Cartridges or optical discs?

As do all flash based technology since they have the lower access latencies ... 

@Bold You can say that again since Nintendo hardly gives a damn about how fast their cartridges are if their willing to use monstrosity such as this ... (1-bit bus width, 45 MHz clock all for a whopping 5.6 MB/s!) 

My internet is faster at downloading than their 3DS cartridge read speads LOL ... (I wouldn't rule out Switch carts being possibly slower)

Well. The Switch's  cart transfer rate seems to be pretty competitive to MicroSD as per Digital Foundry's testing.

So we can summise that it is something like 80-90MB/s. Nothing ground breaking, but not entirely useless either.

How do you get to that conclusion. The article clearly states it maxes at UHS-1 speeds. That UHS-1 card they used has upto 80 MB/s read speed. And the game from cartridge loads slower than from an UHS-1 card. It's not useless but below 80 MB/s for sure. Too bad they didn't test slower cards to see how they hold up.

Anyway it's not the goroundbreaking difference with discs that people seem to assume when switching to cartridges. Lego city undercover still takes 51 seconds to load on Switch, compared to 1:04 on WiiU, yet much slower than on ps4 wich loads in about 30 seconds.
