• Regarding data concerning tests with RAM expansion, all memory slots are installed with the maximum capacity of supported RAM.
• The testing standard was based on the maximum number of concurrent connections supported by this model. During the testing, 25% of the connections were used to transfer files concurrently. The transfer process guaranteed that the connections were not interrupted; the minimum transfer speed was not guaranteed.
