Seagate Barracuda 500GB 7200RPM 3.5" SATA ST3500418AS internal hard drive

500 GB desktop SATA hard drive

The Seagate Barracuda ST3500418AS is a 3.5-inch internal hard drive built for desktop PCs and workstations. It connects through a standard SATA III 6 Gb/s interface and spins at 7200 RPM. The 500 GB capacity suits operating-system installs, application storage, backups and media libraries. SMART monitoring helps track drive health over time.

Who this suits and who it does not

This drive fits builders adding bulk storage to a desktop tower or replacing an older mechanical disk. It works in any system with a free 3.5-inch bay and a SATA data plus power connection. Users who need the faster access times of solid-state storage or who require a 2.5-inch form factor for a laptop or compact enclosure should look elsewhere.

SATA III 6 Gb/s interface

The single specification that decides compatibility is the SATA III 6 Gb/s interface with backward compatibility to SATA II and I. Verify that the motherboard or controller provides a matching SATA port and that the power supply delivers the required +5 V 0.72 A and +12 V 0.52 A rails. The 3.5-inch dimensions of 3.98 in × 5.75 in × 0.79 in must fit the available drive bay.
