The first article is a paid promotion piece, which WP won't accept as an RS.

The second is a press release by Arrow's sponsoring company, which, obviously, WP won't accept as an RS.

I have no idea what "The Silicon Review" is; this is the first time I've ever seen it. To the extent it's not a pay-to-play trade publication, it might qualify as a notability-establishing source. The fact that the "Review" does not itself have a WP page might make it harder to claim it's reliable, since it suggests nobody else knows what it is, either.
