Looks nice :D I hope he has better results with Raid5 then me tho. I have reverted back to a dual drive NAS for stability after having raid 5 servers for a long time. Somehow IDE and SATA drives and raid cards don't cut it for me. I have lost my data so freaking often by corrupt arrays it's not fun anymore. The first server I had used a Promise card (Supertrak SX6000) card (with 4 * 80 GB drives) that gave me nothing…

Software Raid-6 FTW.

At 4 platters per drive, I bet the room doesn't need heating in the winter.

Can you actually put one drive physically on top of another like that, long term, without any ill effects from one magnetic field to another?

Next time do try ZFS on Fuse (linux userspace filesystem) - I have a 1TB setup and it works quite well. You could try making a RAIDZ volume and see how it goes.

Have you had good luck with this? I'm running zfs on an open solaris server, but I hate solaris and would like to switch to linux. I never got the impression that zfs on fuse was stable enough to trust with all of my data.

If the magnetic fields were strong enough to hurt a drive a few centimeters away, they would ruin the other platters in the same drive, and the data on the platter a few millimeters away.

Drives get as close as they can in ordinary servers and cases as well.

It would be more common to worry about heat issues, although there's a Google study floating around the net and their findings are that the role of heat in hard disk failure is much less significant than commonly thought.

Uh oh... I see Green Power HDD's. We used them for a while in big Raid configurations and their failure rate is bad.

Always use black HDDs for servers man (if using WD)!

It was a side effect of over ordering (someone typed 100 instead of 10 for a weekly order...) a load for another part of our business.

Never again! We even had to stop using them as long term storage disks just in case... (though it appears heat was the main issue for them)

I use ZFS under FreeBSD 8-RELEASE in a 6x1.5tb raidz2 (dual-parity) and it is rock solid. The benefit of running ZFS under FreeBSD over Linux is that you don't need to use FUSE, as ZFS has been really well integrated with FreeBSD's filesystem layer.

The problem wasn't really the filesystem I think. The card actualyl threw the disks out of the array and then refused to put them back in somehow.
