I-ThunderBay 4 isekela amaDay Dri Hard, SSD, RAID, ne-Non-RAID kunoma iyiphi i-Combo
I-OWC (Okunye i-World Computing) sekuyisikhathi eside isendaweni yokuya ezindaweni ezihlobene ne-Mac, ngakho-ke ngenkathi inkampani iqalile ukukhiqiza izingqimba zayo zangaphandle ezixhaswe ngeThunderbolt, nginentshisekelo yami.
I-Thunderbolt ibe yingxenye yamakhono we-Mac O / O kusukela ekuqaleni kuka- 2011 , futhi manje ingxenye yazo zonke izinhlobo ze-Mac zamanje. Isithembiso saso esikhulu kwakuwukuhlinzeka uhlelo lokuxhuma okusheshayo phakathi kwamadivayisi angaphandle kanye ne-Mac, kodwa ngaphandle kokuboniswa kwe-Apple Thunderbolt, kanye nokuhambisa okuncane kwe-Thunderbolt yangaphandle kokulungiselelwa kwe-RAID, akuzange kube khona amadivayisi amaningi we-Thunderbolt.
Sibutsetelo: OWC ThunderBay 4
I-ThunderBay 4 iyindawo engaphandle ye-RAID Thunderbolt engavumelana ne-four standard driy drives noma ama-SSD amane (i-adapter ethengiswa ngokwehlukana), noma yinoma yikuphi ukuhlanganiswa kwezinhlobo ezimbili zokushayela.
Ngenxa yokuthi i-enclosure ayihlanganisi i-RAID esekelwe ihadiwe langaphakathi, i-Mac ibona imishini efakwe endaweni evulekile njengamashayeli angaphandle, okuvumela ukuthi unqume ukuthi izokwenziwa kanjani. Bangakwazi ukuhlala njengamashayeli athile, noma ungasebenzisa enye yezinhlelo ze- RAID ezisekelwe kwesofthiwe, njenge-Apple Disk Utility noma i- SoftRAID . Sizoxoxa kabanzi mayelana nokukwazi ukuphakama kwe-RAID ngemuva kwesikhashana kulokhu kubuyekezwa.
