Fast, cache-equipped Gen3 NVMe for gaming PCs and workstations.

The HP EX950 1TB is an M.2 2280 PCIe 3.1 x4 NVMe SSD with 3D TLC NAND and a 1GB cache. Reading at up to 3,500MB/s and writing at up to 2,900MB/s with 410K random read IOPS, it is a fast, reliable boot and game drive for desktops and laptops.

Why a Cache-Equipped NVMe Drive Feels Faster

DRAM-less budget SSDs can feel quick in short tests but slow down during heavy multitasking or large transfers because they lack fast memory for mapping data.

The EX950 includes a 1GB cache and TLC NAND, so random performance and sustained writes stay strong. Boots, game loads and app launches remain quick even under load.

With up to 3,500MB/s reads and 410K random read IOPS, the EX950 delivers fast boots, quick game loading and smooth everyday performance.

Dependable Reliability

An MTBF of up to 2 million hours and TLC NAND make the EX950 a durable choice for daily gaming and work.
