Samsung 850 PRO 1TB 2.5" SATA SSD

The Samsung 850 PRO is a 2.5 inch internal solid-state drive with a 1TB capacity and a SATA III interface. It uses 3D V-NAND flash memory and a Samsung MEX controller. This refurbished unit suits desktops or laptops needing a standard SATA storage upgrade.

Sustained workload behaviour

Sequential reads reach up to 550 MBps and writes up to 520 MBps, with random 4KB performance of 100,000 IOPS read and 90,000 IOPS write. The drive is rated for 2,000,000 hours MTBF and operates between 0°C and 70°C. Active power draw is 4.50W while idle consumption is 0.05W.

Installation notes

The 7.00mm height fits most 2.5 inch drive bays and caddies using a standard SATA data and power connection. No extra drivers are required for modern operating systems. Ensure the host system provides adequate airflow within the specified temperature and humidity range.

Questions about this item

How much power does the 850 PRO draw when it runs continuously at full load?

Active power consumption is rated at 4.50 W while the drive is working and drops to 0.05 W at idle, so all-day operation stays well within typical SATA power budgets.

Does the 2.5-inch 850 PRO need any extra brackets or cables beyond a standard SATA data and power connection?

The drive uses the common 2.5-inch 7.00 mm form factor and a native SATA III interface, so it fits directly into any laptop bay or desktop tray that accepts a standard SATA data cable and a SATA power lead.

Will the SATA III 850 PRO slow down an older motherboard that only supports SATA II speeds?

The drive is fully backward compatible with SATA II ports; it will simply operate at the older interface's 3 Gb/s ceiling while still delivering its low latency and 100,000 IOPS random read advantage over mechanical disks.
