# How do I connect an external hard drive to upload custodian data?

Connect, drag, and drop - but beware of older hardware!

⚠️ Beware of older hardware!

USB transfer rates are not all equal, and can dramatically impact time to transfer:

- USB 1.0: 1.5 Megabits per second (Mbps)
- USB 1.1: 12 Megabits per second (Mbps)
- USB 2.0: 480 Megabits per second (Mbps)
- USB 3.0: 5 Gigabits per second (Gbps)
- USB 3.1: 10 Gigabits per second (Gbps)

USB 3.0 and 3.1 ports are more common in modern computers. You should note, however, that it does not always live up to its potential. USB transfer rates are limited by the slowest connected device. Even when two USB 3.1-compatible devices are connected, there is a chance the speeds will fall short of what the device is capable of.
