Test System And Power Consumption
We used the default settings of the NAS device for our testing, meaning that we didn't use the jumbo frames setting. Each of the RAID arrays used the firmware-recommended sxt4 file system. For our tests, we used the firmware version 3.3.4 Build 1019T. Instead of the Samsung 320 GB HD321KJ hard drive with 16 MB cache found in past NAS tests, we transitioned over to the HD103SJ model with a capacity of 1000 GB and 32 MB cache.

Intel NAS Performance Toolkit
We tested the NAS device with the Intel NAS Performance Toolkit.
As both the housing and the fan of the TS-559 Pro+ are identical to those of the TS-550 Pro, we don't have anything new to report about noise levels. The 120 mm fan runs quietly and unobtrusively. It would be inaccurate to describe its operation as completely silent, but the gentle hum of the fan in normal operating mode is hardly noticeable, and would be drowned out by many PCs on the market.
Unfortunately, the vibrations of the hard drive in both the TS-559 Pro and the TS-559 Pro+ make an annoying rumble. A gentle pressure on the HDD bays is required to quiet the noise.
