngamukelekile, hhayi ngokushesha okukhulu). Uma kwenzeka i-hard drive yakho ingalingani noma ufuna esheshayo noma i-SSD, ngincoma ukuthi ubheke ezitolo ezikhethekile lapho bezokweluleka khona uma sekuziwa thenga ama-hard drive futhi ngokubuza, bazoncoma i-hard drive oyidingayo ngempela ngokuya ngesabelomali sakho noma izidingo zakho. Endabeni yami i-PC yami yedeskithophu ene-HDD ejwayelekile inginike ama-70 MB / s. Vele, uma kuyi-SSD noma i-RAID futhi ijubane "elamukelekayo" alifani ????
Uma udinga i-hard disk yesiphakeli, kuzohlala kungcono njalo ukusebenzisa i-SSD, ngaphandle kokuthi kucace ukuthi iseva idinga amandla amaningi okugcina, ngakho-ke noma ngabe une-HDD ehamba kancane enamandla amaningi noma wenza utshalomali ukuthenga ama-hard drive e-SSD nokwakha i-raid.
Isiphetho!
Ngokuyinhloko yilokhu, ngiyethemba kube usizo kuwe.
Inohlonze impela!
ngiyabonga!

Nginenkinga, lokhu kwenzeka kimi ngokusebenzisa ilaptop yeminyaka edlule nge disk ngo-5200rpm naku-sata 2
Mngani, leyo HDD ibonakala isezinsukwini zayo zokugcina ... indoda endala, ikhehla 🙁
Yebo, ilaptop yami inonyaka izelwe, iphume ishibhile kuzo zonke izici kepha ingifunda ngama-51MB / s.
Ngabe lokho kusho ukuthi bangikhumulile?
I-athikili enhle KZKG ^ Gaara, kwenzekani lapho i-HDD inamaphutha angaphezu kuka-80%?, Lokho okungalungiswa nganoma iyiphi indlela, ingabe ukuphela kwe-HDD?, Ngobuchwepheshe besimanje, kuzokwazi ukuthola i-HDD ku-IDE yama-250 I-GB noma okungenani i-100 GB futhi inani lizoba ngaphezulu noma ngaphansi kangakanani?
Ngiyabonga ^ _ ^
Ama-HDD ama-250GB ama-IDE akhona futhi ayathengiswa, hlola lapha: http://www.ebay.com/bhp/250gb-ide-hard-drive
Enye into ehluke kakhulu kungaba ukuthenga ku-eBay, ukulethwa ezweni lakho, njll.
Mayelana nenye into ongibuza yona ... Ngithanda ukusho ukuthi kwikhompyutha akukho okungenzeki, kunezinto kuphela esingakazi ukuthi sizenze kanjani. Uma i-HDD inamaphutha angama-80%, noma ngabe uyilungisa usebenzisa okuthile okufana neHirensBootCD noma okufanayo, ekugcineni ukuthi i-HDD izogcina ikunikeza ikhanda elithe xaxa kunezinkinga ezixazululiwe ... ungasebenzisa nokutholwa okukhethekile kwemishini noma imishini yokulungisa imikhakha (noma into efana naleyo), nokuthi i-HDD ingcono ... kepha mngani, noma ngikwenza lokho, okungenani ngeke ngibeke imininingwane yami engcupheni kwi-HDD ebinezinkinga eziningi 😉
Siyabonga ngempendulo ethi KZKG ^ Gaara, Ungayethemba i-eBay?, Ikhasi "lamanga" elingagunyaziwe ngaphansi kwemithetho yezwe ngalinye futhi inkampani yabazali balo iseLuxembourg lapho abanye abasebenzisi bekhalaza khona ukuthi bakhwabanisiwe ngabakhwabanisi.
Ehm, kuya ngo-😀
I-eBay iyimakethe enkulu yamazwe omhlaba, iqhinga lokugwema ukuba nokuhlangenwe nakho okubi ukuthenga izinto kubathengisi abanokwaneliseka okuphezulu kakhulu (ngaphezu kwama-95%), kanye nenombolo ye-BIG yokuthengisa. Ngakho-ke uma uthenga kumfana okuthi ngokwesibonelo aneliseke ngama-98% kusuka kuziphesheli ezingama-50.000 ezenziwe, ndoda, mancane kakhulu amathuba okuthi uzoba nokuhlangenwe nakho okubi naye.
Sawubona KZKG ^ Gaara,
Ungishiye ngididekile ngalokhu !, .... okokuqala uthi ukuthenga kulabo abanesilinganiso esikhulu sokwaneliseka esingaphezu kwama-95% nenani elikhulu ekuthengiseni, bese ungitshela ukuthi uma ngithenga kulowo onokwaneliseka okungama-98% kusuka Amadili angama-50.000 enziwe, mancane kakhulu amathuba okuthi uqonde ukuthini ngalokhu?
Yini ebonwe kumthengisi ofanayo ngezinhlobo zezinkanyezi,… kwenzekani uma amaphuzu elungisiwe ezinkanyezini? Isibonelo: izinkanyezi ezi-5 eziluhlaza (99%) ezinhle, izinkanyezi ezi-3 eziphuzi (10%) ezingathathi hlangothi, izinkanyezi ezi-5 okubomvu (5%) okungekuhle.
Ngabe ama-3 noma ama-negatives asho kakhulu ukuthi akunakwenzeka?
Yebo, uma uthenga into kothile othengise ngaphandle kokungu-50.000 98 enesilinganiso sokwaneliseka okungama-XNUMX%, mancane kakhulu amathuba okuthi uzoba nokuhlangenwe nakho okubi, okungukuthi, kunzima ngempela ukukhunyulwa 🙂
Isibonelo bheka lentoUma ubheka kwesokudla kubonakala sengathi umthengisi unokwamukelwa okungu-99,4% kwengqikithi yokuthengiswa kwe-9362, empeleni ... uma uchofoza egameni lakhe / isiteketiso, uzowabona ngokuningiliziwe amavoti akhe avumayo futhi amabi, ukungathathi hlangothi, njll.
Ulwazi oluhle kakhulu KZKG ^ Gaara, kuleso sixhumanisi osibekile ezintweni, yize lowo mthengisi enezinto ezingama-32 ezingezinhle nezingama-32 ezingathathi hlangothi, kuyabonakala ukuthi unokuthengisa okuhle okungu-99.4% (9375), okusho ukuthi … Lowo mthengisi akathembeki ngo-100%?
Komunye umbuzo, ukuze ukwazi ukuthenga ku-eBay, kufanele ubhalise kulelo khasi?, Bese ukwazi ukufaka i-oda ngqo kusuka (eBay) noma ngqo kumthengisi?, Ngicabanga ukuthi kufanele kube nentela yokusetshenziswa Kuthatha isikhathi esingakanani ukuthola i-oda? Isibonelo: Ngidinga i-HDD ku-IDE, okungcono i-250 GB, noma okungenani (i-120 noma i-100 GB). Bengifuna futhi iprosesa ku-Intel (R) Pentium (R) M 780.

