Lexar NS100 Spec and Price in Italy

SATA1TB2.5-inch550 MB/s read

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.

How to choose an SSDFour questions decide almost every SSD purchase — what fits, how big, how fast, and how much it should cost.NVMe or SATAWhich interface your machine takes, how to tell without opening it, and what the speed difference actually buys you.How much SSD capacity you actually needHow to size a drive from what you already use, why leaving headroom matters, and when one bigger drive beats two small ones.M.2 sizes and SSD form factorsWhat 2280, 2242, and 2.5-inch mean, which one your machine takes, and how to check the keying before you buy.What SSD speed numbers actually tell youSequential versus random performance, why the number on the box describes the rarer case, and how to read it without being misled.PCIe generations for SSDsWhat Gen 3, Gen 4, and Gen 5 change, why a newer drive always works in an older slot, and when the extra speed is worth paying for.TLC, QLC, and DRAM-less SSDsWhat the NAND type and the controller's cache change about how a drive behaves, and when either is worth caring about.SSD endurance and warrantiesWhat TBW and DWPD actually promise, how much a normal machine writes, and when endurance is worth paying extra for.How to install an SSDFitting an M.2 or 2.5-inch drive, choosing between cloning and a clean install, and what to check on the first boot.When an SSD price is actually goodWhy price per terabyte beats any discount percentage, and why a good price on one capacity says nothing about the others.

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.
