Windows 10: Windows thinks it's using all my disk read/write speed

I'm having a problem with my PC, and I think that it is a software problem with Windows 10. The problem is that, in task manager, my disk usage is always 100% (or rarely 99%), no matter if I'm using 1 MB/s or 80 MB/s total.

I think this is having a bad effect on my system because my computer is running abnormally slowly and certain programs seem to have their disk usage surge and then recede, which I think means that they are trying to minimize their disk usage because they think that I'm using too much. This is a problem because when I'm trying, for instance, to do a Steam download, steam is keeping itself to a few MB/s of disc write, even though my internet and disk itself could support much more. My entire system also seems to be running slowly, which might be caused by this because disk seems to be the only maxed-out value in Task Manager.

Sorry if I rambled a bit, I'm very tired right now

Slow HDD read and write speeds

Hi,

Thank you for writing to Microsoft Community Forums.

We will require a few more information from you to help you further with the issue. Please reply with the following details:

• In which device are you facing this issue?
  
• Are you using an external HDD or internal HDD?
  
• Are you getting the read and write speed issue on any particular application?
  

However, you can Disk Defragment on your computer to optimize the drive. To run Disk Defragment please follow the steps from the article

Defragment your Windows 10 PC.

Alternatively, you can check for the read and write speed of the HDD in task manager. Please follow the steps mentioned below to check the read and write speed of the hard drive:

1. Press Ctrl + Shift + Esc key together on the keyboard.
   
2. Click on Performance tab.
   
3. Click on Disk 0.
   
4. You will find the Read speed and
   Write speed at the bottom of the window.
   

Hope it helps.

Please reply with the status of the issue, we will be glad to help you further.

Low Read and Write disk speeds (Windows 10)

the boot speed is fine, used to be slow but i fixed that. The main issue is the disk speeds. because i notice on start up after boot the disk is 100% with very poor write and read speeds. Focus on the Hard disk please. "There
is a lot of system HD writing." is this fixable?

 

Harddisk queries, partition questions and read/write speeds

I've always struggled to grasp quite exactly what it is that determines read/write transfer directions on drives as well as the correlation between benchmarks on hard disks and real world usage.

The first question is whether or not the drive your sending a file to is being written to, or is reading the data that's coming in. Are they the same operation or treated differently? The speed being reported, is this the drive that's sending the file or the one receiving it?

For the benchmarks, most of them show peak burst but not sustainable throughput and similarly so do reviews. Yet when you actually move anything but a single compressed file, you get speeds that are half what testing programs or reviews would suggest.
Why is it that reviewers never seem to just transfer random files manually and treat that as 'real world?'

Lastly, as per below picture, this is how my drives settled after putting in a second SSD and installing Windows onto it.

Unnamed EFI partition: SSD Disk 0
C: - Windows installation permanent SSD Disk 0
F: - Old Windows installation/temporary storage SSD Disk 1
D: - Storage HDD Disk 2
E: - 'System Reserved' EFI partition with data on it SSD Disk 1

For the unnamed EFI partition, it's great that it's the first partition on the disk however it's empty? What's the point of it then?
Is E: necessary?
Why is the EFI partition from Disk 1 listed as "Active and primary?"

Conversely, when I load up the old SSD, there's no EFI partitions for either disk showing in Explorer.

I am feeling OCD a bit on this and would like to clean it up so that everything is as should be.
