A few months ago I had an enormous amount of grief trying to understand why a RAID array in a new server kept getting corrupted and suddenly changing configuration. After a lot of despair and head scratching it turned out to be the SATA cables. This was a rack server from Asus with a SATA backplane. The cables, made by Foxconn, came pre-installed.
After I replaced the SATA cables with new ones, all problems were gone and the array is now rock solid.
Thanks for this info, Miguel. <snip>
As an additional information, I quote from the Caviar Black range datasheet:
"Desktop / Consumer RAID Environments - WD Caviar Black Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 /RAID-1).
- Business Critical RAID Environments WD Caviar Black Hard Drives are
not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WDs Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing."
Wonderful... NOT. We've got a number of Caviar Green, so I looked up its datasheet... and it says the same.
That rebuild of my system at home? I think I'll look at commercial grade drives....
