Recently purchased a Transcend 1000x card. Noticed that with my Lexar Pro USB3 reader that write speeds are great (75MB/s or so), but download/read speeds are terrible, to the tune of 5MB/s or so. My Sandisk cards are perfectly fine, and my Extreme Pro runs at 75MB/s for both read/write.
Any ideas on where to begin? With components from two manufacturers it's unlikely either will be overly helpful.
