A while ago I decided that 2GB of storage on my smartphone just wasn’t cutting it, so an upgrade was in order. Queue Sandisk’s 8GB Class 6 “Ultra” Micro SDHC card. The “Ultra” part does indeed sound like silly marketing talk, although I’ll explain I think it is warranted. SDHC classes exist to give you a guarantee of the lowest write speed of your device. For example, you are guaranteed a minimum write speed of 6 megabytes per second if you have a class 6 card.

I have been testing my class 6 Micro SDHC card with a file-copying application called “TeraCopy“, and I have always had a consistent and sustained write speed of 15 megabytes per second. That’s two and a half times faster than it is guaranteed to run. Just to give you an idea of what this means in practice, I copied about 5GiB of music onto this card in less than 5 minutes.

Now for some pictures:

This is the packaging the card came in. On the left is the card itself in a protective case. On the right you find the tiny USB adapter, and below is a lanyard attachment for the adapter. The USB adapter was the other attractive parts of the package. If you don’t have any SDHC capable equipment, this lets you make your Micro SDHC card into a tiny USB drive.

Here is a size comparison the adapter. Top to bottom order: Micro SDHC USB adapter, Logitech VX Revolution dongle, Sandisk 4GB Cruzer.

Here’s how the USB adapter looks plugged into my laptop. Again for size reference, you can see the mouse dongle plugged in beside it, and another SD card in my laptop’s SD slot.

Finally, here’s an extreme close up of the card, just to try and show you how small these things really are..
