RAID 50 Is more capacity efficient and faster I/O it is good for big storages that host database and virtual machine. Raid 10 can be used for servers os boot to protect os crash.

what is better windows or linux? :)I would say that in enterprise segment if you don't know pattern of IO, always use raid 10 because it is more predictable and linear in case of re-constraction, random load etcgenerally

raid 10 is better for databases so OLTP loadraid 50 for loads with low random write intensity, so virtual machines, datawarehouse etcand it also depends on type of disk drives, if you have big slow hdds - 2TB and more, never use RAID 50, raid 10 or 60 is much more preferable in this case

for storage purpose RAID 50  for  good performance RAID 10

It depends on the application type or what is type of data going to be processed, raid 10 give better performance in regards read and write since disk are mirrored then concatenated  example database engines while raid 50  combines distributed parity in addition to striping which is better for data protection.
