Muaj yog ib qho nyuaj drives, nruj heev heev rau laptops. Lawv loj yog me dua cov "HDD", tsim los rau installation nyob rau hauv ib tug "desktop" computer - 2.5 nti. hard drive ceev rau ib tug laptop - feem ntau yog 4200 los yog 5400 rpm. Kev khiav hauj lwm xws drives feem ntau ntawm Harnessing SATA interface. Yus ib tug siab kuj mus rau ib tug kev hloov nyob rau hauv txoj hauj lwm, uas yog ib zajlus kom nyob rau hauv view ntawm lub specifics ntawm kev siv phau ntawv sau.

Cov qhov tseem technologically advanced hom nyuaj drives - SSDs. Lawv, nyob rau hauv tus, yuav ntshai raws li ib tug nyias muaj nyias ib chav kawm ntawv ntawm pab kiag li lawm, vim lawv cov qauv muaj tsis muaj mus paib. Cov ntaub ntawv nyob rau hauv no hom ntawm hard disk drives yog sau ntawv mus rau nyem nco. Devices ntawm no hom muaj ob zoo thiab disadvantages.

Muaj ntau ntawm lub ntiaj teb no ua PC manufacturers yog adapting lawv Hoobkas kab rau zus tau tej cov pab kiag li lawm, nws yog txawm peem rau nrog khoom hauv lub xeev drives. Qhov no hom ntawm cov zog drives yog kim kim dua li cov nyob rau hauv cov qauv ntawm cov uas tus yam ntsiab yog tam sim no. Txawm li cas los, nyob rau hauv kev sib piv nrog lawv, lawv yog yus muaj los ntawm cov uas tsis muaj zog noj, yuav luag tag nrho cov uas tsis muaj suab nrov thaum ua hauj lwm, nyob rau hauv ntau - tsawg ceeb thawj. Tus kwv tij mus rau lub ceev ntawm cov ntaub ntawv kis tau tus mob tej zaum yuav tau muab sau tseg hais tias ib tug raug tus nqi rau cov khoom-xeev nyuaj drives - 300-400 MB / sec, uas yog heev dlej nyob rau tom qab ntawm cov kev sib txuas lus qauv kev txhawb los ntawm niaj hnub lub computer.

interfaces

Successful installation ntawm lub hard disk nyob rau hauv lub PC yog lom zem ntau nyob rau hauv lub xub ntiag ntawm qhov yuav tsum tau interfaces. Xav txog cov specifics ntawm feem ntau kev sib txuas lus qauv nyob rau hauv kev ua lag luam ntawm lub computer cov khoom. Qhov no yuav pab tau rau correlating neeg siv kev pab raws qib thiab hom "hard disk", uas yog optimally haum mus ntsib lawv.

Ntawm cov feem ntau interfaces rau txuas lwm nyuaj drives - USB. Yog li active sib txuas lus txheem yuav tsum tau muab nthuav nyob rau hauv txawv versions - 1, 2, thiab 3. Cov kev ceev ntawm lub hard disk yog ncaj qha nyob rau nws compatibility nrog cov technology. Hais txog lub 1 version ntawm lub interface, koj yuav hais tias thaum nws yog siv mus rau kis cov ntaub ntawv nyob rau hauv 12 Mbits / sec, 2nd kom cov ntaub ntawv sib ntawm speeds mus txog 480 Mbit / s, 3 tiam ntawm lub USB-interface muab ib tug hais rau 5 Gbit / s. Yog hais tias koj npaj siab yuav mus siv tus ntaus tsis tsuas khw ntaub ntawv, tab sis kuj, piv txwv li, rau nruab ua si los yog cov kev pab cuam, nws yog ib qhov zoo tshaj plaws yog hais tias nws yog kom muaj tam sim no USB interfaces - nyob rau hauv lub 2nd version, thiab txawm zoo dua nyob rau hauv lub thib peb.

computer lwm hard drive kuj yuav kev cob cog rua nrog ib tug FireWire interface. Nws yog yus muaj los ntawm siab cov ntaub ntawv tus nqi - txog li 400 Mbit / sec. Nws yog zoo heev thaum ua hauj lwm nrog video ntaub ntawv.

