HP EX900 NVMe SSD 1TB SSD

Details

The EX900 is powered by the what masquerades as HP’s 8068 controller, but under the hood is a Silicon Motion SM2263XT. The SM2263XT was notable as one of the first NVMe controllers to support HMB or Host Memory Buffer in an effort to improve the performance of DRAM-less drives like the EX900. Paired with HP’s spin on the SM2263XT we have Micron 64-layer TLC NAND. Unlike with the EX900 Plus, where the NAND was a bit ambiguous between TLC and QLC I can confirm the EX900 is running TLC.
