TLC NAND uses more power than MLC NAND, so this drive may hurt battery life in a laptop.
Samsung claims that the TLC 840 Series SSDs perform with just as low of a power threshold as the 840 Pro. Reason dictates that this is not possible due to the fact that TLC will have a higher P/E voltage requirement.
The voltages we recorded with the 500GB TLC 840 are higher than the 840 Pro across the board. Overall this high voltage is to be expected with the nature of TLC NAND, which requires more power for Program/Erase cycles, and the sheer amount of NAND on the SSD.
The random write voltage was unsurprisingly very high, and the sequential write voltage requirement is also on the high end. Even with these relatively 'fresh' readings we feel that this would not be the best SSD for mobile applications.

The voltages we recorded with the Samsung 840 are higher than the Samsung 840 Pro across the board, and also exhibit one of the highest idle voltages that we have witnessed. This is probably due to some hefty background processes to handle the TLC NAND.
The random write voltage was unsurprisingly very high, and the sequential write voltage requirement is also on the high end. With this being a relatively new SSD, with its TLC destined to begin producing more errors over the life of the drive, we would expect these power consumption figures to grow over the life of the SSD. Even with these relatively 'fresh' readings we feel that this would not be the best SSD for mobile applications. That distinction clearly belongs with the Samsung 840 Pro.

noob question: i can use this on my laptop and just replace my harddrive for this? and i'm good to go?
Yes - SSDs are 2.5" so they will work with both laptops and desktops.
In your case you just replace your current hard drive with the SSD and you can either clone your current hard drive to the SSD (by using something like Acronis for example) or you can do a clean install of the OS on the SSD if you'd rather do that.
SSDs, not SSD's.
Does anybody on this board know how to use the apostrophe properly?
Actually I do but when I sit in front of a computer for 20 hours a day doing tax returns I get fat fingers unless I am typing and thinking numbers. Sorry that I disappointed you enough to cause you to take a crap in an online deal forum.