Xav txog cov qauv siv thaum txhim kho sab hauv drives nyob rau hauv ib tug PC hom. Xam tias yog ib tus obsolete, tab sis tseem nrov interface - IDE.

Nws muaj peev xwm kis cov ntaub ntawv ntawm speeds txog 133 MB / sec. Common nyob rau hauv desktop PCs - lom zem ntau vim hais tias ntawm lub theej loj npaum li cas ntawm connectors mus rau ib tug uas tsis yog-pom yam ntxwv laptop qauv.

SATA interface - qhov tshwm sim ntawm kev txhim kho cov IDE txheem. Nws tso cai rau koj mus rau cov hloov ntaub ntawv ntawm speeds mus txog rau 300 MB / sec. Nws yus siab tiv thaiv cuam tshuam. Lug siv nyob rau hauv phau ntawv sau computers - ua tsaug rau lub kuj me me luaj li cas ntawm cov connector, raws li zoo raws li ib tug zoo cov ntaub ntawv tus nqi.

SCSI interface, raws li peb sau tseg saum toj no, yog muab tso rau tsuas yog nyob rau hauv lub servers. Tsis tas li ntawd yus los siab cov ntaub ntawv tus nqi - txog 320 MB / sec. Muaj ib tug upgraded kev hloov kho ntawm qhov qhia interface - SAS. HDDs uas khiav lag luam nyob rau hauv nws cov koom tes tej zaum yuav muab cov ntaub ntawv pauv rau qhov kev txiav txim ntawm 12 Gb / s tus nqi.

Kev Cai rau xaiv ib tug hard disk

Interface Specifications peb tau sib tham txog saum toj no yuav suav hais tias raws li ib qho tseem ceeb kev thaum xaiv ib tug nyuaj tsav. peb kuj tsa ib tug xov tooj ntawm lwm yam tseem ceeb tsis - xws li cov kev ceev ntawm kev sib hloov ntawm lub ntsiab devaysa daim ntawv ceeb. Tab sis feem ntau tej zaum, ib tug tseem ceeb nam nyob rau hauv cov kev xaiv ntawm cov pom qauv devaysa yam ntxwv - hard disk nco. Nyob rau hauv ntau txoj kev, qhov kev xaiv no yog subjective - ntau cov neeg siv xav sai "hard drive" tshaj qhov ib tug nyob rau hauv uas nws yuav tsum tau tso ib tug loj tus naj npawb ntawm cov ntaub ntawv. Txawm li cas los, cov hard disk muaj peev xwm - tseem thawj qhov uas thim cov xim ntawm ntau cov neeg siv.

Qhov tseem ceeb tshaj nam ntawm cov kev xaiv ntawm "Winchester" - ib co ntawm nws cov nominal yam ntxwv (e.g., compatibility nrog cov no los yog lwm yam interfaces) yuav tsum tau tshaj nrog rau cov kev sib txuas lus muaj peev xwm ntawm lub PC. Nws thiaj li tshwm sim hais tias lub computer hard disk yog incredibly technologically, tab sis cov nyiaj them yug rau cov qauv rau lub motherboard PC tsis txaus. Xav txog cov tseem ceeb nuances ntawm compatibility "drives" thiab ib co ntawm cov kev kho vajtse Cheebtsam ntawm niaj hnub computers.

Tseem ceeb qhov ntev ntawm compatibility

Saum toj no peb pom hais tias lub zog drives sib txawv nyob rau hauv loj. Nws kuj zoo li hais tias qhov no parameter - muaj hnub nyoog. Tiam sis feem ntau nws hloov tawm mus rau yuav luag decisive. Lub fact tias cov installation ntawm lub hard disk nyob rau hauv koj lub PC los yog laptop rau cov uas tsim nyog rau thaj tsam yuav tsis tshua muaj neeg yooj yim, yog tias cia loj yog heev me me, thiab yog li ntawd sub-pom nyob rau hauv cov nqe lus ntawm kev siv ntawm cov muaj qhov chaw nyob rau hauv cov qauv devaysa. Nws yuav yuav luag tsis yooj yim sua yog hais tias tus ntev heev loj - "hard drive" yog tsuas yog tsis haum rau hauv lub computer.

