What are the differences between using a USB-C and Lightning adapter for an external SSD on an iPad Pro

Speed and Versatility

- USB-C: This port offers faster data transfer speeds compared to Lightning. USB-C supports higher bandwidth, which is beneficial for transferring large files quickly. It also allows for more versatile connections, such as video output to external monitors or TVs, making it ideal for tasks like video editing or presentations[1][4].
- Lightning: Lightning ports are generally slower, with a maximum bandwidth similar to USB 2.0, which is about 60 MB/s. This can lead to slower file transfers and may not support video output directly without additional adapters[4].

Compatibility and Future-Proofing

- USB-C: As a universal standard, USB-C is widely supported across various devices, including laptops, smartphones, and tablets from multiple brands. This makes it easier to use the same cables and accessories with different devices. Additionally, USB-C is future-proof, as it is likely to remain the standard for many years[1][4].
- Lightning: Lightning is a proprietary connector that is being phased out in favor of USB-C, especially due to EU regulations. While adapters can be used to connect Lightning devices to USB-C ports, they may not be as reliable or efficient[1][4].

Power Output and Reliability

- USB-C: iPads with USB-C ports are designed to handle more power output, making them suitable for connecting multiple peripherals simultaneously without needing an external power source. This is particularly useful for tasks requiring multiple accessories like MIDI controllers or external drives[4].
- Lightning: Lightning ports have limited power output, which can lead to issues when connecting power-hungry accessories. Users may encounter errors stating that an accessory requires too much power, even when a power cable is connected[4].

External Storage Connection

- USB-C: Connecting an external SSD via USB-C is straightforward, as most modern SSDs come with USB-C connectors. This allows for direct connection without additional adapters[5].
- Lightning: For iPads with Lightning ports, a Lightning to USB Camera Adapter is required to connect an external SSD. This setup can be less reliable and more expensive than using USB-C directly[5].

In summary, using a USB-C adapter for an external SSD on an iPad Pro offers faster speeds, better compatibility, and more versatility compared to using a Lightning adapter. USB-C is the preferred choice for future-proofing and handling multiple peripherals simultaneously.
