What operating system are you working with? If it is a Windows based system, Microsoft is hosting an article that touches on the subject. The blog is about why moving large numbers of files around by way of copy and paste is a bad practice, but touches on the subject you asked about.
Moving and copying should end up doing mostly the same behavior, in terms of necessary processes. I'm not 100% certain on that, however. In any case, 10 mins does seem high. I would still recommend robocopy, that way you can see if a multithreaded operation helps out at all. You'll want to use the /mov option to avoid duplicating your files.
As far as measuring disk IO goes, there isn't a Dell utility, to my knowledge, but there is a 3rd party tool called "Iometer" that would provide the information you're looking for.

Hello,
What operating system are you working with? If it is a Windows based system, Microsoft is hosting an article that touches on the subject. The blog is about why moving large numbers of files around by way of copy and paste is a bad practice, but touches on the subject you asked about.
https://blogs.technet.microsoft.com/josebda/2014/08/18/using-file-copy-to-measure-storage-performance-why-its-not-a-good-idea-and-what-you-should-do-instead/
Basically, it creates a lot of serialized requests that are handled in order, as opposed to a parallel operation, like with robocopy.

Hi Dylan,
Thanks for your reply,
The OS of the server is server 2019 and OS and hardware firmware all up to date.
I forgot to mention that we move the files and not copying them.
When we copy 3 GB of small files from one drive to other drive it will take almost 10 min!!
Does Dell has an utility that we can use to check the drives IO?
We move the same 3GB files on one of our R730 and it went faster. this server has HDD SAS drives in RAID configuration.
move on this server was done from RAID 10 virtaul disks to RAID 0 disk.
Thanks
