Yes, got answers for two questions:
- RAID expansion:
We currently support three RAID migration modes:
1. JBOD to RAID 1
2. JBOD to RAID 5
3. RAID 1 to RAID 5
With the online raid migration, we do not support that yet. This is scheduled to be released in a firmware update in late January.
- Fan speeds:
Our MAX RPM for the fan is 2400RPM.
There are four different fan states (low, medium, high and max), depending on the system temperature the fan will spin according to its preset rpm.
State 1: ~900rpm
State 2: ~1400rpm
State 3: ~1900rpm
State 4: ~2400rpm
When the WD RE drives temperature is at 58-59degC, the fan state is between low and medium state, which is between 900 and 1400rpm.
We do not want to run the fan at high speed as it will cause a couple issues:
1. Stretch the fan rpm that might reduce the lifespan of the fan
2. Create unnecessary acoustic noise
There is no issue with the drives running at that temperature.
