Windows 7: Best way to test SD Card speed/bandwidth

Best way to test SD Card speed/bandwidth

Howdy,

I'm wondering if there are any way to test the speed/bandwidth of an SD card with built-in Windows 7 utilities/diagnostic software?

And in the absence of that, what are the best (and safest) freeware utilities to do this test?

I'm not having a problem with my machine, simply want to figure out which of my SD cards are the slowest and fastest so I can decide which to use and when.

Many thanks!
Doug

Hi OldDogEyes, I have used this little app in the past to verify if a pen drive was genuine It will also tell you the transfer read/write rates H2testw - Fix Your USB! If you have a usb adaptor for your SD card it should work on that

Windows XP Will Soon be Windows 7
 
 

If you are using Windows 7 or Vista, make a file at about 500 mb in size, or find any large file. Copy it in to a new folder for testing. Open the folder that is the SD card root directory. Copy the file accross from the folder on the hard disk to the SD card root. While copying, look at the details in the copy notice window. Down toward the bottom it will display the mb/sec of copy speed.
