Tam sim no, SSDs yeej maj mam hloov cov paib nrig. Yog tias nyuam qhuav tsis ntev los no, SSDs ntawm me me thiab, raws li txoj cai, tau siv los txhim kho lub kaw lus, tam sim no muaj cov txhais tau 1 lub lag luam thiab ntau dua. Qhov zoo ntawm cov drives yog pom tseeb - nws yog qhov tsis muaj txiaj ntsim, kev kub ceev thiab kev cia siab. Hnub no peb yuav muab qee cov lus qhia yuav ua li cas thiaj xaiv txoj kev xaiv ntawm SSD.
Qee cov lus qhia txog xaiv SSD
Ua ntej koj yuav ib qho tshiab disk, koj yuav tsum tau them sai sai rau ntau qhov tsis muaj qhov yuav pab koj xaiv lub cuab yeej zoo rau koj qhov system:
- Txiav txim siab rau tus nqi SSD;
- Tshawb xyuas seb txoj hau kev txuas twg muaj nyob hauv koj lub cev;
- Them faj seeb rau qhov "khoom ua" disk.
Nws yog rau cov ciaj ciam no, peb yuav xaiv tus tsav, yog li cia saib txhua yam ntawm lawv cov kev qhia ntau ntxiv.
Disk peev
Lub xeev cov drives muaj ntau ntev dua cov pa luamyeeb, thiab yog li koj yuav tsis tau yuav nws rau ib xyoos. Tias yog vim li cas nws thiaj li tsim nyog los ua txoj haujlwm ntau dua rau kev xaiv qhov ntim.
Yog tias koj npaj yuav siv SSD rau lub system thiab cov kev pabcuam, ces qhov no, lub 128 GB tsav yuav zoo meej. Yog hais tias koj xav kom hloov cov disk li ib txwm, ces qhov no nws yog tsim nyog tau xaiv cov cuab yeej siv nrog ib peev xwm ntawm 512 GB los yog ntau dua.
Tsis tas li, oddly txaus, lub ntim ntawv raug rau ob lub neej thiab nyeem ntawv / sau ntawv ceev. Qhov tseeb yog tias muaj coob npaum li cas cia cov maub los muaj ntau qhov chaw los faib cov khoom ntawm lub cim xeeb.
Txoj kev sib txuas
Raws li nyob rau hauv rooj plaub nrog lwm yam khoom siv, SSD kev ua haujlwm yuav tsum txuas nrog lub computer. Feem ntau cov kev sib txuas ntawm interfaces yog SATA thiab PCIe. PCIe drives yog sai dua SATA thiab feem ntau yog ua ib daim npav. SATA drives muaj ntau lub qab ntxiag, thiab muaj ntau yam, vim lawv tuaj yeem txuas nrog ob lub computer thiab lub laptop.
Txawm li cas los, ua ntej yuav ib lub disk, nws tsim nyog xyuas seb puas muaj cov PCIe lossis SATA connectors nyob rau hauv lub niam ntawv.
M.2 yog sib txuas SSD txuas uas yuav siv tau SATA thiab PCI-Express (PCIe) cov npav. Lub ntsiab feature ntawm disks nrog xws li ib tug connector yog compactness. Nyob rau hauv tag nrho, muaj ob qho kev xaiv rau lub connector - nrog tus tseem ceeb B thiab M. Lawv txawv nyob rau hauv tus naj npawb ntawm "txiav". Yog hais tias nyob rau hauv rooj plaub thawj zaug (yaum B) muaj ib tus luj, ces nyob rau hauv ob yog ob leeg ntawm lawv.
Yog tias peb sib piv cov kev sib txuas ntawm kev sib txuas, ces qhov ceev tshaj yog PCIe, qhov twg cov ntaub ntawv xa mus cuag tau mus txog 3.2 Gb / s. Tab sis SATA - txog 600 MB / s.
Nco hom
Tsis zoo li cov pa HDDs, cov ntaub ntawv khaws cia rau hauv ib lub cim xeeb tshwj xeeb hauv cov xeev-state drives. Tam sim no drives yog muaj ob hom kev nco no - MLC thiab TLC. Nws yog hom kev nco uas txiav txim xyuas qhov chaw thiab kev ceev ntawm lub cuab yeej. Qhov kev kawm siab tshaj plaws yuav muaj nyob rau hauv disks nrog MLC nco hom, yog li lawv zoo siv yog hais tias koj tau muaj feem luam, rho tawm lossis txav cov ntaub ntawv loj. Txawm li cas los xij, tus nqi ntawm cov disks zoo li no ntau dua.
