The device also features a 176-layer TLC flash memory from SK Hynix and an LDDDR4-4266 of H54G36AYRB cache chip by SK Hynix.

After removing the front sticker, the controller, cache, and flash memory are all from SK Hynix.

Solidigm Storage Tool Monitor SSD status, health, update firmware

Solidigm’s “Storage Tool” software estimates an SSD’s remaining life, temperature, and disk usage. In addition to firmware updates and diagnostic scans, it includes tools for performance improvement and host management cache maintenance. Finally, reading SMART data correctly is possible with Solidigm’s own tools.
