Dab tsi yog qhov txawv ntawm ib lub xeev tsav thiab lub tshuab hard drive?

(SSD) Solid State Drive

Solid State Drives (Solid State Drives) yog cov hard drives ua los ntawm cov khoom siv hluav taws xob hauv lub xeev cov cim xeeb nti. Muaj ob hom kev cia khoom rau cov khoom siv hauv xeev, ib qho yog siv FLASH chips ua cov ntaub ntawv khaws cia, thiab lwm yam yog siv DRAM ua cov ntaub ntawv khaws cia. Tam sim no lub mainstream siv FLASH flash nco chips li cia xov xwm. Kev khiav hauj lwm kub ntawm cov khoom siv hluav taws xob yog qhov dav, xws li ntawm 0 txog 70 degrees rau cov khoom lag luam thiab -40 txog 85 degrees rau cov khoom lag luam. Tam sim no, lub ntsiab interfaces yog M.2 thiab SATA3.

(HHD) mechanical hard drive

Cov neeg kho tshuab hard disk yog ib txwm zoo tib yam hard disk, uas yog tsim los ntawm: platter, sib nqus lub taub hau, platter rotating ncej thiab tswj lub cev muaj zog, sib nqus taub hau maub los, cov ntaub ntawv converter, interface, cache thiab lwm yam. Lub taub hau hlau nplaum tuaj yeem txav mus raws cov kev taw qhia radial ntawm lub platter, ntxiv rau kev sib hloov ceev ntawm lub platter ob peb txhiab revolutions ib feeb, lub taub hau hlau nplaum tuaj yeem muab tso rau ntawm qhov chaw ntawm lub platter los ua cov ntaub ntawv nyeem thiab sau cov haujlwm. Cov ntaub ntawv raug sau rau hauv disk los ntawm cov khoom siv hluav taws xob los ntawm lub taub hau hlau nplaum uas nyob ze rau ntawm qhov chaw sib nqus thiab cov polarity hloov pauv los ntawm cov khoom siv hluav taws xob tam sim no, thiab cov ntaub ntawv tuaj yeem nyeem nyob rau hauv txoj kev sib txawv. Raws li cov cuab yeej precision, lub hard disk yog yeeb ncuab ntawm plua plav, yog li cov huab cua nkag mus rau lub hard disk yuav tsum tau lim.

Kev sib piv kev ua tau zoo ntawm cov khoom siv hauv lub xeev thiab cov khoom siv kho mob nyuaj

1. Sau nrawm sib piv:

Kev nyeem ntawv ceev txwv ntawm HDD hard disk yog 200M ib ob, thiab kev sau ntawv nrawm yog qhov nyuaj tshaj 100M ib ob; SSD hard disk muaj txiaj ntsig zoo hauv kev sib kis ceev. Noj MX series SSD ua piv txwv, qhov sib txuas sib txuas ceev yog siab li 510MB / s, kev nyeem ntawv nce mus txog 560MB / s, thiab nws tsuas siv ob peb feeb rau 1G cov ntaub ntawv kom tiav.

2. Kev sib piv cov ntaub ntawv kev ruaj ntseg:

Cov tsoos HDD hard disk nyeem thiab sau cov ntaub ntawv los ntawm kev nyeem cov platter nrog lub taub hau sib nqus. Thaum lub sij hawm kev sib hloov ceev ceev, kev sib tsoo ntawm lub platter thiab lub taub hau sib nqus feem ntau yuav ua rau cov ntaub ntawv puas tsuaj, thaum SSD hard disk tsis muaj platters, tsuav yog cov chips tsis deformed los ntawm sab nraud extrusion. , cov ntaub ntawv tuaj yeem khaws cia kom nyab xeeb, yog li qhov sib txawv ntawm cov cuab yeej hard drives thiab cov khoom siv hauv lub xeev ntawm cov ntaub ntawv kev ruaj ntseg yog qhov loj heev.

3. Kev sib piv kev lag luam yooj yim thiab yooj yim:

SSD hard drives muaj txiaj ntsig zoo hauv kev ceev, tab sis vim yog tus nqi siab dua, tus nqi tam sim no ntawm SSD hard drives feem ntau yog 2-3 npaug ntawm HDD hard drives, tab sis nrog kev txhim kho txuas ntxiv ntawm Moore Txoj Cai, qhov ntom ntom ntawm cov khoom- lub xeev tsav NAND flash nco chips yuav nce Loj, lub peev xwm cia tau siab dua thiab siab dua. Loj-muaj peev xwm hard drives xws li 500G solid-state hard drives thiab 1T solid-state hard drives tuaj yeem ua tau raws li cov neeg siv xav tau, thiab cov nqi kev ua haujlwm tau zoo heev. Nyob rau tib lub sijhawm, SSD lub xeev lub zog tsav muaj qhov zoo ntawm qhov ntim thiab zoo, thiab muaj kev poob siab zoo dua, uas yooj yim dua rau cov neeg siv uas feem ntau nqa lub computer mus ncig ua lag luam.

4. Kev siv hluav taws xob thiab suab sib piv:

Lub high-speed rotating platter ntawm HDD hard disk xav tau ib tug high-power motor tsav, thaum SSD hard disk tsis xav tau lub cev muaj zog tsav, yog li ntawd lub zog noj ntawm HDD hard disk yog ntau loj. Vim yog kev sib hloov ntawm lub cev muaj zog thaum lub sijhawm ua haujlwm, yuav muaj kev vibration me ntsis thiab kev co. Suab nrov, thiab SSD hard drives tsis muaj teeb meem no.

