TurboWrite does a good job of blurring the lines between MLC and TLC performance, while Samsung's RAPID DRAM cache offers adventurous users a way of getting a taste of high-end PCIe SSD performance out of an affordable TLC SATA drive.

The performance story is really good (particularly with the larger capacities), performance consistency out of the box is ok (and gets better if you can leave more free space on the drive) and you've got Samsung's firmware expertise supporting you along the way as well.

Crucial's 960GB M500 may just have the edge in terms of pricing, offering 'terabyte-class' drives for less than this hefty EVO SSD, but when it comes to performance Samsung has got it in spades.

The PCIe interface offers dramatically higher sequential performance, but does nothing for the random speeds - and this is arguably what really matters in terms of real-world SSD usage.

The 120GB and 250GB drives on the other hand have only 3GB, which will get filled up a lot quicker.

The reason that placing still works though is because the EVO is using a new write acceleration algorithm, called TurboWrite, to achieve some of its beefier performance scores.

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've been hearing how replacing the old mechanical hard drive with an SSD would increase performance of any PC. I wasn't sure how much of an improvement it'd be since I wouldn't be updating the processor. After I put in the SSD it was a whole new world. The laptop booted up in seconds instead of minutes. Applications opened faster and everything was more responsive. Until now I never realized how much the mechanical hard drive bottlenecked the laptop's performance (as opposed to the processor). I don't think adding more RAM can increase performance this much. I bought the 250GB for just $130 from here http://amzn.to/1ric5NU and still have plenty of room to install more softwares.The difference between the mechanical drive and SSD is day and night!
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......
