Earlier, I posted a review of a new model of the RAVPower FileHub, the WD007 – https://forums.macrumors.com/threads/new-ravpower-filehub-model-review.2128117/ I noted a number of issues in that review and since that review, RAVPower has released an update, the WD009: https://www.amazon.com/dp/B07M6P618P I have received a copy of this device and can report on it. This update has addressed a number of issues I identified, the most significant being the overheating problem – this was so severe that I discontinued using the WD007 as I was concerned about damaging inserted SD cards. This issue has been resolved with the WD009. Other improvements have been made, including increasing the size of the internal battery and reverting back to the micro USB power interface in lieu of USB-C. Data access and copying speed is comparable to the WD007. Overall performance of the iPad-hosted app also seems improved, being “snappier” (the app did not change but performance with the new device seems quicker). General functionality remains the same as with earlier models. I just used the older WD03 model on a week-long photo trip and used it to copy many GB’s of photos and videos from my camera’s SD card to a USB-based Samsung external SSD. I also used it for streaming movies from a 4TB HDD to my iPad. It worked great and I will now be using the WD009 in a similar fashion. I've been using a FileHub with my iPads for 3.5 years now and they are great accessories for external file management.
