Windows 8.1 seeing SSD "T" disk on RAID channel 5 &6 as HDD

[Ambidexter]

Hi,

I've seen numerous posts on Win8.1 not seeing system SSD disks, especially in RAID configurations. My problem is a bit different. I have the following config:

C:\ = RAID 1 SSD - 2 X Samsung 840 PRO Port 1 & 2 on RAID ctrlr (256 GB Total storage)
D:\ = RAID 1 HDD - 2 X Hitachi 7K4000 Port 3 & 4 on RAID ctrlr (4 TB total storage)
T:\ = RAID 0 SSD - 2 X Samsung 840 PRO Port 5 & 6 on RAID ctrlr (512 GB total)

I am using windows 8.1 on an Asus Maximus VI Formula board with an Intel 4770K processor and 32 GB of Munchkin Redline memory.

Windows correctly sees C:\ as an SDD and D:\ as an HDD, and will optimize each properly (i.e. trim and defrag).

Windows sees the T:\ disk as an HDD too, and optimize here will try to defrag the SDD. Not a good idea, so I turned off auto optimize.

Additionally, I'd think the T:\ disk works better as several trim-aware utilities tell me the trim feature doesn't work on the C:\ disk...even though windows seems to do the trim when optimizing the disk. But these same utilities DO notice the T disk will trim...it's just Windows thinks it's an HDD.

No number of WEI runs will make this disk be seen as an SSD...what I can do to get this to go? Do I need to move around the disks on the RAID adapter (internal Intel) or change the volume's disk letter?

Thanks,

P.S. I have re-installed Win 8.0 and upgraded to 8.1 when we discovered the UEFI partitions were goofed up by the upgrade, so I'm over that issue anyway!

Which controllers have you used for the T drive?

All 6 are on the Intel ports. None are on the other controller...except I do have the DVD on the non-Intel, because a) I needed the 6 Intel ports and b) it won't boot with RAID on any of the first 6 and the DVD also on one of the first 6.

Thanks,
