I get lots of questions about my backup workflow, my travel packing workflow, my post-processing workflow but not enough about my memory card workflow. Memory cards are kind of important – if they don’t work nothing else matters.

It’s not a big deal really but I do think it’s worth a short post just to make sure everyone has at least considered this.

Here’s my basic memory card workflow.

1. Test every new card in at least two cameras – download images, reformat card – make sure it’s solid.

2. Label every card with my name, phone number and month/year of the purchase date. The latter is because I want to know which cards have the most use (the oldest) and the name and phone number is simple – if I am in a group and memory cards get exchanged, lost, etc. whoever ends up with mine will know it and hopefully return it.

3. Find a dedicated storage device for your memory cards and always keep the cards in that device. I use and very much like the Pixel Pocket Rocket from Think Tank Photo. Holds more cards than I need for any shoot but takes up little space.

4. Always, always, always have your memory cards on your person. If you hike three miles find out you left your cards back in the truck and miss a cool shot because you are out of memory this will likely only happen to you once. Additionally – if you leave all your gear in your car and someone steals it and the cards are inside you are out the most valuable thing you could have on any trip – the photos. The gear should be insured and is replaceable. The photos are not.

5. Develop a system for knowing which cards are empty and which full. I simply place the card back in the Pixel Pocket upside down to denote it is full. Works well.

6. Don’t delete single images from your card in your camera or from a computer. Format to delete and do it in camera. This is less of an issue with newer cards but older cards can easily be corrupted and this is one of the ways that happens.

7. Don’t share cards. Unless you’re the type who would also share a toothbrush with a stranger.

8. Keep your cards dry and in reasonable temperatures and humidity so that they function within the manufacturer’s specs.

9. Don’t buy the cheapest card. If you have a $10 head buy a $10 motorcycle helmet. This isn’t a place to skimp. The name brand cards don’t cost that much more than the off brand cards.

10. Don’t buy the biggest, fastest card on the market. Buy the model one down from that. Not only will it cost a lot less per megabyte, it’s safer. Sometimes the new cards aren’t supported by older cameras.

I could go on but I’ll stop here. This is a good starting point. Have a plan when it comes to your memory cards and your odds of experiencing a memory card-related problem will drop to almost zero.

Photographers use memory cards unless they shoot film. So when a new card comes out I pay attention. I’ve tested a wide variety of these cards over the last decade and here are my general conclusions…

1. Most of the cards perform similarly.
2. All are subject to failure eventually.
3. As long as you are using a well-known brand card (like one from Lexar) you are probably as safe as you can be.
4. Abusing cards can lead to their failure but not always.
5. Most cards offer similar speed, performance and reliability.

That all said, two things do constantly change and that’s the size and speed of these cards. Lexar recently released their 1000x CF card which uses UDMA7 technology to offer claimed speeds of 150MB/s. Alongside that release, Lexar also released the Lexar Professional 600x SDHC card which promises 90MB per second read transfer speeds.

Both these products are top-of-the-line cards offering some of the fastest speeds I’ve seen here in the Photofocus testing labs. While all my tests are real-world, i.e., I don’t have a bunch of fancy scientific benchmark equipment, there’s sufficient anecdotal evidence to say I think the Lexar claims are believable.

The CF cards come in sizes ranging from 16 to 128GB. The SD cards come in sizes ranging from 16 to 64GB. The cards I tested were 32GB.

There is some fine print you should know about. The speeds are guaranteed when using the Lexar Professional USB 3.0 Dual-Slot Reader which offers up to 500MB/s transfer speeds. Not all computers have or support USB 3.0. Additionally, not all cameras are equipped to take advantage of UDMA7 (CF) or UHS-I (SD) so check with your camera manufacturer to make sure that your camera works at these speeds. In some cases, the cards will work fine, but not offer the promised speed improvements. In more critical cases, such as SDXC (which Lexar also offers in this line but which I did not test) there are many cameras that do NOT support SDXC and use of an SDXC card in a non-supported device may result in data loss. ALWAYS test a new card in your own camera before using it for anything critical.

I tested both the SD and the CF cards for several hours, running LOTS of video to and from both. These cards are designed for fast video transfer rates and those of you shooting video on your DSLR will be very impressed with the high transfer speeds. Everything worked as advertised and while I can’t vouch for these particular cards’ reliability since they are so new, I can say that no Lexar card has ever failed me.

The cards come with a limited lifetime warranty and Lexar offers free tech support. For more information visit Lexar.com.

Highly Recommended.
