Please help!! Extremely slow file transfer rates over ethernet crossover cable

[hagakure_s81]

Please help - no idea what's wrong here.
I want to transfer files from 1 pc to another, both running windows 10. But the transfer rates are super slow. Right now its going at 350kbps but sometimes drops to 0 for a while, then 20kbps etc.

I can see the 2 computers on the home network but PC2 won't let me access the HDD of PC1, saying I don't have permission, despite drive sharing on. PC1 can see and access HDD on PC2 though.

Shouldn't the crossover cable be capable of transfers rated in gbps?

If I go to task manager / performance on PC1 it says throughput of 100kbps then changed to 11mbps. But even 100mbs of data took like 30min to transfer.

PC2 says throughput is showing anything between 100kbps and 11mbps during a transfer. If no transfer it was saying 1gbps

PC1 is old system, with asus M4N68T-M motherboard, and says network adapter is Nvidia nForce networking controller.
It also shows a bunch of WAN miniport entries that weren't there before.
PC1 created the homegroup

PC2 is old system, with asus Z270-AR motherboard, and says network adapter is Intel (R) Ethernet connection (2) I219-V

I turned off firewall on both computers.

The concept of crossover cables is very old. First there is no such thing on 1g connections. It actually transmit and receives on all 4 pair of wires at the same time on both end simultaneously. Never understood the details of that magic but the ethernet chips just accomplish it.

In many cases if you use a actually cross over cable the port speed will drop to 100m...which gives you 11mbyte transfer rates. Even if the ports were 100m you should always use straight cable today because the all modern ethernet ports have the mdi/mdix feature to automatically make a straight cable into a cross cable.

The hard drive transfer speeds may also have an issue. Just remove the drive from the system, install it into a USB enclosure and copy that way. If it still copies slow there is an issue with the drive.

I do know that the hard drive is a reasonable old one now. WD20EARS-00MVWB0 Caviar Green if memory serves.
I came to try the ethernet link because my first attempt at transferrring files wouldn't work.
I tried to simple plug that drive into my new system and access it there, but could not get it to work.
All it showed up as in explorer was as drive named NTFS, and I was denied access no matter what.
In my old system it functions normally though.

I don't have a USB enclosure unfortunately. I do have a external 2.5" HDD I can use, but its damned labourious and with the old USB (1 I think) connectors on the old system its damned time consuming. However I can transfer to those at around 10-20mbps so I guess I'll just do it that way.

Just an update - yesterday trying with both the crossover cable, and same thing with a regular ethernet (cat.5) cable, no difference. I was getting transfer speed that would go to 350kbps then 0, then another burst, then 0 etc.
So I tried using a router lying around unused, and straight off I got up to 10mbps. Still not phenomenal, and doesn't beat the USB external HDD speed but at least it was possible to check/move a few things

This is the problem with researching yourself on google lol. I had seen a few people say crossover wasn't required but no followup, while 90% of places I looked said you MUST have crossover cable.
Anyway as I replied to the other person, using a regular cable on its own didn't make a difference until I put a router in between.
