ATTO R680 + SOHOTANK ST8-U5 + Seagate ST33000651AS = ISSUES!

I've built an 8-drive array with the above components, and striped it RAID 5.

In a week of operation, I've had 3 different drives "degrade". In one instance, I sent the drive back for a replacement. In the second instance, I pulled the drive out, put the *same* drive back in, and ATTO config tool said "Status: OK". Rebuilt RAID successfully.

Now, it's happened a third time. Again, I pulled out the offending drive, put same drive back in and "Status: OK".

Are the Seagates *so* bad that I get 3 true failures inside a week?! Or, is there some other possible explanation that ATTO is seeing drives as "degraded" that really aren't?

Thanks in advance...
