Lexar NS100 256GB SATA SSD

The Lexar NS100 is a 2.5 inch internal solid-state drive with a 256GB capacity and a SATA III interface. It delivers sequential read speeds up to 520 MBps and sequential write speeds of 520.0 MBps. The drive weighs 34 grams and measures 69.85 in by 100.2 in by 7.0 in.

Suits SATA upgrades and capacity limits

This drive suits desktops or laptops with a 2.5 inch SATA bay that need a 256GB boot or storage drive. It is not suited for systems that only accept M.2 or PCIe modules, nor for users who need capacities larger than 256GB. The 256 unknown_modifier cache and 3600 watts active power consumption are noted from the supplied data.

SATA III interface decides fit

The single specification that decides compatibility is the SATA III interface. The host must provide a standard 2.5 inch SATA connector and support the SATA III protocol. If the system uses a different interface, this drive will not install or function.

Questions about this item

Do I need a spare 2.5" drive bay and a SATA data cable to install the Lexar NS100 256GB SSD?

Yes, the drive uses the 2.5" form factor and a SATA III interface, so a compatible bay and a standard SATA data cable are required for installation.

Will the Lexar NS100 256GB SSD work in a system that only has SATA II ports?

The drive connects via SATA III and will function when plugged into a SATA II port, operating at the speed the host controller allows.

How can I verify the Lexar NS100 256GB SSD is delivering its rated 520 MB/s sequential read speed after setup?

Run a benchmark tool such as CrystalDiskMark or AS SSD and check that the sequential read result approaches 520 MB/s on a SATA III connection.
