Hibernation for SSD: harmful, beneficial or neutral?

Question

Iron

I welcome everyone!
Not so long ago I bought a glorious ~ 256 GB Samsung 850 Pro SSD, connected it to the SATA III port via the AHCI mode of my laptop, and installed a ~ 700 GB hard drive using a sled in place of the DVD drive to SATA II IDE. It turned out to be a good bunch of ~ 900 GB (taking into account the Over-Provisioning 25% I installed on the SSD). Everything works, it would seem, not bad, but I ran into a number of issues. Two of these are the effect of sleep/shutdown on an SSD.
Interested in the following points in the Windows power schemes:
1. Sleep after... Tobish normal sleep in Windows, hibernation is not used (disabled via the command line).

2. Turning off the hard drive (or even SSD) after a specified period of time.

As far as I know, AHCI means support for high performance modes and low power modes, but the SATA II port of my laptop does not support AHCI mode, and, accordingly, a hard drive with this type of connection does not have a low power mode and for it this issue may well be reasonable. So how to be? Is there any detriment to stability, reliability, longevity, or performance in the top two lists for SSDs? Is there any benefit from them in this bunch of SSD + HDD? Or is it debatable?
PS The reason for the question is articles on various resources that recommend completely disabling sleep mode. One of the reasons for such a solution is the work of TRIM during inactivity. Isn't it dangerous for the safety of data to turn off the power of the SSD using Windows during such operations?

Answer 1

It is not dangerous, not harmful, and not helpful.
But there is not much point in this - the SSD is in sleep mode most of the time, unlike the HDD, it does not need to turn the pancakes.
Therefore, when the SSD is not being used, it already has minimal power consumption.
Well, garbage collection goes just during downtime. Therefore, he will have less time for the work of the garbage collector - and this is both trim and cell reassignment.

Answer 2

Install the original utility from Samsung for SSD (I have the same ssd) - it knows how to properly configure everything you need
