Samsung 870 EVO 500 GB SATA SSD

The Samsung 870 EVO MZ-77E500E is a 2.5-inch internal solid-state drive with a 500 GB capacity. It connects through the SATA interface and uses V-NAND MLC memory with a 512 MB DRAM cache. The drive is built for desktop PCs, notebooks and storage-system devices.

7 mm height fits standard 2.5-inch bays

Installation is straightforward: mount the drive in a 2.5-inch bay, connect the SATA data and power cables, then restart the system. Samsung Magician software is available for drive management and firmware updates. The 7 mm z-height matches most laptop and desktop cages.

Check SATA port and 2.5-inch mounting space

Before ordering, confirm the host has a free SATA III port and a 2.5-inch drive bay or caddy with 7 mm clearance. Verify the system BIOS or UEFI recognises SATA storage devices. Ensure a SATA data cable and power connector are available for the new drive.
