its windows 10

nothing else is open that could be taxing the pc

 

its a Seagate ironwolf thats inside the machine bought within the last 6 months. i recently bought a 16TB Western digital

 

the speed goes up and down but it usually says its gonna take a day to copy 300 gigs from internal to external.

How long is it taking?

 

I suggest you read this article (even though several years old, what it says still holds):  https://www.pcworld.com/article/2360306/usb-3-0-speed-real-and-imagined.html

 

When you combine the fact that copy actions typically get low priority if the OS has anything else to do, you're dealing with a platter drive, and you're copying 300GB of data that means it's going to take a while.  I'd be shocked if you could get this done in under 30 minutes, even if it's all you're doing, and it will probably take significantly longer than that.

 

The time estimates shown for the copy command for this much data should never be trusted and virtually never take as long as the estimate.  The larger the amount of data the shakier the estimate.  The actual transfer speed during a long copy such as this will zig-zag all over the place depending on what the hard drives are doing and what the OS needs to be doing besides the copy, which is always quite a bit.

 

If you're actually trying to copy 3 TB this will take a very long time, hours and hours at least.

It should only take about 5 hours to copy 1 terabyte.

A very important proviso from that page, critical, I'd say:  "The speeds are optimistic because the actual inferface will be slowed down by overhead (ex: requests for the information, syncs, ...), more than one transfer at a time, and the interface not performing at the standard speed."

 

Their figures are definitely on the "optimistic" side, though still useful in terms of having some frame of reference.

I agree Brian, that is why when I copy a large file I let it copy over night while I am sleeping. That way there are no concerns about how long it takes.
