Kingston 266X 4GB Compact Flash Card

Introducion, packaging, package and specification


Kingston are one of the worlds largest manufacturers of memory and flash memory with a huge annual turnover of $2.2 billion. We've taken a close look at many of their RAM modules with some really hitting some big numbers in our tests.

Now it's the turn of the trusty Compact Flash Card (CF). Those of you with DSLR's will know having a fast CF card in your camera is an essential if you want to take a lot of photo's fast. Let's see how it gets on pitted against one of the best on the market - the Sandisk Extreme II CF Card.


Kingston have opted to go with a blister-style package on the 266X CF Card. This is good as it protects the card and also shows off what you are getting.

Limited information is available on the back of the packaging but the basics are there. Kingston have chosen to keep it a little low-key but it looks nice and certainly the card itself is coloured to stand out.


There isn't a whole lot to the package in with the Kingston 266X CF card. You get:

* Kingston 266X Compact Flash Card
* Short Instruction Manual
* Plastic CF Card holder

And that's it. In all fairness you don't get a whole lot in other card packages although Sandisk do give you a bag with their Extreme II card.

Now let's see the specs before we go any further:
