These traditional hard drives have largely fallen out of favor for use as system drives, but their larger capacities and much cheaper per-gigabyte cost means they are still a very popular choice for external storage use.In recent years we have witnessed the solid-state drive revolution. These have moving disks (called platters) inside, where the data itself is written and read. Most hard drives, until recently, were mechanical HDDs.

These could be worth the price if you need the boosted storage of an HDD but expect to actively read and write to the external drive a lot. These hybrid drives are essentially HDDs that feature built-in flash storage (usually a fairly small amount) where your most-used files are stored and read, combining much of the responsiveness of SSDs with the larger storage capacity of HDDs.

Make sure your external hard drive uses at least USB 3.0 (which is about ten times faster than USB 2.0 by comparison). The fastest read/write speeds will be bottlenecked when transferring data over a connection that uses an older standard like USB 2.0. Solid-state drives naturally offer the best read/write speeds, but, as explained above, offer the least value per gigabyte.Also, don’t overlook connection speeds.
