Īs if it matters, they probably just put what they have on the line that day from supplier. The Sabrent Rocket you listed as expensive is using Phison E16 and is PCIE 4.0, $110 on Amazon for 1TB currently. Adata also has a few older drives based on Realtek controllers. There's a few one off such as Toshiba's TC58NCP090GSB on the XG6 and WD/Sandisk's in-house controller on WD Black SN750. Looking at the list for PCIE 3.0x 4 it seems there's only Samsung in-house, Phison, Silicon Motion, Marvell (only on Plextor's drives). Seagate Firecuda isn't listed as using a Phison E12, however this suggests these sites say it is a rebrand:. MydigitalSSD BPX Pro is listed as DDR3L or DDR4, same goes for the PNY XLR8 CS3030.

Corsair has Hynix DDR4 on their MP510 (with highest rated endurance), Team Group's MP34 similarly lists Hynix DDR4-2400, Gigabyte Aorus has DDR4 as well on the Aorus RGB SSD
