It slows the computer down
WDFME is for USB 3.0 and compatible with 2.0; older computers have only USB 1.0
It cause locks and resource hogging due to software faults. It is western digitals backup utility.

Causes high usage of CPU and memory hence the fan noise on my Sony Vaio S Series was too high, when I ended the process the fan noise disappeared, highly recommended action. turn it on again when you need to do your backup using WD SmartWare
It consumes more process power than it's worth
max CPU usage - deleted
The WD Forums have many complaints about massive CPU usage by WDFME. I found this app. while searching for solutions.

Best practices for resolving WDFME issues

A clean and tidy computer is the key requirement for avoiding problems with WDFME. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WDFME.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
