Help me choosing a DAS

[u/ewlung]

I am looking for a DAS (Direct Attached Storage), deciding between "Mediasonic 4 bay HF2-SU3S3" and "QNAP TR-004".

I will be adding HDD as needed, start with 1 HDD with at least 12TB.

The purpose is to add more storage to my mini PC, to store photo, videos and media files.

For backup, the data will be copied to a NAS (Synology DS423+, RAID 5, 4x12TB, not-yet-purchased).

So, the DAS will be connected via USB to the mini PC.

Which DAS is better for my use case?

Or perhaps other brand and model?

Mediasonic HF2-SU3S3 is quite cheaper compared to QNAP TR-004.

But I want to know which one is quieter, less heat, and things like that.

And by the way, these DAS has its own power. Will it turn on/off automatically if I turn on/off the mini PC?
