Wiser folks than me have chimed in, but I wanted to add an anecdote... I used to use bargain power supplies on all my systems. These are the 400W that come with the $30 cases I used. On my cluster of about 10 nodes with 2 drives each, I was sending back a drive every month. Failure rate was about 5% every month, in other words. Since upgrading all my power supplies to warrantied, name brand units (mostly Antec, but others also), I have had 2 failures in 2 years. I looked at the purchase history and saw that for a long while I was buying Maxtor and Western Digital drives, then switched to Seagate but the failure rates were about equal for all manufacturers. This is not scientific data, of course, but it convinced me that the power supplies had a greater impact on drive failure than anything else. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
