Manufacturer description

The Seagate FreeAgent GoFlex 1.5 TB ultra-portable external hard drive is built around a modular idea: the drive itself stays the same, while the connector adapts to whatever machine you plug it into. Out of the box you get USB 3.0 plug-and-play connectivity, so it works immediately on a modern laptop or desktop with no driver install. If your workflow depends on a different interface, the GoFlex adapter system lets you upgrade the same drive to FireWire 800 or eSATA by swapping the cable rather than buying a second enclosure. The 1.5 TB capacity gives you room for a full system backup plus…

Frequently Asked Questions

Does this drive work with USB 2.0 ports?

The included adapter is USB 3.0, which is backward compatible with USB 2.0 ports, though transfer speeds drop to USB 2.0 rates. Check the product listing for the exact adapter shipped with your unit.

How much can I actually store on 1.5 TB?

1.5 TB is enough for a complete system backup alongside a sizable photo, music, and video library. Usable capacity after formatting is slightly lower than the advertised 1.5 TB, as is standard for all hard drives.

Can I use it with FireWire 800 or eSATA instead of USB?

Yes. The GoFlex design separates the drive from its connector, so pairing it with the matching GoFlex FireWire 800 or eSATA upgrade cable converts the same drive. Those cables are purchased separately.

Does it come with encryption software?

Yes, Seagate preloads backup and encryption software on the drive so you can set up protected, scheduled copies of your files without sourcing a third-party tool.

Is this drive good for Mac?

It connects over USB 3.0 to any Mac with a compatible port, but the preloaded software is Windows-oriented, so many Mac owners reformat the drive for Time Machine. Confirm current Mac compatibility on the product listing.
