| How to Spec MySQL DB Server Requirements
How do I make sure I buy the right hardware for the job? |

I'm trying to ask this in a way that allows other people to learn from the responses rather than just answering the question for me.
When trying to determine hardware specs for use with a machine that will be a dedicated MySQL DB server what factors should be considered? And how do you determine minimum hardware requirements to assure a responsive machine without overpaying? (Why buy a $10k machine when a $1k would suffice.)
CPU(s), RAM, Storage (RAID vs SSD vs stand alone drive).
I'm sure the size of table(s) and interaction with table(s) are impacted by DB type as well.

RAM is important, and SQL will want to use as much as possible for caching. Get as much RAM as possible.
CPU is not a huge deal, something mid-range will be fine.
I would suggest Raid 6 with SSD's.

These are some of the considerations:
1: Will the database(s) be mainly read only?
2: If read/write, what is the projected numbers of writes and the read/write ratio?
3: What is the size of the indices?
4: What kind of traffic will the server have to cope with?
5: Will it be running as a single server or as a master with slave servers?
6: What kind of backup protocols will you need?
