E4200 SD card speed
My E4200 has a 64gb SSD which I am using for OS/programs etc, so I am using its SD card reader for data storage. Obviously the faster the better - SD cards come in a range of read/write speeds which need to be matched to the reader for best performance. I have asked Dell support for the specifications of the reader and so recommendations for the card, but they have been unable to find out what the reader can do. I would have thought that this sort of detail would be easily available in the published specs.
Has anyone found out the SC read/write speed? I need a larger card and the faster ones cost a lot more. Waster money if the E4200 cannot cope.
Thank you

Tough to tell, but I just received a 16GB SD UHS-1 card from SanDisk and I can't get a stable write above 7.75MB/sec and a read of 10MB/sec using my e4200 (Win 7-64 bit).
I used two different file sets, 1 3.75GB file and 400 3MB files. Both yielded the same speed.
Hope this helps.
