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.

Sporadic extremly slow read speed on hard disk

For some time I have a sporadic issue with my hard disk, showing up in the form of extremely slow access time (~200 ms according to Windows) and read speed (~ 1 MB/sec). This holds even for sequential access, e.g. trying to copy a large file. However, write speed is absolutely normal (> 100 MB/sec) when copying from another disk. Rebooting often makes the issue go away until the next restart.

This is what it looks like in Windows when the issue occurs:




Sometimes I have the feeling that if I quickly access the drive after booting that the issue does not occur.

This is a secondary classical magnetic hard disk, Windows is install on an SSD, which does not have these issues at all.

What I already tried:

• Reinstalling Intel Storage drivers
  
• Using a different SATA Port on the mainboard
  
• Using a different hard disk
  

None of these helped - the other hard disk had the exact same issue. So I do not think it is a defect in the hard disk.

Some background info:

1. Windows 10
   
2. Mainboard is MSI Z170 Carbon
   
3. The issue occured with a
   Seagate Barracuda 2TB and with a Seagate Firecuda 2TB
   

 

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?
