Why is the USB Flash Drive actual storage capacity slightly less that the product specification?
All storage products will display a lower than stated memory capacity. The reason is the general used method for calculation of megabyte used by manufacturers:
The calculation for a 32GB is done like this:
32GB=32.000.000.000 Bytes, 1024Byte = 1KB
32.000.000.000/1024= 30.250.000KB, 1024KB=1MB
31.250.000.000/1024= 30.517,58MB, 1024MB=1GB
Therefore a 32GB USB Flash Disk will show 29,8GB under Windows.

My computer only has USB 1.1 ports, may I use the USB Flash Drive?
USB 2.0 devices are backwards compatible with USB 1.1 and vice versa. However, when a USB 1.1 device (host or peripheral) is connected, it will only operate at USB 1.1 transfer rate.
What is the difference between USB 2.0 & USB 1.1?
A low-speed rate of 1.5 Mbit/s (~183 KB/s) is defined by USB 1.0. It is very similar to "full-bandwidth" operation except each bit takes 8 times as long to transmit. It is intended primarily to save cost in low-bandwidth human interface devices (HID) such as keyboards, mice, and joysticks.
The full-speed rate of 12 Mbit/s (~1.43 MB/s) is the basic USB data rate defined by USB 1.1. All USB hubs supports full-bandwidth.
A high-speed (USB 2.0) rate of 480 Mbit/s (~57 MB/s) was introduced in 2001. All hi-speed devices are capable of falling back to full-bandwidth operation if necessary; they are backward compatible. Connectors are identical.
