RAID 6 vs. RAID 1+0

I am looking at getting a new server.. which of these would you go with if it will be hosting some Virtual machines?
 
I'm no specialist but do you feel like you would want/need the extra speed that comes with RAID 10. Basically, RAID6 will be slower but can handle 2 failures. RAID10 is faster with the 0 in there but can only handle "1.5" failures.

FWIW, in a similar situation, we went with 10 because of the want for extra speed. We also had 3-4 extra HDDs on the shelf next to the server to hot swap in, in case of failure.
 
you want raid-10

there is a double read/write performance hit that will torch the battery back write cache with raid-6.

spend the extra cash on raid-10 man.


virtualization thrashes the drive i/o. you will feel much pain with raid-5/6.

decent primary storage (aka sas drives) will last years.

hp only sells dual ported drives now (once stock is depleted). this is good on their backplanes they can do dual domain with certain cards so you can have a partial backplane(expander) failure and or drive port failure and continue to function.

things to let you sleep at night.
