Izvo zvatove pachena kuti Raid tekinoroji ndiyo imwe yepfungwa huru pakubata nenyaya yekuchengetedza data nenzira yakachengeteka. Zvakare nekubudirira kwayo kwakaratidza, sezvo iri tekinoroji yakashandiswa kwemamwe makore uye inochengetedza huchokwadi hwayo nekuda kwekushanda kwayo.
Kune makambani makuru akawanda, akadai seIntel, anopa Raid mhinduro kana kusanganiswa kwavo, uye teknolojia iyi inogona kuwanikwa kunyange mumakombiyuta ekugara, kunyange zvazvo isingawanzoitiki, kunze kwezvikwata zvevashandi vanoziva nyaya yacho.
Nenzira yakadai, zvinokwanisika kuti Raid ichine nzira yakareba yekufamba, uye mumakore anotevera inofanira kuvandudza nemamwe mabasa, kuwedzera kushandiswa kwayo kune mamwe marudzi akasiyana-siyana ekuchengetedza zvinodiwa uye kuwana data.
Iva nechokwadi chekutarisa mazano anotevera, kana wapedza kuverenga Raid 0:
- Chirongwa chekudzima mafaira
- hardware features
- processor zvikamu
