Uas yog zoo dua: SSD los yog HDD? Yuav ua li cas yog qhov txawv ntawm SSD thiab HDD?

Thaum yuav ib tug tshiab PC los yog txawj tej yam ntxiv cov laus system disk ntawm ib lub computer tas seb puas tsimnyog tau rau lo lus nug: "Uas yog ib qho zoo - lub SSD los yog HDD?» Tsib lub xyoos dhau los, lo lus nug no tsis tshwm sim. Lwm yam rau pa hard disk yog tsis (nws ob lub npe - "hard drive" los yog tsuas yog "cov ntsia hlau"). Yog li ntawd, nws yog xws li ib tug ntaus ntawv rau khaws cia ntaub ntawv siv qhov txhia chaw. Tab sis tam sim no qhov teeb meem no tau hloov dramatically. Qhia, cov neeg siv xyuam xim rau cov khoom-xeev drives, uas, tab sis lawv yog kim kim, tab sis lawv ua tau zoo yog npaum li cas dua.

zaj dabneeg

Ua ntej koj yuav nrhiav tau tawm yog dab tsi yog qhov txawv ntawm cov SSD thiab cov HDD, peb noj ib nyuag cov keeb kwm xyuas thiab tshuaj xyuas cov ntaub ntawv cia technology uas yog siv nyob rau hauv txhua txhua hom kev ntaus ntawv.

Tus thawj daim ntawv qhia txog tsav rau lub hard disk (lub official lub npe) yog ua los ntawm IBM Corporation nyob rau hauv 1973 xyoo. Ces nws volume yog 60 MB (2 MB los ntawm 30 cov phiaj). Tshaj yav dhau los 40-khib xyoo, xws li muaj hloov zuj zuj, thiab lawv cov yam ntxwv tau kev zoo dua los ntawm ob peb lub sij hawm - ob qho tag nrho lub peev xwm thiab kev kawm ntawv. Tab sis yees tsis hloov. Lub hauv paus ntawm tej HDD (los ntawm cov lus Askiv lo lus «nyuaj» - ib qho nyuaj, «disk» - tsav thiab «tsav» - nyob rau hauv rooj plaub no tus tsav) lus dag phaj coated nrog ib tug ferromagnetic txheej. Nrog lub taub hau nws tsim ib yam orientation ( "sab qaum teb" thiab "sab qab teb" tug uas sib haum mus rau cov zajlus kom "0" thiab "1"). SSDs twb xub nkag tau rau hauv 1978. Tab sis coob leej ntau tus lawv siv yog tus tsis ntev los no - tus thawj PCs nrog lawv raws li nyob rau hauv lub ntsiab cia ntaus ntawv, nyob rau hauv 2009. Tau-lub xeev cia li yog raws li nyob rau hauv semiconductor cov ntaub ntawv, uas yog tsim los ntawm cov "hlwb". Nyob rau hauv xws li ib tug "cell" yuav tsum muab sau tsuas yog ob tug tseem ceeb "0" (tsis muaj cov teeb liab) thiab "1" (tej zaum tam sim no). Li no qhov txawv nruab nrab ntawm tus HDD thiab SSD. Qhov txawv ntawm cov HDD nws yog dab tsi yog siv nyob rau hauv qhuav ntawm lwm yam ntaub ntawv (silicon anti-ferromagnet) thiab ua ib txoj ntsiab cai ntawm cov ntaub ntawv cia (ICS tiv thaiv lub phaj). Hais txog nws yuav tsum nco ntsoov thaum xaiv ib tug ntawv tshiab nyob rau hauv nws chav kawm ntawv.

Lub classic version

Nyob rau hauv thiaj li yuav teb cov lus nug, yog dab tsi zoo dua - SSD thiab cov HDD, saib txhua cia ntaus ib lub zuj zus ntxiv. Yuav pib lub thib ob ntawm lawv. Qhov no yog qhov classic variant ntawm lub koom haum ntawm lub disk system. Lub ntsiab yam ntxwv ntawm lub hard drive raws li nram no:

• Peev Xwm - tus nqi ntawm cov ntaub ntawv khaws tseg nyob rau hauv tus zauv xov tooj system. Nyob rau tib lub sij hawm qhov ntsuas no nyob rau hauv lub operating system yuav sib txawv, vim hais tias ntawm no lub xam yog twb nyob rau hauv lub binary system. Tam sim no muag muaj cia muaj peev xwm ntawm 250 GB rau 8 tus kab mob TB.
• kev twb kev txuas interface yuav ua tau IDE, USB thiab SATA. Cov Thawj zaug ntawm lawv yog morally thiab lub cev obsolete thiab tsuas siv rau ib tug PC uas tau raug tso tawm 5 xyoo dhau los thiab ua ntej lawm. Qhov thib ob yog zoo rau portable cov ntaub ntawv cia. Thiab thib peb, lub ntsiab - yog tam sim no siv yuav luag universally. Nws kawg version muaj ib tug Performance index ntawm "3". Tag nrho cov pab kiag li lawm uas yuav ua hauj lwm nrog no version ntawm lub interface uas yuav kis cov ntaub ntawv thaum mus txog 6 Gb / s. Tsis tas li ntawd, SATA yog ib tug tshwj xeeb version nrog index «m», uas yog siv tsuas yog rau cov laptops thiab netbooks.
• Cov ntaub ntawv hloov lwm lub tsev tus nqi. Raws li yav tas los muab sau, nws nyob ntawm lub hom interface. Lub siab dua nws yog, qhov zoo.
• wafer kev sib hloov zaus. Tam sim no rau cov muag khoom muaj cov qauv 5400 thiab 7200. ib feeb. Yuav ua li cas no daim duab yog siab dua, qhov ntau dua qhov kev kawm.

