I trying to figure out weather I have the right selection set for my motherboard In the Bios you can choose Native IDE Mode, Raid, or AHCI mode. I choose AHCI mode And installed Aventurine with 3ea 500gig with 16 meg buffers hard drives and choose software mirror on Aventurine install. According to this article I googled http://www.cyberciti.biz/tips/how-fast-is-linux-sata-hard-disk.html Linux kernel will recognize it and it does. I ran some tests and would be curious if someone else Could also run these tests on you BO box if your using Sata 300 drives. At the command prompt "#" These are the commands I run and the results I get # sudo hdparm -I /dev/sda | grep -i speed * SATA-I signaling speed (1.5Gb/s) * SATA-II signaling speed (3.0Gb/s) # sudo hdparm -I /dev/sdb | grep -i speed * SATA-I signaling speed (1.5Gb/s) * SATA-II signaling speed (3.0Gb/s) # sudo hdparm -I /dev/sdc | grep -i speed * SATA-I signaling speed (1.5Gb/s) * SATA-II signaling speed (3.0Gb/s) # sudo hdparm -tT /dev/sda /dev/sda: Timing cached reads: 5556 MB in 2.00 seconds = 2781.70 MB/sec Timing buffered disk reads: 340 MB in 3.01 seconds = 112.95 MB/sec sudo hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 5524 MB in 2.00 seconds = 2764.87 MB/sec Timing buffered disk reads: 358 MB in 3.06 seconds = 116.89 MB/sec sudo hdparm -tT /dev/sdc /dev/sdc: Timing cached reads: 5440 MB in 2.00 seconds = 2721.31 MB/sec Timing buffered disk reads: 324 MB in 3.02 seconds = 107.38 MB/sec I really am looking for comparison as I don't quite understand all the results. Any feed back would be appreciated David Kreifels _______________________________________________ Blueonyx mailing list [email protected] http://mail.blueonyx.it/mailman/listinfo/blueonyx _______________________________________________ Blueonyx mailing list [email protected] http://mail.blueonyx.it/mailman/listinfo/blueonyx
