Seagate Barracuda 1TB 3.5" Internal Hard Drive - 7200 RPM, SATA 6Gb/s, 64MB Cache (Pulled From Dell Optiplex W/ Windows 10 Pro Legacy)

This is a used Seagate Barracuda 1TB internal hard drive, model ST1000DM003.

It was pulled from a Dell Optiplex 3010 or 3020, so it's been tested and works fine—might have some light cosmetic scuffs, but fully operational.

It's a 3.5-inch desktop drive with a SATA 6Gb/s interface, spins at 7200 RPM, and has 64MB of cache.

Transfer rate is 6.0Gb/s, and it's low noise.

It came with a Windows 10 Pro Legacy install, but you'll probably want to format it and do your own setup.

Storage capacity is 1TB (though the specs list 2TB in the raw data, that's likely a typo—it's a 1TB drive based on the model).

It's a Barracuda, so it's reliable for everyday storage, backups, or as a secondary drive.

Made in China, silver color, standard 3.5-inch form factor.

No original packaging, just the drive itself.

Good budget option if you need extra space for a PC build or upgrade.
