using multiple drives
why wouldn't you?

I'm from a MS SQL shop, and i know things are a little different on the MySQL side of the world, so I am trying to learn as I go.

Let's say your MySQL setup has 2 hard drives:
- 20G partition on a SATA drive (slow)
- 140G partition on a SAS drive (fast)

Is there any reason why you would NOT want to have all your data files on the SAS drive from the setup?

And even assuming you originally set things up with just the SATA drive (later added the SAS drive), is there a compelling reason NOT to move the data files to the SAS drive?

Note- the server is not yet in production. So shutting down MySQL and moving the files will not affect any users.

I cannot speak to this question personally but have a look at this PDF from Percona
[percona.com...]
Let me know what you deduce!

I may or may not need to have alcohol involved to make a deduction. ;)

Interesting page- it's going to take a while to absorb it all. Thanks!
