Is anyone else using the same setup and what kind of speeds are you getting. I am now wondering if my D500 is really seeing any benefit from the XQD card if the write speed is so slow. It always errors out! The Link So I guess it's the lack of a USB 3.1 port or the driver or maybe just Sony screwing over Lexar users? I don't get it, the USB 3.0 is supposed to go up to 640Mb/s in the dream world so I expected at least 250Mb/s in the real world. I then plugged my Seagate Backup SSD drive into the same port and can write the same file at 70Mb/S and read the file at about the same 70Mb/s on average with a burst of 140Mb/s for the first half of the file.Īt this point I am scratching my head and wondering if the reader needs a specific driver so I start reading and see one or two mentions of a driver but the link for the driver was not easy to find and when I did find it the page is not operating properly because you just cannot select an OS and the download. I then put a Lexar SD 64Gb x1000 card in the Sony and I get about the same performance, it actually was a tad bit faster than the XQD which was surprising.

The read speed of the same file starts off at 150Mb/s for the first 100Mb and then drops to 60Mb by the end of the transfer. I then put in my Lexar XQD 64gb 2933 card in the unit and wrote a 2gb file to the card and the transfer speed starts slow the moves up to about 36Mb/S on average. The unit was auto detected and drivers installed without a problem. I just got the Sony MRW-E90 dual reader and I have tried it on two PC's running Windows 7 (64bit) with USB 3.0 ports.

Most readers support USB 3.0 or USB 3.1 for maximum transfer speed. Card Reader Reviews These Secure Digital, microSD, CompactFlash, XQD and CFast card reader reviews include read and write speed tests using several memory cards.
