How to Choose a Hard DriveUnderstanding how to choose the right HDD for gaming, video recording, server, and other tasks
Turned out to be a not bad hard drive overall)))
22 November 2021 
For those experiencing "HDD didn't start upon first launch," don't rush to conclusions! Go to "Computer Management," "Disk Management," and there you should be prompted to partition the new hard drive. Choose, for example, GPT, create a volume, and voila, no need to go to the service claiming the disk is DEFECTIVE)))

You'll have to get used to the periodic knocking), I bought it on 18.11.2021 for 33,299 ₽ with a discount...
The hum of the disk can be resolved by placing a sponge underneath without fastening it to the case. If you attach it to the case, and mine is made of foil, then Mozart's melodies become second-rate))), yet silence is gone((( since the periodic knocking is like having a woodpecker settled in your system unit!

The program "Victoria 5.23" showed that 6 blocks take 1 second for access, and 46 blocks take 250 milliseconds, a slight acceptable defect)
- Quite capacious enough to cram your entire life in photos onto one hard drive)))
- Good write/read speed: 250 Mbps
- Huge buffer, 512 MB
- When connected, it showed 18,000,189,054,976 bytes
- The writing method is ePMR, which I consider the best
- I got the WUH721818ALE6L4 model, had no issues, just connected the power and SATA cable, PC recognized it without trouble
- Helium inside the case is a big plus
- HDD temperature without load is 42 degrees at a room temperature of 26
- Average speed, for example, is closer to the spindle around 120 Mbps
- Output in OS Windows (binary system) will show you that the disk is 16.3 TB
- With GPT, NTFS, the hard drive will occupy 6.37 GB just to partition the disk without your permission))))
- The noise is just horrible as if a plane is constantly flying (it's really annoying) forget about silence. I have AeroCool Flo Saturn case, two hard drives touch each other, resonate, and increase the noise, or maybe it's just the model I got...
- Every 5-10 seconds during access, there's an unpleasant loud knock, clearly exceeding the "Noise level during operation 36 dBA", it's like someone constantly knocks on your apartment door, and you open it, but no one is there), on the internet they say it's normal, but believe me, I'm shocked by this hard drive, it's irritating... when your PC case near your feet is constantly knocking... it doesn't affect work...
