HP EX900 Pro 1 TB NVMe SSD Benchmarked
Unlike the higher-end HP EX950, the EX900 is a budget-friendly NVMe SSD with transfer rates in the ~2000 MB/s range instead of the usual ~3000 MB/s we see on pricier models. The HP drive can be found on Newegg and Amazon in 120 GB, 256 GB, 512 GB, and 1 TB capacities for $35 to $150, respectively
(November 17, 2020 update: The HP EX900 Pro is now down to $109.99 USD on Amazon to make it a much better deal than it was when it initially launched.)

Test System
Our test system is the 17.3-inch Eluktronics RP-17 gaming laptop equipped with two PCIe x4 M.2 slots and even a 2.5-inch SATA III bay. The system is easy to service which makes it a perfect host system for testing drives.
More information on the laptop can be found on our full review of the unit here.
AS SSD & CrystalDiskMark
CDM and DiskSpd confirm the ~2000 MB/s maximum transfer rates. Speeds are slower than the pricier Samsung PM981 and the recently released SK Hynix Gold P31 as expected.

ATTO
ATTO shows the EX900 not reaching its maximum transfer rate potential until block sizes are at least 64 KB or larger similar to many other NVMe SSDs. Performance when handling very small blocks of under 4 KB is faster than what we recorded on both the WD SN550 and SK Hynix Gold P31.

Verdict
The HP EX900 is launching at almost the same time as the SK Hynix Gold P31 which is able to offer much faster speeds at around the same price. It does, however, excel at handling very small blocks which may appeal to users who frequently work with large datasets comprised of extremely small files. Even so, the EX900 is a hard recommendation over the aforementioned SK Hynix Unless if prices can drop further.
The popular WD SN550 remains the cheaper drive of the three but with even slower performance when dealing with smaller files.
