Samsung 850 PRO 256 GB SATA III SSD
This refurbished Samsung 850 PRO is a 2.5 inch internal solid state drive with 256 GB capacity. It connects through a SATA III interface and uses 3-D Vertical NAND memory with a Samsung MEX controller. Sequential reads reach up to 550 MBps and writes up to 520 MBps. Random performance hits 100000 IOPS read and 90000 IOPS write.
Suits 2.5 inch SATA bays in laptops and desktops
The 7 mm height fits standard drive bays in notebooks and desktop PCs that accept a 2.5 inch SATA device. It draws 0.5 W idle and 3.5 W active, so it works within typical laptop power budgets. Buyers needing an M.2 form factor or a PCIe interface should choose a different model.
MTBF rated at 2000000 hours
The manufacturer specifies a mean time between failures of 2000000 hours, indicating high endurance for a consumer drive. This figure helps assess whether the SSD meets reliability requirements for long-term workloads. Operating temperature range is 0 °C to 70 °C and humidity tolerance is 0 % to 95 %.

Questions about this item
How can I confirm the drive is performing at its rated 550 MBps sequential read after installation?
Run a benchmark tool such as CrystalDiskMark and verify the sequential read result is near 550 MBps and sequential write near 520 MBps; also check SMART data shows the drive detected as a SATA III device with 256GB capacity.
What comes in the box and what must I supply myself?
The package contains the 2.5 inch 256GB SSD only; you will need to provide a SATA data cable, a SATA power connection from your power supply, and a 2.5 inch drive bay or adapter bracket for mounting.
Which capacity in the 850 PRO series should I choose for a boot drive with room for key applications?
The 256GB model offers 256GB of 3D V-NAND storage with up to 100,000 random read IOPS and 90,000 random write IOPS, making it well suited for an OS plus core programs; larger capacities in the same series provide more space but share the same performance profile.
