Behind the scenes

With the XLR8 Express 120 Gigabyte, Extrememory has an SATA-III SSD in its portfolio that is based on the latest SandForce SF-2281 controller and makes use of synchronous NAND Flash. This has the consequence that you will get as much performance out of the controller as possible. On the other hand the synchronous NAND flash is more expensive then asynchronous memory chips. In the case of the XLR8 Express 120 Gigabyte Extrememory uses Toggle NAND Flash which has been manufactured by Toshiba and comes with 25 nanometer structures. On the 120 Gigabyte drive there are eight ICs whereas each offers 16 Gigabyte storing capacity. The exact identification number is: TH58TAG6D2FBA49.


The test sample that reached our office arrived in a very small box. As you'd already expect from a first look the there is only a 2.5-to-3.5-inch adapter bracket included in the delivery. You wont find any cloning software like for example Acronis Disk Image or Norton Ghost.
