typical microsd speeds?

[Rogerss]

What speeds are you guys getting when transfer games to your microsd cards? I only see around 15-16 MBs

Depends on the card.

Depends on the card.

ok? What card for better speed, The advertised speeds are never right.

The transfer speed is only relevant when transferring from a computer to the SD card, U3 card get you around 75MB/s

32-40MB/s with Awoo over USB3 (Macbook Air).
Goldleaf around 20MB/s.

BestTM cards to buy are Samsung Evo Plus ( https://www.amazon.de/Samsung-microSD-Adapter-MB-MC512HA-EU/dp/B089S23BVG/ ) at a high capacity (capacity matters, because the 64GB cards they produce under that series half write speed). Best price/performance anyhow.

Google that series and write speed comparisons.

And make sure you are getting genuine ones.. (Dont buy from ebay or aliexpress in that instance.. )

Those are max speeds reached by CTCaer.
Usually bottleneck is on homebrew side.

For me when i copy a NSP over to microsd card i get 15MBs with the card in a reader connected by USB3.

It's a sandisk.