Ntawm cov hoob kawm, qhov no txawv yog raug mas rau laptops, raws li cov teeb meem nrog qhov kev tso kawm ntawm tus hard disk nyob rau hauv lub PC "desktop" feem ntau tsis tshwm sim (lom zem ntau vim cov nyob rau ntawm ntau yam los tsis ua cas accessories). Yog li ntawd, thaum npaj mus yuav ib tug tshiab hard drive rau koj lub laptop, koj yuav tsum paub dab tsi lub caij nyoog loj ntawm lub tam sim no. Saum toj no peb pom hais tias yog lub uas "nyuaj drives" nrog ib tug daim ntawv ceeb ntawm 2.5 nti nyob rau hauv lub duas paub hom computers. Tiam sis peb yuav tsum dais nyob rau hauv lub siab hais tias ib qho nyuaj drives ntawm 1.8 nti teev nyob rau hauv ib co qauv ntawm cov laptop.

Tau tshaj kev sib txuas lus qauv

Compatibility yuav tsum kuj yuav sib txuas lus thiab "hard drive" interfaces thiab PC motherboard. Lub ntsiab caveat ntawm no - qhov sib txawv nyob rau hauv lub versions ntawm cov ntaub ntawv pauv cov qauv. Yog li ntawd, muaj peb versions ntawm lub SATA interface. Nws yog ib qho tseem ceeb tias cov uas tsim nyog kev sib txuas lus txheem kev txhawb los ntawm lub khw, yog tseem tau tshaj cov motherboard. Nws yuav tshwm sim hais tias ib tug neeg siv yuav ib qho kim, kuas cov kev pauv ntawm cov ntaub ntawv nyob rau hauv lub tam sim no cov txheej txheem SATA 3 nyuaj tsav (tus nqi ntawm xws qauv yuav ua tau nyob ib ncig ntawm 10 txhiab. Tshiav.), Tab sis tus computer yuav tsis tau tag nrho cov nyiaj them yug. PC tswv, yog li, yuav ho overpay.

Cov tib mus rau lub correlation kev txhawb los ntawm "hard disk" thiab PC USB qauv. Yog hais tias lub hard drive no yog tsim los txuas ntawm ib tug interface USB 3.0, tab sis lub motherboard tsis txhawb nws, hauj tuition ntawm cov txheej txheem thiab yuav tsis tau mas pom tau hais. Hais txog cov FireWire interface, koj yuav hais tias yuav pab txhawb nqa nws cov hard disk (nqi ntaus ntawv kuj yuav ncaj ncees - .. 8-10 txhiab rubles), koj yuav tsum xyuas kom meej tias koj lub PC yog nyob rau hauv tus tshaj nrog nws. Qhov no kev sib txuas lus standard yog raug rau laptops, tab sis yog tsis tuaj kawm ntawv nyob rau hauv ntau PC "desktop." Ntawm cov hoob kawm, nyuaj drives, FireWire them nyiaj yug, raws li ib tug txoj cai, thaum tseem tsis tau tshaj USB interfaces, thiab nws yog ib co tsis pom hais tias tus ntaus ntawv yuav tsum tau uas tsis yog-haumxeeb vim tsis muaj ib tug FireWire chaw nres nkoj nyob ib PC. Tab sis yog hais tias tus neeg siv, piv txwv li, yuav tsum koom nrog lub feem ntau pom tseeb kev sib tw kom zoo dua ntawm FireWire - npaum lag luam los ntawm cov kev yees duab cov ntaub ntawv, nws yuav tsis tau txais cov kev kawm tau ntawm lub zog tsav.

