Why?

SSD cabling or signal issues can cause read errors. After several drive errors, the Windows® IDE/ATAPI port driver (ATAPI.SYS) will reduce the transfer speed in an attempt to eliminate the errors.

How to Check?

1. Right-click My Computer and select Properties.

2. In the System Properties window, select Hardware tab.

3. Click Device Manager.

4. In the Device Manager window, double-click IDE ATA/ATAPI Controller.

5. Right-click the ATA Channel 0 and select Advanced Settings.

How to Change?

If the observed setting is not UDMA 5, it may indicate a problem with the SSD cable. Confirm the SSD cable is installed and seated properly.
