Hello everyone,
I'm thinking about doing some changes to the RAID configuration of our NAS system to improve performance (write performance is priority)
Right now we are running a RAID 5 in X-RAID mode with 4 X 4TB HDDs
My plans is to add 2 X 1TB SSDs in the last to bays and use those for data tiering and hopefully be able to increase performance.
So my questions are:
1. Does going from X-RAID to Flex-RAID cause any downtime?
2. Does anyone have experience with SSDs for data tiering?
Does it increase performance?
What should i be aware of?
When using 2 SSDs should i choose RAID 0 for the best performance and most space, or choose RAID 1 for reliability?
I'd appreciate any input.
Cheers,
Benny

Choose RAID-1. Otherwise you'll lose the volume when the time comes to replace one of the SSDs.
Thank you StephenB
Do you know if going from X-RAID to Flex-RAID cause any downtime?

Normally it doesn't. But I haven't used ReadyTier, so I have no direct experience with that.
