-
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:

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
| Pros | Cons |
|---|---|
| Affordable (~USD 55–90) w/ solid read/write speeds | DRAM-less—slower small/random I/O than higher-tier SSDs |
| Durable—shock/vibe resistant, no moving parts | Slightly less consistent performance under heavy load |
| Low power consumption & quiet operation | Slightly lower TBW compared to premium SSDs |
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.

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.
