I have many to sell.
Can you be more specific as to what you are looking for?
I think he's being pretty concise. He's buying any 2.5" SDD >40GB with an Intel/Indilinx/Sandforce controller that doesn't utilizes 25nm NAND.
There's a LOT of those though. It could also be a samsung or marvel controller as well, those are quote a bit better performance then the indilinx ones. Seems he doesn't have any particular one in mind but about 80% would meet most if not all of those qualifications. If he's looking for suggestions pretty much any semi modern SSD should do fine. It would be EXTREMELY hard to tell the difference between the any of the modern ones except in synthetic benchmarks. Only problem is there might not be a whole lot of a difference in price between an old vertex 120GB and a vertex 2 or 3 with first and second gen sandforce ones.
