Their EVO drives suffer from read degradation slowly over long periods of time. See EVO 840, after about a year it was down to 20MiB/s of continuous read speed. An SSD they call that thing. They refused warranty and released a "Speed up flash warez tool now.exe" as help, which all it did was move the data around on the SSD in the background so as to keep up the charade that their SSDs dont suffer from manufacturing/design error.
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.
Juniper is nice, ExtremeNetworks, Pluribus etc, its not like I have to eat shit from a supplier just because they have labeled it "low end", "customer" grade and so on.
It's a perfectly fine tradeoff for a consumer drive. Just because it doesn't fit your use case doesn't make it junk.
Samsung witheld/lied about the write speed, and only mentioned TurboWriteCache in hard-to-find support forums, because they know it matters for a meaningfully large segment of the market.
Its easy to state "about 250mb/s write speed, up to 500mb/s burst write speed" in marketing materials, if it didnt impact the sales as you state for consumers, why wouldnt they?
