For playback almost every drive should be ok.
May worth to consider to use SSD/USB stick because those drives have no moving parts.
For the best performance please update the firmware on your LP-16 then format the USB drive with LP-16 before you starting to use first time.
Yes I can confirm all Cymatic Audio device using USB 2.0 port.
I made a test, in my test case the Sandisk drive heat up to 50°C.
I talked with our HW engineer he can confirm even 70°C cannot be a problem for the USB port on any Cymatic Audio device
For playback purpose the writing speed does not make any difference.
If you want to use only for playback the writing speed have impact only the transferring time where you export the song from your PC to your USB drive.
The playback not that sensitive for the USB medium type so you can use any kind of USB2.0; USB3.0 drives.
Thank you for the quick answer!
I actually ment reading speed, and not writing speed as I wrote 😳
So It should work with reading speeds around 130 mbps? It’s really smart with the very small usb drives but their reading speed is only around 130 mbps so if that’s not enough the smart part goes off 😉
