TweakTown checked out the HP EX920 SSD
A quote from the article:
The HP EX920 has been the "it" NVMe SSD for most of the summer. The series was first on display at CES in January 2018 and by early May in warehouses with attractive pricing compared to Samsung's 970 offerings. Prices have dropped across the board for all SSDs since then. Today we see if the HP EX920 is still the best NVMe value and we do it in all three capacities.HP EX920 SSD Review
HP is a brand you know, but these drives don't come from the same Hewlett-Packard your notebook comes from. A company called Biwin licenses the brand to sell SSDs under the HP name. Biwin is a large SSD manufacturer that manufactures several popular SSDs that sell under different names across the world. The HP-branded drives must meet a robust series of tests dictated by HP. Each drive goes through a certification process by the big HP Company to work with its servers, desktops, and notebooks. When you buy an HP-branded SSD, it's going to work in your HP system. The EX920 is an NVMe product, so your system has to support the protocol, but other than that little detail, it's going to work.
