SD cards are incredible slow. 

 

You might want to reconsider and use a USB 3.0 Type-c flash drive instead.

 

You will need to use an adapter which normally is delivered with a high capacity Micro SD card.

 

The following video will give you some information about the SD card specifications.

You  will want to use the fastest and highest capacity card you can afford for your upgrade project.

 

When you put the card in the adapter and plug it into the SD card slot,

it  will be close to a flush fit and won't stick out at all.

thanks for your reply and advice.

I got confused though. you mention to consider a "usb3.0 Type-C" & "an adapter which normally is delivered with a high capacity Micro SD card".

do you mean to put a micro SD card in an adapter and connect that to the USB-c on the right side of the 840 G4?
that would mean your still using an SD card right?

Sorry. Did not mean to confuse you.

 

The USB 3.0 Type-C usb flash drive has very high data transfer bandwidth @5 GB/s

 

"do you mean to put a micro SD card in an adapter and connect that to the USB-c on the right side of the 840 G4?"  No. Putting it in an adapter won't make it transfer data any faster.

 

I have used  SD cards for  android emulators  and virtualizations before and I, along with many others, have noted that the data transfer speed is slow, even with a class 10 SD card. (@90 MB/s)

 

The adapter that I mentioned is usually delivered with an SD card in the package. 

 

Current SD cards (micro) are too small to be used in a notebook PC without  an adapter.

 

I hope that makes my explanation more concise.

Sorry about that. It is in Dutch. That perticular spec is reading 130 mb/s.  and it is USB 3.1 (Gen1, 5Gb/s).

 

That is still considerably faster than a class 10 SD card.

 

The cards on the following linkl would be much better. They connect to the USB Type-C port on your notebook.

i see. thanks for the clarification. 
the only downside is that it will stick out of the laptop body quite a bit.

I'll have to consider....

 I can understand that.

 

The smallest USB 3.0 type-C flash drive I have sticks out about 2.5cm when plugged it to a USB 3.0 Type-C port.

 

SD cards are indeed unobtrusive, but the trade off is the dramatic difference in data transfer bandwidth.
