Well, the WD Reds are usually pretty good.
Seagate NAS (aka "Ironwolf") drives are a good option.
If you want cheap, large capacity storage, Seagate Archive drives are fantastic, but they have some poor write performance.
Looking for recommendations for 6TB+ HDDs. I am running WHS 2011, no Raid, server is left on 24x7. Mostly used for media streaming and client backups. Had a WD 4TB red fail and the RMA replacement from WD is showing SMART CRC errors after 4 months. Thanks!
