Manufacturer description

Upgrade an aging laptop or desktop without replacing it: the Lexar NS100 256GB drops into any standard 2.5-inch drive bay and connects over SATA III, delivering sequential read speeds of up to 520MB/s. That is the difference between waiting on a mechanical hard drive and having Windows, your browser, and your working files ready when you sit down. Because the NS100 has no moving parts, it is shock and vibration resistant, which matters more in a laptop that travels than in a desktop that never leaves the desk. It also runs cooler and quieter than the spinning drive it replaces. Lexar rates…

SpecPicks Verdict

SpecPicks scored Lexar 256B NS100 Internal SSD 2.5" SATA III using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Lexar's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Will this SSD fit my laptop?

It uses the standard 2.5-inch SATA III form factor found in most laptops and desktops built with mechanical hard drives. Confirm your laptop has a 2.5-inch drive bay, since many thin models only accept M.2 drives.

How fast is the Lexar NS100 256GB?

Lexar rates it at sequential read speeds of up to 520MB/s over the SATA III interface. Write speed is not listed in the product specs, so check the manufacturer listing for that figure.

Is 256GB enough storage?

It comfortably holds Windows, office applications, and a browser plus everyday documents. If you store large game libraries or video projects, look at a higher capacity in the NS100 line.

How long will this drive last?

The 256GB model carries a 120TBW endurance rating, meaning 120 terabytes can be written over its life. Typical boot and office use writes a small fraction of that per year.

Is it actually reliable?

It has no moving parts and is shock and vibration resistant, unlike a mechanical hard drive.
