Kingston 266X 4GB Compact Flash Card
Sisoft Sandra is a synthetic benchmark utility capable of reporting and benchmarking a wide range of system components. For the CF cards I ran the "External Storage" benchmark.
Let's see how the cards did.
The PNY card drops behind by a long way on this test in what starts to be a pattern. The Kingston and the Sandisk cards are far faster with the Sandisk snatching a 100 point lead.
HD Tach is an excellent free program that shows the speed of any drive connected to a PC. We ran it and recorded the Burst Speed and Average Read.
Here as well the Kingston is just pipped to the post by the highly rated Sandisk product.
I copied a file to the cards and then copied it back from the cards and recorded the times taken. Let's see how they got on in this real life situation.
In this test I put each of the cards in my Canon EOS 400D and saw how each felt like when taking photo's (see page 3 for details).
PNY CF Card
The PNY card kept it consistant by being laggy and slow to write after the camera took a picture. I would go as far as to say this inhibited taking pictures.
Sandisk Extreme III CF Card
The Sandisk card was snappy and responsive and meant I could utilise the excellent EOS 400D to it's full capabilities.
Kingston 266X CF Card
The Kingston was also snappy and felt almost identical to using the Sandisk card.
Overall I have been impressed by the Kingston 266X 4GB Compact Flash card. It's speed and versatility is excellent and it is a match for faster (and smaller capacity) cards on the market.
