I currently own five of these.
If that isn’t a recommendation I don’t know what is.
One of the problems with recommending a specific disk drive is that drives change, capacities increase and what I might tell you
about today may not even be available next year. The external drive I recommended some years ago is no longer even being made.
With that having been said, today the FreeAgent Go is an incredibly handy and valuable device.
The version I use has a capacity of 500 Gigabytes, all in a package that’s smaller than a paperback book.
One of its most appealing features is that it does not need an additional external power supply; this model is powered completely via its USB connection. As a result, it’s perfectly portable. One of my five drives sits in my backpack for backup as I travel, for both data and photographs I take when on the road.
I use the other four for data storage at home.
Even though these drives are small and rugged, I take no chances. Since they’re relatively inexpensive I actually have them set up as two pairs: one drive of each pair as the “primary”, or drive that I actually use on one machine, and the other as “backup” on another machine, mirroring the primary via a script run automatically each night.
Now, while the drives are small and portable and convenient and relatively inexpensive, they’re not particularly fast. They’re perfect for backing up, for portability, and for redundant data storage, though, and that’s exactly how I recommend using them.
If you’re wondering what kind of external drive to get for your backups, it’s hard to go wrong with the Seagate FreeAgent Go 500GB external drive.
I recommend it.
