Sony MRW-G1 Reviews
Works great, card gets hot
It has worked well for me for both supported card types. I saw in another review where the reviewer heavily dinged the reader for its performance with a USB-C to USB-A cable. I just compared both connection types on my PC and don't see nearly the degradation reported in that other review. I copied 4.5GB off of a CFexpress card with each cable type, the C-to-C averaged 190 MB/sec, the C-to-A averaged 120 MB/sec. So the C-to-A was about a third slower. I'll speculate that in the other case it wasn't connected to a USB3 port when using the A connector or it wasn't recognized as being a USB3 device in that case. I try to remember to eject the card as soon as I'm done copying as it will heat up quite a bit. I saw comments in reviews of other CFexpress readers noting the heating issue. May just be part of the tech, not necessarily due to the reader.
Yup. Leaves regular readers in the dust.
A Necessity for Fujifilm H2 Camera
The reader is excellent but not cheap. I don't enjoy buying accessories that seem a luxury. I can download photos off my Nikon D850 XQD card with a USB cable. Not so with Fujifilm X-H2 and the CFexpress Card Type B. Apparently there is a problem with the Mac OS and USB transfer is not possible. When I called Fuji, they acknowledged and explained the problem suggesting that i purchase a card reader. A Plan B is to copy photos & videos from CF to SD in-camera then read the SD in my computer which works but it is not a satisfactory procedure. So I bought the SONY reader because it conveniently reads both CF & XQD cards.
Good card reader
Does a good job of reading the newer Type B cards and XQD. Fast.
Works great, but unfortunately missing a SD card slot which would have made it much more functional. Many of us have cameras that still use SD cards as well as CF/XQD and having to have 2 different readers is a pain.
Sloves my problem
I needed a reader for both cards and this one work great.
Exactly what I needed
Runs fast, can recommend
Compact and portable.
Works well all the time.
