Lexar 64GB 2000X SDXC Digital Camera Storage Card
How fast do the fastest digital camera storage cards go? Your author reviews and uses many brands of cameras; some camera use CompactFlash and some use SDXC and some have dual slots, one of each kind.
For the latest cameras producing big files, a fast SDXC card can make a noticeable difference in responsiveness, assuming the camera supports the latest protocols (older cameras not likely to benefit).
The most reliable and fastest CompactFlash card I’ve used is the Toshiba Exceria Pro—not one glitch ever.
I hugely prefer high-capacity cards (64GB) because in the field there is no need to erase them, thus they are an additional backup over and above downloading the day’s shoot (and backing that up too). Aside from cost, I’d be buying 128GB or larger cards for that resason, but for now 64GB serves me amply for most of my trips (not filling up).
The graph below from DiskTester data used the supplied USB3 reader with the Lexar 2000X 64GB SDXC card. It shows that the card is capable of sustaining very high write speeds, and even higher read speeds (a very fast hard drive might do 220 MB/sec).
