Low Read and Write Disk Speeds (Windows 10)

Over the past year or so, I have a slow startup on my computer. At first, I just ignored it, but now I desperately want to find a way to fix it. I have noticed my hard drive has very low, read, and write speeds. I've got a worrisome dilemma here regarding my HDD. It's 2-3 years old and mainly used for storage with 300GB space left. Too often lately, I have hard drives that slow down to a crawl. Pulling the drive from the computer and testing it with HDTune shows the read speeds to be less than 5MB/s. Is there anyone who can help me?"

Why Your Hard Drive Gets Slow

HDDs and SSDs are commonly used in your daily life to store films, games and other files rather than with a flash drive or a DVD. However, sometimes a hard drive may become slow to read and write, and for no obvious reasons. To find out the reasons and solve the slow hard drive issue better, you should give you a head start on understanding what causes slow performance.

  1. 1. Torrents and P2P software
  2. 2. Insufficient power or USB ports
  3. 3. Not enough free hard drive space
  4. 4. Logic errors and bad sectors
  5. 5. Damaged disk
  6. 6. Hardware failure...

Now that you have known the reason why the hard drive takes a long time to read, you can follow the fixes to solve your problem and speed up your hard drive easily.

Solution 1. Turn Off or Uninstall Unwanted Programs on the Slow HDD

At the same time, you may be downloading several torrent files to your disk, watching a film from the same disk, and checking the same disk for viruses. Can you imagine the amount of hard work you have given to the disk? At this time, you should check your Task Manager and uninstall unwanted programs.

1. Check the Task Manager

Check for programs making frequent read/write requests to the disk in Task Manager. Make sure no unwanted programs are tying up your disk in the background.

Step 1. Type task manager in the Windows search bar and select "Task Manager." 

Step 2. In the Processes tab, look at the "Disk" process to see what is eating up your hard drive space.

2. Uninstall Unwanted Programs

If there are too many unwanted programs on your hard drive, you can uninstall them to speed up your hard drive.

Step 1. Click "Start > Control Panel".

Step 2. Select "Programs and Features". 

Step 3. Then, select the program to remove. With the program selected, click "Uninstall".

Follow the uninstall instructions that appear on the screen. Be sure to remove all of the components if prompted.

Solution 2. Check the Transferring Speed of the HDD

If Task Manager looks OK, check how long it takes to transfer a large file to the disk. 

Step 1. Copy files from the original hard drive.

Step 2. Paste these files to the target drive to see the transferring speed.

check the transferring speed

It should be close to the drive's advertised read speed (this may be affected by how the drive is connected i.e. USB 3.0 versus SATA).

Solution 3. Switch the SATA Cable Port to Fix HDD Slow to Read

Another effective way to fix a slow hard drive, especially for the hard drive that fails in a fast file transfer or read speed, is to disconnect the SATA data cable from the first SATA port on the motherboard (where it was always connected). Then connect that same cable into the last SATA port. Sometimes, it's a problem of a dusty or loose SATA cable that slows down your SATA HDD without warning.

Step 1. Disconnect the SATA cable from the first SATA port.

Step 2. Reconnect the SATA cable to the last SATA port.
