I am amazed at how well the product is made, just magically!

In my tests, the drive is connected to SATA-II, so peak line speeds are limited by the interface.
As for the noise - I advise you to make a separate NAS and throw it out of the room, and in the main computer only SSD.

Pros

The volume is like all my old hards combined. No tile entry. Sharpening to work 24/7, 5 year warranty, 1 read error per 1E15 bit (for many 10E14, i. E. 10 times more often), MTBF 2.5 million hours - in theory it should be reliable. Low price per GB relative to all competitors in this class. Minimum heat and power consumption. Lying in its own package (! ) At the bottom of the server without blowing during formatting, it only heated up to 45 degrees. The ratio of GB per watt is generally superb. In smart there is such an indicator as the current level of helium. It won't leak out unnoticed. Maybe. Works seamlessly with older systems that do not support 4kn sectors and PowerDisablePin.

Cons

This applies to all modern hard drives: The real volume is 13 GB. Rounding on such scales is already felt. The speed has grown out of proportion to the capacity. Regarding my 10-year-old hard drives, this one is 2 times faster, and more than 10 times - full formatting takes a day. A RAID rebuild of a dozen of these can apparently take a month. The cost per gig hasn't improved in years. It's just that more expensive and more capacious hard drives come out. If you use it as the only disk, you need to come up with something with patrol read and backups. But I repeat, it is necessary for everyone and always. The durability of helium is questionable. I doubt very much that at least half of such hard drives will be able to work for 10 years. Noise as it should be for a server 7-thousander. In idle time and in linear loads it is quiet, in random access it rattles its heads very strongly. Sleeping in the same room with him is very problematic.
