Sudden HDD power outage due to SSD?

Question

Hard disks

HDD WD Gold 4Tb is quite fresh, and there is no half a year. I use it to store files. Win 10 is installed on M2 NVMe, when you turn it off through the "Shutdown", the computer goes out very quickly and starts up again. My questions are as follows:

1. Does the hard drive have time to correctly park the heads? I know that modern drives use recuperation and park their heads on a sudden power off. The question is in what mode it happens.

2.Is parking in the normal shutdown mode different from parking during a sudden power failure. I heard that during a regular power outage, the hard drive manages to apply a braking impulse to the heads and they park without damage. During "emergency" parking, there is no braking impulse and the heads break the seats. Is it so? Or is there enough energy from recuperation for braking?

3. In the Voctoria program, after each "correct" shutdown of the computer, the "Number of sudden power outages" parameter grows. Does this indicate that the HDD can't keep up with the SSD? Also, this parameter grows when the disk wakes up after sleep.

4.How critical is the parking disk in case of a sudden power outage? WD does not provide data on the resource amount of regular parking, not to mention parking with suddenly power off.

Thanks to everyone who will respond!

SMART Data:

Answer 1

In theory, when submitting - shutting down, the PC shuts down everything correctly and turns off
Why does the parameter increase - a sudden shutdown, this question
The disk should be in time in theory ...

Answer 2

1. The run-out time of the disk due to its inertia is many times longer than the time required for parking. Consequently, the "air cushion" between the head and the surface of the pancake is maintained for the entire time allotted for parking.
2. The parking zone is located outside the surface of the disc, very close to its outer edge. Therefore, one should not be afraid that the head will strike the disk when parking.
3. In addition to regenerative electricity, there are other sources of force that pushes the heads into the parking area - for example, the radial component of the air flow velocity vector created by a rotating disk.
Hence the conclusion: your fears are unfounded, even in the event of an emergency power cut.

Answer 3

well, somewhere someone is lying to
the disk for half a year in your work, this is 180 days, abrupt shutdowns 1312
1312/180 = at least seven computer shutdowns per day

Answer 4

SMART in these Gold does not know what it shows. Disk WD2005FBYZ, soon two years from the date of production, a year in the server's RAID array should have worked, the operating time shows 58 days (1409 hours, it may have slept the rest of the time, file exchanger on the film portal 24/7). The number of sudden power outages is 49230, the number of starts / wakeups is 508005. After two runs of the surface test in Victoria with a remap, respectively, 52 errors and remaps and 9 errors and remaps, SMART still shows 0 remapped and pending, although the test graph shows a sharp drop in reading speed to zero over a series of sectors. But SMART Good and the disk cannot be changed.
