MSE "Custom" Scan Took 6 hours

Is that normal? This is a graph of my hard drive:

Long scan times are to be expected if you're doing a full scan for the first time. It also depends on your computer specs and if you're multitasking which can hinder speed. It takes almost 2 hours for Windows Security to scan a 120GB Drive of mine. Kaspersky's free av scans usually takes 45min-1hr. Microsoft scans have always been slow for me.
