Default Re: nForce 3 SATA vs Silicon Image SATA

Now having two Hitachi 250 GB SATA drives and kernel 2.6.8-rc2,
I can test both SATA controllers at the same time.

sda is on the nv controller, sdb on the sil. These numbers suggest
the performance difference is negligable.

Code:
[root@rubens scsi]# hdparm -Tt /dev/sda
 
/dev/sda:
 Timing buffer-cache reads:   3024 MB in  2.00 seconds = 1511.47 MB/sec
 Timing buffered disk reads:  176 MB in  3.01 seconds =  58.54 MB/sec
[root@rubens scsi]# hdparm -Tt /dev/sda
 
/dev/sda:
 Timing buffer-cache reads:   2984 MB in  2.00 seconds = 1491.48 MB/sec
 Timing buffered disk reads:  176 MB in  3.00 seconds =  58.58 MB/sec
[root@rubens scsi]# hdparm -Tt /dev/sdb
 
/dev/sdb:
 Timing buffer-cache reads:   2980 MB in  2.00 seconds = 1488.74 MB/sec
 Timing buffered disk reads:  176 MB in  3.03 seconds =  58.00 MB/sec
[root@rubens scsi]# hdparm -Tt /dev/sdb
 
/dev/sdb:
 Timing buffer-cache reads:   2940 MB in  2.00 seconds = 1469.49 MB/sec
 Timing buffered disk reads:  174 MB in  3.00 seconds =  57.99 MB/sec
