Slightly off-opic

Re: Hard drive reliability

The site I support utilizes Intel Paragon supercomputers, with each one housing 50 Seagate 4 GByte SCSI disks (in 10 level-3 RAIDs with 5 disk per RAID). These disks are POUNDED 24 hours a day solving very large systems of linear equations. I would estimate that they are receiving 1000x more reads/writes than an average desktop disk (maybe less for a server). They are quite reliable, though they do occasionally fail. Sometimes they can be reconstructed using the RAID-3's parity and put back in service, other times they are completely dead. Don't know much about price, however. Personally, if I had an NT system with important data, I'd opt for RAID level 1 (mirroring) using disk duplexing, especially with the decline in disk prices.
