Samsung SSD 990 EVO Plus 2TB review

The Samsung SSD 990 EVO Plus 2TB is an M.2 2280 NVMe drive released on 25 September 2024. It uses a PCIe 4.0 x4 or PCIe 5.0 x2 interface and supports NVMe 2.0. Samsung rates sequential reads at up to 7,250 MB/s and sequential writes at up to 6,300 MB/s.

The 2TB capacity gives room for an OS, a project library or a set of container images and VM disks on one device.

Samsung specifies random read of up to 1,000K IOPS and random write of up to 1,350K IOPS at QD32 for the 2TB model. Samsung ran those tests with IOmeter 1.1.0 on a Ryzen 9 7950X system, and the figures are not guaranteed. Treat them as a ceiling under favourable conditions.

Reviewers point to two limits. The first is the DRAM-less design, which uses HMB only. That gives the drive a slight disadvantage in sustained random I/O against DRAM-equipped rivals. The second comes from one source only: write speed drops on very large sustained transfers once the SLC cache is exhausted.

Because of those reports, the drive suits bursty workloads, such as installing software, loading projects and moderate file copies, better than long, continuous bulk writes. If you regularly push very large transfers in one go, expect the rated write speed not to hold for the whole job.

Owners and reviewers describe the drive as cool and efficient. Reported peak temperatures sit in the 49°C to 73°C range under load. That is a useful result for a drive rated at this speed.

The drive ships without a heatsink. Samsung recommends placing the 990 EVO Plus under a motherboard heatsink to avoid throttling. If your board has an M.2 heatsink, that covers the advice. If it doesn't, you will need to budget for a separate one, and that is the main extra cost to plan for.

The 2TB model carries a 1,200 TBW endurance rating. The warranty runs for five years or until the rated total bytes written is reached, whichever comes first. Both limits count, so a write-heavy workload could end cover before the five years are up.

For typical desktop, development and homelab use, the TBW figure is a sensible one to check against your own write volume. Logging-heavy servers, build farms and busy databases are the cases where it deserves a closer look.

Reviewers describe Samsung Magician as a strength, providing firmware updates and drive-health information. For a sysadmin or homelabber, that means a vendor tool for keeping firmware current and checking drive condition without reaching for third-party utilities.

The drive suits someone building or upgrading a PC, workstation or lab machine who wants 2TB on a single M.2 2280 stick. It fits best where a motherboard heatsink is already in place and workloads are mixed rather than constantly writing huge files.

It is less suited to anyone who needs top sustained random I/O, since the DRAM-less design trails DRAM-equipped rivals there, or to buyers who expect a heatsink in the box.
