10TB with USB expansion on Duo V1 possible?
Hi forum members, Based on my searching, it seems to me that the following is possible on a Duo v1 (sparc) but I want to be sure before I expand: I have 2X2tb As raid 0 = 4Tb. The duo has 3 usb...
Data on the duo is definitely at risk. When either internal drive fails, the entire 4 TB array will completely lost. It would be wise to rebuild the duo with 2 volumes (one for each drive). Or go with RAID-1. As vandermerwe points out, you should have a backup strategy.
A better way to reach the 10 TB goal would be buy a new RN104, and start with 3x3TB drives. Then the combined storage of the duo and the RN104 would be ~ 10TB. IF you are ok without raid-5, you could get by 2x3TB jbod (and could potentially substitute an RN102). But the RN104 seems like a better approach - it can be expanded to 15-20 TB of storage with 4 TB drives, and we should see 5 TB drives coming out over the next year or so.
Adding another NAS wil give better performance and more reliability than stringing USB drives onto the duo.
