Intel RAID0 on Windows 8 not Displaying Correct Media Type
According to Intel's website, TRIM is not supported for any RAID configurations at the moment:
TRIM support in Windows 7 [and 8] (in AHCI and RAID mode [only] for drives not part of a RAID volume)
Source: http://www.intel.com/support/chipsets/imsm/sb/cs-022304.htm
That page is dated 04-Oct-2012, so pretty recent, too. Their latest SSD Toolbox FAQ supports this stance as well (see Q11).
Of course, Intel being Intel, this appears to be completely wrong, and they DO support TRIM in RAID 0 configurations (but only for 7 Series chipsets).
RST 11.2 supports TRIM on RAID 0 only on Intel Desktop Boards with the 7 Series chipsets.

And the following Anatech article details support for TRIM support in RAID 0:
The feature is limited to Intel 7 series chipsets with RST RAID support and currently only works on Windows 7 OSes, although Windows 8 support is forthcoming.

So it IS supported. Just not by Windows 8 at the moment.
Update: It appears Windows 8 RAID 0 TRIM is supported as of RST version 11.6.0.1030. Just make sure you install all the Windows 8 Updates before you unstall RST.
Good luck!
This died upgrading to Windows 8.1 for me.
The problem is caused by Microsoft WEI (Windows Experience Index) not being run (its even removed from the GUI in Windows 8.1).
To help Windows 8 and Windows 8.1 users, the core code that does this is still in Windows, but only accessible from the command line in 8.1.
To get the SSDs to be correctly listed:
1) Install the latest RST from Intel (currently 12.8 from Aug'13). 2) Go to an admin cmd prompt 3) Type: winsat prepop
This will run all the tests on the computer and reprofile it. This includes correctly tagging RAID0 SSDs.
Took me ages to find out how to fix this. Well worth sharing with everyone.
If you're keen you can limit the testing to just the disk, but why bother? Best get the whole computer back on track.
