hdparm -tT simultanous on /dev/hda3 and /dev/hdc3:
/dev/hda3:
Timing buffer-cache reads: 128 MB in 2.29 seconds = 55.90 MB/sec
Timing buffered disk reads: 64 MB in 4.67 seconds = 13.70 MB/sec
/dev/hdc3:
Timing buffer-cache reads: 128 MB in 2.28 seconds = 56.14 MB/sec
Timing buffered disk reads: 64 MB in 4.61 seconds = 13.88 MB/sec
Now on single HD - /dev/hda3 :
/dev/hda3:
Timing buffer-cache reads: 128 MB in 1.30 seconds = 98.46 MB/sec
Timing buffered disk reads: 64 MB in 2.26 seconds = 28.32 MB/sec
It looks like reading on /dev/hda3 locks /dev/hdc3 ...
Is it necessary to apply the ide-patches to the kernel ?
