OCZ Synapse Cache 64GB Solid State Drive

Looking inside of the Synapse Cache drive, the configuration used is very similar (if not the same) as OCZ's Agility line of SSDs.  LSI SandForce's SF-2281 SSD controller is used in conjunction with asynchronous NAND from Micron.  There are eight NAND modules of 8GiB each, totaling 64GiB of capacity.  Each module has one die, so there is one die per SF-2281 flash channel.  As we found in our other SSD reviews, having more dies per flash channel helps to increase read/write performance with high queue depths and small page sizes.  Typically, smaller SSDs are constrained in this regard to a 1:1 ratio (dies:channels), while we've seen larger SSDs with up to a 4:1 ratio.  Regardless, the Synapse drive will still be signficantly faster than the traditional hard drive for which it will serve as a caching platform.

The other side of the PCB in the Synapse Cache drive is blank.
