Significant performance issues with RN214 since firmware upgrade
Model: RN214
Firware: 6.9.3
OS: Used with both Windows and MAC OSX
Config: 4 disks (2 x 3TB + 2 x 4TB) RAIDed to give total of 7TB

Have you looked at the ethernet stats in the log file zip (network_settings.log)?
Are you using link aggregation? If so, which mode?

XRAID would give 10 TB. What RAID mode are you using?
Thanks for the response - the network settings file is attached. There does seem to be quite a lot of dropped RX packets on the Ethernet. It is using X-RAID although it set itself up with 2 RAID groups so 6.34TB maximum is configured

XRAID would have two RAID groups, but would still would give a 10 TB volume. One RAID group would be 4x3TB RAID-5 (9 TB), the second would be 2x1TB RAID-1.
So if you are only seeing 7 TB with XRAID, then something must have gone wrong with the expansion. Two FlexRAID RAID-1 volumes would give you a total of 7 TB.

Yes. I suggest
- trying a different ethernet cable
- trying the other NIC port on the NAS
- trying another switch port on the switch or router.
I have tried those and unfortunately is makes no difference.
