As the iPad has limited power capabilities, dependent upon the Storage Device, an external power source is often required. For HDD or SSD, an external power source is almost certainly required.
If your iPad Pro has a Lightning port, you will need to use an Apple Lightning to USB3 Camera Adapter to connect USB devices to the iPad. This adapter has both a USB 3.0 Type-A connector and an additional Lightning port to supply power, from your iPad's Power Adapter, to both the iPad and connected device. The Power Adapter must be rated at 12W or more.

If you have one of the newest iPad Pro models, with a USB-C connector, you may need to utilise a USB-C hub, connecting both the iPad Pro and the storage device to ports on the hub. If choosing a USB-C hub, ensure that the hub supports USB PD (Power Delivery) - and that manufacturer explicitly lists compatibility with iPad.
The external storage device will obviously require an appropriate USB3 cable to connect to the USB port of the Lightning to USB3 Camera Adapter, or USB hub if used.
To be recognised by iPadOS, the attached USB storage device must be formatted to FAT, FAT32 or exFAT (i.e., FAT64) with a single data partition. APFS or HFS+ are also supported by iPad and Mac. NTFS and other proprietary formats are not supported by iPadOS.
