Dissection
First off, be aware that this is not a recommended procedure. At best you kill your drive’s warranty. At worse you kill your drive. There is no reason for an end user to crack their drive open like this.
With that out of the way, here’s one of the flash chips OCZ used:
Intel flash is good stuff. This is a 25nm MLC chip.
How about a controller shot?
SF2282 controller, from what I’ve read it’s built for big drives, like over half a terabyte. What it’s doing in here I don’t know, but I’m certainly not going to complain!
Ok ok, some full PCB shots:
Well now that explains some things, there are a lot of flash chips in here. More chips in parallel means the controller can play more games with them for better performance. It also means that lower capacity, less expensive, flash chips can be used. This drive has 16 chips, the same as the Vertex 3 240GB MaxIOPS and Revodrive3 120GB, but unlike the former it has room for 32 of the things! That’s wild.
