PerformanceTo test the capabilities of this Super Info SD card. I connected it to my PC via a SanDisk 12-in-1 card reader which is isn't a bottleneck for performance since it can cope with almost 40MB/s bandwidth. To bench the memory cards I have used HDTach 2.7 which is a really good benchmark program that not only measures the bandwidth of the card but also calculates CPU usage and response time of the card.
In order to test the cards with different package sizes I have used ATTO benchmark system which generates multiple scenarios with different package sizes and measures the read and write performance of the card.
The card will be benched against my A-DATA 1GB reference card and the new OCZ Secure Digital Dual 1GB. A-DATA doesn't list this card's speed anywhere, so one could get an idea that they have something to hide, but after many benchmarks I can only conclude that this isn't the case. This card performs just as good and even better in some scenarios than the OCZ and my A-DATA reference card.
This card really performs and almost out did my 1GB ADATA card in the read speed test done in HDTach 2.70, read bandwidth was really good at 11.9MB/s, which equals 80x speed by the old calculation method (150KB/s * 80 :1000=12MB/s). This card easily outperformed the OCZ card in the read bandwidth category by almost 4MB/s.
The Random Access Time (RAT) of this card is the best I have ever seen by a SD-card, the random access time was a mere 1.3ms which is very good for a SD-card. With such a good RAT this card would be ideal to spice up the load time of Windows Vista, if you i.e. have a laptop with a SD-card reader.
As you can see from this screenshot of HDTach 2.70, the card has a very smooth performance curve which means that the read bandwidth is the same across the entire medium.
The ATTO benchmark was run with the default configuration. In ATTO the card performed just a little bit worse than the OCZ Secure Digital Dual 1GB. The write speed of the card was way below that of the OCZ card. Another area of performance where the A-DATA card is a bit behind, is the read speeds when the chunk of data are large.
