For what it's worth, I'll play devils advocate and say that you should be fine. I know this question is a year old, but I just found it while looking for information on RAID 1 drives being pulled out and put in another system.
To answer your question, I've had 8x Samsung HD204UI Green drives in a RAID 5 array for over 2 years, and have not had one problem...actually I did, related to a punctured stripe, but that was due to an issue with power loss. The box is up 24x7, for over 2 years straight without one issue. This was with, at the time, 70$ 2TB consumer green drives. Since then, I have upgraded to 5x 3TB 7200RPM Seagate drives, but still use 4 of the 2TB's in a RAID-10 array, and just bought 2 WD Green 2TB drives for a RAID-1 array...all of these consumer drives are so far without issue in 3 RAID volumes in my server.
As long as you have a good controller (I was using a Dell PERC 6/i, now using an LSI 9260-8i), and monitor with a tool like Hard disk sentinel, you should be ok. The drives that others mentioned are rated for RAID arrays, and have added features to make them better choices, but the price point for home users is not justifiable.
Also, since you are using RAID-1, it should be safer as well, since parity is not being calculated, your drives won't get trashed as much as a RAID-5 or RAID-6 array would...raid-1 is mirrored.
