    I've been reading up on the Samsung 840 250gb and the Samsung 840 Pro 512gb.

    At newegg.ca the Samsung 840 512gb is $600, but lets say that you can find it on sale for $550
    And the Samsung 840 250gb is $150 on sale right now at one of my local computer stores.

    As you can see, the Samsung 840 Pro writes considerably faster sequentially and randomly.

    But from my perspective, isn't it just better to get 2 Samsung 840 250gb, and stick them in RAID 0? It's way cheaper, and I'm assuming that you can theoretically read and write 2 times faster (I know it won't be that much). But thinking about it, the samsung 840 is a TLC (Triple Level cell) and not a MLC (Multi Level Cell) or a SLC (Single Level Cell) CLICK HERE FOR SOURCE. So since it writes 3 bits per cell, I wonder how that will impact RAID 1 performance, and also that makes figuring out the stripe size kind of tricky.

    What does everyone here think about this?

    While raid 0 is fun and looks awesome by the numbers (I know, I have run dual ssd's in raid 0
    ) you will just not see anything really compared to a single ssd unless you are transferring huge files all day long. I ended up going back to a single large capacity SSD. Also a single drive is more reliable technically and less of a pain to setup. :toast:
     
    BloodTotal says thanks.
