Too many SSD beginners get impressed by the big numbers. But what you usually see are sequential transfer times of large blocks. However, for the OS those are completely irrelevant. The numbers to focus on are access time and 4K random R/W speeds because that's what the OS uses most of the time.

A good SSD that is suitable for the OS should have an access time around 0.1ms (as measured with AS SSD) and a 4K transfer time around 100MB/sec (as measured with Atto).

In your opinion what is a good SSD with these spec in a 256 drive that isn't the cost of a Samsung 840 Pro ? Since as you mentioned in another post in my situation, I'd be better with a 3 GB over a 6.

Here's a list in no particular order Chris.

Here are a couple. I own both a Mushkin and a Crucial M4 and am very happy with those.

Now I have had a look and can someone tell me the difference between the 840 Pro and the straight 840 apart from the price and that it seems to me the Pro has a very slight speed increase over the plain variety?

As for the comment by Johnny Cash I am using the SanDisk Extreme in my laptop and it has a Sandforce controller and it like I said before leaves my 830 in the blocks on boot up and I think even between apps tabs etc Mind you I do have 8 on it!

My supplier at the moment Solid State Drives (SSD) really does limit me to a few brands unlike what everyone else has got. So I cannot try the OCZ or Crucial right now as they used to carry them but not now. If you are wondering they are about the best priced site over here some are cheaper but very suspect.

The "cellular" architecture is the biggest difference. The 840 Pro uses MLC nand and the 840 uses TLC nand. The TLC has more bits per cell than MLC, and therefore has a reputation of not lasting as long....whether or not that's true is up for debate. Also, the capacities are different. 128/256/512GB for the Pro models, 120/250/500 for the regular models. I think the 840 Pro has a longer warranty too.

If you really want to know the ins and outs of it, look up SLC nand, MLC nand, and TLC nand.

SLC = Single-level cells
MLC = Multi-level cells
TLC = Triple-level cells

Thanks mate I think I shall have to stick to the straight 840 as the finances are a bit stretched at the moment and I am not in any desperate rush

The 250 as the 120 is getting a bit full.
