Problem: My file transfers are too slow
Q: Are both ends of the USB cable firmly attached?
A: Review troubleshooting tips for cable connections below:
Check both ends of the USB cable and make sure that they are fully seated in their respective ports.
Try disconnecting the cable, waiting 10 seconds, and then reconnecting it.
Try a different USB cable.
Q: Is the hard drive connected to a Hi-Speed USB 2.0 port on your computer or hub?
A: If your hard drive is connected to a Hi-Speed 2.0 port or hub, the inferior performance is normal. LaCie
2big RAID performance will improve when it is connected to a USB 3.1 port or a SuperSpeed USB 3.0 port.
Otherwise, the device operates at slower USB transfer rates.
Q: Are there other USB devices connected to the same port or hub?
A: Disconnect other USB devices and see if the hard drive’s performance improves.
Problem: I have an older computer with USB 2.0 ports
Q: Will my hard drive’s USB 3.1 Gen 2 port work with my computer’s USB 2.0 port?
A: Yes, the cable end that plugs into the computer (USB Type A) is compatible with both USB 3.0 and USB
2.0. Make certain to use the included cable with the correct USB Type A connector. However, the transfer
rates are much slower with USB 2.0.
Problem: I must use a USB hub for my USB devices
