Well that is slow in terms of raw HDD transfer speeds (130MB/s for a 5400
rpm SATA hard drive would be more typical), what you are copying and how
you copy it will make a big difference.
Copying many small files, at the file system level, will be much slower
than fewer large files. Thousands of small "few kB" text and config files
etc you might not get more than a few hundred kB/sec up to the low MB/sec >average throughput. For intermediate size files (photos etc), then 10 to >50MB/sec might be expected. Large 100MB+ files should copy at close to raw >drive speed.

I had forgotten how slow spinning disks are, the Iron Wolves were advertised as being suitable for a NAS, which is where they started life, and are in an HP N54L now. The 45,000 45 KB texture files for Flight Simulator may make a difference as well!
I am struggling with the final piece of my "how to organise storage" puzzle. I have decided a NAS doesn't add anything as my NVidia TV Pro is happy to read files from normal file shares without resorting to DNLA so I don't need a streaming app.
SSDs are still relatively expensive, close to £1K to replace the Iron Wolves. In addition I know from recent experience that when they fail they fail, totally, absolutely and no warning :-(
The replacement for the first failed WD SSD is due here on Wednesday, the second one should be a week or so behind. Horrendous process, taken 2 months so far. Their instructions are incorrect (I think pre Brexit) and I had to kick their customer
I am running a second copy process from my main machine to a USB 3 DAS, started this morning around 11 o/c and has a couple of hours to go. Also an Iron Wolf spinner so may have to think about using the DAS instead of the N54L as it seems much quicker.
Keeps the brain active :-)

Another option is that some SSDs or NVMEs usually come with a copy of Ghost
Or you could download and burn to a DVD a Ultimate Boot CD ISO or Hirens
Boot CD ISO and that has a gazillion utlities some of which will be disk cloning software....
Delivered by the SH of Ventoy fame :-D
dirVolume in drive H is Ventoy
It's called "seek time".
Moving the disk drive heads around, during
file by file data transfer, is slow. The seek
time is the "rate limiting step". It might take
a millisecond, to move the data from one disk
to the other. It might take 15 milliseconds to
move the heads for the next file. suddenly the
transfer is 16 times slower than we would like.
SSDs still have access time, but it is a lot smaller
number. Still, if you use CrystalDiskMark, and you
evaluate the 4K block transfer performance, the
number shown in the rating for the device, is
*quite poor*. While you may have marveled at the
SSD doing "500MB/sec" or an NVMe doing "7000MB/sec",
you can use tools such as CrystalDiskMark, to see
what the rate limiting performance will be.
There is*no good answer* for small files. Small files suck.
If you insist on using file-by-file transfer, you're doomed
to be doing this arithmetic, figuring out the transfer
speed and moaning that it is so so slow.

Any solution that involves imaging/cloning seems to mean booting to the software rather than running it under Windows.
An exception I have is MiniTool Partition Wizard which I used to clone 1
x Iron Wolf Spinner with 2.5 TB on it to an identical drive which took
about 8 hours.
SmartSync Pro takes 32 minutes to work its way through the whole backup regime which involves 10 drives with different stuff on them.
The killer is the original copy to an empty drive, I only have to do
that if I change the structure of things so it's in my own hands.
