Hi David,
<div>We had the same issue with our K3 computer. One disk failed, all data was lost. Same response from Gatan. However, you can change it to RAID5 through the BIOS. I can’t remember how I did it, but I managed to figure it out, so it couldn’t have been that
hard…</div>
<div>Speed is clearly not an issue since you can equally well write the images to a spinning disk. At least we didn’t have any problems. That is, until the flood destroyed out microscopes and the K3 along with it LOL (We’re back up and running but with a Falcon
4i now.) </div>

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.<br>

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.</div>

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