Kana vatengi vanotenga zvigadzirwa zveOPS, vanozoona kuti kune marudzi maviri emadhiraivha: SSD neHDD. Chii chinonzi SSD uye HDD? Nei SSD ichikurumidza kupfuura HDD? Ndezvipi zvisingabatsiri zveSSD? Kana uine mibvunzo iyi, tapota ramba uchiverenga.

Madhiraivha akaomarara akakamurwa kuita mechanical hard drive (Hard Disk Drive, HDD) uye solid state dhiraivha (SSD).

Iyo mechanical hard disk ndiyo yechinyakare uye yakajairwa hard disk, inonyanya kuumbwa ne: platter, magnetic head, platter shaft uye zvimwe zvikamu. Sezvine ma mechanical chimiro, iyo

mota kumhanya, nhamba yemagineti misoro, uye density yendiro zvese zvinogona kukanganisa kushanda. Kuvandudza mashandiro eHDD hard disks zvinonyanya kuenderana nekuwedzera kumhanya kwekutenderera, asi yakakwirira yekutenderera kunoreva kuwedzera kweruzha uye kushandiswa kwesimba. Nokudaro, chimiro cheHDD chinotarisa kuti zvakaoma kuchinja zvakanaka, uye zvinhu zvakasiyana-siyana zvinoderedza kukwidziridzwa kwayo.

SSD imhando yekuchengetedza yakabuda mumakore achangopfuura, zita rakazara rayo iSolid State Drive.

Iine maitiro ekukurumidza kuverenga nekunyora, kureruka kurema, kuderera kwesimba rekushandisa uye diki diki. Sezvo pasina dambudziko rakadaro kuti kukurumidza kutenderera hakugone kuwedzerwa, kuvandudzwa kwekuita kwayo kuchava nyore kupfuura iyo HDD. Nezvayo zvakanakira, yave iyo huru yemusika.

Semuenzaniso, iyo isina kurongeka yekuverenga latency yeSSD ingori zvishoma zvishoma zvegumi zve millisecond, nepo iyo isina kurongeka yekuverenga latency yeHDD yakatenderedza 7ms, uye inogona kutokwira se9ms.

Iyo yekumhanyisa data yekuchengetedza data yeHDD ingangoita 120MB/S, ukuwo kumhanya kweSSD yeSATA protocol ingangoita 500MB/S, uye kumhanya kweSSD yeNVMe protocol (PCIe 3.0 × 4) ingangoita 3500MB/S.

Kana zvasvika kune anoshanda maapplication, kusvika kune zvigadzirwa zveOPS (zvese-mu-mumwe muchina) zvine chekuita, ese SSD neHDD anogona kusangana zvakajairika kuchengetedza zvinodiwa. Kana iwe uchitevera nekukurumidza kumhanya uye kuita zvirinani, zvinokurudzirwa kuti usarudze SSD. Uye kana iwe uchida muchina webhajeti, HDD ingave yakakodzera.

Nyika yese iri digitizing, uye midhiya yekuchengetedza ndiyo ibwe rekona rekuchengetedza data, saka kukosha kwavo kunogona kufungidzirwa. Zvinotendwa kuti nekuvandudzwa kwetekinoroji, kuchave nekuwanda uye zvakanyanya-yemhando yepamusoro uye zvinodhura zvigadzirwa kuti zvizadzise zvinodiwa zviri nani. Kana iwe uine chero mibvunzo nezve kusarudza hard drive mhando, ndapota taura nesu!
