Is that memory issue something you experimented yourself?
I had a 750GB mirror running on OpenSolaris at home on 2008 (still using ZFS today and that pool was migrated once to 4TB disks), and I was afraid of the memory thing.
It was never an issue. Even when approaching full disk capacity, never had the memory usage be anywhere near high or even a potential problem. Then had the same server migrated to FreeBSD (OpenSolaris not being maintained anymore) and same experience.
If there ever were memory issues, I was somehow not affected or it was a myth or misunderstanding of how it worked.
