I have the PR4100 with bay 1 and 2 with 3TB drives in raid 0. I want to add bay 3 and 4 with 2 6TB drives. can I do this? Drives are installed. But I am unsure if I can have Raid 0 for bay 1 and 2 and Raid 1 for bay 3 and 4.
Hi @rstaebler,
Please be informed that you need to upgrade your device to Raid 5. But before up-gradation please back up all data from the drive.
Setting a multi drive unit to RAID 0 gives access to the full storage space (ie. an 8TB unit will have approximately 8TB of available space). The negative of RAID 0 is that there is no backup/redundancy of any type. If one or more drives fail, all data will be lost.
Setting a multi-drive unit to RAID 5 requires one drive for redundancy (i.e. an 8TB unit will have approximately 6TB of available space). While available space is reduced, data is protected from a single drive failure.

WD Staff,
Thank you for answering my post. I just need to get one point clear.
Bay 0 has 3TB
Bay 1 has 3TB
Bay 2 has 6TB
Bay 3 has 6TB
Bay 2 and 3 I just added. Bay 0 and 1 are Raid 1. I thought if I went Raid 5, all 4 drives, they had to all be same size?
i was hoping I could do (2) Raid 1 configurations, making 2 storage drives.
I will be using this as Media server (movies and music in our house) Also for backup storage for our PC.
how to proceed?
Sincerely,
Russ Staebler
