500 GB SATA III upgrade for everyday PCs

The Samsung 850 EVO 500 GB is a 2.5 inch internal SSD built with 32 layer 3D V-NAND and a Samsung MGX controller. It targets consumers who want faster boot times and application loading on laptops or desktops that still use the SATA interface. Sequential read reaches up to 540 MBps and write up to 520 MBps.

Fits any 2.5 inch bay with a SATA III port

The drive slides into a standard 2.5 inch slot and connects through the existing SATA III cable and power connector. No extra adapter or mounting bracket is required beyond what the chassis already provides. Low idle power of 50 mW and an average active draw of 3.0 W leave more headroom for other components in compact builds.

512 MB DDR3 cache and Samsung Magician software

A 512 MB Low Power DDR3 SDRAM cache helps sustain random read performance up to 98,000 IOPS and random write up to 90,000 IOPS at queue depth 32. The bundled Samsung Magician utility enables firmware updates, drive health monitoring and performance benchmarking so the SSD stays optimised over its 2,000,000 hour MTBF rating.

Questions about this item

When does the 512MB DDR3 cache stop absorbing writes during a long transfer?

The 512MB Low Power DDR3 SDRAM cache handles burst traffic; once it fills, sustained writes fall back to the 3D V-NAND at up to 520 MBps sequential.

How much power and heat does the drive produce when it runs all day?

Active power averages 3.0 W with a 3.5 W burst ceiling; idle power is 50 mW, and the operating range is 0 °C to 70 °C.

What connector and bay must my laptop or desktop already have for this 2.5" SATA SSD?

A standard 2.5-inch SATA III drive bay and a SATA data plus power cable are required.
