I have one of those on my laptop. They are just a interface to connect the drive SATA connector to the laptop SATA connector, like a bridge.
You may have a SATA 300 (SATA 2) but the bottle neck is the HDD. Laptops HDD are slow (sometimes less than 100 MB/s).
Did you test the drive speed with a benchmark software? I suggest to use CrystalDiskMark It is a portable, dont need to install. Extract and run.
I just checked a Dell Latitude E6410 that has the easily-removed CD/DVD drive [it's thinner than the D810] and compared it with a 2.5" SATA HDD, the power and data cable sockets on them differ from the other so the caddy must have an adapter to change the sockets, could be something not exactly right with that adaptation that can cause the slowness. Again, since the hardware is the same does the same issue occur on both the Windows installation and the Mac installation? In other words, is the problem only with Windows? These are things necessary for diagnosing, rule out hardware or software.
Well, what do you think is the problem? It is said because the voltage is not enough in a few places.
I can throw the photo of the hdd if necessary

As a result, this write speed sometimes increases, these values must be at least 106 MB / S.

I have a MacOS operating system on my computer, I can boot that system and also do a speed test from there, I will share the problem screen images here.
Write speeds are OK but read speeds are low.
Try to disable anti virus and other security programs (don't connect to the internet).
Run Crystal disk Mark again and wait to the end.
Are you sure that the caddy uses a SATA3 interface?
What are the specs and the laptop, interfacing what is typically a DVD caddy?
What laptop model?
The I/O speed is not necessarily SATA3 but could be SATA1.
The throughput bandwidth pending on the read/write speed of the drive is rather limited does it could be that the port is only a SATA1. (CD and DVD writing speed - Wikipedia)
run a test software like Crystal disc first with your CD/DVD in the caddy and then with your SSD in the caddy.
Let me ask you this:
Do you have an SSD that clearly identifies it is SATA3 in the caddy which you push into your laptop or do you have a mini SATA adapter enclosure that contains a choice storage device inside?
What are you read/write cache settings?
How much RAM do you have a new laptop? (Are you heavily swapping him?)
What are your bio settings? Any relevant settings such as disk I/O 32-bit?
What does your OS detect?
Have you checked the device manager?
Years ago I had this with an early 120 Mb SSD, a similar situation and it was driver related.
Ultimately you could try caching software such as Primocache from Romex software which can dramatically increase your performance.
Here are two crystal disc showing you the performance increase on a Samsung SSD 960 EDO NVMe.
The first one without the caching software:
This one here with the same SSD but with caching software set to 4 GB.
In my computer everything seems to open instantly.
However sequential reads such as data transfers are faster in the beginning but slow down closer to a native Max transfer rate as there's obviously no more cached information. But anything that is repetitive such as opening & closing apps or is well within the cache size becomes lightning fast. Of course the more RAM you have the the bigger the cache you can create. I have currently 32 GB system RAM, 4 GB allocated for read/write acceleration and currently with all things running over 20 GB committed.

unfortunately there is no mini sata adapter but there is a 120 gb ssd a few minutes ago i changed the location of these 2 the problem is only hdd the read and write values in ssd are at normal levelLet me ask you this:

If the computer is 4 gb ram system, there is almost no setting in 64 bit bios, unfortunately there is no setting related to the disk.
hello again, sorry i kept you waiting
When I could not find a solution about this problem, I swapped the places of hdd and ssd and I took care of the problem, but I saw a problem when these two were swapped. While the voltage drawn by ssd is 5v 1a, the voltage drawn by hdd is 5v 0.55a I guess the problem is not related to the voltage.
