MP 1,1-5,1 Samsung 860PRO SSD very slow as boot drive

[bosDAW]

I have the original Apple brand Toshiba SSD drive in my 2010 Mac Pro 5,1 and was considering swapping this out with a newer drive simply to avoid any potential wear issues. After cloning my system drive to a Samsung 869PRO using disk utility, I noticed the boot time went from 45s up to 75s. It was tested in the same internal drive bay with no other changes made. Is there a reason the old drive is so much faster? Is this a Samsung issue vs Mac issue?

Note that the drive is new but not fresh out of the box. It was purchased a month ago and has been used to make several clone-copies for different backup and testing purposes. I don't know if this means there is data scattered all over the place or if it makes no difference. It seems to work normally otherwise, just a significantly longer boot time that I thought might be a bit faster if anything. Thank you!

Why another thread? Please be a good forum user and don't open multiple threads for the same topic.

Why you write the wrong model of drives? 869PRO don't exits at all.

If you use a NVMe drive, Mac Pro firmware have to scan all the PCIe address space at the POST time and this takes additional time versus just SATA drives installed. More RAM have the same problem, Mac Pro firmware have to test it at POST time. More RAM installed, more time to POST.

SATA drives don't have this scan problem and POST times are always the same. The only variable is the boot drive performance.

Enable TRIM with the trimforce command, non-Apple drives do not enable it automatically.

Just bad typing, very sorry about that. I thought this would be considered a separate issue (boot time versus audio editing), so I did not want to get off topic. I will stick to the original thread if that is preferred. If it is possible to delete a post or an admin wishes to delete this, that is fine with me.
