Was looking at a RAID 5 system but after reading more, found that RAID 1+0 is better. RAID 1+0: mirrored sets in a striped set (minimum two disks but more commonly four disks to take advantage of speed benefits; even number of disks) provides fault tolerance and improved performance but increases complexity. The key difference from RAID 0+1 is that RAID 1+0 creates a striped set from a series of mirrored drives. In a failed disk situation, RAID 1+0 performs better because all the remaining disks continue to be used. The array can sustain multiple drive losses so long as no mirror loses all its drives.[6] When reviewing RAID 5, I found it is better to go to RAID 6. Sort of in the camp, that if you make a mistake taking the wrong drive out with 5, you blow the entire raid. But with raid 6, you won't lose the raid. Was considering doing a software raid system ... But as you can see above RAID 1+0 offers some good advantages. Currently my Vantec box is RAID 1 - working well so far.

I have Raid 1 on XP with 2 hard drives installed, and after using that computer for two years have no clue as to all of the benefits of Raid 1. I think it mirrors every key stroke (including viruses), and would probably be very useful in the event of a hard drive failure. At one point I called Dell support to undo Raid and just have the extra drive, but they advised against it. All of the Raid Google searches I have done over the years reveals much contradictory information and opinions.
