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.

商品問答
What does the SATA III 6 Gb/s interface mean for real-world transfer limits?
The SATA III 6 Gb/s link sets the maximum bus bandwidth; sustained throughput depends on the 7200 RPM platters and 1664 MB cache
What physical space and power does this 3.5" drive need to fit in a desktop?
It measures 3.98 in wide, 5.75 in deep, 0.79 in high, weighs 0.88 lb, and draws +5 V 0.72 A and +12 V 0.52 A
How is the drive installed and which step is often missed?
Mount the 3.5" unit in a bay, connect the standard SATA data and power cables, then enable the drive in BIOS so the OS can initialise it
