I'm not sure if I have a defective drive, but this USB flash drive does NOT support high speed data transfer. It reads at around 26MB/s and writes at an average speed of 5MB/s. I have included the CrystalDiscMark of this disc, the write speed test# may not be accurate as it took 7-9 minutes to actually copy the 3GB file. Also included is the CrystalDiskMark of my ScanDisk Fit USB drive for comparison. So it's not super slow when writing data. I'd say a good drive for the price. If you need high read/write speeds, this drive is not for you.
