Notes
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.
