this looks indeed pretty slow, is it an external usb-2 drive?
You may perform a simple check:

sudo hdparm -tT /dev/sda

Replace sda with your device.

If your are just recording, can you increase the buffer length in jack?
I was recently recording 32 mono channels  and got initially lots of xruns in ardour,
which disappeared after increasing the buffer size in jack.

Best regards,
Peter
