Performance Testing
To see the performance of the of the SanDisk Extreme 30MB/s 32GB SDHC card, we will be comparing it to an 8GB Class 2 Lexar SDHC card and a 4GB Class 6 SanDisk Extreme III 30MB/s Edition SDHC card. The SanDisk ImageMate Multi-Card USB 2.0 reader/writer was used for testing all of the SDHC memory cards.
Using the Removable Storage Benchmark found in SiSoftware Sandra 2010c we were able to get a pretty good idea of the performance of the 32GB SanDisk Extreme SDHC card with various file sizes on our test system.
As you can tell from the chart above, performance generally increases as the file size goes up. The 32G Extreme and 4GB Extreme III SDHC cards by SanDisk had similar performance as both at rated as having speeds up to 30MB/s. As you can see when running file sizes great that 64MB in size we would appear to be limited by something. It could be the card reader, the card itself or the test system that is the limiting factor here. The Lexar 8GB Class 2 SDHC memory card had half the transfer speeds in the 256MB files test, which shows why a higher speed rated card is important.
