i know they have threads for this already but all they ever said was "its how many input putput operations per second your ssd can handle" what exactly does that mean? what type of operations does this apply to?

Exactly what it says it is: the number of IO operations the drive is capable of completing per second.

If you try to perform 4KB operations on a drive that can handle 50k IOPS, then the bandwidth will be ~200MB/s and performance ends up limited by IOPS. If you take the same drive and use 64KB blocks instead, the performance ends up limited by interface bandwidth either on the PC or NAND side.

i see, that clears things up a bit, so how much bandwidth would an 850 evo be able to handle?
