SSD array flagged dirty

[Mr Snoot]

Multi-boot XPPROSP3, XPSP364BIT, Windows 764BIT. 7 is on an 120GB SSD RAID0
array all by itself. XP OSs are on seperate partitions on a conventional, 4
drive RAID0 array. MB BIOS, ICH9R, SSD Firmware are all the latest.
System/RAID drivers are Intel's latest batch.

Every once in a while when booting into XP (I only use Windows 7 for the
media center because thats all its good for), checkdsk runs on the SSD array
and then I have to boot 7, let chckdsk run, then everything is ok for a
while. Chkdsk never finds any problem.

Hardware is fairly recent stuff, 775w thermaltake PS, 8GBs DDR31600MHz ram
at 1688MHz 7.1v, X48 chipset, Q9550 CPU at 3.6GHz, 1.41V Had some stability
issues getting a stable Overclock but everything is stress tested and stable
except for that checkdsk thing

It's not unheard of.

One problem with any storage device, is proper flushing of all levels
of caching, before the OS shuts down. Long ago, there were problems,
where you could shut down a computer from the Windows menu, only to find
that the last committed file was lost. And that implies that some cache
(OS write cache, storage device internal cache etc), wasn't getting
flushed to the media. At that time, the fix was to add a delay to
shutdown (on the assumption that, indeed, the appropriate command
had been issued, but it was a timing problem - the command didn't
complete before the power went off).

Now, my recollection is a little too fuzzy to help you, but
I seem to remember at least a couple versions of Intel RST
RAID driver had issues. Find the release number of your
RST driver, and do some googling. You might get some hits in
the communities.intel.com site, where customers complain
about their RST supporting TRIM, degrading the array at random
and so on.

Alternately, post bad with the RST release number, and the
make/model/firmware version of each of your SSDs. Maybe someone
will find something, based on your particular combo.
