Description 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 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. Specs Summary Feature 1 TB Lexar NS100 Interface 2.5″ SATA III (6 Gb/s) Read Speed Up to 550 MB/s Write Speed ~500 MB/s (sustained ~450 MB/s) NAND 3D TLC, DRAM-less Endurance (TBW) 480 TB Warranty 3 years Shock/Vibration Rating 1500 G / 10–2000 Hz Operating Temp 0–70 °C 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.
