How to use an external hard drive on an iPad (mini)
What you need is the following:
Jailbroken iPad with iFile (app from Cydia)
USB adapter for your iPad; either the Camera Connection Kit for 30 pin devices, or the Lightning to USB Camera Adapter for Lightning connector devices
Portable hard drive formatted to FAT32 or another iPad-compatible format. I know for a fact that exFAT and NTFS won’t work.
External power system. This can be a hard drive that has its own power source, a powered USB hub, or an external battery pack like in the video
The video shows how you set everything up, though it will obviously vary a bit depending on the external power system you use. The setup in the video is completely independent of an AC outlet, and while I haven’t tested to see how long the battery pack can power the hard drive, I’m guessing at least 5 hours- though obviously you can buy a higher capacity battery pack. Because the drive is externally powered, that also means it won’t drain your iPad battery by powering it.
I think a flash drive setup would still be the better choice for a lot of people, but don’t underestimate the need for access to a terabyte of data on an iPad. Because this is also a two-way system, meaning you can transfer files to the device, it would for instance be possible for a photographer to back up images to a hard drive this way.
The cost of a lower capacity iPad plus the necessary equipment to add a terabyte of external storage is also much less than the premium for the 128GB model. An iPad 4 16GB WiFi is $499, and a 128GB version is $799. That’s a $300 difference that could be used like this:
Lightning to USB Camera Adapter: $30 https://amzn.to/3k9tdG7
15,600mAh USB battery pack (should be enough to keep the drive running as long as the iPad does): $35 https://amzn.to/2FsHMWs
2TB external hard drive: $56 https://amzn.to/3kdyaxV
Dual input USB extension cable: $1.99 https://amzn.to/3bRMCs9
Total: $123
(Disclaimer: I haven’t tried this specific combination of components, but it is essentially the same as what’s in the video, so it should work)
In this imagined scenario, $30 more than the price to go from a 16GB to a 128GB iPad gives you a whopping 2TB (~2000GB) of storage. Moreover, you get various accessories you could use for other things, like the USB adapter working for keyboards, the hard drive working on computers, and the battery pack being able to charge your devices as well. This accessory bundle would also work on future iPads (assuming they’re jailbroken), so you wouldn’t be paying the premium yearly.
Through the use of symbolic links you can even integrate the drive directly into your off-the-shelf App Store apps, creating a more seamless experience. Plug in your drive, open up your video player app, and browse gigabytes of data as if it was stored locally.
Like I said, this obviously isn’t for everyone, but it’s quite amazing that it actually works.
