Cost-Effective High Capacity Hard Drives: 8TB Now Highly Attractive
Back in late 2015 I invested in two OWC Thunderbay 4 units incorporating eight 8TB HGST 8TB Ultrastar He8 enterprise-grade hard drives, which cost a pretty penny. Those drives are still serving me well.
Hard drives prices have been relatively stable, but HGST now has a Deskstar NAS series which makes the 8TGB models particularly attractive with 8TB now having the lowest cost per gigabyte versus its 6TB and 4TB siblings—no more cost premium per gigabyte.
Hard drives slow down as they fill up, so even if capacity needs might fit into 6TB, an 8TB drive is a better long term investment.
