Building a mini itx gaming system, would prefer to use mSata over Sata but not at a significant performance loss. The drive will be the only system drive, there are the two I'm trying to decide between:
Crucial M500 240GB SATA mSATA Internal Solid State Drive CT240M500SSD3
or
Kingston SSDNow V300 Series SV300S37A/240G 2.5" 240GB SATA III Internal Solid State Drive (SSD)

The speeds look comparable:
Max Sequential Read
Up to 500MB/s
Max Sequential Write
Up to 250MB/s
4KB Random Read
Up to 72,000 IOPS
4KB Random Write
Up to 60,000 IOPS
MTBF
1,200,000 hours

vs

Max Sequential Read
Up to 450 MB/s
Max Sequential Write
Up to 450 MB/s
4KB Random Read
Up to 85,000 IOPS
4KB Random Write
Up to 43,000 IOPS
MTBF
1,000,000 hours

my tentative build as of now:

The mSata drive is $10 more, so price really isn't a factor. Is there some other consideration I'm missing here or are they going to preform similarly?
 
Solution
That's a half-length mPCIe slot. Physically the connector is identical, electrically it's different. It's too small for an SSD and not wired right.

There's a full-length combination mPCIe + mSATA slot on the underside of the board.

compressible data handling by SF-2281 is good enough. I agree that SF seems to have minor glitches in handling incompressible stuff. I had specifically purchased this controller for tackling compressible data & also to test write speeds on this data and I must say I am not disappointed by their performance. Only thing that strikes, if others are having issues could be to check if they are using the latest firmwares from their vendors.
 
It's not glitches though; it's a fundamental part of how they're designed.

Besides, the largest files most people move around are already-compressed video, and large quantities of JPEG/PNG/GIF images, which are also compressed.

And if you're using any form of encryption, well encrypted data is also incompressible.
