4.0 out of 5 stars
Not quite 20MB/Sec but still good, 28 April 2011
Copied 8gb to the card consisting of 60 files from 80mb to 800mb using Windows Vista and took 9mins. Avg write speed was 14MB/sec.
Copied the same files back and took 8 mins with avg read speed of 17MB/Sec. Not quite 20MB/Sec but still good v.good value. The card comes formatted as FAT32, I formatted it as NTFS as that's more efficient for large storage. Don't know how much that would effect speed but card seems to work fine in my laptop.
