Review on High-Speed Data Transfer with SanDisk 128GB Ultra Flair USB 3.0 Flash Drive - SDCZ73-128G-G46 by Michelle Stewart

Overall it's a great flash drive, the read speed is about 140MB and the write speed is 40MB (a bit slower than the 64GB version). It's not as fast as the extreme SanDisk version, but it's the fastest metal drive I've found. You can see the benchmark in the attached image. The metal construction feels solid and will hopefully bang with my keys. My only complaint is that the disc is part metal (silver part) and the key ring part is plastic (black/grey part in the picture). I was hoping it would be all metal, but the plastic key ring feels solid and should hold up over time. Another note is that the drive can get quite hot when transferring large amounts of data, which is to be expected for such a small metal drive, but it's worth noting.
