With their 64 Gigabyte Synapse, OCZ has a neat little caching SSD in their portfolio. The thought behind these drives is that one can very easily upgrad a computer, where the operating system is installed on a standard hard drive. Therefore one only needs to attacht the drive to board and then install a software. The caching itself works in the background. On the following pages you'll see if it really is that simple.

Behind the scenes

Basically the OCZ Synapse is a 64 Gigabyte SSD, which uses a SandForce SF-2281 Controller and asynchronous NAND Flash memory from Micron. These have been manufactured using a 25 nanometer process and the individual chips have 29 F64G08CBAAA written on them. This indicates that the memory cells are specified for 3'000 P/E cycles and the memory itself is connected to the controller via ONFi 1.0 standard.
The caching itself is done by a caching solution from Dataplex. During the installation you can select your caching drive. In this case you take the OCZ Synapse. One the software is installed and the computer restarted, a background task will take care of the caching. The background caching process basically gets remembers the files you use most and puts them onto the caching drive to give you an improved user experience. As a user yourself you can't say which files you want to have cached or not.

Delivery

In the deliery you get what you need to setup the drive. There is a small manual, a serial number to download the Dataplex caching software, screws, a 3.5 inch mounting bracket and the SSD itself. Furthermore you find OCZs sticker on which it stands written: My SSD is faster than your HDD.
