Just bought Jetrdive Lite 330 512GB for MBP M1, to store downloaded junk that I ocassionaly still need to go through (I am lazy in cleaning up such stuff), it was pretty cheap (around 80$). But with Blackmagic test the write speed on mine is 35MB/s (read is 85MB/s) straight out of the box... Any ideas why such difference to the one in test? It is formatted as exFAT...
Check out some of the reviews on Amazon. Some reported the same, and it seems it might depends on the implementation of the USB 3 SD card reader in the laptop (MacBook in this case). Is your MBP a 14/16" or a 13"?

Thanks, I will look at those... It's the 16" M1 MBP, which should be "compatible" according to Transcend

EDIT: I have erased the drive and chose MacOS Ext filesystem instead of ExFAT and now I get 75MB/s as advertised :) I thought filesystem should not affect speeds, but apparently does on this SD card...
