The first mSATA-based SSDs we reviewed wowed us with diminutive dimensions, but not as much with performance. Today's best efforts are a lot more like their desktop equivalents, though. We round up 10 models between 64 and 256 GB and nail down a winner.
Test Setup And Benchmarks
Although we see Ultrabooks (and other thin and light form factors) as the most likely beneficiaries of mSATA space savings, they don't make great benchmarking platforms for swapping drives in and out. So, we're using an mSATA-to-SATA adapter on our desktop test bed. There is no performance penalty associated with this configuration, since the adapter simply changes the physical interface, not the signaling. As a side benefit, this setup lets us compare mSATA-based drives to larger 2.5" SATA-based SSDs without introducing any other variables.
