If you own a modern laptop with a solid-state hard drive, you must have noticed that they don’t hold as much data as models with conventional hard drives. 128GB, 256GB and 512GB are typical. Larger is an expensive exception. While portable external drives are an option, they are still an extra thing to carry. Another option to consider — if your laptop has a built-in SD memory card reader — is SDXC Memory cards with 512GB capacity. They’re tiny, solid-state, and can double (or more than double) your portable computer’s capacity.
If you don’t have an internal card reader, an external card reader plugs into your device’s USB port. Get a dual one such as the XX so you also have the option of using a 512GB CF card. Although they’re bigger and more expensive, CF cards offer the advantage of much faster read/write speeds, which will affect performance that you’ll notice when opening big photo or video files.
