ATTO - Transfer Size vs Performance

ATTO is a handy tool for quickly measuring performance across various transfer sizes and it's also freeware that can easily be run by the end-user.

AS-SSD Incompressible Sequential Performance

Similar to ATTO, AS-SSD is freeware as well and uses incompressible data for all of its transfers, making it a valuable tool when testing drives with built-in compression engines (e.g. SandForce).

    Wow, that validates all of the other reviews I've been reading about this drive. Great performance, great value, and no TLC NAND worries. I'm getting one for my new laptop.

    If you want a great value you better wait for a few months (maybe more than a few) till 3D NAND drives are going to come out from SanDisk, Micron, Intel, Toshiba. Then Samsing will not be the only company with 3D NAND drives and prices will probably going to come down.

    Thanks for the info! I will wait it out to get the best 3D NAND drives.

    I'm kinda surprised you didn't draw more attention to the 850 EVO as a competitor, which is neck-in-neck with pricing.

    Yes, similar value for the money, and definitely more than the 840 EVO....

    I have to admit that I totally overlooked the 850 EVO as I was kinda assuming that its price would be higher. I put this review together on a very short notice as Ryan couldn't get the MacBook review finished for today, hence my mistake of not paying enough attention to the prices (even though I updated the table today...). Anyway, I've updated the conclusion to take the 850 EVO into account because as you said, the pricing is very close and it does provide a little higher performance.

    While the 850EVO is definitely a competitor for the BX100 the fact that it uses TLC NAND vs. MLC for the BX100 is a big deal for many people who aren't as yet convinced the 850EVO won't be affected by the read issue that is still a problem with the 840EVO. I realize the cell size for the 850 EVO's 3D NAND is much greater but as I wrote above many people, myself included, don't see the need to roll the dice on the 850EVO when the BX100 will provide basically similar performance.

    The 850Evo is $20-$50 more on all models here in Canada. Not sure what stateside or Euro Pricing is like.

    I just bought a 1TB EVO for $350 on Amazon, USA

    Kristian, hopefully you'll be helping Ryan with that MacBook review by covering the NVMe(!) SSD it ships with in depth. Looks to be a PCIe 2.0 x4 connected device dubbed "AP0256H", so possibly a semi-custom Apple controller based on the Marvell 88SS1093.
