Our take on the Samsung 840 Pro 2.5 256GB SATA III Solid State Drive

The Samsung 840 Pro is a 2.5-inch SATA III solid state drive with 256GB of capacity and rated sequential reads up to 540 MB/s. It was one of the fastest SATA drives of its generation, using MLC NAND and Samsung's own controller, and it earned a reputation for consistent speed and long service life. It suits older laptops and desktops that need a fast, reliable boot drive on a SATA port. Against newer SATA drives it holds up on everyday responsiveness but trails on capacity per dollar and lacks the endurance ratings and warranty length of current models.

Questions and answers

Is the 840 Pro still worth buying?
Only if you need a proven SATA boot drive and find it at a low price. Newer SATA SSDs give more capacity and a longer warranty for similar money.
How fast is it compared with NVMe drives?
Its 540 MB/s sequential read is near the SATA limit. NVMe drives reach several times that, so it suits SATA-only machines rather than new builds.
Will it fit my laptop?
It is a standard 2.5-inch drive 7mm thick, so it fits most laptops with a 2.5-inch bay. Check that your machine takes SATA rather than M.2.
What is in the box?
The drive itself, typically with documentation. Cables, screws and cloning software are usually not included, so check before buying.
Does it work in a desktop?
Yes, any desktop with a free SATA port and 2.5-inch mount works. A 3.5-inch adapter may be needed for some cases.
Where is the Samsung 840 Pro 2.5 256GB SATA III Solid State Drive cheapest?
At Newegg, for $179.99, as of our latest check.
