@OuttaJoint if you have the HighPoint RR4522 you will need to download the latest firmware from our website
@OuttaJoint Capacity is determined by the type of raid controller you are using, what raid card do you have?
@OuttaJoint G-Speed eS Pro uses HGST Ultrastar hard drives and firmware should not be an issue when replacing all 4x hard drives.
@nypldance A quick search for "External Hard Drive Foam Storage Case" will get you some good results

G-SPEED Q - RAID Configurator

Using the G-Technology configurator, you can change the RAID settings to either RAID 0 (Stripe) or RAID 5 (Redundant Stripe). The RAID 0 setting will allow for an increased performance across both drives and display the maximum capacity available. The RAID 5 configuration allows you to write partial data across all drives. For example in a G-SPEED Q with 1TB (x4) drives, the end capacity would be 3TB of storage. The "missing" 1TB of space in this example is used to hold partial amounts of data in the event any 1 drive in the RAID fails.
