Until recently, most hard drives connected with USB 2.0 or USB 3.0 connections, but now many are moving over to USB-C, which offers 10 Gps of transfer speed, equivalent to twice the speed on offer from USB 3.0. Fortunately, hard drive storage is not that expensive to add, and a 4 TB hard drive will set you back less than £200 from some brands. If you are a video editor or a photographer you may want several terabytes of storage. Smaller hard drives have less than 1 TB of storage, not much more than you get in some laptops. These are smaller and more expensive but offer faster boot up for files and programs, ideal for use inside a slim and powerful ultrabook or notebook. The most well-known hard drive brands include Seagate, Western Digital, Toshiba and Hitachi, while others such as Samsung, SanDisk and G-Tech also offer sleek and powerful external storage or solid state drives.
