As the name tells you, this single device turns iPad Pro's USB-C port into six different ports, here's what you get:
3.5mm audio output. This lets you connect a pair of headphones with a traditional connector, I usually use AirPods to listen to audio from the iPad, but there are two circumstances where I find it useful to use traditional headphones. I do not have AirPods high enough to hear the background noise of an airplane. Traditional headphones are just a little louder. Secondly, although my AirPods are almost always in my pocket, I sometimes forget them and it is useful to use any any random headphone I find at home or in the office.  USB-A. This is the traditional USB size, and HyperDrive uses high-speed USB 3.1 Gen 1 that can transfer 5 GB / s speed. When iPadOS comes out later this year, you will be able to use this port for to access the files on a thumb drive or an external USB drive. You can also use this to connect to an external keyboard, and when iPadOS comes out, you'll be able to use this to connect to a mouse. You can also connect MIDI audio devices, a microphone, cameras that support USB, a USB to Ethernet adapter, etc.
SD memory card. Use this port to connect a memory card. I use it to transfer photos I take using my DSLR camera to iPad Pro. Thanks to the beautiful screen of the iPad Pro, this is a great way to look at photos right after I take them, delete the bad ones and make changes to the ones I need edits. It's fast and works well.
Micro SD Memory Card. I currently have no devices that use Micro SD, but I like to know that if I come across such a card, I'm ready for it.
USB C. This is useful for two reasons. First, you can use the same cord you normally use to charge the iPad, even while the hub is attached. This means you can use this hub and also charge your iPad at the same time. Second, you can use this USB-C port for data transfer, although I haven't had any reason to do so yet.
Chapter19659003PGHDMI. Chapter19459005] The HDMI port is located on top of HyperDrive, unlike the other ports, which are on the side. This HDMI port supports 1080p @ 60Hz, 2K @ 60Hz or 4K @ 30Hz. The iPad Pro can actually support a better resolution than that: 4K @ 60Hz. However, due to technical limitations, the iPad Pro is only supporting this mode with a dedicated single use adapter, not a multi-port hollow. This restriction has been irrelevant to me; I don't have a TV that can handle both 4K and 60Hz. If this restriction matters to you, then I need to buy an adapter for one purpose.
I use this HDMI port to give keynote presentations and an external projector, which works great, and sometimes also to connect my iPad Pro to a TV to watch video on a TV outside my home that does not have an Apple TV, such as a TV in a hotel room. I also own the adapter made by Apple that lets you connect HDMI to an iPad Pro – Apple USB-C Digital AV Multiport adapter – and HyperDrive seems to work just as well.
A small blue light on the side indicates that the device is properly attached and powered.
When connected to the iPad Pro, the connection is solid and will not fall off. You can certainly have the iPad Pro in your hand around an office with HyperDrive attached.
HyperDrive is slim enough that I don't have trouble using it with my iPad Pro in App le Smart Folio It also works well with Apple Smart Keyboard Folio.
Because this device is made of metal, you do not want it to bump into the side of the iPad Pro too much because it may scratch the iPad Pro. But this is not a problem because Hyper includes a removable and replaceable plastic grip that secures the device on the iPad Pro without the risk of scratching the iPad. If you want to use this device with anything other than the iPad Pro, or if you have a very large case on the iPad Pro that prevents the plastic grip from working, you can remove the grip and replace it with an included extension cord. It takes away a lot of the design appeal – I love that this product is close to the side of the iPad Pro – but it gives you an extra way to use HyperDrive. ]] We don't know when Apple will release a new version of iPad Pro, and when it comes out, we don't know if Apple will change the design. But even if Apple does, hopefully Hyper can just make a new grip (or you can always use the extension cord), so this seems like a product that will remain useful for a long time.
$ 90 seems like a very reasonable price for this adapter. As mentioned above, I also own Apple's HDMI adapter, and it costs $ 79 (or $ 60 on Amazon), and all you get are HDMI, USB-A and USB-C. And Apple's SD card reader costs $ 39 on Amazon. And Apple USB-C to 3.5mm headphone jack adapter for $ 5.99 at Amazon. HyperDrive gives you a simple product that does everything the three adapters do, plus more because you also have a Micro SD, all for less money. And because the Apple adapters stick out of the side with a short cable, they're more cumbersome to use and carry around than HyperDrive.
If you do not need all six connectors on HyperDrive, you can find cheaper options. Although I haven't tried it, I see that Satechi sells a similar hub for $ 60 that attaches to the side of the iPad Pro and provides four ports: headphone jack, HDMI, USB-A and USB-C. If you don't ever need SD and Micro SD memory card slots, you can save $ 30 by getting the Satechi model. I want those ports, and I love that I can only have a single node to give me all the ports that I will probably use … unless I come across an older projector that only has VGA.
Conclusion  If you own the 2018 version of iPad Pro and you want to use the USB-C port to its fullest, this is a very useful accessory. The iPad Pro is easy to hold, and even when you remove it, it's so small that it's easy to store in your suitcase or purse, so it's always there when you need it.
