TESTING METHODOLOGY – TEST RESULTS

   Since some of the NAS servers/devices we have tested in the past are no longer in our possession (naturally) we will keep performing the exact same testing methodology we did in the past for as long as possible in order to provide accurate comparison results. So as always we will be using a single Seagate Constellation ES.2 3TB SATA III hard disk drive with the unit at hand (just like with all of the NAS servers) and perform several upload/download tests with a single 10.9GB file. Tests are repeated a total of 4 times after which we record the average numbers (from the 4 peak ones) into our charts. Finally the network device used is the same Netgear DGN3500 Gigabit ADSL2+ Modem/Router we always use when performing tests on NAS servers.

FILE TRANSFER TEST

A single 10.9GB file was uploaded and downloaded to and from all the NAS units in this test. Well not much we can say about the read/write performance of the N5550 since the fact that it managed to match the performance of the much more powerful TS-470 speaks for itself (we know that the TS-470 may have issues with the beta FW version so we will test it again in the future).

TEMPERATURES

At 34 degrees Celsius this is another similarity between the TS-470 and the N5550.

POWER CONSUMPTION

I don't really know why but the power consumption of the N5550 was slightly higher than that of the TS-470 at full load.

NOISE LEVELS

Same case with noise levels since the 92mm fan by ADDA went over the 47dBA mark.
