512GB 2.5" SATA SSD for consumer PCs

The Samsung 850 PRO MZ-7KE512BW is a 512GB internal solid state drive built for consumer laptops and desktops. It uses a 2.5 inch form factor and the SATA interface. The drive employs 3D V-NAND with 32 stacked cell layers and a Samsung MEX controller.

SATA III interface limits sequential speed to 550

The SATA III interface caps maximum sequential read at 550 MBps and write at 520 MBps. Random 4KB performance reaches 100,000 IOPS read and 90,000 IOPS write. These figures represent the practical ceiling of the SATA standard for this drive.

2 million hour MTBF defines endurance

A mean time between failures of 2,000,000 hours signals the endurance level of this SSD. AES 256-bit full disk encryption is included for data security. Power draw is 0.05W idle and 3.50W active across an operating range of 0°C to 70°C.

Questions about this item

Should I choose the 512 GB capacity or a different size?

The 512 GB model provides ample space for an operating system, applications and a large media library while keeping cost lower than higher-capacity versions.

What do the 550 MB/s read and 520 MB/s write speeds mean for everyday use?

They translate to fast boot times, quick application launches and smooth large-file transfers, limited by the SATA III interface ceiling.

How does the SATA III interface affect real-world performance?

The SATA III link caps throughput at around 550 MB/s, so sequential speeds cannot exceed that ceiling even though the controller and 3D V-NAND could go faster.
