A solid-state drive (SSD) is a great way to keep offline backups of your files and transfer work between devices. Solid-state means no moving parts and faster transfer times, and SSDs can be both portable or internal. Amazon currently has a Black Friday sale on some of the best SSDs on the market, although the name is a bit misleading — these deals end at midnight tonight. If you manage to catch them though, you can save yourself as much as 60% on your new device. There are some nice HDD deals too.