5. Kev sib piv muaj peev xwm:

Cov tsoos HDD hard disk muaj peev xwm loj, tam sim no lub ntsiab hard disk muaj peev xwm yog 500G ~ 2TB, thiab tam sim no lub peev xwm tseem ceeb ntawm SSD hard disk yog 128G lossis 256G. ntawm kev nyiam.

6. Kev sib piv ntawm seismic muaj peev xwm

Cov tsoos mechanical hard disk muaj lub siab ceev sib nqus lub taub hau sab hauv, thiab nws qhov kev poob siab tsis zoo heev. Yog li ntawd, yog hais tias tus neeg kho tshuab hard disk feem ntau siv nyob rau hauv kev txav los yog nyob rau hauv ib qho kev vibration ib puag ncig, nws yog ib qho yooj yim mus ua puas lub hard disk. Cov neeg kho tshuab hard disk tau txais kev daws teeb meem nti, tsis muaj lub taub hau sib nqus sab hauv, tsis ntshai ntawm kev sib tsoo, kev poob siab thiab kev co, thiab muaj kev poob siab super, yog li nws yuav tsis cuam tshuam rau kev siv ib txwm siv txawm tias muaj kev kub ceev lossis txawm nrog flipping thiab tilting. Qhov ua tau ntawm cov ntaub ntawv poob yog qhov tsawg kawg nkaus thaum muaj kev poob qis lossis kev sib tsoo nrog cov khoom nyuaj.

Cia peb tham txog qhov xaus ua ntej: yog tias cov peev nyiaj tsawg tsawg, yuav lub zog-xeev tsav, thiab qhov kev xaiv tseem ceeb yog kev sib xyaw ntawm cov khoom siv hauv xeev thiab cov cuab yeej siv zog, tab sis yog tias cov peev nyiaj muaj ntau, xaiv cov khoom siv hluav taws xob ntshiab. .

Ua ntej ntawm tag nrho cov, lub peev xwm ntawm solid-state drives tsis tsawg heev. Tej zaum nws yuav yog vim qhov tseem ceeb ntawm cov khoom siv hauv xeev yog 128GB / 256GB ntawm lub peev xwm me me, yog li peb xav tias lub cim xeeb me me.

Cov neeg feem coob tuaj yeem lees txais tus nqi ntawm 512GB SSD ntawm tus nqi ntawm ib ncig ntawm 1,500 yuan. Kuj tseem muaj ntau lub zog-xeev tsav nrog lub peev xwm ntau dua 4TB siv hauv cov servers, tab sis tus nqi tshwj xeeb yog kim.

Qhov zoo ntawm cov neeg kho tshuab hard drives yog tias cov cuab yeej siv tau zoo heev, thiab tus nqi tsis kim heev. Yog tias koj hais tias kev nyeem ntawv qeeb, kev nyeem ntawv yuav tsis qeeb rau Africa.

Txawm hais tias lub xeev muaj peev xwm ncav cuag ob peb zaug ntawm kev nyeem ntawv ceev ntawm lub tshuab hard drive, qee zaum, qee cov yeeb yaj kiab thiab cov ntaub ntawv tsis tau zoo dua qub thaum muab tso rau hauv lub xeev ruaj khov.

Tab sis ceev faj, tsis txhob xaiv cov khoom siv qeeb qeeb, 5400 rpm thiab 7200 rpm yog qhov sib txawv heev.

Yog li ntawd, qee lub tshuab hard drive tshwj xeeb yog qeeb thaum nyeem ntawv thiab sau cov ntaub ntawv tawg, thiab lub sijhawm no, kev ceev ntawm cov khoom siv hauv xeev yog kaum ob lub sijhawm zoo dua li nws.

Txhawm rau muab qhov piv txwv zoo, tom qab lub kaw lus tau siv sijhawm ntev, lub sijhawm khau raj ntawm lub tshuab hard disk feem ntau yog 1 feeb, thiab qee qhov xwm txheej hnyav, nws tuaj yeem qhib rau 3 feeb, thiab lub hard disk yog. tseem nyeem tej yam tom qab nkag, thiab nws yuav siv sij hawm ib pliag ua ntej nws yuav siv tau.

Yog tias koj siv lub xeev lub zog tsav, koj tuaj yeem nkag tau hauv ntau dua 10 vib nas this, thiab koj tsis tas yuav tos tom qab nkag.

Nws yog qhov tseeb tias SSDs muaj qhov txwv ntawm tus lej sau.

Txawm li cas los xij, qhov tseeb, txawm tias koj sau ntau lub zog-xeev tsav no, nws tuaj yeem siv tau ntev, thiab lub neej ntev yog proportional rau lub peev xwm ntawm lub zog-xeev tsav. Thaum lub peev xwm doubles, lub neej yuav ob npaug. Nws kwv yees tias nws yuav siv sijhawm kaum xyoo los sau tag nrho 128GB solid-state drive. .

Qhov laj thawj tseem ceeb ntawm kev ua tsis tiav hauv SSDs niaj hnub no yog qhov kev xav tsis zoo ntawm lub zog hluav taws xob, es tsis ua haujlwm ntawm lub cim xeeb flash.

Vim nws cov qauv siv tshuab, lub tshuab hard disk yog cov cuab yeej precision. Kev vibration thiab kub siab yuav ua rau kev puas tsuaj rau cov neeg kho tshuab hard disk. Txawm hais tias nws tau khaws cia zoo, lub disk tseem yuav puas.

Ib tug neeg kho tshuab hard drive feem ntau yuav tawg rau ob peb xyoos, thiab nws yog tiag tiag tsis zoo li ib tug solid-state hard drive.

Tau kawg, nws tsis yog qhov ua tau zoo rau nruab lub khoos phis tawj nrog kev sib xyaw ua ke ntshiab-lub xeev, vim tias muaj peev xwm loj SSDs tiag tiag kim heev.
