I work with storage arrays that use up to 180 3TB drives, as part of my
day job. This is using a distributed RAID 1 system.
The key to large arrays of large disks is to reduce rebuild time. The
arrays I work on at work deal with this by using parallel rebuild
methods, and can keep the window manageable.
Personally for home/media library use, I use Raid6. I don't tend to
recommend Raid5 for anything over 4 drives.
I am the type of person that was using Raid1 for standard desktop
systems 8+ years ago, due to the benefits of being able to keep the user
running vs the cost of a cheap hard drive.
Raid never takes the place of proper DR and backup, but if your willing
to kiss your data goodby if something catastrophic happens, it's a good
