I also had a rash of 500 G SATA drives fail I lost 4 out of 12 in the first
month, and 2 more since I went into production. I think the Maxtor drives they
were using are no longer being sold, and the replacements have been rock solid
for over a year. The Adaptec SATA raid controllers have been nothing but
junk, but it is probably also related to the Maxtor drives. I will never buy
anything but 3ware SATA unless they mess with EXT2/3 again.
