How Can I Set Up RAID 5 on My Terramaster D4-320?

Asked by TechieTurtle78
I just bought a Terramaster D4-320 with 40TB of storage for my Plex server, running on Windows 11. I want to set up RAID 5 to start transferring data from my old 8TB drive, but the RAID 5 option is grayed out in Disk Manager. I've checked all the tutorials, but they all show different right-click menus than mine. Am I missing something? Do I need additional software for this? Any help to get RAID 5 working would be awesome!

Have you made sure that your drives are set up as dynamic disks? Sometimes thatโ€™s a key step thatโ€™s overlooked, and you wonโ€™t see the RAID options otherwise.

What model do you have? If your Terramaster doesnโ€™t support hardware RAID, using software RAID over USB is usually not reliable, especially if you're looking for something that can provide data safety. Just a heads up, that setup could lead to more issues down the line.

You'll need to download the configuration software from the Terramaster website. It simplifies the RAID setup process significantlyโ€”just a couple of clicks! It's worth checking out, and it may give you the options that seem missing.

GentleGiant33: I checked the box documentation, and it didnโ€™t mention needing any software, and it claims to be "plug and play". Are you sure it needs extra software?
