My primary camera is the wonderful Nikon D7100. This has dual SDHC slots, and these now form the first step of my backup strategy. These slots are filled with SanDisk SDHC cards, in various sizes from 16GB right up to 128GB, and various speeds.
Note: I have no association with SanDisk other than as a very happy user of their cards. All of my cards were bought and paid for personally.
The cards in that case are not pristine – they have spent the last 18 months being slid in and out of cameras and card readers so are a bit scratched.
I have no hesitation in recommending SanDisk, so far I have had no card errors, and no lost images when using them. I have been using Sandisk almost exclusively since 2004, although a brief foray into some ‘own brand’ cards was explored, I wasn’t happy with the overall performance of them so went back to Sandisk. I always buy from Amazon, as there have been reports of fakes on many other sites.
I have used their cards in 40°c desert heat, -15°c windchill within the Arctic Circle, in jungles, underwater and even down my local park. Not once have I ever had cause to doubt their quality. The benefit of using one of the big players, such as SanDisk or Lexar, is that being globally recognised their brand name means a lot ot them, so they will stand behind their products.
Whilst off-brand cards may seem like good value, I feel they are a false economy. The £20 difference for an absolutely top class memory card pales into insignificance when compared to the price of a 2 week trip somewhere exotic, or the cost of lost images for a paying client. The pro’s know this, it’s why they don’t skimp on cards and will only use top brands such as SanDisk and Lexar.
One other benefit of better cards, is that they are generally faster. Whilst this might not seem important to many, for those who shoot heavily, or take multiple shot bursts, the quicker cards mean less time spent waiting for images to download, and less time waiting for the camera buffer (which is pathetically small on the D7100) to empty. To this end most of my cards are SanDisk Extreme Pro 32GB 95mb/s, although I do have some cheaper, slower cards for use in one of my backup strategies.

I keep my cards in a hard case, placing them face down once used – my current memory card case
