To see how quick the performance of the SanDisk ImageMate Multi-Card USB 2.0 Reader/Writer is, we will be comparing it to the Kingston USB 2.0 Hi-Speed 19-in-1 Media Reader. We reviewed the Kingston USB 2.0 Hi-Speed 19-in-1 Media Reader back in 2007 when it first came out and found that it was a super fast reader. using the SanDisk MobileMate USB 2.0 reader on both cards.
Each reader was tested using Sisoftware Sandra 2009 SP3 on our office computer with the SanDisk Extreme III 30MB/s Edition SDHC card. The SanDisk Extreme III 30MB/s Edition SDHC card is rated up to 30MB/s or 200x speeds, which should be plenty for this test. This is a Class 6 SDHC card, which is one of the fastest and most expensive SDHC cards on the market today.
Using the Removable Storage Benchmark found in SiSoftware Sandra 2009 SP3 we were able to get a pretty good idea of the performance that the SanDisk ImageMate Multi-Card USB 2.0 Reader/Writer offers with various file sizes. As you can tell from the chart above, performance generally increases as the file size goes up. In the 64MB Files Test the Sandisk reader was 39% faster than the Kingston reader when it came to reading files of this size.
When it comes to write speeds the SanDisk reader once again dominated. The Multi-Card reader is capable of up to 27 MB/s
write data transfer rates when using a SanDisk Extreme III 30MB/s
Edition SDHC card, but our test system couldn’t duplicate that with this benchmark. With a 256MB file size, the SanDisk reader was able to write at 17.00 MB/s, which is 33% faster than the Kingston reader.
To confirm the Removable Storage Benchmark that was used in SiSoftware
Sandra 2009 SP3 we ran the Flash Memory Toolkit v1.20 file benchmark on the SanDisk Multi-Card reader. This
benchmark tests 1-5MB file sizes, and showed that the SanDisk Multi-Card reader did best in the 4MB file test and showed a write speed of 19.9MB/s and a read speed of 27.1MB/s.
