Lexar NS100 Spec and Price in the United Kingdom
Built around a Marvell 88NV1120 controller, the NS100 is Lexar's SATA-tier entry, rated at 550/500 MB/s sequential with TLC NAND and a 512TB write endurance figure over a 3-year warranty. Compared to the NM790's PCIe 4.0 numbers, it's a generation and an interface behind, making it a fit for older systems, budget rebuilds, or anyone replacing a failing hard drive rather than chasing NVMe speeds.
Tied 96th of 106 models in the SSD catalog on Sequential read — 4 models share this figure. Tied 99th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers measured sequential reads at the advertised SATA ceiling and consistent burst performance.
- It uses TLC NAND and is covered by a three-year warranty.
Commonly criticised
- As a DRAM-less SATA drive it is limited to roughly 550MB/s, far below NVMe alternatives.
- Measured write throughput fell noticeably short of its sequential read figure.
