120GB SATA III 3D V-NAND SSD

The Samsung 850 EVO is a 2.5-inch internal solid state drive with 120GB capacity. It uses 32 layer 3D V-NAND memory and a Samsung MGX controller with 256MB DDR3 cache. The drive connects via SATA III interface for broad compatibility with laptops and desktops.

Suits SATA upgrades not high-capacity needs

This drive suits users upgrading older SATA-based laptops or desktops where 120GB covers the operating system and core applications. Sequential reads reach 540 MBps and writes 520 MBps with random performance up to 94,000 read and 88,000 write IOPS. Users needing larger storage volumes should consider higher-capacity models.

Software toolkit enables monitoring and migration

Samsung Magician software provides drive health monitoring, firmware updates and performance benchmarking. Data migration software simplifies cloning the existing drive to the new SSD. These tools help maintain the rated 2,000,000 hour MTBF and manage power consumption from 50 mW idle to 2.4W peak.

Questions about this item

Does my laptop or desktop need a 2.5" SATA drive bay to install this SSD?

Yes, the drive uses the standard 2.5" form factor and a SATA III interface, so a compatible 2.5" bay and SATA data plus power cables are required.

Will this SATA III SSD work if I keep an older SATA II controller in my system?

The SATA III interface is backward compatible with SATA II ports, so it will function normally though sequential speeds will be limited to the older controller's maximum.

How can I verify the 540 MBps read and 520 MBps write performance after setup?

Run a benchmark tool such as CrystalDiskMark using a 1GB test file; the sequential results should approach the rated 540 MBps read and 520 MBps write figures.
