A quote from the article:
HP EX920 M.2 NVMe SSD Review (1TB)
High performance, low power, increased system responsiveness, high reliability, small form factor, minimum weight, enhanced ruggedness along with high data integrity and security; these are the selling points made by HP with respect to their newest HP EX920 M.2 PCIe 3.0 x4 NVMe SSD. As much as this description might fit any of the latest gen M.2 SSD family, HP has built a product that we believe is going to do very well in the SSD industry, a product that very well might raise more than a few eyebrows.
The HP SSD EX920 M.2 SSD is a PCIe Gen 3 x 4 2280 (80mm) form factor NVMe SSD compatible with the latest NVMe 1.3 protocol. It will be available in 256GB, 512GB and 1TB capacity points, and throughput is rated at 3200MB/s read and 1800MB/s write, the write performance dropping back to 1600MB/s for the 512GB and 1200MB/s for the 256GB storage point. IOPS is rated at 350K/250K read and write for the 1TB model which again is a bit lower for the lesser capacities.
