If you buy a machine with an SSD installed inside of it there is a good chance it is from Toshiba and it might even be the THNSNH 256GB model.  As these drives are not sold separately but only inside OEM machines it is not often benchmarked.  [H]ard|OCP wants to change that and put this drive and its internally designed controller up against some of their favourite retail drives.  Their testing revealed a mixed bag of performance as in some tests it came close to beating out Samsung's 840 series but in other testing ended up at the bottom of the pack.  Still, as this drive will end up in many mobile devices it is good to get an idea of the performance you can expect from it.

"Toshiba's massive foundry capabilities allow it to develop some of the leading SSDs for the OEM market. These SSDs come pre-installed in the latest computers with the option for an SSD, and today we look at the Toshiba THNSNH in comparison to current top-flight enthusiast-class SSDs."
