So basically SK4 is using military grade memory(HS600),probably Silicon Go(industrial storage solutions) had leftover chips,which were produced for some medical or military equipment.
The industrial grade test is using much bigger block size,that is why results can be very different from CPDT benchmark,that uses 4mb block.
Currently SK4 that I have is a record holder,amoung all TV boxes I tested,industrial test result is 579MB/s write speed.
Here is a more complete hardware information:
Also in terms of hardware decoders it is overkill,all necessary stuff will work without any stutters and droped frames.Green is hardware decoder,blue circle is software decoder(mostly used on some audio stuff)
P. S. Bitrate 80mbits doesn’t mean device can’t play 100mbits videos,SK4 can handle videos with even higher bitrates,most of the heaviest Blu-ray movies that exist have around 60mbits of bitrate,so measuring bitrate above 80megabits is not necessary.
