HP EX920 2Tb NVMe SSD technical review

HP EX920 2Tb use Silicon Motion SM2262 controller. The NVMe write a data location map on Dynamic-Random Access Memory Nanya DDR3 to launch a programs without delays. The EX920 comes equipped with Micron TLC flash memory. SSD also available in three capacities, including 1 Tb, 512 Gb and 256 Gb volume sizes.

Performance and benchmarks

Storage use PCIe M.2 3.0 x 4 with maximum write speeds equals to 1800 MB/s, and sequential read speeds 3200 MB/s. EX920 has IOPS 260000 on writing and 350000 on reading operations per second.

Endurance and warranty

Manufacturer provide 3 years warranty period limited by endurance 528 TBW. As well it has 2 million hours mean time between failure.

EX920 (2Tb) produced by HP support PCIe 3.0 that is undoubtedly slower than PCIe 4.0. The write speed is 1800 Mb/s, that is slower than has most of competitors. The NVMe can write 528 TBW, that is bad in comparison with nearest rivals. Weighing all these factors, HP EX920 2Tb has more cons and our editor strongly do not advise to spend money for it.

HP EX920 M.2 NVME in Lian Li PC-011 Dynamic - Install & Review


The HP EX920 has Nanya DDR3. Dynamic random-access memory (DRAM) in their controller help to improve input/output performance and endurance.

The EX920 2Tb due to the high density of memory chips you need to install of additional heat sink. This would decrease temperature of the memory chips and controller. Some laptops or motherboards designed with additional cooling below and above the drive for improving performance during heavy loads.

The HP EX920 has write speed 1800 Mb per second, maximum read speed 3200 Mb per second. It operate on Silicon Motion SM2262 controller and M.2 3.0 x 4 interface standard. The NAND flash memory type is Micron TLC.
