    This is tough. The Sammy Pro 256gb SSD vs. the Sammy 840 500gb.

    I've never used 500gb, but I don't know what the future holds about that. I'm not a heavy program user, or network guy, and I don't anticipate I will be. The 840 Pro is stellar, but the 840 seems adequate. What to do.

    If this is for setting up your OS X HDD,

    Get 256GB and enjoy speed. Extra storage you can always buy later, but speed you can't.

    Not going to notice a difference. Get the bigger drive.

    If you need the space, go with the larger drive. As another poster pointed out, you're not going to notice the difference in speed.

    I suppose you really haven't reason to go with the bigger one u less you need the space in which case it's a no brainer

    You're not going to notice the difference.

    I mean, they're both SATA 6.0 gb/s devices. I assure you 100% that you will not notice any material difference in speed.

    There is one other thing to consider.

    The 840 Pro is MLC NAND and the 840 is TLC NAND, which is probably why the two different sized drives are similarly priced. If you want to understand the technical difference in detail, consult the Anandtech website and read the 840 review, but the short of it is that TLC NAND is a newer technology that, while cheaper, isn't as durable because the drive writes 3 bits per transistor as opposed to 1 in SLC and 2 in MLC.

    Samsung has a good reputation for reliability, and probably wouldn't put out a drive without having worked out the durability issues, but they did use MLC in the 840 Pro for a reason.

    I decided to stick with a 128-256GB since they are reasonable, and I figure later on I can upgrade, I just hate spending money now then in a few months the SSD will be cheaper, so I spent hours going back and forth. I have a 128SSD Intel but SII, need SIII with my 2012 MBP 13.

    I use an external 1.5TB USB 3 drive for everything else.

    Yeah, I think I have to agree. lower prices later. Better reliability with the Pro too.

    Thanks to all for the input.

    I went the 840 Pro route. Using TLC makes me nervous.
