Currently we're using these Samsung Pro's in three different bodies in my house.Getting ready to purchase the 5300 and I am looking at all the options for SD cards.
What SD cards do you use for your D5300?
I was in Tesco the other day and noticed a good 40MB/s 32GB SD Card. I've only ever used a 20MB/s 16GB card, and never really had an issue with this, but as my skill develops, so does my need for better performing kit.
As Dxer says, it all depends on your type of shooting. If you're going to go on Continuous H mode, shooting 5fps, then you'll benefit from the faster cards. Single shots, you won't notice any performance issues with a 40MB/s card.
