Hi, you're WDC WD5000AAKS was first on the marked begin 2007, so it is kind of a old model. However, on SATA/300 it should reach 95 kb/s, with optimal drivers. In the Bios is you're SATA operation on ATA or AHCI? Don't change it yet, otherwise you're Win10 will not boot, but AHCI is the best option.
How to change:
to switch operation from either IDE (or RAID) to AHCI within Windows 10 without having to reinstall. Here’s how.
- Right-click the Windows Start Menu. Choose Command Prompt (Admin).
- If you don’t see Command Prompt listed, it’s because you have already been updated to a later version of Windows. If so, use this method instead to get to the Command Prompt:
- Click the Start Button and type cmd
- Right-click the result and select Run as administrator
- If you don’t see Command Prompt listed, it’s because you have already been updated to a later version of Windows. If so, use this method instead to get to the Command Prompt:
- Type this command and press ENTER: bcdedit /set {current} safeboot minimal
- If this command does not work for you, try bcdedit /set safeboot minimal
- Restart the computer and enter BIOS Setup (the key to press varies between systems).
- Change the SATA Operation mode to AHCI from either IDE or RAID (again, the language varies).
- Save changes and exit Setup and Windows will automatically boot to Safe Mode.
- Right-click the Windows Start Menu once more. Choose Command Prompt (Admin).
- Type this command and press ENTER: bcdedit /deletevalue {current} safeboot
- If you had to try the alternate command above, you will likely need to do so here also: bcdedit /deletevalue safeboot
- Reboot once more and Windows will automatically start with AHCI drivers enabled.
- Right-click the Windows Start Menu. Choose Command Prompt (Admin).

As for your specific HD, even at 7200RPM S. A. is correct about changing the drive parms from ATA to AHCI, but depending on your workload, you will still more than likely see fluctuating speed results. However, There is a easier way to switch to AHCI mode and that's to install the Intel's chipset drivers.

Test with AS SSD https://www.alex-is.de/PHP/fusion/downloads.php?download_id=9
My scores are here. If you're controller is on AHCI it will say so (where the 2 "OK's" are). If you hold you're mouse on it, it will say which drivers are loaded. More you cannot do for optimal speed of HDD, or get an SSD.
