Sluggish file copy and move speeds

I've been meaning to ask about this for a very long time but keep forgetting. 

 

For as far back as I can remember, sustained copy and move actions start out very fast and then drop dramatically and often even stall. It doesn't matter which Windows version or hardware. For a while, I used Teracopy. I do this sort of thing many times a week and I was wondering if there is a solution, or if I should go back to Teracopy?

 

Thanks!

I think that might warrant running chkdsk /r on the partitions/drives...and/or defrag.  I routinely run chkdsk /r but hardly ever bother with defrag...all SSDs, no mechanical HDs.

Thanks but the windows version and hardware have no impact. It has happened on every windows computer I've had no matter the storage type, amount of memory, CPU, etc.

You are not alone in this. I have had this happen over the years since 1999 and also in a corporate and enterprise environment across multiple media formats.

I do not get this on Linux under the same hardware.

Probably not your issue but see if temporarily disabling file indexing helps.  Method 4.

Ok. Jonuk

I would think that a disk cache might be the cause.  When it's full, it's the pure disk speed.

And what is the solution to that on HDD and M.2 SDD?

I tried but it didn't seem to help. I have a Team Group Cardea 4TB that's about 45% empty.

If it's a cache issue, the technology served its purpose.  There's nothing you can do about it, but to live with it.  You will only notice user interface performance gain for common file sizes, not exceptionally  huge files.

Provide the model numbers of the drives.

Again this has happened on multiple HDDs and SSDs over the past 2-3 decades. It is not new, nor is it related to the presence of DRAM, nor is it about interface.

Well if you cop an attitude like that then you'll not get answers.

But caches have steadily increased in size from 2negs to several hundred gigs. Also spindle speeds in hdds matter as does the dram chip type and quality of speed.

I've had the exact opposite experience with transfers between hard-drives rated at 7200 rpm and ata100 to ata133 stanards to sata 1,2,3 specs, to ssd/nvme/m.2 ssd.

Only time I get slow is via optical transfer.

No clue what attitude you think I'm copping. I am simply reiterating what I said before because it's been an ongoing issue with multiple computers, storage devices, Windows versions and in 2 different countries on opposite sides of the world. Terracopy doesn't have that problem. I guess I'll just have to start using it again.

Was the model info you requested insufficient?

Never heard of that brand all my drives have been seagates/maxtor and Samsung it's been slow but not insanely slow gigs transfered in mere minutes on my Samsung ssds and 5 to 10gigs took 30 minutes to 40 minutes on my spinners of 7200rpm.

The attitude is like I don't know what I'm talking about and you are far superior than me.
