The Philips «Ultra Portable (1000 GB)» external SSD can be connected to a Raspberry Pi 5, but it requires using one of the available USB ports, not the USB-C port reserved for power. The Raspberry Pi 5 has two USB 3.0 ports that can support the SSD's USB 3.0 interface, allowing for faster data transfer speeds compared to using the USB-C port for data, which is not possible if it's used for power.

To free up the USB-C port for data, you would need to power the Raspberry Pi 5 through another means, such as the GPIO pins or a Power over Ethernet (PoE) setup, if available. However, using the USB 3.0 ports is the most straightforward method for connecting the SSD.
