In years past, we worried about testing Samsung's smaller capacity SSDs, and I think Samsung worried about what we would come up with as well. Before RAPID, the smaller capacity drives with lower interleaving levels between the flash and the controller were an issue. RAPID (and to a smaller extent, Turbo Write) alleviated the issue. To put it in simple terms: the lower capacity Samsung SSDs are pretty good now.
When it comes to reading data from the drives, the 840 EVO mSATA products are leading the market. The EVO products are positioned as consumer SSDs, so most of these drives will end up in soccer mom Ultrabooks, or business notebooks/Ultrabooks. That's not really a bad place to be and with the new eDrive, and TCG Opal support. Business users can increase productivity, while still staying within company security policies, and if needed, it's even HIPPA compliant.
With the performance and feature set covered, that only leaves availability and the price. At the time of writing, the mSATA versions of EVO were not at any of the e-tailers we checked. Samsung expects e-tail availability just after CES, or the second week of January. The launch day MSRPs are very close to the 2.5" EVO products, so we expect discount e-tailers like Newegg, Tiger Direct, and so on to take a hit on margins, and put MSRPs in the rear view as early as a week after the launch.
The Samsung 840 EVO mSATA 120GB is a cost effective way to install best in class performance for a new Ultrabook. RAPID Mode, part of the free Magician software suite, does a good job of fixing any write latency issues, and leaves us with a great all around performer. While we don't talk about it much, Samsung's Data Migration software (also a free add-on) is a great way for mainstream users to clone an existing drive without a lot of technical knowledge. In this case though, you would need to do so without the aid of a USB adapter.
