Data transfer
I carried out several tests, starting with a local transfer over a longer period of time with OpenSpeedTest. I was able to achieve the following result:
And this is what it looks like when a single 10GB test file is copied from the computer to the NVMe SSD:
I also noticed a similarly “hilly” transfer rate when transferring to the SSD RAID0:
One thing the two volumes have in common is the BTRFS format. So I converted the SSD RAID0 to EXT4 as a test and lo and behold:
I assume that these differences are due to the additional functions of BTRFS such as snapshots, redundancy and compression. However, the transfer is still fast regardless of the file system.
Power consumption
The consumption was measured from the socket, so it also includes an installed NVMe SSD. I have removed all others in order to get as close as possible to the value of the NAS alone. The actual power consumption ultimately depends primarily on the hard disks or SSDs used in your setup.

Sound level
I determine the sound level with a Voltcraft SL-200 measuring device at a distance of 40cm, which works in 125ms cycles in Lo mode, an external example table helps to break it down.
