UMEMORY SSD-S2 Ultra 2TB internal SSD

The UMEMORY SSD-S2 Ultra is a 2 TB M.2 2280 solid-state drive built with 3D TLC memory and a Maxio controller. It connects through an NVMe 2.0 interface and is designed for desktops and laptops that need fast internal storage.

Integrated graphene heatsink

A dual-layer thermal solution combines a graphene heat spreader with firmware-based temperature management. This keeps the drive within its 0 °C to 70 °C operating range during sustained workloads without requiring extra case airflow.

Suits PS5 expansion, laptop upgrades

The 1200 TBW endurance rating and 1.5 million hour MTBF support heavy write cycles such as game installs, video editing caches and database logs. Systems limited to SATA or PCIe 3.0 slots will not reach the advertised 6400 MB/s read and 5700 MB/s write speeds.

Questions about this item

Does the M.2 2280 form factor fit my laptop?

The drive uses the M.2 2280 form factor. Check that your laptop has an M.2 slot that accepts 80 mm modules before buying.

Will the drive work with a PCIe 4.0 motherboard?

It supports PCIe 4.0 and NVMe 2.0, so it will run at full speed on a PCIe 4.0 slot and is backward compatible with PCIe 3.0.

What sustained write performance can I expect?

Sequential write reaches 5700 MB/s, and the 2 TB model is rated for 1200 TBW endurance.
