Lexar Professional 1000x 32GB SDHC UHS-II Card
If SanDisk is the most respected memory card maker currently, then Lexar has to be a close second. Lexar incorporates similarly strict quality-control measures at their factory and the result is a product line that many professionals trust with their irreplaceable data. Lexar is a consumer brand of memory giant Micron, one of the world's largest memory suppliers, so you can be assured that the company will be around to back that lifetime warranty though you will never need them to.
The latest iteration of the venerable Professional line, the Lexar Professional 2000X SDHC UHS-II (U3) is a real data reading burner, rated at an industry-leading 300MB/s. For writes, Lexar uses what is probably the more important of the read specs which is minimum data write speed. In this case, the minimum write speed is 30MB/s which is plenty fast for 4K video recorders and beyond.
Since this card is so fast (and chances are you don't have a reader that can exploit those stratospheric read speeds) Lexar include a speedy UHS-II card reader with each Professional 2000X memory card. It's a very practical bonus and one that you can use for any card, not just the Lexar. And since it's little more than a USB dongle, throw it in your bag so you’re never without a convenient way to download your data.
Like other products on this list, the Lexas Professional 2000X comes with access to data recovery software, dubbed the very to-the-point Image Rescue Software. So long as the data hasn't been written over, Image Rescue can retrieve files you may have accidentally deleted.
I’ve personally used many Lexar Professional cards and not a single one has ever let me down. But you don't have to take just my word for it, the internet is replete with testimonials expounding the virtues of Lexar's products. They really do make a reliable product and you shouldn't think twice about trusting your data on them.
