Question: How many different types of cards does it read
Document: This is a perfect accessory to have for any computer. I have had people give me picture and file on so many different cards that I can now transfer them without any worry as to how I am going to accomplish it.
I do not like the software that comes with many digital cameras that forces you to connect the camera to your computer to transfer your photos. The card reader built into my computer does not read the newer SDHC cards, so I needed an external card reader.Installation could not have been simpler: plug one end of the supplied mini-USB cable to the reader and the other to your computer. Wait until a message shows the device is ready and you are done.
I use this for several different Mac's that I use and it works flawlessly for transferring data from a variety of memory sticks that I have (digital cameras, sd cards for picture frames, etc.) Highly recommend!
Does what its suppose to...read cards.Looks cool on my desk.Don't really care about fingerprints.If it really starts bothering me, I'll use some Windex.Exactly what I was looking for.5 stars all around.
I love this product!It arrived on time and properly packaged.Set-up was easy and it is lightning fast in downloading photos, even large ones taken with my Panasonic FZ35.I only need to use a couple of the ports right now, but I like that it is able to accomodate many sizes of memory cards.I have used it to write data and photos to also, and it is fast and easy.Definitely recommended.
I ended up returning this reader because of its inability to read a SanDisk 16GB micro SD card (mSDHC) in the mSDHC slot. SanDisk technical support confirmed that the SDDR-189 has a flaw in it's mSDHC controller where it cannot handle the initial power up of certain current generation mSDHC cards. The workaround offered was to utilize a micro SD to SD adapter and place it in the SD slot of the reader.
SanDisk's website allowed that there was a firmware flash upgrade available for the 12-in-1 that would allow it to read memory cards with the newer protocol, but unluckily my particular reader was old enough that there was no flash available for its serial number range.I bought a nice looking all-in-one reader made by IOGear (their "56-in-1 Memory Card Reader/Writer"), and it worked with the new card, but the transfer was agonizingly slow.
I had to upgrade to this model from a much older version because I needed the SDHD support, while also being able to read micro, SD, and CF cards.Data transfer speed is lightning fast, especially when compared to cameras and other digital media using their own transfer to PC. Its functionality is not short of great, and what I would expect from SanDisk.While the unit itself is compact, its industrial design isn't quite what I would expect from SanDisk.
When I was done I ejected the icon and pulled my card from the slot. So easy even a caveman.....One final thing that I cared about: It accepts both SD and Compact Flash cards. Many of the digital SLR bodies out there take Compact Flash memory cards and I didn't want to need another card reader cluttering my desk when I finally break down and get theNikon D700 12.1MP Digital SLR Camera (Body Only)I have been lusting for.
I knew there were some issues with the design of the stand, but I was not expecting the difficulty in inserting and removing the SD card. I bought 4 different brand card readers to evaluate for our business, and this was the poorest of the 4. I ending up purchasing several more of the Transcend USB 3.0 Super Speed Multi-Card Reader for SD/SDHC/SDXC/MS/CF Cards (TS-RDF8K) as it was the best of the 4 I tested.
