Based on your setup and requirements, here's a breakdown of your options:
Creating New RAID Groups:
Option 1: Creating two RAID 5 groups (3x18TB and 3x16TB) would indeed result in RAID 50. This configuration offers better performance and capacity utilization compared to RAID 6.
Option 2: By adding new RAID groups, you ensure that each group utilizes the full capacity of the larger 18TB drives, maximizing storage efficiency.
Adding to Existing RAID Group:
Choosing RAID 5 or 6 for the existing RAID group would result in combining the new 18TB drives with the existing 16TB drives. However, the additional capacity of the 18TB drives may not be fully utilized, potentially leading to wasted storage space.
RAID 5 would provide more storage capacity (71.68TB) compared to RAID 6 (56.25TB), but it's important to note that RAID 6 offers better data protection with dual parity.
In your case, considering the need for storage efficiency and performance, creating new RAID groups (Option 1) seems like the better choice. RAID 50 offers a balance between performance and redundancy, especially for a home NAS environment with multimedia files and remote access.
Regarding speed, RAID 50 typically offers better read and write performance compared to RAID 6, especially for sequential access patterns like media streaming. However, RAID 6 provides better data protection due to its dual parity scheme, which might be beneficial for hosting important data like photos and videos.
