Ake sihlole lokho okushiwo yinkulumo eside, okungukuthi, phezu iminwe, ngesisekelo ulwazi incazelo isakhamuzi isilinganiso.

Yiziphi disk afanayo raid?

Ukuze uqale, cabanga ukwelashwa jikelele olunikezwayo zincwadi kuyi-Internet. Idiski afanayo - lokulondoloza uhlelo lonke, ehlanganisa isixha oshayelayo emibili noma ngaphezulu kanzima, abasebenzi, noma ukwandisa ijubane lokufinyelela ulwazi egciniwe, noma ngenxa ukuphindwa, isibonelo, lapho ulondoloza amakhophi agade ingozi.

Kulesi lemali ngokuhlangana ushayela ngokuya ukufakwa kwakuthiwa engenayo imingcele. Konke kuncike inani ukuxhumana osekelwa umbadlana. Empeleni, kungani asetshenziswa disk afanayo raid?

D.). Wenza okuhlukile kulokhu SSD onobuhle kuphela, kodwa ukwandisa kuphela umthamo ekhiqizwa ikakhulu. Ngesikhathi esifanayo emsebenzini wokukhiqiza izilimi noma RAM kwamapulangwe bathuthuke obuphathekayo. Ngakho, ngokusebenzisa raid-afanayo wenziwa ukwanda ukusebenza ukukhula lapho ufinyelela hard disk oshayelayo.

Idiski afanayo raid: izinhlobo, injongo

Raid 2 nangaphezulu

Afanayo ngezinombolo 2 nangaphezulu kukhona injongo esikabili. Ngakolunye uhlangothi, ziklanyelwe balobe ukwaziswa ngakolunye - esetshenziselwa ukulungisa iphutha.

Ngamanye amazwi, lolu hlobo isitoreji afanayo ukuhlanganisa amakhono raid 0 futhi raid 1, kodwa abasebenzisi phakathi kwekhompyutha abakujabuleli ukwanda okukhulu, nakuba isisekelo somsebenzi yabo ukusetshenziswa ikhodi Hamming.

Yini kungcono ukusebenzisa in practice?
