Windows 10: Hard Disk Transfer Rate Goes Down After 1 to 2sec-Ex, Transfer rate going 70 m/b after 2-3...

Sorry for my language ı am not native,Hi, I have a 1TB Internal Hard Drive of Toshiba brand it have 5400rpm in past it transfer rate used to go 60 to 80 m/b continuously, but now it start from 60 to 80 m/b for only one second and degrade to 10 to 30 m/b. When I got this problem I scanned my hard drive it didn't have any bad sector. Even I booted my pc with bootable pendrive and checked it had same problem. I have also optimized my drive, scanned virus, booted in legacy and now at uefi. But When I check my drive performance in crystal disk it show me more than 70 m/b and less than 110 m/b.Is

How to increase disk transfer rate in Windows 10

Hello,

Thank you for contacting Microsoft Community.

Are you concerned about disk transfer rates?

It depend on your hard disk capability. The disk transfer rates varies depending on the action that is performed. Say for example, copying the data, running software, playing a game, running apps and some other. Moreover it also depends on the kind of the
motherboard and the type of SATA cable. Suggest you to perform disk defragmentation and see if it makes any difference in performance.

Defragment your hard disk:

• 
  Open Disk Defragmenter
  by clicking the Start button. In the search box, type Disk Defragmenter, and then, in the list of results, click
  Disk Defragmenter.
  
• 
  Under Current status, select the disk you want to defragment.
  
• 
  To determine if the disk needs to be defragmented or not, click
  Analyze disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  
  Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the
  Last Run column. If the number is above 10%, you should defragment the disk.
  
• 
  Click Defragment disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  

Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation
process.

Need explanation on odd figures from Copy/Transfer rates

---------------
--Update--
---------------

So basically the issue (You can read in details bellow) was that on copying files one gets three different readings , Explorer report a figure between 35 ~ 70 MB/s , Task Manager Disk % Transfer Rate reports double the number & yet Disk % Utilization never exceeds 50~60% .

Thanks to @dalchina & @Samuria I was able to experiment with the issue a little more and here are my findings :

1 - Apparently on file Copy windows deal with Explorer as yet another program running with Normal priority assigning to it a Quota of Disk % Utilization (a Cap) where Explorer as a program do the Reading then hands it in a Queue like action to the System Process to do the Writing , so Explorer just report its part (the Reading speed in MB/s) and yet Disk % Transfer rate combines it along with the Writing done by the System as well :




2 - The reason of priority and capping was revealed to me as on conducting the same experiment with Robocopy (A fast folder copy command line tool suggested by Samuria) , when the system reached its Disk % Utilization peek (95~100%) the system starts becoming slightly unresponsive .

3 - Now on the other hand Robocopy command despite not running in any higher priority somehow trigger the System to assist it in Reading so the Cap limiting is off (i.e the System Read along with it at the exact capped speed) to render a full Disk % Utilization :




4 - There are few side effects to Robocopy other than System responsiveness and those are :
a - The documentation is Jerky
b - You can't monitor progress or have an estimate on when it's done
c - It uses an odd method of committing all files in last step
(i.e you wont be seeing a single file output until it is done copying/moving all)
d - It is designed for directory copy , no file copy support

5 - Microsoft made a GUI for Robocopy as it is essentially a command line tool which is difficult to find so I have included it in post attachments yet however it only ease up using it but wouldn't solve the no progress monitor or time estimate or pause or cancel problem etc .

Cheers

Ok so basically I am trying to figure why would I get 3 different readings from windows from a file Copy/Move operation , first things first this is an internal SSHD trying to copy files to another internal SSHD both running on a Sata 3 interface .

Now the remark is I get a fluctuating rate between 70 ~ 35 MB/s reported on Copy/Transfer Dialogue and then exactly double the figure on Task Manager "Disk % Transfer Rate" and Yet less than 50% Cap to "Disk % Utilization" .





Now Maybe but not really sure I can assume that the "Disk % Transfer Rate" doubles figures to portray cumulative disk utilization of both disks . Now why is it still capped under 50% if the Sata interface can take it ? Defragmantation ? Can defragmentation cause a 50% cap ?

Which lead me to try it but this time to a USB 3 external HDD and here are the results :





Again the numbers are doubled in "Disk % Transfer Rate" and while the transfer rate is higher the "Disk % Utilization" is lower , so can anyone confirm why these numbers are all messed up like that ?

 

Slow internal hard drive transfer rates

Hi,

Please be informed that data transfer rates from hard drive to a computer or to other hard drive depends on several factors like size for data that being transferred; other tasks running in the background; RAM etc. You may install all pending Windows updates.
Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

Also follow the steps to run System Maintenance troubleshooter
on the computer:

• Type “Control Panel” on the search box.
• Click on Troubleshooting.
• Click on View all option on the left side of the Windows.
• Click on System Maintenance option.
• Click on Next and follow the onscreen instructions to troubleshoot the issue.

Do let us know the performance of the computer. Thank you.
