I don't think you could buy fastest 2TB SSD for $280. More like $20'000 for 6TB.

Fastest SSDs are not Samsungs, ADatas, SunDisks or other "household" brands (yes, I know, that Samsung has enterprise models, without names, only with partnumbers, but even these models are not "fastest").

It is special brands, prices for which is not publicly available (or my google-fu is not strong enough).

Everything you buy for $280 will degrade when 75% full, and even sustained linear write will tank after first several tens of gigabytes, when SLC caches will be full. Not to mention random write with small blocks.

Special enterprise SSDs, like DataEngine T2HP, costs much, much more (and don't have 2TB models, looks like it starts from 4TB or even 6TB now, but still it is not like x2 or x3 to $280, it is more like x50).
