A 500 GB 2.5-inch SATA III internal SSD with V-NAND, 512 MB DDR4 cache, AES 256 encryption and sequential speeds up to 560 MB/s read and 530 MB/s write
The Samsung 870 EVO is a 500GB internal solid state drive built for consumer desktops and laptops. It uses V-NAND memory and a 512MB low-power DDR4 cache to deliver reliable everyday performance. The 2.5-inch form factor fits standard SATA drive bays. AES 256-bit hardware encryption with TCG Opal 2.0 and IEEE 1667 support protects stored data.
The drive connects through the SATA III interface, reaching up to 560 MBps sequential read and 530 MBps sequential write. These speeds saturate the SATA bus, making the interface the limiting factor for throughput. The 512MB cache helps sustain write performance during large file transfers. Compatibility testing covers major chipsets, motherboards, NAS units and video recorders.
Under continuous use the 870 EVO is rated for 2,400 TBW, reflecting its ability to handle heavy write workloads such as 8K video processing. Average active power draw is 2.2W with a 3.5W maximum, while idle consumption drops to 30 mW. MTBF of 1,500,000 hours and 1500G shock resistance support long-term reliability in demanding environments.

It means the drive can sustain read transfers at the SATA III interface ceiling, so large files and boot sequences load at the maximum pace the 6 Gbps link allows.
SATA III tops out at 6 Gbps, so the 560/530 MBps sequential figures are the practical limit; the drive reaches that ceiling and cannot exceed it.
It fits a standard 2.5-inch drive bay with a SATA data and power connector, using 7 mm z-height and the same mounting holes as a notebook hard drive.
