Our take on the Samsung MZ-7PD256E 256GB 840 Pro Series 2.5in Internal Solid State Drive

The Samsung 840 Pro is a 2.5-inch SATA III solid state drive with 256GB of capacity and 256-bit AES encryption. It was one of the fastest SATA drives of its generation, with sequential reads around 540 MB/s and writes around 520 MB/s, and it built a reputation for steady performance and long life. It suits older laptops and desktops that still have a 2.5-inch SATA bay and need a dependable boot drive. Against newer SATA drives it holds up on everyday speed but lacks the higher endurance ratings and lower power draw of later models, and it cannot match NVMe drives at all.

Questions and answers

Is the Samsung 840 Pro still worth buying?
For an older laptop or desktop with a 2.5-inch SATA bay, yes. It is fast and reliable for everyday use. If your machine supports NVMe, a newer drive is a better fit.
How fast is the 840 Pro?
Samsung rates it at about 540 MB/s sequential read and 520 MB/s sequential write over SATA III. Real-world speeds depend on your SATA controller.
Does it work in a laptop?
Yes, it is a 7mm 2.5-inch drive that fits most laptops with a standard SATA bay. Check that your laptop takes a 2.5-inch drive rather than M.2.
What is the endurance rating?
Samsung rated the 256GB model at roughly 73 TBW, or terabytes written. That is fine for typical desktop use but lower than later SATA drives.
Does it support encryption?
Yes, it has 256-bit AES hardware encryption. You need to enable it through your system's drive encryption tools.
What comes in the box?
The drive itself, typically with documentation. Mounting screws and a SATA cable are not always included, so check your kit.
