  1. Which SSDs are we talking about? They make a lot of different models, some of which are quite old.
  2. Best answer
    1. No the 8GB's do not make any difference.
    2. Follow this order (from best to worse) for the model of the SSD 840 PRO > 840 EVO > 840 > 830
    3. If they both are from the Same model series, for example if both are 840 Pro, then go for the cheaper one.
    4. If any of them or both of them are from 830 series then just ignore it.

    Best could be that you should post both the drives model number and let us just judge it out on what to get.

    Also post the prices of both of the drives.
  3. 840 EVO < 840 PRO. The pro is the high end one, the evo replaces the vanilla 840.


    None of those have both 120 and 128GB versions.

    Thanks for letting me know that. I appreciate it. Also I have updated the same.

    Samsung 840 Pro Series 120 or 128
    i will be using it for OS a few games and programs

    Also post the prices of both of the drives.
  6. Well.. you might want to correct your post. I see nothing other than what I already posted being posted back under quotes. You might want to correct that as we don't get any information from that.
  7. The difference is actually attributable to the type of controller being used.

    For example Sandforce - 120 GB
    Marvel / Samsung = 128 GB

    120 leaves ya with 112 GB usable .... 128 w/ about 119
  8. Not really, the 840/840 Evo has a Samsung chip in it, yet has a 120GB version.

    Adata made a SF-22xx based 128GB SSD with reduced overprovisioning.
  9. Sandforce drives were 120GB because they used that extra 8GB to distribute writes, so that the flash would last longer. Marvel didnt, so it had that extra capacity.
    No reason why Samsung couldn't do that on their own controller. The 840 uses TLC flash which degrades quicker, so sacrificing that 8GB for write distribution on that drive and not the 840 Pro (uses MLC flash, which is more resistant) makes sense.
