Hello, please suggest where to buy trays for n5200.
does anyone use raid1 with n5200? what is your impression / experience? did you try to switch hdds to test it? how long it takes to rebuild the fresh disk inserted instead of removed on?
i hope to use it as a form of back up solution. anyone comments on this?
Thank you.

Hi.... I understand you wish to create a raid-1 and then just break the mirror by removing a disk with data. That should be possible, but I don't think the 5200 is ideal for that. * there are five slots in the 5200 * i think a raid 1 can only be built on two drives (not 100% sure about this) * 5200 only supports one raid-array per box That means you will be able to create an array on two drives. And the remaining three can only be used for hot spares. Based on this a 5200 hw with three slots would be better (assuming it costs less) From my experience which only spans raid-5 with 5x750GB drives, the rebuild-time by replacing a disk could range from 20 to 40 hours. * smaller drives would of course be faster * raid-1 is alot simpler than raid-5, so it should be alot faster as well. guess others have an opinion on this and can correct me if I am wrong.

* i think a raid 1 can only be built on two drives (not 100% sure about this) According to specs, RAID-1 can be built on any even number of drives, (ie: 2, 4, 6, 8, etc). As long as there is always 1 source drive and 1 mirror drive, it will work properly. So you should be able to build a 2x2 RAID-1 array on the 5200, and have 1 extra drive in the system as a "hot spare". I suppose it would be safe, but personally, I'd think that a RAID-6 would be more efficient and still allow for 2 drives to fail before being in danger of losing data. please suggest where to buy trays for n5200. i hope to use it as a form of back up solution. anyone comments on this? I think you'll need to buy trays directly from Thecus. As far as using it as a backup solution, I think it would work wonderfully. I use mine as a RAID-5 backup, and have it back-up computers over my network nightly. There were some issues with earlier firmware, but on the version I'm running (.08), it's pretty much rock solid (up-time of 1 month right now, with no issues).
