My guess is that your disks are are not idle long enough.
In a text window if you look with "lsof" you can see a list of
open files in the system. A Linux system can have a lot going on
in the background. If you run the command "sar -d 5 5" you will
see measures of disk activity.
I suspect the output of sar will show low but non zero disk IO.

-d Report activity for each block device (kernels 2.4 and later
only). When data is displayed, the device specification dev m-n
is generally used ( DEV column). m is the major number of the
device, whereas n is a distinctive number.
tps
Indicate the number of transfers per second that were
issued to the device. Multiple logical requests can be
combined into a single I/O request to the device. A
transfer is of indeterminate size.
sect/s
Number of sectors transferred from or to the device. The
size of a sector is 512 bytes.
