By that time I had also noticed two subtle differences between the 4 cards, even though all boxes were the same: Alarm bells started to ring when the new 60MB/s cards turned out to be slower than my older Extreme IV 45MB/s card.
They seemed a bit slow, so I benchmarked them by dumping 2GB chunks of data using the unix command 'dd' (*). However, there are 3.Īnyway, the order arrived on time, I picked it up at the local convenience store and started playing with the cards. I need to find out what my product's serial number is in order to register it. I purchased an Sandisk Extreme Pro 256GB. I thought that was an extra guarantee compared to the standard 'marketplace' stores found on Amazon, and as you can imagine I was wrong. However, the shop actually owning the cards was not Amazon. The order was 'fulfilled by Amazon', which means that the goods are stored and shipped from an Amazon warehouse. I bought four 16GB, 60MB/s Sandisk CF cards from Amazon Japan in November 2012. Obviously buying from Ebay is not the brightest idea, but major (online) stores are also selling fake Sandisk cards don't think it only happen to others. The first thing to realize is that no one is safe. And maybe even prevent you from clicking the wrong 'buy now!' Unfortunately most of you will read this page after buying counterfeited CF cards, but hopefully my story will help you find the truth about what you bought.
