Today only, Best Buy is offering one of the absolute best 500GB external solid state drives on the market for just $79.99. You could use the Samsung T5 500GB External USB Type C Portable SSD to backup files, store media, or probably a dozen other lame things, or you could plug it up to your Xbox One or PlayStation 4 to add an additional 500GB of high speed game storage.
Important specs include a USB C interface, transfer speeds of up to 540 MB/s, and AES 256-bit hardware encryption.
