X-Raid Replace Failed Disk and optimize performance
Question: Considering the relatively new RAID configuration 'wizard' in FW 6.10.2, is there an option to optimize performance of my system which currently uses X-RAID with 6 x 4TB disks? Backgrou...

You could potentially look at SSD tiering (metadata-only or metadata+tiering). That would require two slots for SSDs.
But if you have the slots, you don't need to start over - you can just switch to FlexRAID and add the tier.
Netgear has adjusted the on-disk structures (quite a while ago), so if your volume is very old, you might find you get better performance if you start fresh.

Since the Pro Pioneer has only SATA2, I expect the gain from data tiering will be minimal. The drive caddies also don't accept 2.5" drives natively, and there are only a few compatible adapters available.

Well, there is still 0 seek time, which will improve performance for some things (for instance data base access).
But I agree that mounting the SSDs is a problem.
Thank you both for the pointers. I had forgotten the SATA 2 limitation. I will stick with status quo.
