Equipped with only a single hard drive, our test system proved to be little challenge for the DS380. The CPU and PCH chips were fairly comfortable on load, even with the fans set to just 5V. The power supply fan didn't even spin up throughout testing, not contributing at all to the modest overall noise level of 21~22 dBA@1m. Hard drive vibration was a complete non issue in this configuration, as we could feel only very faint tremors at the top of the chassis. The only thing that stood out was the hard drive temperature — 37°C might be considered a bit high for a lone drive with direct cooling. Increasing the fan voltage to 7V resulted in moderate reductions in CPU and PCH temperature, and increased the SPL to 24 dBA@1m.

TEST RESULTS: Four Hard Drives

The difference between the one drive and four drive configuration was instantly noticeable. The noise level jumped by 3 dB and the acoustic profile was dominated by a strong resonance that waxed and waned every ~1.7 seconds. Tonal peaks at 90 and 120 Hz corresponding to the drives' 5400 and 7200 RPM rotational speeds, pulsed up and down.

The drive cage itself is well-constructed but the way it links up with the rest of the chassis does nothing to mitigate the side-to-side reverberations generated by mechanical hard disks. They are easily passed on to the rest of the case creating this annoying throbbing.

The addition of three drives also made it more difficult to keep the system cool. On load, with the fans at 5V, the CPU and PCH heated up by an additional 3°C and the original hard drive warmed up by twice that. The rest of the drives were only lukewarm and surprisingly, increasing the fan speed to nothing to help cool them down. The extra airflow helped the other components but the drives were essentially unaffected.

As the intake fans are located on the left side, the system was a touch noisier when measured from that side (as we typically we do). When we positioned the mic on the closed-off right side of the enclosure, the noise measured was 1 dB lower across the board.

Compared to other mini-ITX cases housing our four drive server configuration in an idle state, the DS380 was a bit noisier (when measured from the left) and exhibited higher drive temperatures than the rest of the field.
