(Same as mine). You DO NOT want to be running raid 5 or 6 on these things !!!! They're desktop drives not meant for raid. They do not support ERC. *One* *soft* failure on these and you run a good chance of trashing your array !!!! Make sure you've got your raid timeout increased - there's plenty of threads about how to do it - otherwise one disk hiccup for any reason is likely to cause a cascade of failures !!!! You need to upgrade them to Western Digital Reds or similar asap. Cheers, Wol
Hi Wol, Yes, these are the 3GB Seagates. They have been running 24/7 for about 3 years now. I lose a drive occasionally, replace and rebuild. I will consider the REDs for the next time I do an upgrade - I imagin I would have to replace all 7 drives at once. How about the Seagate NAS HDDs? I will look at the the raid timeout. Thank-you for the tip. - Justin
