IsOK readable b
</pre>
<p>
</p>
<p>
Whether this drive is read and writeable without any error or warnings.
It's the single preliminary check on whether things go wrong.
Noted: even from user's view, RAID degrade does not cause any
error or warning at OS level, the 'isOK' property will still be set
as 'FALSE' to suggest user to do more checking on what's going on.

The minimum I/O size, device preferred I/O size for random I/O.
Any I/O size not equal to a multiple of this value may get
significant speed penalty. Normally it refers to strip size of
each RAID disk(extent). If LibStorageMgmt failed to detect min_io_size,
it will try these values in the sequence of:
logical sector size -> physical sector size -> 0
