Segate's FreeAgent series of hard drives are an excellent way to protect your data without the need for a complicated NAS storage device, which is great for beginners who may find working with NAS devices somewhat complicated. The FreeAgent Go is the smallest external drive of its series and promises a multitude of features and topnotch performance at affordable prices. FreeAgent Go is available in three flavors: 80GB, 120GB and 160GB (our evaluation unit) and the only differentiating factor between the three is their storage size, naturally.
