Frequently Asked Questions

Is the Seagate BarraCuda Pro 500GB an SSD or a hard drive?

It is a traditional spinning hard drive (HDD). It runs at 7200 RPM with a 128MB cache over SATA 6Gb/s. It has no flash storage.

Will this drive fit in my laptop?

It uses the 2.5-inch form factor and a SATA 6Gb/s interface, the standard for many laptop drive bays. The listing does not give the drive's height, so check your laptop's bay clearance and the product listing before you buy.

What warranty does the BarraCuda Pro 500GB come with?

Seagate includes a five-year limited warranty. You also get two years of Rescue Data Recovery Services, which can help you get files back after a failure.

Can I use it in a desktop PC?

Yes. Seagate markets it for desktops and laptops, and it connects over SATA 6Gb/s. Your desktop needs a 2.5-inch mounting point or a 2.5-to-3.5-inch adapter bracket. Check the listing to see whether a bracket is included.

Will I see the full 500GB after formatting?

Not quite. Seagate notes that available storage capacity may vary, so the usable space in your operating system will be somewhat below the 500GB label.
