Before doing anything drastic, go over everything.
(You know 5 minutes after u nuke the existing setup, the little lite will go on and you'll know what WAS wrong)

Check the basics, check ALL of the logs.
Sometimes there is one in the BIOS too.

Something very basic is wrong, maybe even a bad HD.

Did you use the RAID setup to format the HDs ??

Just asking ?s maybe one will click, and you'll see the error.

I don't recommend RAID for home users, no real benefit. Backups provide almost as much protection with 1/10 the cost, headaches and hassles.
And you MUST have them anyhow.

RAID 5 will slow down read/write, but it shouldn't be enough for you to notice.
