Anyone running Raid Ten?

[johnics]

I am considering changing to Raid ten instead of Raid 5 on a dell 2550 with a 220s array. Any knowledge or concerns out there?

We use RAID 0+1 (which I think is referred to as RAID10 sometimes?). It's probably the best RAID to use where performance is key and you also want good redundancy, it does use a lot of disks though.

Hi,
a raid 10 is a stripe of 2 or more mirrors, its probably the best available for data storage as its very unlikely that everything will go down at the same time, however it uses loads of disks and so is very expensive to set up even a small container. Unless the data you have is really really important a raid 5 with nightly / weekly backups should do the trick

Depends on the type of data that you are putting on the Disks. If it's something like SQL Transaction logs RAID 1+0 is about the worst thing you could use as SQL Transaction logs only do sequential writes.
