    After the SLC cache saturated, the SN770 wrote at roughly 560 MBps for the remainder of the test. So, the nice benchmark tests are mostly testing the SLC cache.

    The tests which show the weakness of DRAMless SSDs were not tested. Though most of those are probably not common end user usages.

    If you are willing to spend a bit more, then for your "primary" PCIe gen 4 x4 SSD, is this really a great choice? The SSD controller is well tunes, but the actual NAND flash may not be that great.
