SSD endurance is typicaly expressed in drive writes per day. As SSDs don't "spin up" the MTBF means nothing to these drives. It's silly really. This drive is $16 less than an 850 Pro, so they will sell precisely zero to informed customers. Stupid pricing for what appears to otherwise be a decent product if you still need SATA. If the pricing was aggressive that 2TB would find a home in many PS4s I'm guessing.
If anything, it actually shows how clueless ADATA is. They are a 3rd tier SSD vendor, charging tier 1 prices. They don't make controllers, NAND or firmware. They have high failure rates (I can't count how many SP500's I've mailed in) at least their warranty process is fairly quick with a 3-4 day turn around. I don't know who anybody buys their products.
Doesn't matter. There is no mechanical wear from startup, like in an HDD, and this thing is not getting hot (i.e. it doesn't profit from cooling cycles).
For client usage, queue depths around 1-3, you get *NO* benefit for using a M.2 PCIe SSD over a SATA3 one. Transfer and use of very large files (talking GigaBytes here) see improvement, but that's all.
Hell, I've installed programs and games on a RAMDrive in my computer and I couldn't notice a difference between that and my 850 EVO. Maybe if I had a stopwatch going I'd detect a couple tenths of a second difference between game loads.
Games are not really optimized for the hyper speed of a ram drive or even an SSD even at loading.
But yes, unless you move really huge chunks of data (100GB+), work editting 4k HD videos there's literally 0 benefit between sata ssd and nvme pci-e top of of the line SSD.
SSDs which are choosen appropriately for their write workload don't usually wear their flash out, but rather the controller or something else breaks at some point. An MTBF of 2 Mio hours claims ADATA is confident this won't happen to their drives too soon.

2,000,000 hour MTBF? That's enterprise drive level ratings. Is that at a 24X7 duty cycle?fanofanand - Friday, December 16, 2016 - link

Sorry for the 2nd post, but without encryption nobody would put one of these in a datacenter. This is a very consumer-focused device.MrSpadge - Monday, December 19, 2016 - link

Nothing ultimate about sata3 speeds anymore.LordanSS - Friday, December 16, 2016 - link

I take it 640k is enough memory for you too?Hrel - Sunday, December 18, 2016 - link
Why do they list a MTBF? Anton do you, or anyone else over there, know why that's even listed?vladx - Sunday, December 18, 2016 - link
Because that's the only info relevant to endurance currently in their possession?MrSpadge - Monday, December 19, 2016 - link
