OCZ Synapse 64GB Cache SSD $49 AR ($20 Rebate)

Read below. The worst idea for an SSD I've come across to date: of the 64Gb, your OS will only see ! 30Gb ! That's right, you'll only get 30Gb to play with, as the rest is reserved for over-provisioning. Besides, it's a non-TRIM drive. Here is an excerpt from an article on this product dated 05.12.2012:

Even when opened up and we looked inside, there is nothing you could point to and say “this is what separates a Synapse from an Agility 3 ”. As with the OCZ Agility 3, the Synapse relies on a single SandForce SF2281 controller and uses 16 ONFi 1 NAND chips. What makes this drive unique is not the NAND, nor controller but the firmware. In a typical 64GB SF2281 drive your operating system would see 60GB of space with the additional 4GB being set aside for over-provisioning whereas with the 64GB Synapse it is seen as a 30GB drive. Having this much over-provisioning is the very definition of overkill and has been done to help reduce the negative effects associated with running a SF2281 drive in a non-TRIM environment.

It is unfortunate that OCZ did not opt for Toggle Mode NAND or even ONFI 2.x NAND as that too would have helped obfuscate a degraded state better than what ONFi can accomplish. Given the price range this drive occupies and the philosophy behind it – i.e. budget price with enthusiast grade read performance– we understand the reasoning behind this move but like the plastic case, we do not consider this an optimal choice.
