こんな風に 「HP S700 と S700 Pro SSD は Micron 3D TLC NAND を
使っているにも関わらず、HP が差別化を図るために努力をした結果、
初期のドライブのころから、同じ基本形態を持つ他のベンダよりも
チューニングを施されて明らかに高いQA(品質保証) を持っている。」
とはっきり書かれている。どういうことなんだろう？？？

HP is not a well-known name in the retail SSD market, but as a major PC OEM
it's not too surprising to see them producing their own SSD models based on
third-party controller solutions. The HP S700 and S700 Pro SSDs use Micron
3D TLC NAND and Silicon Motion controllers, but have undergone tuning and
significant QA from HP in an effort to give them an edge over earlier drives
from other vendors that are using the same basic formula.

The S700 and S700 Pro both compete in the low-end SATA SSD market segment.
The S700 Pro's closest relatives in the market are drives like the ADATA Ultimate
SU800 that use the same 3D TLC and Silicon Motion's SM2258 controller.
The S700 instead uses the Silicon Motion SM2258XT DRAMless controller,
and is the first retail DRAMless SSD we've tested in quite a while. Earlier this year
we previewed Maxiotek's MK8115 DRAMless SSD controller with both 3D MLC and 3D TLC,
and the latter configuration has since come to market as ADATA's Ultimate SU700.