Lub zoo npaum li cas ntawm

Raws li peb muab sau saum toj no, lub volume raws li lub ntsiab yam ntxwv ntawm xws li ib tug ntaus ntawv, zoo li ib tug nyuaj tsav - qhov no yog ib tug heev subjective parameter. Muaj ntau cov neeg siv yog txaus, wb hais tias, ib tug ob peb gigabytes ntawm disk qhov chaw - piv txwv li, yog hais tias lawv ua hauj lwm feem nrog cov ntaub ntawv. Ib tug neeg thiab nyuaj tsav terabyte nkawd roomy txaus mus yuam heev tso loj tagnrho cov multimedia cov ntsiab lus - yeeb yaj duab, duab, suab paj nruag.

Nws xav pom npaum li cas ntawm cia yog tsis yooj yim. Tab sis lub tswvyim ntawm "qhov ntau - lub zoo dua" - yog tsis ib txwm qhov zoo tshaj plaws kev xaiv, dua los ntawm ib qho nyiaj txiag taw tes ntawm view. Koj muaj peev xwm siv rau hauv txoj kev, ib tug loj hard drive - 1 kab mob TB. Tag nrho cov terabyte yog li no muaj - tab sis nyob rau hauv kev xyaum nws yuav siv tau yuav luag ib nrab. Nyob rau hauv cov ntaub ntawv no thaum twg yuav ib tug tsawg capacious, tab sis tus tsav sawv cheaper tso nyiaj yuav siv tau los txhim kho txoj kev kawm ntawm koj lub PC los yog laptop (piv txwv li, yuav ntxiv RAM module los yog ib tug ntau haib txias rau lub processor).

Raws li ib tug xov tooj ntawm nws-tshwj xeeb, lub hard drive 500 GB - lub zoo tshuaj rau feem ntau ntawm cov neeg siv kev pab raws qib. Yog li ntawd, nyob rau hauv "hard drive" ntawm lub sib nug xov volume yuav muab tso rau txog 100-150 txhiab. Duab nyob rau hauv zoo zoo, nruab 100-150 niaj hnub ua si. Yog hais tias tus tswv ntawm lub PC - tsis yog ib tug collector fotoshedevrov thiab tsis yog ib tug gamer, nws yog tsis zoo li hais tias nws ntiav neeg ua tsawg kawg yog ib nrab ntawm cov coj kev pab. Tab sis, ces lub caij uas yuav muab rau nws ib tug hard disk ntawm 500 GB, yuav xwb yuav tsis txaus yog tias nws, nyob rau hauv lem, yog xav nyob rau hauv photography thiab ua si. Txawm li cas los, tus nqi ntawm cov "hard disk" yog ntshai raws li ib tug ntawm qhov zoo tshaj plaws nyob rau hauv cov nqe lus ntawm cov kev pab raws qib uas daws tau tshaj cov neeg siv.

muab ceev

Ib qho tseem ceeb parameter uas characterizes nyuaj tsav - yog lub turnover tus nqi ntawm cov phiaj. Nrog kev hwm rau nws muaj peev xwm yuav hais tau tias nws yog ib qho tseem ceeb los ntawm tus taw tes ntawm view ntawm lub cov ntaub ntawv hloov lwm lub tsev tus nqi raws li tau zoo raws li lub operating system tuav lub zog ntawm ntau yam ntaub ntawv. Yog hais tias lub "hard drive" yog siv raws li lub ntsiab, uas yog, nws yog tsim nyog khiav, nws ntsia cov kev pab cuam thiab kev ua si, nws yog zoo dua yog hais tias peb xav txog tus yam ntxwv yuav tsum qhia nyob rau hauv loj qhov ntau li sai tau. Yog hais tias ib tug neeg yuav ib tug thib ob tsav nyuab, tsim mas rau khaws cia cov ntaub ntawv, nyob rau hauv qhov kev txiav txim cov muab ceev cov phiaj - tsis tseem ceeb tshaj plaws taw qhia.

