Pros & Cons

Pros

✓ AES 256-bit full-disk encryption built into the drive
✓ Zero moving parts: silent, no spin-up lag, shock resistant
✓ Standard 2.5-inch SATA III fits most laptop bays and desktops
✓ Samsung makes its own NAND, controller, and firmware in-house

Cons

✗ 250GB fills fast if you install more than a few modern games
✗ SATA III caps throughput well below any NVMe M.2 drive
✗ 840 EVO is an older TLC generation, not a current Samsung line
✗ No M.2 option; needs a 2.5-inch bay or an adapter bracket

Manufacturer description

The Samsung 840 EVO 250GB (MZ-7TE250BW) is a 2.5-inch SATA III internal solid state drive built to replace an aging mechanical hard drive without replacing the whole machine. Because there are no moving parts, you get silent operation, no spin-up delay, and better resistance to the shock and vibration that kill spinning platters in a laptop bag. The 250GB capacity lands in the sweet spot for a boot drive holding Windows, your core applications, and a working set of games or project files. Samsung builds the NAND, the controller, and the firmware in-house as the number one memory…

Frequently Asked Questions

Will the Samsung 840 EVO 250GB work in my laptop?

It uses the standard 2.5-inch form factor with a SATA III interface, so it fits any laptop or desktop with a 2.5-inch SATA drive bay. Check your laptop's bay height clearance before ordering.

Is 250GB enough for a boot drive?

250GB comfortably holds Windows, your everyday applications, and a working set of games or project files. If you keep a large media or game library, plan to pair it with a secondary drive.

Does this SSD support encryption?

Yes. The 840 EVO includes AES 256-bit full-disk encryption, so data security is handled by the drive itself rather than by software running on your CPU.

How reliable is the Samsung 840 EVO?

Buyer sentiment is strong. It has no moving parts, which removes the spin-up and mechanical-failure modes of a hard drive.

What warranty does this drive come with?

Warranty terms vary by seller and region for this single-unit version. Check the current product listing and Samsung's support page for the coverage that applies to your purchase.
