The Lexar NS100 1TB Internal SSD is the single most cost-effective upgrade you can make to an old laptop or desktop. Swap your spinning hard drive for this 2.5' SATA SSD and your machine will boot in seconds, load apps instantly, and handle large files without grinding — all without touching the processor, RAM or anything else.

Speed
550MB/s Read · 450MB/s Write
A typical mechanical hard drive reads at 80–120MB/s. The NS100 reads at up to 550MB/s — roughly 5× faster. In practice this means Windows boots in under 15 seconds, applications open immediately and large file transfers that used to take minutes take seconds.

Storage
1TB TLC NAND
1TB is enough for a Windows installation, a full suite of applications, a game library and a large photo or video collection — all on a single drive. The NS100 uses 3D TLC NAND flash with no cache dependency, which keeps performance consistent under sustained write loads.

Reliability
No Moving Parts · 3-Year Warranty
SSDs are fundamentally more reliable than hard drives — no spinning platters, no read heads, no mechanical failure modes. The NS100 is shock resistant (1500G) and vibration resistant, runs cooler, uses less power, and comes with a 3-year Lexar limited warranty. All Lexar drives are tested across 1,100+ devices in their Quality Labs.

Great choice if you…
✔ Have a laptop or desktop with a slow 2.5' HDD
✔ Want a fast, simple, affordable upgrade
✔ Need 1TB of storage — OS + apps + games + files
✔ Want a reliable branded drive with a 3-year warranty
✔ Use a desktop, laptop, server or workstation with SATA III

Consider something else if…
✖ You need an M.2 NVMe drive — see the Lexar NM800
✖ Your machine has no 2.5' SATA bay
✖ You need NVMe speeds (3000+ MB/s)
