They marketed it as warranty so and so, speed such and such, and in fact its a piece of shit, and Samsung does not stand by its own product.
Even their newest Samsung EVO 850 is marketed as write speed ~500mb/s, but that is only true for the first 3gb, due to their usage of "TurboWriteCache", which means it has some kind of DRAM or faster real flash disk, and the rest of the disk is below 100mb/s in write speed.
Perhaps, they should not offer warranty on their "low-end consumer" drives, or lie in marketing/product specifications?
So that we as low-end consumers can make informed decisions? I bought SanDisk Extreme Pro instead, they are very fine disks, and did not cost much more than the evo. Recommend SanDisk strongly.
