What I’m finding is they work great.
I have used a Transcend 16GB Class 10 SDHC a lot in the last few months and they have worked perfectly. I take a lot of RAW image files and jpgs without problems.
I would recommend you go with the Class 10 version especially if you take a lot of video. I have captured a lot of HD video on my Canon 60D onto these cards with zero dropped frames. Not bad at all for a fairly budget option.
In my upcoming DSLR training course I mention the importance of extra memory cards for a number of scenarios.
Amazon.com just lowered the price of the Transcend 16GB Class 10 SDHC to $27.20. At that price it’s a no-brainer to have the peace of mind of all that extra space.
In my free DSLR buyer’s guide I mention that for professional reliability I always reach for Sandisk Extreme memory but lately I haven’t been able to fault Transcend.
If you have had any experiences to share with Transcend Memory I’d like to hear your story below.
