870 EVO Series 2TB SATA SSD

The Samsung 870 EVO Series provides 2.0 TB of storage in a 2.5 inch form factor. It connects through a SATA III interface and uses V-NAND MLC technology. This internal solid state drive is built for consumer workloads.

SATA III practical limits

The SATA III interface caps sequential throughput at 6 Gbps. Real-world speeds reach up to 560 MBps for reads and up to 530 MBps for writes. The drive fits standard 2.5 inch bays with a 7 mm height profile.

Sequential read speed decides fit

A maximum sequential read of 560 MBps shows whether this drive matches the performance envelope of a SATA-based laptop or desktop upgrade. If the system requires faster throughput, a different interface is needed.

Questions about this item

Which capacity of the 870 EVO Series should I choose for a large media library?

The 2.0 TB model provides the highest capacity in this series, giving ample space for extensive media libraries, games, and applications.

What do the 560 MBps read and 530 MBps write speeds mean for daily use?

These sequential speeds represent the maximum throughput over the SATA interface; real-world file transfers and application loading will typically be somewhat lower but still fast for general workloads.

How does the SATA III interface limit the drive's performance?

SATA III caps the theoretical bandwidth at 6 Gbps, so the drive cannot exceed its rated 560 MBps read and 530 MBps write regardless of the NAND technology inside.
