    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

    The 256GB Samsung Pro should be the same as the 512GB its the smaller drives that have reduced write speed, less cache, etc. I've had both the Samsung and server m4 drives the Samsung is definitely faster but your only going to perceive it if your booting or running benchmarks most likely. I've also had several Sandforce based drives and wouldn't accept one any more for an OS drive unless its Intel. I got fed up with BSOD even if its as infrequent as twice a month its still annoying.

    EDIT: I do see slightly higher read latency than the 512GB drives in the reviews (.09ms/.061ms) although its still better than the m4

    So here is a quote from a Samsung 840 Pro Review:


    Not too inspiring....


    See:
    Samsung 840 Pro SSD 256 GB Review | techPowerUp



    The best feature of the Samsung 840 Pro seems to be it's outstandingly low idle power usage.

    yea I agree with u ....sf based drives used to have lot of issues like BSOD and TRIM, but these issues were resolved with their firmware updates and the fact is that because of their unique dura write and garbage collection technology, many still prefer sf controller

    Alot of interesting information here. And a truly entertaining rant between Samsung vs Intel folks. I gotta say, alot of all this is exaggerated. I had 2x Intel 520 in Raid0 and they performed awesomely, I just replaced them with 2x Samsung 840 PRO in Raid0 which guess what......performed awesomely also.

    In the end I must admit the Samsung is smoother and faster than the Intel But the fact that the 520 and 840 Pro are compared to each other despite very different launch dates proves Intel is an incredible SSD...Just slightly behind a much newer Samsung
