( ide: seagate, ibm, fujitsu, wd, maxtor, quantum ... ide disks are warranteed for 1,3 or 5 years and some have a 1,000,000 MTBF ... what you do to it to destroy the mtbf is what makes the difference of how long it will in fact last in your environment and most of my ide disks are approaching 8-10 years and no problems though most of the cpu's or mb have long since been offline for too slow of a cpu -- most all are in offices or 65F server rooms how you build systems does make a difference.. - lots of fans ( at least 2 per ide disk, just in case one dies ) ( that is the same as with scsi .. now you can compare ) > A expensive vendor doesn't help you from crappy HW insealf. lots ... 90% f crappy vendors ... - bad disk or wrong disks - bad mb or wrong mb - bad nic or wrong nic - or no rma number to return bad parts - .. on and on .. - i buy thru tier1 distributors and don't have any "noticeable" bad parts ( maybe .1% failure ( doa )) over 1,000s of ide disks in the past year or two and lasts way past its warranty period == == everybody has their good and bad ideas of what are good disks and not == and does not mean that otehrs should expect the same problem == when everybody buys disks from different vendors and definitely == installed differently ( no redundant fans to cool 7200rpm ide disks ) == operating temp on ide disks should be 25-30C or less per "hddtemp" == c ya alvin - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
