What format are the tracks in?  16 bit, 44.1Khz is 0.7MB/sec per track

which any drive

should be able to handle 10 tracks of.  But with 96Khz and 24 or 32

bit samples, you

could be pushing the limits of the drive.
What does running hdparm -Tt on the block device (/dev/sdX) give you?
Realtime tuning should not matter because with any sanely written DAW the disk

IO will be done in it's own non-RT thread.
