| Summary | DRAM-less: it borrows system memory (HMB) instead, which the PS5 doesn't support, so console speeds may fall short. | WD_BLACK's flagship PCIe 4.0 drive, with a DRAM cache that the SN770 and SN7100 lack. | Same drive as the SN850X, sold only with a heatsink and licensed for the PS5. | DRAM-less successor to the SN770, with newer TLC flash and better power efficiency. | Has a DRAM cache and draws little power for its speed, but can still run hot without a heatsink. |
