It's a mechanical property- vibration tolerance and whatnot.

I have 5 400GB RE2 drives in a RAID5 array (software raid, naturally). That 5 year warranty has come in handy- only 1 of the original drives still remains. 5 RMAs in under 3 years. Maybe the 500GB is better. -- Brendan Conoboy / Red Hat, Inc. / blc@redhat.com