Kade ngivivinya i-com porteus yokuthi ngokungalayishi kudiski kuphela ku-usb naku-40MB / s, yilokho okufanele kube sata 1, ekugcineni ukwenza isiphukuphuku ngilayishe i-porteus ngo-100% enqameni kusuka ekuhlolweni engxenyeni engiyivivile kufolda yomuntu siqu, umphumela unamandla:

Sawubona, ngicabanga ukuthi lokhu kungenziwa ukukala ijubane likaJuni kuya ekhadini le-SD noma le-MicroSD noma cha? Ngabe kufanele ngiguqule ikheli elihambisana nokuthi if lelo lekhadi noma cha?
Gracias
Ehm angicabangi kanjalo, uma ushintsha i- if ukwenza isibonelo, / dev / mmc2 ... khona-ke ongakwenza ukukopisha i-1GB kusuka ekhadini kuya kufayela, futhi kungakunika ijubane.
Inkinga ngokwenza lokhu ukuthi uma ngingaphosisi, ekugcineni ongakukala kungaba ukufunda ikhadi (ngoba uzobhala nge-HDD), futhi nedatha izodlula kwi-HDD noma kunjalo ... okungukuthi, bekungeke kube test (Ngicabanga) 100% isebenza

Kungaba yini = ukuhlolwa? Ingabe kukhona okusele kulokhu kuhlolwa kudiski? Ngiqonde ... elinye ifayili elihlala ku-1 GB elingasuswa
Ukukala isivinini sokubhala bekudingeka ukuthi kwenziwe ifayili elibizwa nge-test ku-HDD, ngemuva kokuqeda isivivinyo ungalisusa 😉

Namuhla, Oct 26, 2023, lokhu okuthunyelwe kuwusizo kakhulu ukuxilonga idiski ye-HDD ukwazi ukuthi ibhala ngokushesha kangakanani ezinhlelweni ze-Linux.
Kufanele kuqashelwe ukuthi uma ikhebuli ye-sata exhuma i-HDD yethu inephutha, lokhu kungase futhi kubangele ukuhamba kancane.
