How necessary is it to use NAS certified drives in a NAS enclosure? This would be a two drive enclosure running in RAID 1.

You can use a standard drives in a NAS if you want, but I personally would prefer to use those specifically designed for that because they have the necessary firmware for such usage.
Basically NAS drives are optimized to use less power, cause less vibration and a specific build-in feature called TLER, which stops the hard drive from entering into a deep recovery cycle. For instance, a desktop drive will try, try and try again to get your data back if a sector's not reading properly and this will result in timeouts, etc. A NAS not be dropped from a RAID array since it will enter in deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area.
Hope this helps and feel free to ask any questions you may have.
If you live next to a Fry's, you can get 4TB coolspin drives (megascale enterprise drives now) for 90 bucks with their coupon every once in a while.
At work I'm using drives designed for 24/7 work and I've never had issues with them ( many clients with 2-4 bay NAS set as daily backup for servers ). Since Seagate isn't reliable enough and Hitachi isn't easily available in my local distribution then I stick to WD RE, Red or Purple. I think I had 1 RMA in past ~4 years so really can't complain.
Out of curiosity what isn't reliable enough about the better seagate drives? They actually carry about the RMA rate as WD...
