The TransMemory U366 USB Flash Drive from KIOXIA does offer great read speeds when picked up with the 128GB capacity, actually double versus the 16GB, 32GB and 64GB SKUs. The writes are around the values we have encountered with other mainstream drives as well, while its aluminum body which has dimensions of 39 x 12.2 x 4.5 (L x W x H) helps with using it along with a lanyard or installed on our keychain.
