HP EX900 250GB NVMe SSD

The HP EX900 is a 250GB internal solid state drive built on an M.2 2280 form factor with a PCI-Express 3.0 x4 interface. It uses 3D TLC NAND and an HP controller to deliver sequential reads up to 2100 MBps and writes up to 1300 MBps for consumer workloads.

Sustained load behaviour

Random read performance reaches 120,000 IOPS while random writes hit 105,000 IOPS, with read latency of 0.028 ms and write latency of 0.035 ms. Active power draw is 2.99W and idle consumption is 0.68W, supporting consistent throughput during extended sessions.

Upgrade perspective

The drive upgrades systems limited by older storage interfaces when the motherboard provides an M.2 slot wired for PCIe 3.0 x4. A 100 TBW endurance rating and 2,000,000 hour MTBF indicate the jump is worthwhile for users needing higher sequential bandwidth and lower latency.

Questions about this item

Will this 250 GB drive fit my laptop's M.2 slot?

The drive uses the M.2 2280 form factor, which is 22 mm wide and 80 mm long. Most modern ultrabooks and desktops accept this size, but verify your motherboard or chassis clearance before buying.

Does the drive require a separate heatsink?

Active power draw is 2.99 W and idle draw is 0.68 W, which is low for a PCIe 3.0 x4 NVMe SSD. Many motherboards include integrated thermal pads; if yours does not, a thin aftermarket pad is inexpensive and easy to add.

How much real-world data can I write before wear becomes a concern?

The endurance rating is 100 TBW (terabytes written). At 50 GB of writes per day, that equals roughly five years of service life.
