Hi,
If you use WD Velociraptors in RAID and run them 24/7, and you get occasional failures where they drop out of RAID, yet rebuild fine with no loss of data, then you may be interested in this thread:
http://forums.storagereview.net/index.php?showtopic=27303&st=50
So... there's a bug in the TLER code in the firmware that causes errors after 49 days of continous operation. I was faily sure that my problems with Velociraptors were down to the RAID controllers I've used them with (Areca 1680ix and Dell PERC 6i) - but it turns out that the drive firmware is to blame. Obviously the defnition of "Enterprise drive" varies, but I'd have thought that more than 50 days of continous operation would have been one of the criteria...
But! New 04.04v02 firmware fixes the bug!
However... the 04.04v02 firmware is not available on the WD website, and 1st level support claimed that if it wasn't on the website, it didn't exist... I've escalated to 2nd level support and they claim that they're unaware of the issue etc etc. Hopefully a bit more pushing and they will release it to me, but I would rather that they posted it publicly.
After struggling for months with Velociraptors, I was ready to give up and pay the extra for more SAS drives - but this new firmware may make me stay their execution.
cheers,
Aitor
