Windows 7 supports TRIM for an individual SSD, but does it work with two SSDs merged together as a Spanned Dynamic Disk?

"Dynamic Disk" is Microsoft's proprietary version of LVM.
The equivalent feature for Linux was added in kernel 2.6.37.

Related (deals with a spanned volume using an HDD and SSD): Will Trim still work if creating a spanned volume of two disks. Also somewhat related: Is TRIM supported on RAID 0 configurations for SSD drives in Windows 7?. As for spanning, most on this thread say Trim is not supported. –  Karan Dec 17 '12 at 0:53
