The only 8TB drives around right now are the helium-filled units or the shingled "archive" drives. The He drives are spendy, the archive drives slow and not rated for NAS service.
The 6TB drives are typically recommended. BTW, you can run SATA drives just as easily as SAS. Recommendations are typically the HGST and WD Red drives - Seagate hasn't quite gotten rid of the bad taste in many people's mouths after the debacle over their 2 and 3TB drives.
