| Summary | Same hardware as the WD_BLACK SN850X, with older TLC flash than the GX 7100 and GX PRO 8100; a heatsink version fits the PS5. | Same hardware as the WD_BLACK SN850P: a GX PRO 850X sold only with a heatsink and licensed for the PS5. | Same hardware as the WD_BLACK SN7100; DRAM-less, unlike the GX PRO models, and built for low power use in laptops and handhelds. | Same hardware as the WD_BLACK SN8100; draws little power for its speed but can still run hot without a heatsink. | Same hardware as the WD Blue SN5100, with QLC flash, unlike the GX models, so writes slow sharply once the cache fills. |
