I currently have two traditional hard drives in my system, a Seagate 2TB for documents and an old Seagate 500GB with media for Plex. Today, after noticing extremely slow transfer rates, I found that my 2TB drive is dying according to Seagates SeaTools. I am thinking of replacing both drives with a single 3-4TB. Any recommendations on brand/model?? HGST seems to be the most reliable but I didn't know which model would be best. It will only be storing local copies of cloud stored documents as well as media.
