Dear All,
The hardware guide does address the requirement for power loss protection for SLOG devices very clearly.
As prices for larger NVMe devices with five year warranties are dropping, NVMe pools would become more economical now compared to the recent past. In addition, TrueNAS 12 (core) will provide the capabilities for fusion pools which can include NVMe devices in parallel with HDDs. There, NVMe devices would store small files and metadata, if I understand correctly.
Am I correct in assuming that the need for power loss protection is the same for all NVMe pools and fusion pools as for SLOG devices? In that case, users who will not afford large NVMe devices with power loss protection should stick to HDDs and not pursue the gain in speed, correct? If this is correct, should it be made made more clear in the hardware guide?

Michael Schefczyk
