Yintoni i SSD? A isiganeko esitsha uphuhliso lobuchwepheshe eliphezulu

inkqubela Technical okhula ngokukhawuleza. Kukho izixhobo ezintsha kakhulu lula ubomi womntu mihla. Oku kuyinyaniso ngokukodwa peripherals ezahlukeneyo computer. Ezi zixhobo eliphezulu-zobugcisa eziye zavela kutshanje eqinile-state drives. Ngokusemthethweni, i ezintsha zosasazo, kungenjalo eyaziwa ngokuba SSD, sebenzisa ezimbini iintlobo memory: of NAND kunye RAM. Drives ne memory zohlobo lwesibini zinqabile yaye ezisetyenziswa kwizicelo efuna yokusebenza fast drive nzima. NAND-drives zixhaphakile kakhulu ngakumbi. Olu hlobo lwe memory esetyenziswa iifowuni ze-PC yemveli, ngoko eli nqaku liza kuxoxwa apha NAND-drives.

Into leyo SSD yaye zahluke njani oluqhelekileyo nzima drives, andazi bonke. Ngelo xesha, umahluko ophambili phakathi kwabo - ukufunda kunye nesantya nokubhala. Le SSD ziyafana kakhulu ngaphambi zonke ezinye zosasazo. Xa isakhiwo okuqinileyo drive karhulumente kwakhona eyahlukileyo ngokwesiseko kwi-hard drive. Xa owokugqibela ezishukumayo, i SSD unalo isakhiwo monolithic enika laptop nokusebenza phantse cwaka okanye tablet. Kanye apha okuqinileyo-karhulumente drives azinazo entloko ufunde inika ngesifo asezantsi amandla kunye nokufunda ngesantya esiphezulu, kwakunye ubungakanani omncinane kwaye ihlala ophezulu ifowuni. Enye inzuzo elikhulu isixhobo SSD luhambisana kulolonke ujongano eziqhelekileyo.

Enye umsebenzisi, fumanisa ukuba yintoni na SSD, kubonakala ukuba icebo phantse akukho ziphene. Noko ke, akunjalo. Luncedo xa SSD ithathwa eliqingqiweyo "ezikhabhathini." Njengoko ngokunjalo flash-drive, drive karhulumente esiluqilima inenani anesiphelo ubhale mijikelo. Ingakumbi le isiphako ngamandla waziva ngenxa yeendleko eziphezulu isixhobo, leyo ixhomekeke umthamo wayo.

Abaninzi banomdla oko kuphela SSD, kodwa yintoni na isixhobo eyahlukileyo endukwini njengesiqhelo. SSD kungathathwa i "umzalwana enkulu" flash. Ahluke, kuqala kwiinto zonke, into yokuba USB drive yi chip enye kuphela flash-CD, kunye SSD amaninzi, yaye ingcaciso kubo ibhalwe yanjalo. Amaxesha amaninzi, ukuze kwandiswe ukusebenza esi sixhobo yayo PCB ekhwele single chip flash memory. Nabaqondisi kwi yokugcina eziqinileyo-karhulumente kwakhona kakuhle ngaphezu USB. Oku kunika SSD ukusebenza ixesha elide kakhulu.

Ngokuqinisekileyo abantu bakhathazeke ngayo lo mbuzo kwaye njani inkonzo elithi SSD. Njengoko ne-USB-drive, drive karhulumente eqinileyo, ithuba lokugcinwa akalinganiswa ngeminyaka, uze ubhale imijikelo. drive zabo abazithandayo ukusuka ezingamakhulu amahlanu amawaka ukuya kwesiqingatha sesigidi. Ngako oko, kokukhona usebenzisa ifowuni, i ngokukhawuleza iza kuba yanto. Kwandisa ubomi yokusebenza kunye abalawuli yokugcina ezizodwa apho memory iiseli zisetyenziswa ngaphezulu okanye ngaphantsi ngokulinganayo. Njengoko ixesha, abenzi eziphambili SSD akuqinisekisi iminyaka emithathu yokusebenza inkathazo-free imveliso yawo. Xa ekupheleni SSD "ezikhabhathini", oku akuthethi ukuba icebo yaphulwe. Akuyi kuba nako ukubhala iinkcukacha ezintsha, kodwa data egcinwe kwi kuya kusoloko kufumaneka.

Phakathi SSD zahluke kakhulu ngobukhulu. Ngokuqhelekileyo ke nokuba 1.8 intshi okanye 2.5 intshi, kodwa maxa wambi kukho iyunithi 3.5-intshi non-esezantsi. Zidla oxhulumene nge eSATA isinxibelelanisi. Xa uqhagamshele SSD nge USB-ujongano kuhle ukusebenzisa USB 3.0. Ngoku, kunye okuqinileyo karhulumente drives, i SSD, kukho amakhadi ukwanda, asetyenziswa laptops kunye neseva. Ukongeza, abenzi abaninzi kuvelisa uhlobo 'hybrid "SSD kunye eziqhelekileyo kwihard diski. izixhobo ezinjalo hybrid abe ngesantya esiphezulu senxulumano kwaye zibe nesithuba esaneleyo ukugcina data.

Uninzi lwabasebenzisi okwangoku Ndafunda ukuthembela eqinileyo-state drives. Fumana iimpendulo zemibuzo malunga SSD, wonke umntu uya kuba nako ukwenza isigqibo sokuba ingaba kufuneka uhlobo olutsha isixhobo yokugcina, okanye ungafumana okulungileyo hard drive endala ntoni.