Cov no yog cov ntsiab yam ntxwv ntawm lub hard disk. Yuav kom teb tau lo lus nug, yog dab tsi zoo dua - SSD thiab cov HDD, koj yuav tsum xav txog qhov tsis muaj khoom lub xeev drives. Yuav ua li cas nws yuav tsum tau ua li cas rau.

Paub-yuav ua li cas

Nyob rau hauv lwm txoj kev, raws li cov know-yuav ua li cas, lub SSD yuav tsis lub npe. Cov pab kiag li lawm mus rau cov muag khoom tsib lub xyoos dhau los. Tam sim ntawd xyuas yog lawv cov qib high nqi thiab loj loj. Tab sis tam sim no qhov teeb meem no yog maj hloov. Qhia, lawv muaj peev xwm nrhiav tau rau ntawm desktops thiab laptops. Main yam ntxwv muaj lub nram qab no:

• Peev Xwm - tib yam li hais tias ntawm lub hard drive. Tam sim no muaj cov qauv ntawm 32 GB mus rau 1 TB.
• Raug cov txheej txheem yuav ua tau los ntawm 19 nm mus rau 26 nm. Cov tsawg, cov kev kawm zoo, tab sis nws thiaj li tus naj npawb ntawm hlwb overwrite mus.
• Kev twb kev txuas interface. Tag nrho cov ntawm lawv yog cov uas zoo sib xws rau cov neeg yav tas los muab rau cov HDD, tsuas yog rau IDE, uas yog tsis siv rau cov SSD.
• Cov nab npawb ntawm cov sau mus. Nws yuav tsum yog los ntawm 1000 mus 5000 mus. Lub siab dua tus nqi, ntev SSD.

Raws li cov saum toj no, koj yuav tau yooj yim yuav muab ib qho lus teb rau dab tsi yog txawv los ntawm lub SSD HDD thiab hais tias ib tug yog ib qho zoo.

Piv drives

Muab piv rau cov kev ua tau zoo ntawm txhua tus ntawm cov drives tej zaum nws yuav muab sau tseg tias khoom hauv lub xeev muaj ib tug ntau dua cov ntaub ntawv tus nqi. Qhov no yog xyuas kom muaj los ntawm lub tshuab nws tus kheej. Microchips nyob rau hauv qhov kev npaj no yog ib qho zoo tshaj li cov magnetic daim hlau. Nyob rau qhov zoo ntawm no hom ntawm kawg kiag li lawm. Yog hais tias koj sib piv cov nqi thiab loj ntawm lub tsav, nws hloov tawm hais tias nyob rau hauv ib nqe ntawm 40-50 USD koj yuav tau ib tug 32 GB SSD los yog HDD 160-250 GB. Li no, cov kev xaiv ntawm feem ntau cov neeg. Nyob rau tib lub nqi nws yuav zoo dua ib tug ntau dua volume tshaj txoj kev kawm. Tsis tas li ntawd, lub siab tshaj plaws muaj peev xwm nyob rau hauv lub HDD 8 lub sij hawm ntau (1 GB rau 8 GB).

Yuav ua li cas thiab qhov twg yog zoo dua?

Tam sim no cia tus hais ntawd uas yog zoo dua - qhov SSD los yog HDD - nyob rau hauv txhua rooj plaub. Rau multimedia noj thiab chaw ua hauj lwm PCs yog zoo meej rau ib qho nyuaj drives nrog ib tug muaj peev xwm ntawm 160-320 GB. Thiab tus nqi yog tsawg tsawg, thiab qhov no loj yuav tsum txaus rau cov teeb meem yuav tsum tau solved. Ib tug zoo xws li cov teeb meem no nrog netbooks thiab nkag-qib laptops. Tab sis high-kev ua tau zoo mobile computers yuav zoo dua txawm peem SSD luaj li cas ntawm 128-256 GB. Gaming PCs, graphics workstations thiab servers yuav tsum tau yuav tsum tau yuav tsum tau ntsuas nrog cov 2 drives. Ib qho rau nruab thiab cov kev pab cuam - qhov no SSD. Thiab lub thib ob - lub zog tsav uas cia tus neeg siv cov ntaub ntawv. Qhov no yuav tau txais thiab kev kub ceev, thiab yuav tsum tau ntim rau cov ntaub ntawv cia.

tau

Raws li ib feem ntawm qhov tsab xov xwm no yog los ua ib tug kev sib piv ntawm cov HDD thiab cov SSD, qhia lawv cov ntsiab yam ntxwv, tswv yim pom zoo rau lawv siv, li nram qab no uas koj yuav tau yooj yim yuav tsum khaws cov ntaub ntawv cia ntaus uas yuav nplua koj xav tau kev pab zoo tshaj plaws.
