MDM and RAID config

In my latest class we had a discussion about recommendations for RAID drives in MDM environments. To be honest I haven’t thought through the pluses and minuses of each configuration, but these are my initial thoughts so please feel free to add/comment on them.

MDS: RAID 1 or clone, RAID10: Why: Performance is not an issue. Upgrades and redundancy are critical. When you upgrade you want to be able to go backwards and forwards quickly during 3 hour upgrade windows. No time for reverts and snapshots (besides they are broke in 75.20).
MLM: RAID 5 or RAID 10. Write performance is somewhat critical but not really I worked in a huge MDM environment with multi-gig a diay of logs…but all log servers were on a 100Mb link. Upgrades…who cares, if they screw up DMSs log locally and dump to the MLML later.
Gateways: RAID1/Clone. Performance not an issue. Upgrades are very difficult to want to be able to recover.. Redundancy and single drive failures are also critical.
Smartstations: RAID1/Clone, Same as above.

That’s my world…what is your world?
