Performance I/O sec comparisons are great, but there are a lot more important things (IMHO) that can make or break a RAID controller:
How long (time) to rebuild an array?
Was data integrity maintained during an...
-Online Capacity Expansion?
-RAID Level Migration ?
-Power Failure? (Perhaps even a power failure during an OCE or RLM???)
Where is the array information kept? (NVRAM, Disk, or both)
What happens when you simulate a controller failure by replacing it with an identical controller card that has never seen this array?
What happens to the array if the replaced controller has a different firmware version compared to the previous controller?
I would love to see Tom's Hardware step up to the challenge and delve deeper into RAID Controllers. I've seen what your group can do with power supply reviews.
