Maybe not to a homelab that can just run Unraid and pretend that solves every problem, but at least in the real world.
My UNRAID experience with both has been mixed, with these being snappier to respond to network file access, but wondering what others feel is best in a home media/docker server environment with average use.
I ask because I'll be running 4 of them in my NAS, and I happen to measure Wattage used per every appliance in my home, it gives me a very accurate estimation of my Power Bill and keeps me from entering higher Billing Tiers from the Power Company.
Not to mention, more power used = More Heat, so just wondering what to expect with Four Server Driver @ 7200rpm compared to my Four WD Reds @ 5400rpms.
Thanks!
Thanks again!
It would be great if they would allow some RPM choice below 7200rpm but there simply isn't any.

Pretty sure the PSID for this family IS a 20 digit string.

Just to clear things up, the EPC Idle/Standby states don't save power when the drive is active, only after it has been idle for a predetermined amount of time. Some Seagate drives have a feature called PowerBalance, which can reduce active power consumption but it can have a significant impact on certain kinds of performance, for a relatively small power savings. I'm not a fan of that feature and always disable it.
It's worth considering how active your drives are. I don't know what you're using them for but most hard drives spend the vast majority of their time idle. For that reason, I weigh idle power consumption more heavily than the active numbers. As I mentioned before, if your drives spend substantial swaths of time idle, the EPC states can put them in a lower power mode, saving more energy. Be aware, you may also have to tweak some settings to prevent programs querying their SMART status from waking them up.
Depending on how you look at it, the numbers could be far more appealing for the Ultrastars. Your current drives are only 4TB. Even if they use twice the power, one of these Ultrastars could replace three of your old drives. Per TB of storage, you'd be using less power. I know that may not be the only concern but it's worth considering.

Slower speeds generally mean less noise, power, and performance, but for write-once/read-many applications where the drive is already plenty fast enough, especially as data density increases and leads to faster throughput.... that's totally fine.
I think a lot of people who just serve media would choose the lower RPM drives if they were able to make a choice.
But that's not a thing so whatever. I just want to put a stop to all the people posting about modern large 5400rpm drives, because someone will believe they exist and that just complicates the current landscape needlessly. You have no choices regarding that specification anymore.
Besides, unless you have a fair amount of Cams AND are doing non-default constant recording, a 1 or 2TB drive should be more than enough in a Eufy Homebase.
One user calculated that with 7 Cams, a 2TB drive would give him 32 months of footage.

These are perfect for adding to fault-tolerant arrays, since the cost per TB is very cheap.
If you care at all about your data, you should also have backups in addition to hot spares/parity drives in your arrays that are helping with high availability. RAID/spares/parity is not backup.
And for backups, 3 is 2, 2 is 1, and 1 is none.... As they say.
Out of curiosity, did you run a full test on the drive before using it? Most of us who buy these will try to prevent against immediate failures when in our possession by running overnight testing. These drives are essentially a lottery, possibly due to handling during shipping, but probably just because no company is doing much testing of stuff they sell as "refurb".
Refurb means "I get to thoroughly test it" in my experience. As long as the price is right, I'm game.

Not judging either method, just wondering.
