Corsair P256

If you remember back to January of this year, Corsair quietly launched a 128GB SSD. Like that drive, the recently released P256 model features Samsung technology, but with a new controller and integrated cache that should offer significantly increased performance.

The drive you see here is branded as a Corsair S256, but the official name of the product, now that it has hits store shelves, is P256--the "S" was changed to a "P". As the product name implies, the drive features a 256GB total capacity, with SATA 3.0Gb/s connectivity, and a heavy-duty aluminum enclosure.

With the P256 disassembled, you can see the PCB and new Samsung S3C29RBB01-YK40 controller used in the drive as well as the drive's 128MB of on-board cache memory. As you can probably guess, Samsung MLC flash memory is also used in the drive, and if you look close, you can see that the memory chips are double-stacked to acheive the 256GB capacity.
