THE IRONKEY D300S 64GB
The IronKey D300S is a mid-size USB flash drive measuring 77.9mm in length, 22.2mm in width and 12.05mm in thickness.
Here you can see the D300S right next to the D20402 model (again by IronKey), the SECUREUSB KP by SECUREDATA and the DatAshur PRO by iStorage.
At the top right end of the drive we see the model capacity, an activity LED and a lanyard area.
The serial number of the drive along with its barcode are printed at the rear.
This is a USB 3.0 drive (USB 3.1 Gen 1) so it should be able to produce high-performance numbers.
The protective cap can be mounted at the rear of the drive while in operation (as long as you don't have the key ring mounted).
