| Summary | DRAM-less with TLC flash; writes can slow noticeably once its small cache fills. | Uses the same TLC flash as the SN570 at every capacity, unlike the later SN5000 4TB and SN5100, which use QLC. | TLC flash at 500GB to 2TB, but the 4TB uses QLC. | Switches to QLC flash at every capacity; it slows more than the TLC models during very long writes. |
