When using the QNAP TR-004 expansion unit, you have the option to choose between hardware and software RAID. It's important to note that if you opt for hardware RAID and want to switch between RAID 1 and RAID 5, the drives will be formatted during the switch. On the other hand, if you use software RAID while the TR-004 is connected to your QNAP NAS, you can migrate from RAID 1 to RAID 5 without the need for formatting the drives.
