Review on Samsung BAR Plus 128GB - High-Speed USB 3.1 Flash Drive Titan Gray (MUF-128BE4/AM) by Micha Kochaski ᠌

Capacity 239 honest gigabytes. Linear read speed is 300 MB/s, write speed is 110 MB/s, and for the entire length of the drive, and not just for the cache size. Heats up moderately during operation. The case is one-piece, which means nothing will break or be lost, however, the contacts are not protected, so over time, debris can fill up in the cavity. But in fact the only obstacle to owning this device is the price. If it doesn't bother you, you should take it.
