Comment on https://nascompares.com/wd-red-pro-vs-wd-gold Two reasons I choose WD Gold over WD Red Pro. (1) WD Gold runs about 10 deg F cooler – may lead to longer drive life. This is from having them in the same enclosure for months before I fully switched over to Golds. (2) In a RAID5 array, which is probably the most common config for home NASs, the time when the array is most stressed is when the array is rebuilding, either due to adding/swapping a drive for a failure or upgrade. WD Golds are designed to be continuously hammered in a datacenter environment so the stress from rebuilding is essentially the standard design parameter for this drive.
