Wich raspberry version do u recomend?

Both responses are correct. Since a USB3.0 drive is backward compatible with USB2.0 interfaces, you have a choice of RPi3B+ and slower disk throughput or RPi4B and faster disk throughput.

There’s no particular advantage to the faster disk throughput during playback but it will speed up the transfer of files onto the disk from elsewhere.

Remember that power consumption and heat generation are higher in the RPi4B.

also, in my country 3B+ is out of stock, The 3B would be enough to a pleasent experience?
