mSATA SSDs review: Adata XPG SX300 128GB vs Crucial m4 256GB
 

We were kind of expecting it, but it's nice to see concrete proof that mSATA SSDs are as fast as their 2.5-inch counterparts, despite their small size. The Adata SX300 128GB scores almost exactly the same in every benchmark as the Adata SX900 128GB that is based on the same controller. The Crucial m4 256GB mSATA performs the same as the standard m4 256GB.
