Sony MRWE80 reader, this is the one that I purchased separately. 32 GB Sony G card (the older 400 MB/s version)ġ. 32 GB Lexar 2933x card (rated to 440 MB/s)Ģ. Note that this means that the times aren't exact, I shot over to the timer as quickly as I could, but there's probably about a +/- 2-3 second error for each recorded timeġ. I used the Google Search stopwatch to time, and monitored each transfer using the Windows explorer file manager status window.I ran through each of the 3 card readers with a Sony G-card, then a Lexar 2933x card.

The file that was copied was a 4.65 GB archive file.The reason that I chose this file system, though it is different than it will be when formatted for your camera, but I was using a single file that was too large for the FAT32 file system. Before each test, I reformatted the XQD cards in exFAT.I own a few Sony G-readers, but I only tested one of them. Note that I didn't do a TON of testing, 1 file copied to, then back off of, 2 different cards in each of the 3 reader types that I own. I now own more XQD readers than cards, but I own different ones, so I decided I would compare them and see what would happen. When I ordered my first XQD cards, I didn't realize it would come with a reader, so I also ordered a reader. So, I've seen some tests of various XQD cards, but not of the readers (NOTE: since starting this, I found I am wrong, but maybe this will still be useful info - does provide reader info).
