I have two Seagate Barracuda ST31000524AS 1TB hard drives setup in RAID 1 and there is no data on the drives (besides what Alt-F has put on). I decided to perform a RAID check (Disk Utilities->RAID operations->Verify) before loading on all of my data, but it seems to be taking an unusually long time to run... It's been running for about 18 hours and says that it still has about 12 hours to go... Is this normal?
As well, I see that there is an option to schedule a RAID check using System Services, is this the same test? I can't imagine wanting to run this check on a production box as it seems to bring it to a crawl and for a very long time as well...
Thanks.

Yes, every byte of your disks are being verified against the other, doesn't matters if they have meaningful data on them or not.

No, it just checks the current RAID status and e-mails you on any event.
