For those of you not in the know, most current SD cards implement an Ultra High Speed bus (which is abbreviated UHS-I or UHS-1) because it is the 1st version of this bus. It has a maximum transfer rate of 104MB/sec. Since there are some cases which require higher transfer speeds, the SD card consortium has created a new bus called UHS-II (or UHS-2.) The difference is two-fold:
- UHS-II raises the maximum transfer rate up to 312MB/s.
- UHS-II uses an additional row of pins/contacts to get there.
This means that UHS-II cards can only be fully utilized if the device using it has physical support for these extra pins/contacts. If the device does not have these extra pins (and that’s pretty much all devices as of 2014), then the SD card will fall back to UHS-I mode.

Three USB 3.0 SD card readers were picked from the pile (all around $10), put under the microscope, and then a bunch of SD cards were thrown at them to see what happened. Surprisingly, each SD reader had its own advantages and disadvantages with no clear winner. Choosing which one will come down to personal preference, mostly.

If you’re not shooting pictures with your cellphone camera, then it’s probably a good bet that you’re probably using a digital camera that takes SD memory cards for picture storage. There are lots of SD card manufacturers out there, but perhaps the most popular SD memory card manufacturer is SanDisk.
Looking at SanDisk’s website, it appears that they have quite the line-up of SD cards. One would think that 3 different SD cards would be enough to sell to a camera-happy world, but SanDisk seems to think that 6 different cards is needed for all your different photo shooting needs. So which card to buy for your camera?
