A A percentage measure of component performance per price for typical real world use.
For each component class the UBM effective speed is based on thousands of user benchmarks. The aim is to quantify real world performance for typical consumer use. The value for money rating scales UBM effective speed by current market price to arrive at a percentage which is chosen to ensure that the best value mainstream component scores 100%. The specifics are component dependent and take into account factors such as capacity where larger drives tend to be cheaper per GB and therefore offer better value. The value rating tends to favor additional performance over reduced price because when considering a $100 component most consumers would rather pay an extra $15 for 10% more performance.
