QNAP TR-002 Setup
If you plug two drives into the enclosure and plug it in, you will see the drives immediately show up in the system.
Here is a similar shot with the two drives configured as RAID 1 so we only get one device.
We showed how one can use the switches or the QNAP External RAID Manager to connect this to a PC or Mac in the How to Setup RAID on QNAP USB RAID Enclosure.
The enclosure can also be plugged into QNAP NAS units with USB ports.
From there, QNAP will label the enclosure as external storage and then allow you to do things like backup files to it, add it to the available NAS storage pool, or just to browse files.
We tried this, and one can write files from the NAS to the USB enclosure and then connect the USB enclosure to a PC and read drives. We also tried the reverse and it worked.
QNAP TR-002 Performance
On the performance side, here is a single Seagate Exos X22 20TB drive in the enclosure using ATTO Disk Benchmark.
We also tried accessing two drives using two instances of ATTO being launched simultaneously. One can easily see the impact on performance here.
Surprisingly good, however, was the RAID 1 performance. Here is what that looked like using the RAID 1 of the enclosure:
Overall, there were pretty decent results. Next, let us get to the power consumption.
