This card states that it has a speed of 90MBps read and 45 write. I am getting 30MBps write and 75MBps read. I am using a Transcend RDF-8 USB 3.0 card reader and it is compatible with UHS-I cards.
My computer is a Late 2013 Mac Pro (the trash can one) and it copes with basically everything, so the computer is not the reason why I am not getting the advertised speeds. It's a SD card, the only thing I can review about it is its performance and longevity. I've only used it for a few hours so I cannot comment about how long it lasts, but the speed is not what has been advertised. Transcend should change the classification.
Surely they need to test each card before packing, so they can see the speeds they're getting, therefore there's nothing stopping them from relabeling underperforming cards. I have a SanDisk Extreme that promises and delivers 45MBps. I am disappointed with Transcend this time. I doubt that I'll get a pro rata refund due to this issue, but that's what I'd like. If I get something that does less than promised, then the price should drop to compensate for the lack of performance.
I just won't return this because I get a slight increase in read speeds compared to the SanDisk that I'm happy with, however I'd like to receive what I've paid for, so knowing that Transcend reads these reviews, I'd like them to consider my points.
