Librem 6 Look Ahead Wishlist

I’m copying the same files onto microsd cards inserted into both my L14 and L5’s. The microsd cards are the same, the files I’m copying are the same, and you could sell me a bridge if I were to believe the USB versions are making up the transfer time difference. PS As I mentioned, this is just one example.

First: You didn’t say that you were testing with microsd cards.

However … that’s even more important. And while I’m not selling you a bridge, others here will understand that the sdcard on the L5 is on the USB2 bus. That’s right. USB2.0 speeds!!! For most sdcards (UHS I for read and II for read/writes) the USB 2.0 bus is the limiting factor.

Unless you are doing checksums or encrypting on the L5, CPU speeds won’t be the limiting for a copy IMO.

Why would you think CPU speeds would be the difference???

Aside: Perhaps you’ll buy a bridge from Amos Librem 5 Phone - SD Speed .

Edit: You could test the differences by buying a USB3.0 (not 3.1) USB-c external sdcard reader and seeing how that compares between the Librem 5 (USB3.0) and Librem 14 (USB3.1). Compare those read/writes with the internal sdcard slots for the L5 (USB2) and L14 (USB3.1).
