Performance Rating

The following graph shows the NAS server's total performance rating, comparing it to other units. The comparison is pretty straightforward as the tested unit is shown as 100% and every other unit is relative to it. Please note that I only measure the raw performance in the graph below, not each unit's functionality and available feature set.



It is a big surprise to see the mini DS620slim taking the lead from the DS920+, but my sample didn't perform as expected in the multi-client tests, contrary to the DS620slim that fared pretty well.

Performance per Dollar

Most of you will find the following graph the most interesting as it shows how much the performance of the NAS will set you back. I looked the current USD price of each NAS up on Newegg and used it and all relative performance numbers to calculate the performance-per-dollar index. I search for the unit at other popular online shops (e.g., Amazon) if Newegg doesn't have the NAS in stock, and if the unit is not sold in the U.S., I search popular EU shops (e.g., Caseking), converting the price to US dollars.



The high price doesn't leave much room for a better score in this chart.
