@paul Supposedly it's popular and sells well. Plus, I've never regretted anything I've bought from Sonnet.
Of course it has some bandwidth trade-offs at 8x, but considering that it eats only one slot but provides so many things I really couldn't complain; I already have full-speed NVME cards eating up slots for the big stuff.
@evilpeacock just surprised I never hear of it until very recently.
