Whith reading there i no parity checking in RAID 5. Also note that the RAID 5 write overhed depend on the RAID controller. For example, the RAID5 DP in VA arrays is has a very high overhead but, there is no significant preformance improvement with the EVA Vraid1 compared to Vraid5.

As per my knowledge, RAID5 degrades some performance due to parity checking and our database has been running extremely slow. Is RAID0+1 is right candidate to implement? can RAID05 be converted to RAID0+1.<BR /><BR />Waiting for reply.<BR /><BR />Mehul Thu, 10 Mar 2005 02:32:04 GMT https://community.hpe.com/t5/disk-enclosures/performance-benchmark/m-p/3501588#M15529 mehul_3 2005-03-10T02:32:04Z https://community.hpe.com/t5/disk-enclosures/performance-benchmark/m-p/3501589#M15530 Hi,<BR />RAID 1+0 may give some performance benefit but mostly if your database is very write intensive.
