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.
The write performance between the SanDisk Extreme III 4GB and Extreme 32GB SDHC cards seemed to be a mix as both cards took the performance lead in at least two of the file size tests.
Wanting to run another test on the SanDisk Extreme 30MB/s 32GB SDHC memory card we ran the CrystalDiskMark 2.2 benchmark. This benchmark tests a few different file sizes, and once again showed that the SanDisk Extreme 30MB/s 32GB SDHC memory card was capable of a write speed of 26.19MB/s and a read speed of 27.37MB/s in the sequential read/write test. This card is very fast as you can see from the testing!
