If you have a 4-bay and you need the best performance with 2 drive redundancy then RAID10 will be the best choice. But if you do not relly on best performance as IOPS then there will be very little difference in which RAID to choose since you are limited toa 1GbE speeds anyway. Internal drives will operate at 200MB/s each.RAID6 will be as fast as SHR2. With RAID6 you will only get more capacity when you finish replacing all drives. SHR2 will add additional storage after replacing 2 drives.I hope this helps https://www.synology.com/en-uk/support/RAID_calculator
