If you are like me and when downloading your pictures you want to see them right now get this reader. In the case of the external SSD drive, the USB 3.0 interface could be a limiting factor and depends on the. With mechanical hard drives, that cannot reach SATA 2.0 speed, its not an issue both types of interfaces should have the same speed for the given drive. Also, if you are using a slower speed card the speed difference will not be that great. The USB 3.0s nominal speed of 5Gbs is still slower than eSATA 3.0 speed of 6.0Gbs. If speed doesn't matter to you and while downloading you can go and do something else than stick with what you've got, also remember that your computer must have a USB 3 port. When Deklins reader became available, I bought it right away. I've seen other USB 3 readers on the internet from companies I've never heard of so I passed on those. If you take a lot of pictures and when downloading them you want to see them NOW, then GET THIS READER.

The card I was using was a Lexar Professional UDMA 600X 32 GB card. The second was a Lexar Professional UDMA reader and finally the Delkin USB 3 reader. The first reader was a Sandisk 12 in 1 reader. I downloaded them using three different card readers.

I shot 529 Raw photos with a Canon 7D totaling about 11.3 GB.

About a week ago I received Delkins new USB 3 card reader and decided to do a little test.
