The Intel 520 Series was Intel's first SSD to feature a Sandforce 2281 controller. This controller has powered countless SSDs over the last three years but is now dated and is known to be limited in the area of incompressible write speed. The 120GB Intel 520 scored peak and average sequential read/write speeds of 514/157 and 421/133. These read speeds are good but the peak write of 157 MB/s lags the group leaders average of 313 MB/s by nearly 100%. This relative inability to write lowers the 520's overall effective speed to 403 MB/s or 15% lower than the 459 MB/s achieved by the group leaders. At two years of age the Intel 520 can no longer compete with newer drives, there is far better value available amongst the group leaders[Feb '14 SSDrivePro]

Above average average bench

The Intel 520 Series 120GB averaged 36.6% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.

Strengths

Avg. 4K Random Read Speed 28.2MB/s
Avg. 4K Random Write Speed 75.6MB/s

Above average consistency

The range of scores (95th - 5th percentile) for the Intel 520 Series 120GB is 30.3%. This is a relatively narrow range which indicates that the Intel 520 Series 120GB performs reasonably consistently under varying real world conditions.

Weaknesses

Avg. Sequential Write Speed 144MB/s
Avg. Sequential Mixed IO Speed 211MB/s
