I just had two 300GB drives fail in a 2TB RAID5 setup. Luckily, it was a fairly new (<6 months) device, so I had replacements in hand pretty darn quick. Rebuilding the database that lived on them, though... time-consuming (if you ever have to build a 700GB MySQL database from .sql files, be prepared to wait). My gut tells me that, if one drive in a new-ish device fails, the likelihood of a second failing at-or-near the same time is pretty high, as the drives themselves are likely to be from the same manufacturing batch. -- D ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
