Manufacturer description

The Seagate Barracuda 7200 1TB is a 3.5-inch internal hard drive for desktop towers and retro PC builds where a reliable spinning drive fits better than flash storage. It spins at 7,200 RPM and pairs that with a 32MB cache, so it loads large game installs, disk images, and emulation libraries faster than 5,400 RPM drives. The drive uses a SATA 3Gb/s interface with Native Command Queuing (NCQ), which lets the drive reorder queued read and write requests to cut down on head movement during multitasking. SATA 3Gb/s matches the ports on many Windows XP and Windows 7-era motherboards, so it suits…

Frequently Asked Questions

How fast does the Seagate Barracuda 7200 1TB spin?

It spins at 7,200 RPM and has a 32MB cache. That makes it quicker than 5,400 RPM desktop and laptop drives, though still much slower than an SSD.

Will this drive work in a SATA 6Gb/s motherboard port?

Yes. The drive uses SATA 3Gb/s with NCQ, and SATA ports are backward compatible, so it runs in SATA 6Gb/s ports at its native 3Gb/s interface speed.

Can I use it in an older retro PC with only IDE connectors?

Not directly. It's a SATA drive, so an IDE-only board needs a PCI SATA controller card or a SATA-to-IDE adapter. Check that your adapter supports 1TB capacity.

Will it fit in a laptop?

No. This is a 3.5-inch desktop drive, so it needs a 3.5-inch bay in a tower case or an external 3.5-inch enclosure with its own power supply.

What warranty comes with the Seagate Barracuda 7200 1TB?

The listing doesn't state warranty terms. Check the product listing or Seagate's warranty lookup with the drive's serial number for current coverage.