Saib kuj: NPE flash memory sib piv
Rau feem ntau hauv tsev computers, TLC drives yog zoo meej. Hauv kev ceev, lawv tsis zoo dua rau MLC, tiam sis tseem ceeb tshaj plaws rau cov khoom siv pom zoo.
Tsuj Control Chip Manufacturers
Tsis kawg lub luag hauj lwm nyob rau hauv kev xaiv ntawm cov disc plays chip manufacturers. Txhua tus tau muaj nws cov tswv thiab cov khoom ua. Yog li ntawd, SandForce nti controllers muaj ntau dua. Lawv tau qis dua thiab ua haujlwm zoo. Lub feature ntawm cov chips yog siv cov ntaub ntawv sau tawm thaum sau ntawv. Nyob rau tib lub sijhawm, tseem muaj teeb meem loj - thaum lub disk ntau tshaj ib nrab puv, nyeem ntawv / sau ntawv qis qis.
Discs nrog chips ntawm Marvel muaj kev khiav ceev zoo, uas tsis cuam tshuam los ntawm cov feem pua ntawm txhaws. Qhov teeb meem ntawm no yog qhov siab tshaj.
Samsung kuj tsim chips rau solid-state drives. Ib cov feature ntawm cov - yog encryption ntawm qhov kho vajtse theem. Txawm li cas los xij, lawv muaj qhov yuam kev. Vim muaj teeb meem nrog cov khib nyiab qiv algorithm, kev nyeem / sau ntawv yuav txo tau.
Fizon chips feature high performance thiab luv nqi. Muaj tsis muaj teeb meem uas cuam tshuam txog kev ceev, tab sis nyob rau lwm qhov tes, lawv tsis ua zoo nrog kev sau ntawv thiab kev nyeem ntawv.
LSI-SandForce yog lwm tus ntim txiag rau lub cev-state drive controllers. Cov khoom siv los ntawm cov khw no kuj muaj ntau. Ib qho ntawm cov nta yog cov ntaub ntawv compression thaum hloov mus NAND Flash. Yog li ntawd, qhov kaw cov ntaub ntawv kaw tseg, uas tig tau cov khoom ntawm tus tsav nws tus kheej. Qhov tsis zoo yog qhov txo ntawm kev tswj kev ua haujlwm ntawm qhov siab tshaj plaws ntawm qhov nco.
Thiab thaum kawg, qhov tseeb chip txiag yog Intel. Controllers raws li cov chips qhia lawv tus kheej los ntawm tag nrho cov sab, tab sis lawv yog cov ntau kim tshaj lwm tus.
Ntxiv rau cov tswv khw tseem ceeb, muaj lwm cov neeg. Piv txwv, hauv cov qauv siv nyiaj ntawm cov disks koj tuaj yeem nrhiav kev sib tshuam raws li jMicron chips, uas ua lawv txoj haujlwm zoo, txawm tias qhov kev ua tau zoo ntawm cov chips no qis dua lwm tus.
Drive ntsuam xyuas
Xav txog ob peb discs uas yog qhov zoo tshaj plaws hauv lawv cov qeb. Raws li pawg peb coj lub ntim ntawm tus tsav nws tus kheej.
Tsav mus txog 128 GB
Muaj ob hom qauv nyob rau hauv pawg no. Samsung MZ-7KE128BW nyob rau hauv tus nqi ntau txog li 8000 txhiab rubles thiab pheej yig dua Intel SSDSC2BM120A401, tus nqi ntawm qhov txawv ntawm qhov txawv ntawm 4,000 rau 5,000 rubles.
Model Samsung MZ-7KE128BW yog cov ntawv nyeem siab / nyeem sau hauv nws cov qeb. Tsaug rau nyias lub cev, nws yog ib qho zoo rau kev teeb tsa hauv ultrabook. Nws yog ua tau rau kom ua hauj lwm los ntawm kev faib RAM.
Tseem ceeb nta:
- Nyeem ntawv ceev: 550 Mbps
- Sau ntawv ceev: 470 Mbps
- Random nyeem ntawv ceev: 100,000 IOPS
- Random sau sai: 90000 IOPS
IOPS yog cov blocks uas nws muaj sij hawm los sau ntawv los yog nyeem. Qhov siab tshaj no daim duab, siab dua qhov kev ua tau zoo ntawm lub cuab yeej.
Intel SSDSC2BM120A401 tsav yog ib qho tseem ceeb tshaj ntawm cov "neeg ua hauj lwm hauv xeev" uas muaj peev xwm txog 128 GB. Nws yog tsiag ntawv los ntawm kev ntseeg siab thiab zoo meej rau installation hauv ultrabook.
Tseem ceeb nta:
- Nyeem ntawv ceev: 470 Mbps
