Is your memory card slowing you down?

Did you know your memory card could be slowing down your mobile or tablet? If you have a slower class memory card it significantly reduces the speed of writing and reading data.

  • Phones
  • Cameras
  • Tablets
  • Gaming devices

Most of the above pieces of equipment have extremely limited data storage. You will most likely need a bigger memory card to get the most out of the storage facility.


You may notice most memory cards have stats printed on them relating to sizes, types and speeds. Make sure you check with your device for what writing speed it will need. The memory card needs a ‘write at’ speed that can match, if not exceed, your device write speed.


My Canon 5D MKii can easily produce up to three frames per second, each frame 25mb in size (Raw). My memory card needs to be able to store the write speed of data in order not to slow me down.


The Canon 5D has a buffer which temporarily holds the data information before the camera writes it to the storage card. My buffer can easily hold 14 shots before it starts to lag, so my memory card writing at 60MB/s is fine. However if I put in a memory card writing at 10MB/s I would notice a significant delay in write speeds. I mostly use SanDisk Extreme as above but I am however currently in the process of trying out some Lexar Professional 800x Cards too. I will let you know how that performs soon.

It’s important to think about buying genuine and reliable memory cards. Check out My Memory links before to make sure you have the best card for your needs.

How to Adapt Memory Cards

With the vast range of memory cards these days it’s hard to get a real idea of which you need for which device.

Most gadgets take varying types and sizes of memory cards. We find ourselves not being able to use the same memory card across our devices and gadgets.

Did you know cards can be adapted to enable a smaller card to be used in an item designed to house a larger one?

Here’s a quick example of my Micro SD and Micro SDHC adapter.

Micro SD and Micro SDHC adapter.

Micro SD cards are about a quarter of the size of a standard SD card and are most commonly used in mobile phones. I use the Micro SDHC to SDHC card adapter to use my phone and tablet cards in my integrated laptop SDHC reader.

I checked the speed with and without the adapters and the write speed was unchanged.

Chosen carefully, an adapter is a handy accessory to have available, which can be used to service a range of electronic gadgets simply and reliably.
