The NVS-30 will support writing to USB3 devices at USB2
speeds. Also note, there is a very high variability in the
performance capabilities of “thumb” drives (even USB3
versions). Many are optimized for “read” operations while the
NVS-30 requires sustained “write” capabilities. For best
results, NVS-30 recommends using powered USB drives. If
small portable media is required, SD cards may be more
suitable.
1 x SD card Slot
