Are you, by chance, indexing this drive after the transfer of data?
Or something notoriously touches the disk all the time.
I have already asked him about indexing 
At the first glance, it looks like if something touches the disk all the time⌠

Well there is BITS
Time to fire up perfmon and see whatâs hitting the disk then.
@jimgordon Windows doesnât allow me to format it in anything other than NTFS or FAT32 on unallocated space of the same drive.
@TimHolus I donât see anything physically touching the drive, if thatâs what you mean.
@Adubs I donât know how to operate the perfmon so Iâll look into it later.
I will be providing more screenshots below.
New 10GB partition in NTFS since exFAT was absent from the options.
This is the drive properties in windows explorer itself.
I donât quite honestly remember anything about the indexing.
Those SSD speeds look perfectly fine to me if the ssd is a sata one.
So yeah maybe try to defrag the hdd again.

@MisteryAngel The SSD scores were there to show that the problem is only within that one drive. I did defrag couple of times and it doesnât really help any further.
Replying to everyone else now.
This is during ATTO 48MB test, I could also record the program going through the process while recordingâs output is going to other drive, if you want to see it in action.
And this is the ATTO results. on main partition of the disk.
The speeds are kind of inconsistent, though maybe itâs writing on that zeroed out part again but I wouldnât know.
Hey there @MrSmiley did you get an solution to this? I have a similar issue but even worse results with one of my 2 st2000dm008 drives.
Iâve only joined this forum to see if there is an answer.

Basically from what I understood it has something to do how drives like that function, since itâs SMR, rather than PMR drive. I might be wrong but thatâs what I gathered.
TL;DR, it functions as it should.
