SD Card and RiscOS

that may explain poor performance when copying or writing using OS_GBPB rather than load/save.

I’ve always found that using OS_GBPB to load/save the whole file in one call identical to using load/save.

In one call, Yes, quite likely.

Hi all

I have read that the Pi-Desktop add-on board connects to the Raspberry Pi via USB2.0. Does this mean that using a PiDesktop with internal msata disk or a regular Raspberry Pi case with external SSD connected to USB will lead to the same performance?

Thank you for your help.

Regards

In general terms, yes. Both are using the same USB2 bus so will be restricted to USB2 speeds.

There may be some difference between the USB-to-SATA boards themselves (RISCOSbits claim that their board outperforms the Pi Desktop board) but both are nevertheless hampered by using USB2.

I use a pi desktop with Pi3 with as my boot drive msata no need for an sdcard performance is slightly better than a class 10 SDcard but more reliable.
