That gives: Timing cached reads: 1348 MB in 2.01 seconds = 671.75 MB/sec Timing buffered disk reads: 164 MB in 3.00 seconds = 54.64 MB/sec Same udma5.

That disk is 6 months old! So I am going to get rid of the Samsung and get something else. H -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
