RAID 5 vs RAID 10 for reads

I know RAID 5 has a slight performance hit when it comes to writes but what
about when comparing RAID 5 to RAID 10 when it comes to reads ?Hi Hassan
The number of Read I/Os supported by RAID 5 and RAID 10 are the same
i.e The number of drives in the array X the number of I/Os per second that a
drive can handle.
You may want to read the comparisson of RAID levels in Microsoft SQL Server
