Neither do we :( Whereas I have 28 7Y250M0 drives sitting in a couple of arrays here that have behaved perfectly (aside from some grown defects) for over 18000 hours so far. They are *all* sitting on Promise SATA150TX4 cards on 2.6 kernels. I'm looking at another server and another 15 drives at the moment, and it's Maxtors I'm looking at. Everyone has different experience. I would not touch Seagate with a 10 foot pole (blew up way too many logic boards when I was using them), and I got bitten *badly* by the WD firmware issue with RAID (firmware upgrade fixed that, but can't replace the data I lost when 3 of them failed at the same time and the array got corrupted). Having said that, it was MaxLineIII 300G drives I was looking at, so perhaps I'll wait a little longer and hear some more stories before I drop $$ on 15 of them.
