It's as quiet as I expected. However, it does make a bit of noise when it starts up or when it wakes up from standby. Otherwise, there's nothing to complain about, so you can buy it with your eyes closed if you need a lot of storage.
Speeds of 250-280 MB/s for backing up large files from an SSD (the speed drops very sharply for very small files, but this is usual for a hard disk), in line with the tests that can be found on the Internet. I didn't notice any problems after an initial copy of around ten TB.
Used for data storage on a desktop PC.
18.1 terabytes of memory available in reality, but apart from that, everything's fine. Quick and easy installation. I don't get the impression that it's particularly noisy. It remains to be seen how it will evolve over time.
With the purchase of my Synology D220+ for the moment it's going very well !
Even if I had not seen that this Hard Disk is not too much made for a NAS use
It still works fine just a little noisy when you do transfers but otherwise top notch
