HP EX900 250Gb NVMe tech review

EX900 (250Gb) produced by HP works on Silicon Motion SM2263XT. The EX900 comes equipped with Micron TLC flash memory. Internal SSD is offered also in three capacities, including 1 Tb, 120 Gb and 500 Gb volume sizes.

Performance and benchmarks

NVMe SSD use PCIe M.2 3.0 x 4 bus with sequential write speeds equals to 1500 Mbps, and read speeds 2100 MB/s. It also has IOPS 120000 on reading and 108000 on writing operations.

Endurance and warranty

HP provide 3 years warranty limited by 103 TBW. As well it has 2 million hours mean time between failure.

HP EX900 250Gb use PCIe Gen3 that is significantly slower than PCIe Gen4. The write speed is 1500 Mb/s, that is slower than has most of competitors. The drive has endurance 103 TBW, that is not much compared to competitors. On balance, HP EX900 250Gb has more minuses and our site highly do not advise to spend money for it.

HP EX900 M.2 250GB PCIe NVMe Internal SSD Benchmark Test #DATA_RECOVERY_BD


The EX900 250Gb has no dynamic random-access memory (DRAM) or information about it is not known. Dynamic Random-Access Memory in their controller help to increase endurance and input/output performance.

The HP EX900 due to the low density of memory chips may run without additional heat sinks. Some motherboards from the factory has additional cooling below or above the storage for better productivity during times of heavy loads.

The EX900 250Gb has sequential write speed 1500 Mb per second, sequential read speed 2100 Mb/s. NVMe run on Silicon Motion SM2263XT controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND flash memory type is Micron TLC.
