If you need to transfer a modest amount of data, a flash disk will do just fine. An external hard disk is large enough to let you backup your whole PC, even though it's similarly compact and portable. The disk HyperX Savage EXO SSD 960GB is a SSD. The acronym SSD means Solid State Drive, or a flash memory based disk. It's much faster than the common hard disk and consumes less power.
External SSD drives are comparably more expensive than standard magnetic HDDs. Basic PC software plus some work-related documents will fit on a 64GB drive, though 128GB would be ideal. If you plan to save movies on your SSD, even 256GB could be too little.
SSDs often feature disk reading speeds of about 500 MB/s and 480 MB/s write speeds, which is considerably faster than standard HDDs. The data transfer speed is also influenced by the connector type, for instance, USB 3.0 will always beat USB 2.0. This external HDD uses a USB 3,1 (3,1 gen2) and USB-C connector.
