Qhov zoo ntawm SSDs

Fast nyeem thiab sau ceev: Flash nco yog siv raws li qhov chaw cia khoom nruab nrab, thiab kev nyeem ntawv nrawm dua li ntawm kev siv tshuab nyuaj disks. SSDs tsis siv lub taub hau sib nqus, thiab lub sijhawm nrhiav yuav luag xoom. Kev sau ntawv txuas ntxiv yog qhov zoo heev. Feem ntau cov SSD cov chaw tsim khoom yuav hais tias lawv cov SSDs muaj kev nyeem tsis tu ncua thiab sau ceev ntawm ntau tshaj 500MB / s. Nyob rau hauv xyoo tsis ntev los no, NVME SSD tuaj yeem ncav cuag 2000mb / s, lossis txawm ntau tshaj 4000mb / s. Qhov ceev ntawm SSDs tsis yog tsuas yog xav txog kev nyeem ntawv thiab sau ntawv. Lub Fast Random Nyeem thiab sau ceev yog qhov kawg ntawm SSDs, uas yog feem ntau ntawm cov haujlwm txhua hnub. Ntsig txog qhov no yog lub sijhawm tsawg kawg nkaus. The most common 7200 rpm mechanical hard disk has a seek time of 12-14 milliseconds, while SSDs can easily reach 0.1 milliseconds or even lower.
Poob siab thiab poob tsis kam: ib txwm muaj disks yog txhua yam disk-hom, thiab cov ntaub ntawv yog khaws cia hauv disk cov txheej txheem. Kev siv hluav taws xob hauv lub xeev tau ua los ntawm Flash nco cov lus (thiab hais tias tsis muaj cov ntaub ntawv tsis muaj zog, nws yuav tsis muaj cov ntaub ntawv tsis muaj zog tuaj yeem txo tau ntawm kev sib tsoo thiab poob siab. Piv nrog cov tsav tsheb ib txwm muaj, khov-lub xeev drives muaj cov kev zoo.
Tsawg zog noj: kev siv fais fab ntawm kev tsav tsheb-lub xeev drives yog qis dua li ntawm kev nyuaj tsav tsheb.
Tsis muaj suab nrov: Lub suab nrov-lub xeev drives tsis muaj neeg kho tshuab Motors thiab kiv cua, thiab lub suab nrov yog 0 decibels thaum ua haujlwm. Flash-based khov-state drives muaj kev siv hluav taws xob tsawg thiab cov khoom siv kub hauv lub xeev ua haujlwm (tab sis cov khoom lag luam muaj peev xwm ntau dua yuav tau siv hluav taws xob ntau dua). Tsis muaj cov tshuab txav sab hauv, tsis muaj cov neeg kho tsis taus, thiab lawv tsis ntshai kev sib tsoo, kev cuam tshuam, thiab kev co. Txij li thaum muaj teeb meem-lub xeev drives siv flash nco cov chips tsis muaj cov khoom siv hluav taws xob, lawv muaj cov yam ntxwv ntawm cov cua kub tsawg thiab nrawm kub dissipation.
Kev ua haujlwm dav dav ntau: Cov tawv tawv disk tuaj yeem tsuas ua haujlwm hauv thaj tsam 5 txog 55 degrees Celsius. Feem ntau cov tsav tsheb-state drives tuaj yeem ua haujlwm ntawm -10 txog 70 degrees Celsius. Cov-lub xeev tsav tsheb yog me dua thiab sib dua dua li cov tshuab hluav taws xob nyuaj ntawm tib lub peev xwm. Lub interface specifications thiab cov ntsiab lus, kev ua haujlwm ntawm cov khoom siv sib zog-lub xeev nyuaj, thiab qhov loj me kuj sib xws nrog cov tsav nyuaj. Kev ua haujlwm ntawm qhov kub ntawm nws cov chips yog dav heev (-40 ~ 85 degrees Celsius).
Lub teeb yuag: Lub Xeev Drives yog sib dua hauv qhov hnyav, 20-30 grams sib nrau dua li kev sib xyaw ua ke 1.8-nti nyuaj tsav.
