2.5" SATA III 512GB SSD

The Lexar NS100 is a 2.5-inch internal solid-state drive with 512GB capacity and a SATA III interface. It targets everyday consumers who want faster startups, quicker application loads and snappier data transfers than a mechanical hard drive can deliver. Sequential reads reach up to 550 MB/s, and the drive is rated for 240 TBW.

Ideal for SATA laptop and desktop upgrades

This drive suits owners of laptops or desktops that have a 2.5" SATA bay and need a simple drop-in replacement for a spinning disk. It is not suitable for systems that only accept M.2 or PCIe storage, nor for workloads that demand sustained write performance beyond the SATA III bus.

SATA III interface decides compatibility

The single specification that determines fit is the SATA III (6 Gb/s) interface combined with the 2.5" 7 mm form factor. If the host machine provides a standard 2.5" SATA connector and mounting space, the NS100 will install without adapters; otherwise a different drive type is required.

Questions about this item

Will the 2.5 inch 7mm height fit my laptop drive bay?

The drive measures 7mm tall, 69.85mm wide and 100.20mm deep, matching the standard 2.5 inch SATA form factor used in most laptops and desktops.

Can I keep my existing SATA cables when installing this 512GB SSD?

Yes, the SATA III interface uses the same data and power connectors as earlier SATA drives, so your current cables will plug in directly.

How do I confirm the drive is delivering the rated 550 MB/s read speed after setup?

Run a sequential read benchmark such as CrystalDiskMark; a result near 550 MB/s shows the SSD is operating at its specified performance level.
