I have had 4xWD Green 1TB drives with RocketRAID 2310 for 3½ years now.
One drive broke quite in the beginning but was of course replaced by warranty, otherwise has been running very fast and reliably all this time.
Now getting more space with these 4xWD Red 3TB drives...ordered already.
Just hoping that RocketRAID 2310 accepts these nicely;-)
I'm going to swap drives one by one and rebuilding the RAID5 between every drive change and then finally have the RAID5 to expand from 3TB to 9TB.
So it will be few days (and nights) job for HTPC on the summer holiday.
