I used the docker-vaapi set-up on the same web page and I got HW encoding to work but not HW decoding so CPU usage was still insanely high.
I was wondering if vaapi was the best solution for Helios64 or OpenMAX is better like with the RPi?
I'd be weary of using dd
to benchmark drive, as explained here. My understanding is that while it was probably fine a tool to benchmark in the past, modern drives are built in such a way that cache etc. will skew the results.
FIO might be a better option, which is what the Linux folks use for IO tests apparently.
a 3.5 to 2.5" adapter on amazon costs less than 8$. (thats the 1st one iI found, not the cheapest). Even buying 5 of them hardy seems worth the effort you would spend making them yourself. https://www.amazon.com/ORICO-Adapter-Mounting-Bracket-Interface/dp/B01LZWX6PD/ref=sr_1_3?dchild=1&keywords=3.5"+2.5"+sata+adapter&qid=1610148495&sr=8-3
You should probably email them directly. I don't see why they wouldn't share that if you've already bought the Helios.
Also, something like this should work.

Just thinking. I have about 10 old disks and have no use for them right now. :-)

This is indeed very interesting device! Are there similar ones available? Does it really convert 2x 2.5" into 1x 3.5"? (Does it fit into normal 3,5" cage?)
Why are you looking to get extra SATA ports in the helios64, for what use? What do you think two sata disks for a single sata port You can go from 5 to 10 discs (9.5mm) internally. for example https://www.amazon.com/Mediasonic-Raid-Drive-Mobile-Backplane/dp/B07VL15GDG It would be best to increase the size of your disks before having to increase the number of your 2.5 bay or Nas helios64 3.5 Bay.
