TWO TERABYTE LIMIT -- FIXED
I did some follow-up on the 2TB limit. I tried again with eight 500GB drives. The RocketRAID 2220's RAID manager sees the full 4TB (3.5TB formatted). But Apple's Disk Utility can't see more than 2TB. Why? Because the firmware based RAID 0 set is presented to the Disk Utility as a single virtual 4TB drive. And OS X can't handle a physical drive large than 2TB.

這個人用500GB*8來架RAID0
用HIGHPOINT RocketRAID 2220
看得到全部硬碟
