840 EVO  vs Crucial M500 

The RAPID mode is designed specifically to help boost random performance and uses spare CPU power and system memory capacity (up to 1GB) to act as another layer of cache.

I hope you went with the 840 evo. Samsung has a software that can control the SSD and they have this Turbo mode and makes the SSD as fast as PCI SSD
I am currently looking between those two SSD Drives, but can't decide what's the best choice (MLC vs TLC). For more data security MLC would be better because of the higher amount of read/write actions each sector can handle, (2 bit vs 3 bit). But at the other hand, the EVO will last so long before you get bad sectors that even with high data transfers it will take years and years before you even lose files and so on. Hard too choose lol......
