You could/should be using LVM instead of partitions, IMHO. > Anyway, any storage advices for performance? Unfortunately, no. I have seen similar things happen. I think that the problem is Linux I/O. Your drive may be able to handle high, sustained read/write rates, but the Linux I/O scheduler, in combination with random-access reads/writes, makes these performance data inaccurate. The only way I found to decently increase performance of drives: - 10k and 15k drives - external NAS or fibrechannel SAN, which do not use Linux Yes, it's sad, and I would love to be proven wrong! -- martin | http://madduck.net/ | http://two.sentenc.es/ "if java had true garbage collection, most programs would delete themselves upon execution." -- robert sewell spamtraps: madduck.bogus@xxxxxxxxxxx
