    actually I got to chime in. I was scrounging all over the internet for decent 256gb Samsung Pro reviews and I couldn't find much meaningful data. I believe the huge advantage in performance you see out there is because of the 512gb drive that everybody reviews. It is already well known that increasing capacity improves sequential write performance of SSDs, often at the cost of 4k random performance (at least this was true with Sandforce drives). For me, by far the most important metric is 4k Random read performance, this will determine my bootimes and UI snappiness. The weird thing is, the Samsung Pro was posting insane figures like 38mb/s random read performance but I noticed this was only on the 512gb model, I noticed the advantage isn't so pronounced on the 256gb model.

    That greatly depends on what SSD you are looking at.
    For Samsung 840 PRO the 256GB and the 512GB are equally fast both with sequential transfer and with 4K (both read and write). The 64GB is slower. So no, the results you see in the review I posted is just as valid for the 256GB.

    The 840 PRO could actually be faster than what you see in the review (real world results) I posted since the reviewer didn`t use the latest firmware. I doubt it would impact real world though but who knows.

    I would personally go for the Samsung 840 Pro series. I own one and it works amazing :)

    I'm just going to chime in and say with these 3 brands, once you purchase the 240/256GB -480/512GB versions it makes NO difference, not for real world tests. You won't feel the slightest (unless you know what you are doing)

    Just buy whatever you think fits you and what is priced the best for you, SSD's now a days are reliable and good, so the only thing to pick is the brand and version lol

    jaug1337,

    I don't think that is a fair assessment judging by the link I gave in post #3 in this thread.

    I will be fair, you are correct, but this is purely my own honest opinion, having several friends with these SSD's and having a Crucial M4 myself, I can feel a SLIGHT difference, but not really

    I don't just want to be right - could you give more details on the specific SSD's and the relevant platforms/workflows they're used in?

    Gaming, browsing.

    I have no idea what the OP wants to use them for, either way I didn't feel any difference.

    A Plextor M5P, Samsung 840 Pro, Intel 520, Crucial M4, HyperX and a OCZ Agility 4

    irrespective of the controller; OCZ has been known for quality issues. currently I am using Intel 520( sandforce based ssd) I haven't seen single issue and everyone telling that sandforce based ssd's not good with already compressed data, even that issue also i haven't noticed till now. sandforce fixed all bugs long ago with their firmware updates
