[3dem] RAID question for K2/K3 users

[Morgan, David Gene]

Hi,

We had an issue with a disk in the RAID array on our K3 last week.  It fortunately turned out to be a non-fatal error, but it did make me realize that this is a RAID0 array and that a real disk error could result in troublesome loss of data.

I asked a Gatan engineer who is here installing a system on a new microscope about switching to RAID5 or RAID6.  His comment was that company policy is RAID0 only, but that he didn't see any reason other than a loss in write speed that could result from switching RAID type.

Has anyone changed the RAID on a Gatan computer to something else, and if so, have you had any issues?

Thanks in advance.
