XTx43/XDx33 players support the ATAPI logical interface for SSD, while the XTx44/XDx34 players support the NVMe interface. See here for more details.
Real Time Clock
All Series 3 and 4 players have a real time clock (RTC), except for the LS424. If you power cycle a player that does not have an RTC (and is not connect to the Internet), day-parted presentations will not play at scheduled times.
