Is my Extreme Pro 90 MB/s 32GB Compactflash an Ebay fake??

I purchased this card off Ebay,read speeds seem to be fine(90+ mb/s),but the write speeds seem to max out at just over 30 mb/s.I also have a Lexar Professional 600x card that has read speeds at just over 80 mb/s,but its write speeds are almost the same at around 75 mb/s using the same card reader.Any thoughts…


The card looks genuine. Did you format the card before doing the test?

Yes,I formatted and tested it a few times with the same results consistently.I did contact Sandisk,and they looked at the pics and serial number and confirmed its real and does have a speed issue.They have agreed to exchange it for another one,and were very helpful and quick to respond,very impressed with there customer service.

That happens whe you are not using niche fnder tool. Always use niche finder tool which will you to find potential buyers in your niche.
