Low Level USB Benchmark

The low-level USB benchmark utility measures the read / write speeds on a sector level. This test provides USB performance and shows the best possible transfer rate the device could obtain.
Testing the read/write speed at a sector level means there is no overhead with reading the File Allocation Table [FAT] and thus pipes the best possible transfer rate of bits passed over the Universal Serial Bus.
The low level USB benchmark feature will be the most accurate way to test your flash memory device and it's ability to read and it's ability to write.
Note: this test will work with all Mass Storage devices, such as SD media, microSD, miniSD, Compact Flash etc flash storage.
