I found my actual results from a WD consumer 320GB drive (single platter) with the drive on the bench vs inside a 1U node:

My best guess is that is not uncommon, and when I manage to pry a decent spec sheet out of vendor they do show dramatically different vibration specifications. So while I encourage folks to try the 2TB WD consumer drive in a 48 drive array and report back, my expectations are low. Personally I'll wait, I'm sure both Seagate and WD will ship over 1TB raid editions at some point. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
