This review covers the new HP EX900 series, this more affordable series EX900 500GB model is plenty fast with a rated sequential read speed up to 2100 MB/s and sequential write speed up to 1500MB/s. In our testing, often this SSD surpassed these speeds.

The specs are great, but will this unit deliver what it claims? M2 is the interesting form factor, these small storage units are evolving from being "just as fast" as a regular SSD towards double, triple, quadruple, quintuple, sextuple, septuple and perhaps in the future even octuple that performance. It comes in a different package, M.2. Using the PCIe lanes interface it is so much more capable as it can deal with way more bandwidth using PCI-Express lanes. As such, M.2 solutions are intended for high-end and enthusiast class motherboards and laptops. The EX920 series M.2 SSDs are a stunningly fast series of storage technology as they offer enthusiast class performance as you are looking at a product that reads well over 3GB/sec and writes close towards 2 GB/sec. These new M.2 units use the NVMe protocol and that means storage technology at millennium falcon hyper-fast speeds while remaining competitive in pricing.
