Which 4TB drives to go in a new XPEnology setup??

Hi,
I've currently got a Synology DS213 with 2 x 2TB WD Red drives in there and I'm looking at setting up a Microserver running XPEnology with 2 x 4TB drives in RAID1 (or the Synology "Hybrid-Raid" anyway - not sure what the difference is to be honest!) Anyway, when I set my original NAS up, the WD Red's were I think the only NAS-centric drives available whereas now Seagate and Toshiba seem to offer them to suit now too!
Is there much between these in terms of reliability and performance?? Any help on the matter will be much appreciated.

Please Help.
Thanks !

I didn't find the right solution from the internet.
