Chii chinonzi Solid-State Drive (SSD)?
Isu tinoziva kuti ndangariro dzinogona kuva dzemhando mbiri - inoshanduka uye isingachinji . Iyo SSD chinhu chisiri-chinoshanduka chekuchengetedza mudziyo. Izvi zvinoreva kuti data rakachengetwa paSSD rinogara kunyangwe magetsi amiswa. Nekuda kwekuvaka kwavo (ivo vakaumbwa nemwenje wemwenje uye NAND flash memory chips), solid-state madhiraivha anonziwo madhiraivha madhisiki kana solid-state disks.
SSDs - Nhoroondo pfupi
Hard disk drives ainyanya kushandiswa semidziyo yekuchengetedza kwemakore mazhinji. Vanhu vachiri kushanda pamidziyo ine hard disk. Saka, chii chakasunda vanhu kuti vatsvage imwe mudziyo wekuchengetedza misa? MaSSD akazovapo sei? Ngatitorei zvishoma munhoroondo kuti tizive kukurudzira kuseri kweSDD.
Muma1950s, pakanga paine matekinoroji maviri aishandiswa akafanana nemashandiro anoita maSDSD, anoti, magineti core memory uye kadhi-capacitor kuverenga-chete chitoro. Zvakadaro, munguva pfupi dzakabva dzaenda mukukanganwa nekuda kwekuwanikwa kwemadhiramu ekuchengetera madhiramu akachipa.
Makambani akadai seIBM akashandisa SSD mumakomputa avo ekutanga. Nekudaro, maSSD aisashandiswa kazhinji nekuti aidhura. Gare gare, muma1970, mudziyo unonzi Electrically Alterable ROM yakagadzirwa neGeneral Instruments. Izviwo, hazvina kugara kwenguva refu. Nekuda kwenyaya dzekusimba, chishandiso ichi hachina kuwana mukurumbira.
Mugore ra1978, yekutanga SSD yakashandiswa mumakambani emafuta kuwana seismic data. Muna 1979, kambani StorageTek yakagadzira yekutanga-RAM SSD.
RAM -based SSDs dzaishandiswa kwenguva yakareba. Kunyangwe ivo vaikurumidza, vakadya zvimwe zveCPU zviwanikwa uye vaidhura zvakanyanya. Mukutanga kwa1995, flash-based SSDs dzakagadzirwa. Kubva pakaunzwa flash-based SSDs, mamwe maindasitiri maapplication anoda akasiyana MTBF (kureva nguva pakati pekutadza) mwero, yakatsiviwa HDD neSSD. Solid-state dhiraivha inokwanisa kutsungirira kuvhunduka kwakanyanya, vibration, shanduko yekushisa. Nokudaro vanogona kutsigira zvinonzwisisika mitengo yemitengo ye MTBF.
Solid State Drives inoshanda sei?
MaSSD anovakwa nekuturika pamwe akabatana ndangariro machipisi mugridi. Machipisi anogadzirwa nesilicon. Huwandu hwemachipisi mu stack hunoshandurwa kuti uwane akasiyana densities. Zvadaro, vanoiswa magedhi anoyangarara matransistors kuti abate charge. Naizvozvo, data rakachengetwa rinochengetwa muSSD kunyangwe padzinenge dzadzimwa kubva kusimba remagetsi.
