Sonnet Technologies 21-in-1 MultiMedia Card Reader and Writer

"You need to know that the Sonnet 21 in 1 express card adapter runs on the USB bus therefore the transfer speed will only be about 20MB/sec in the real world. If your read a review here and it says this card is fast you have to wonder if they know what fast is. I've tested two of these 21 in 1 cards with the Aja system test program - never seen anything over 20MB/sec and usually it's less than that. Sonnet has a pro version of this card that runs on the PCIe bus - which is much faster for about $20 more - the SDXC UHS-I Pro Reader/Writer. If you're dealing with video and photo files you need to kiss USB goodbye. It's just too slow.



Both Sonnet SD adapters (USB & PCIe) work fine - no drivers needed - insert the SD card into the adapter, then insert into the MBP or laptop. I give it 3 stars only because it's USB2 but it works just fine on my Macbook Pro 17in 2010."

"Just bought this reader after realizing my MacBook Pro didn't have a SD reader. This works fabulously with my Express Card 34 Reader. The reader sits flush with my laptop so I can leave it in. Have only used it once so far but I was able to view images instantaneously and transferring approx 350 images from a Canon DSLR camera SD card took about 30 seconds. Just pop the reader in, look for the icon on the screen, double click and there are your images. No drivers or cables. Only thing is you do need an adaptor with some of the other memory cards like the Memory Pro Duo for the Sony Cybershot point and shoot camera. Haven't used it with the adaptor yet but I don't foresee any issues. Most of the reviews I've seen of this product have been good and I agree with them. Highly recommend it!"

"This express card reader is amazing, I use it everyday. Before I had to hook up my camera every time i wanted to move pictures to my macbook pro. It fits perfectly inside the machine and sits flush against the body.

The best part about this card is that it just stays inside the machine everyday because it is that efficient.



What is great about it is that I no longer have to use an ugly external card reader for my pictures. I can upload on the go with no problems whatsoever.

It does exactly what it says it will, and will add that missing element to any laptop without an SD card reader."

"This is a solid quality product that works great. Before I purchased this card, I was using the USB connection directly to the camera. This card transfers the pictures much quicker and works seamlessly like any other external drive.



I have not had problems with this card, but have experienced customer support from Sonnet Technologies on another ExpressCard/34. Their tech support is fast and extremely helpful. I highly recommend this product AND this company."

"I bought this reader for my Macbook Pro (2.4GHz Core 2 Duo) to use with the xD cards of my Olympus camera and the SD cards of my various other devices. The Sonnet reader works great with those two card types. The plug-and-play works perfectly. The other advertised compatible card types I have not used yet.

I transfer 1Gb files to/from the cards all the time with any trouble. Transfer speeds seem a little slower than USB readers but its not slow enough to make me switch readers.

The reader is almost flush with the side of the laptop. It only sticks out about .5mm. Its fine sliding the laptop in and out of the travel sleeve though.

Overall a great device. A great and unobtrusive solution for Macbook's missing memory card slots."

"As far as I kow, it's the only product that connects memory cards effectively to the now 'estranged' ExpressCard slot on Macbooks. Every time you put a card in mine it pops out, then when you pop it back in, just push on rim of express card only and both cards will stay in and work. It fits extremely well to the body of the macbook. I've downloaded HD video faster than usb cable alone.



in short very effective, with only mildly annoying popouts."

"Nothing special here.. the product does what it should. basically plug and play.. fits flush to the side of my mac book pro when there is no card installed. When my SD card is installed, it hangs about 1/4" over the side of the laptop.

When putting the SD card in there is a possibility of pushing the card in to the card reader too hard/far, and causing the card reader to eject from the express card slot. While this is a little inconvenient you can get used to the amount of push required and eventually eliminate this problem.

Nice product, does what it should. Transfer rate is fast."

"Overall I think this little card is a great idea. It fits flush within the express slot so you don't have to keep taking it in and out. It's compatible with a wide range of cards. My issue has been that the SD cards I use apparently fit so tightly within the reader that it is impossible to insert or eject cards without first taking the reader of of the computer. Just a few extra micron space in the insertion slot would have made all the difference."

"I use it to read the SD card from my camera. I leave it plugged into my laptop and it also required no drivers at all when I plugged it in. When I slide the SD card in the pictures pop right up on the screen. Very quick response reading the contents of the card. So far it's working just great for what I need. Haven't experienced anything not so great yet."

"I have a 17" MacBook Pro and this model includes the ExpressCard/34 slot instead of the SD reader slot. I don't expect I'll ever need the ExpressCard, and I frequently need an SD reader, but this isn't exactly a build-to-order choice. This card reader is in my view, an permanent adapter. I appreciate that it remains flush in the side of the notebook (except when there is an SD card in the adapter). The performance is just okay- it seems that it is subject to random slow-downs, but they aren't frequent or lengthy. There are no drivers or configuration hassles on the Mac. Certainly worth the price."
