'flush cache' just needs to make sure that data has been flushed from any
volatile location to non-volatile.
If the drive is not spinning, 'flush cache' should not be required to copy
the data
from non-volatile cache to rotating media. That would negate the power
savings
that is being achieved.
Besides, a NVCache drive is a 'black box'.
It shouldn't matter to the host at all because the non-volatile cache and
rotating media cannot be separated from each other.
The drive guarantees that the data is non-volatile after a flush. That's
what really matters.
Thank You !!!

No Phone Info [t13] Flush behavior on a Hybrid
Available disk

Hi All,
So my last question got such a resounding reply (none) that I figured I'd
try another question.
On a hybrid disk that has it's volatile write cache enabled and has been
written to, when a flush command is received is the disk obligated to flush
all the way to the rotating media, or is it sufficient to flush to any
non-volatile medium (flash)?
Thanks, MKE.
