With an external hard drive of 1TB, you can safely store documents, photos, movies, and music. For example, you can store 42 HD movies of 1.5 hours or more than 100,000 photos on a 1TB external hard drive. Due to its small size of 2.5 inches, external SSDs are easy to take with you to the office, a friend's house, or on vacation. The advantage of an external SSD is that transferring files goes much faster. For example, an SSD transfers your files 5 to 20 times faster than an HDD. You can easily connect an external SSD to your computer or laptop using a USB cable.
