I bought it for BIOS (UEFI) firmware, with which this flash drive successfully coped. Initially formatted under FAT32, out of the declared 32 GB, 29 are available. Pros: Convenient shape, easy to remove from USB. There is no cap, the flash drive moves apart to protect it from dust. It's pretty tight on the USB port. Different cons: Read and write speed on Windows 10 via USB 3.0: 41 MB/s and 11 MB/s (tested in CrystalDiskMark5.2.1) It could have been higher.