Lub siab dua tus nqi ntawm qhov ntsuas no, qhov ntau kim cia. Nyob rau hauv qhov kev txiav txim, lub them nyiaj tshaj rau siab ceev txawm lub fact tias lawv muaj yog tsis yuav tsum tau, yuav, dua, yuav undesirable. "Winchester" nrog ib tug kev sib hloov ceev ntawm disk emits ho ntau suab nrov tshaj ib tug uas puv coj tus, thiab yog yus muaj los ntawm tus muaj hwj huam noj. Lub pom tus nqi rau niaj hnub nyuaj disks, nyob rau hauv uas tau zoo kev txiav txim siab ntawm feem ntau ntawm cov neeg siv kev pab raws qib - 7200 rpm.

cache nco

Ntawm cov tseem ceeb ntsuas ntawm tsav kev ua tau zoo - cache. Cycling no muaj kev pab, ib tug nyuaj tsav yuav ho kom cov txheej txheem kom ua tau ntau ua hauj lwm nrog cov ntaub ntawv. Lub cache tsau lub feem ntau heev lus nug algorithms rau tej kev pab nyob rau hauv koj lub computer. Yog hais tias ib co ntaub ntawv yog nyob rau hauv lub cache, tus "Winchester" yog tsis muaj yuav tsum tau mus nrhiav rau lawv nyob rau hauv lub qhov chaw ntawm RAM los yog cov ntaub ntawv. Qhov loj qhov cache, lub zoo dua. Tiam sis muaj ntau cov kws txawj pom zoo kom lub zoo nqi coj mus rau lub Performance index - 64 MB.

Yog hom ib qho tseem ceeb?

Nws puas paub xaiv ib tug nyuaj tsav, tag nrho lwm yam uas tau sib npaug zos, ntawm lub hom? Lub views ntawm nws-cov kws txawj thiab cov neeg siv ntawm qhov teeb meem no yog sib txawv heev. Qhov no siv tau ob qho tib si mus rau lub tswv yim pom zoo siab rau lub hom, thiab cov ntsiab lus ntawm view on qhov zoo tshaj ntawm drives manufactured los ntawm ib lub chaw tsim tshuaj paus. Ib txhia cov neeg siv yuav tuab nws tsis tshua zoo, tso tawm los ntawm lub Samsung, ib qho nyuaj tsav xyuas los ntawm lwm cov tswv devaysa Korean hom tej zaum yuav tsawg siab. Ib txhia ntawm NWS-cov kws txawj qhuas hom Hitachi, Toshiba, lwm tus neeg tsis xav txog lawv yuav tsum tau ib yam dab tsi zoo dua qhov sib txeeb. Txawm li cas los, cov tuam txhab uas muag - kev ua lag luam thawj coj. Qhov tseeb yog, nyob rau hauv txhua rooj plaub, yuav tsum tau raug xam tias yog li tseem ceeb. Raws li txoj cai ntawm tus thawj coj ntawm ib tug heev kev sib tw ua lag luam ntawm lub computer accessories tsis tuaj ib qho yooj yim. Qhov no tej zaum muaj txhawb mus rau lub siab zoo ntawm manufactured khoom.

Yog li ntawd, yog hais tias peb xav tau ib tug nyuaj tsav mus rau ib tug PC los yog laptop, peb yuav tsum tau ua los ntawm cov nram qab no set ntawm no:

- size (ib qho tseem ceeb mas rau laptops - yog tsis txaus hais tias tus coj daim duab yog tsawg tshaj li tus slots muab kom haum raws li ib qho nyuaj drives, nws yog tsis tsim nyog - hais tias nws yog loj);

- txaus siab rau cov qauv (nws yog ib qho tseem ceeb uas hauj interfaces rau lub "hard drive" yog tau siab tshaj PC kev pab);

- Volume (subjective, tab sis 500GB - qhov zoo tshaj plaws qhia rau feem ntau ntawm cov neeg siv kev pab raws qib);

- daim hlau ceev (zoo - 7200 rpm);

- cache nco (optimally - 64 MB).

Nws tseem yog ntshaw tias "hard drive" twb tso tawm los ntawm lub chaw tsim tshuaj paus, uas tau ua txoj haujlwm nyob rau hauv lub ntiaj teb no kev ua lag luam nyob rau hauv cov kem ntawm cov ntaus ntawv.
