So I currently own a Kingston V300 120GB which is advertised at:
450MB/s Read
450MB/s Write

But the thing is, my scores seem higher:

I'm considering buying a Samsung 840 Pro 256GB and it says the speeds are:
540 MB/s Read
520 MB/s Write

Should I expect to exceed the Samsung listed specifications too?

While the Samsung is a better drive and is larger, which also helps, you will not really notice much real world difference. Don't expect to exceed specifications with benchmarks.

My idea is to replace my 120GB with the 256GB as the OS drive. I will put games on the 120GB and use the 256 for OS+Programs/downloads and other miscellaneous things.

I want the OS drive to be real reliable and I hear that the 840 pro is just that.

I was going to go with the 240GB version of the V300 or the HyperX 3K, but I noticed that the 840 pro isn't much more now.. and since I'm paying for it why not get the better one for $50 more?

The reason I asked about exceeding the posted speeds is because the V300 exceeds them on my PC. Any idea why that's happening? Do the SSDs just vary or something?

It looks like your drive is close to the one reviewed HERE and they say the high scores are due to the compressible data used in the ATTO benchmarks.

Ah interesting. Here's a test with AS SSD. I've heard having 20% or more free space is a good idea on SSDs but right now mine is pretty full. I have 3GB left on it. Anyway here it is:

So would that mean that it's actually under-performing?

Yeah, but with only 3GB empty space that would not be unusual.

Alright I freed up space and have 25.3GB free of the 111GB capacity.
