I'm going to buy my first drives for my Terramaster D4-320. I will be buying manufacturer recertified from serverpartsdeals as they seem to have an excellent reputation.
Later this year I plan to install 3 Reolink camera's with an 8 Mbps bitrate. I've calculated that I need about 15TB of storage for video storage and my media needs (arr server setup with Jellyfin). I will have 20TB in ZFS Z2. A bit more than I need but properly sized enterprise drives are out of stock, or not a good spec on the website.
I chose the HC510 for helium-filled and reliability. They will be in a dry basement that's cool all year round and noise is irrelevant.
Now I don't plan on buying all 4 of them immediately as I don't have the camera's yet and losing my media is acceptable at this point in time. Will I be able to buy 3 more HC510's later on and if not will there be compatibility issues with other 10TB drives in ZFS?
I'm still new to the whole data storage and home server landscape and just going off what seems to be generally accepted as good hardware.
I've looked into new WD Red Pro's too but they're more expensive new for less. They're also out of stock recertified and I have no idea how often they're restocked seeing as how they're not enterprise drives.
EDIT: seems like HC510 is helium too, so might pick those. I replaced the HC520 in my post.
