A noisy but functional hard drive
I bought two of these hard drives for a QNAP TS-433 NAS.
They do the job, nothing special to add.
On the other hand, it's important to note that the read heads are quite noisy during the write and read phases. If your NAS is placed in a room that requires silence, you'd be better off with another model.
Apart from this detail, they do their job perfectly. All that remains is to observe their longevity over the coming years.
