Lexar NS100 2.5” SATA III SSD (6Gb/s) 1TB

Overview & Features

• Form Factor & Interface: 2.5″, 7 mm thick SATA III (6 Gb/s) drive—compatible with laptops and desktops

• Storage Capacity: 1 TB usable space (~930 GiB formatted)

• Performance:

  • Sequential read speeds up to 550 MB/s, matching SATA III limits

  • Write speeds typically around 500 MB/s, with benchmark showing ~450 MB/s sustained write for 2 TB variant (likely similar for 1 TB)

Durability & Reliability Specs

• NAND Type: 3D TLC NAND, DRAM-less setup powered by Marvell 88NV1120 controller

• Shock / Vibration Resistance:

  • Shock: 1500 G, 0.5 ms

  • Vibration: 10–2000 Hz, 1.5 mm / 20 G

• Operating Temperatures: 0–70 °C; Storage: –40 to 85 °C

• Endurance (TBW): Rated for 480 TBW on the 1 TB model (~0.46 drive writes per day over 3 years)

Real-World Performance

• Testing on the 2 TB version showed:

  • AS-SSD total score ~710

  • Read ~497 MB/s, write ~436 MB/s

  • 4K random I/O: ~25 MB/s read, ~85 MB/s write

• Entry-level performance: good boost over HDDs but slower than SSDs with DRAM; storage review notes “not fantastic but not bad for a SATA aimed at entry-level”

Pros and Cons

Is It a Good Choice?

• Great for: Upgrading old HDD-based laptops or desktops—even older SATA II–only systems will benefit from ~3–4× speed gain.

• Not for: Heavy workloads (e.g., video editing, large database operations) or demanding random I/O use—better to choose SSDs with DRAM like Samsung or Crucial.

Specs Summary

Recommendation

If you’re seeking a quick and cost-effective SSD upgrade from an HDD, the Lexar NS100 1 TB offers excellent value—fast reads, respectable writes, and solid durability. However, if your needs include high-performance random I/O, sustained workloads, or you want extra longevity, a DRAM-equipped SSD from Samsung, Crucial, or Western Digital would be a smarter investment.
