The Guru of 3D reviewed the HP EX920 1 TB M.2. SSD
A quote from the article:
HP has released the ultra-fast new M.2. EX920 SSD series, the rather properly volume sized 1024 GB (1 TB) model which we will review is seriously fast and furious with a rated sequential read speed of up to 3200MB/s, write performance does not disappoint either, at up to 1800MB/s. Yes, HP is entering the high-end and enthusiast class with their new SSDs. The specs are fantastic, but will HP be able to deliver a unit that manages to impress? 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.HP EX920 1 TB M.2. SSD Review
