Interesting video indeed but the sample size is too low in some instances and the comparison is only between 2 or 3 brands. So I would take the stats with a grain of salt.
Most interesting part (and one that was expected) is the RMA rate of Samsung SSD which came out at 0%. I knew Samsung SSDs were reliable but this much... Just wow. Again though the sample size is only 222 here. Also it says "other brands 6-28%" in the video, which brand had 28% RMA rate? That's insane. Surely it must be a trash tier brand with sample size in lower double digits right, thus skewed towards higher percentage. Otherwise I don't see how could the numbers be so high. I wish he had briefly given stats of those as well (or just shouldn't have mentioned it in first place).
Another interesting part (and one that most people wouldn't expect) is the RMA rate of Superflower PSUs at 0%. Again I should say the sample size is quite low but Superflower is one of the leading brand in PSU market (along with seasonic) and they are OEM for other major brands as well. Knowing this I knew this result was expected.
The channel seems underrated in my opinion.
P.S. someone tell him to fix his mic lol. Guy seems well educated in the field so don't know why he didn't put a noise suppression filter during or after the recording.
