The SanDisk Ultra Fit is one of the cheapest USB flash drives you can get your hands on across several different sizes. It's available in 16GB, 32GB, 64GB, 128GB, 256GB, and 512GB capacities. The drive is rated for up to 130 MB/s speeds on every size from 32GB and up, but the 16GB model is only promised to be faster than USB 2.0 speeds.
Prices start at $7 for the 16GB model and range up to just under $58 for the 512GB capacity. The drives are frequently on sale, and the 256GB model reviewed here goes for $29.
