SonyMRWG2 CFexpress Card Reader

Got this to read my Sony FX-3 cards. It did sting a bit to pay this much for it, but it's built like a little tank, and has worked flawlessly all this time. Well made. Wish it were dual slot, especially for the price, but it is what it is. I don't know if there are cheaper options out there at the time of this writing, but when I purchased it, it was one of few options. No regrets.

Forget about cheaper alternatives if you're concerned about reliability and speed. This Sony is bit more expensive for a reason. It's built like a tank and it won't overheat your media like the cheaper models will. Plus, it looks great while performing great.Note to media managers...this card reader is the only way to go.

It's worth it.

I needed a card reader that could transfer video footage off my DSLR and videocam SD cards at or near the advertised read speeds. I tried the San Disk / Western Digital Pro reader and had high hopes. Boy was I disappointed. No matter the OS, port, card, cable that thing never read my 200 MB/s reads cards higher than 95 MB/s.Confused I started to wonder if that device was incapable of reaching the card advertised speeds which seemed odd. I can understand a 10-20 MB/s off, but this was less than half the advertised speed. I looked around for alternatives - at around $80 was something several folks said melted while in use, so that was out. So I had to pony up for this Sony card reader.The Sony MRWG2 was able to read and write very close to the advertised card speeds to my delight. It comes with not just one but two cables (USB A and USB C) which is very thoughtful. It is more compact than the San Disk Pro reader. The SD card slot is the spring load type, so you push the card all the way in and it gets "locked" into place. You need to push it to eject it out with the spring. This is like most cameras and other professional equipment. I prefer this over the simple slide in, slide out card slots like the ones on the other card reader I tried.I didn't plan to spend this much on a card reader. However considering my experience with the $50 alternative from a well known brand, I rather pay the price and have the ability to transfer off the cards at or near the advertised read speeds.Attached some speed tests with this card reader. Cards were advertised to support 280 MB/s R and 150 MB/s W and 280 MB/s R and 205 MB/s W.

Works like a charm. Even reads cards my other reader thinks are bad. The single slot will take BOTH the CFexpress and SD cards. I didn't know that when I ordered. Just flip the SD card upside down and put in same slot. Solid metal case and rubber feet keep the unit in place.

I copy images from CF express Type-A and SD UHS-I & II. It reads memory cards faster than my previous Sony SD-only reader. The mechanism seems very robust. In fact the spring is very stiff. Inserting & ejecting a memory chip is really a 2-hand job. The device could use a mounting device.

Recently acquired a sony a7r v. Been thinking of migrating to CFexpress A cards but the price is too high right now so sticking with the SD cards I already have (300mbps rate) for now, but wanted a reader that's future proofed for me.Image file size is 121mb, each, uncompressed raw! Yikes!My original reader is an insignia I bought like 3 years ago. Wanted a new one for a project where the client would like on site image file transfer/delivery. Time is of the essence.On (z690 motherboard) desktop pc:Best buy's insignia reader (discontinued) transfer clocks in at about 41mbps. Took 15 mins to transfer 30gb. Sony's clocks in at 121mbps. Took about 5mins to transfer 30gb. Nice!On my laptop:Insignia reader craps out and fails to read entirely. Sony transfer rate comes in at about 245mbs! Took 2 mins to transfer 30gb!The reader is solid built, never got warm and is a nice svelt size that's easy to carry around. It cost a lot but I couldn't be happier with this reader from Sony!

Solidly made and I trust it with my more expensive CFExpress Type A card. One of the few products in the makers now that support this type of card. Reading and writing blazing fast and I am totally satisfied with it. Expensive but worth it though.
