ejecting the 2.5" hdd + USB3.0 enclosure case in windows 10 is considered:

Active (operating) Tracking Rotating Full powerIdle, performance Tracking Rotating Self refresh—low power Idle, active Floating Rotating Self refresh—low power Idle, low power Parked Rotating Self refresh—low power Standby Parked Stopped Self refresh—low power Sleep Parked Stopped Self refresh—low power

And your question is.....?

And whatever the answer (from the manufacturer) might be, of what use is that 'answer'?

Old HDDs from 2013 have outdated firmware and an older processor. Will this impact the parking speed after ejecting in Windows 10 the 2.5" HDD + USB3.0 enclosure case?
My models are: WD10JPVX-08JC3T5 and HGST HTS541010A99E662

I asked twice in WD chat about these two 2013 models and they gave different answers, first: old units with old processor and old firmware to enter parking after ejecting from Windows was 10-20 seconds
Second chat: they said that these models enter parking after ejecting from Windows in milliseconds

Overall, what difference does it make, to you?

Very old 2.5" HDDs (2013) older processor and older firmware take 10-20 seconds to enter parking after ejecting in Windows 10 case USB3.0 + hdd?

Have 2.5" HDDs undergone any hardware firmware modification to reduce the time to enter parking after ejecting (safely removing hardware) in Windows? If so, when was this fix implemented?

Has the overall functionality and speed of 'parking' changed since that was first built in to drives in the 1990's?
Almost certainly yes.

Has a single particular make/model been updated, in its lifespan, to reduce the parking time?
Probably not.

It is relevant because if the 2.5" hdd + case usb3.0 hits the table before parking after ejection in Windows (safely remove hardware) there is a risk of the reading heads touching the magnetic disks, so finding out this information is very important.

No, you asked if it had changed over the years.

The only relevant thing is what it is now, with the drives you currently have.

Modern voice-coil actuated hard disk drives are all auto-parking. On some disks, a weak spring is attached to the head assembly that tries to pull the heads to the landing zone. When power is applied the actuator is able to overpower the spring and position the heads normally. When the power is shut off, the electromagnetic force from the voice coil abates, and the spring yanks the heads to the landing zone before the platters can spin down; this can sometimes be heard on older drives as an audible clunk when you turn the power off. Other disks use a different mechanical or electronic scheme to achieve the same goal. Some even make use of the rotational energy remaining in the spindle motor to move the heads off the data surface when the power is cut off! This means that modern hard disks will automatically park their heads–even in the event of a power failure–and no utilities are required. The BIOS landing zone parameter for modern drives is ignored.

I do not know what specific tech your drives use. (and 2013 is not "old").

It is really very difficult to get technical information about old 2.5" HDDs from 2013, even with Western Digital for the models WD10JPVX-08JC3T5 and HGST HTS541010A99E662

Example: how long do these models + USB3.0 case need to park the heads after ejecting (safely removing hardware) in Windows

The Windows eject (safely removing hardware) option cuts off the electrical current through USB3.0. Is this why the 2.5" HDD + USB3.0 case is parked?
