Ways to improve performance with drives in RAID 10

Have a look at galera cluster if you haven't already. It's very easy to setup and never had any issues.

Even better with Percona XtraDB Cluster, which uses Galera

Seriously though I don’t think I’m going to do hardware RAID on any new server ever again. I’ll shout from the mountain tops for everyone else to avoid them where they can, performance be damned. They cause more damage when they fail, and you have to keep compatible spares on hand. I always thought HW RAID10 failures were a lie and everyone who claimed them was a liar covering for their own failures. Oh to be young again. Sorry that was unrelated 🤣

@jar for a new setup I have been planning a raid10 in production and a much cheaper raid0 with lesser number of drives as incremental backup: isn't that an ideal setup with the caveat that in case of raid10 failure u go straightaway to the backup? if raid10 isn't a good option then wt shud one go for?

You never use raid0 when you need reliability. You only ever do raid0 for performance reason.

Nice article, thanks. In the meantime I have done some tuning on the system for many things, and it's pretty smooth! It doesn't feel like it's hard drives so I'm happy
