Memory cards have come a long way in the last year. The SD format has seen a few speed increases and subsequently added two new classes. The first is the new U3, or UHS I Class 3, which enhances the write speeds of the memory cards to include 4K capabilities, while the second is a bigger jump to the new UHS II standard.
In the lab today, we have the Kingston 64GB UHS I Speed Class 3 card. Marketing specifications for this card note 90 MB/s read speeds and 80 MB/s write speeds, perfect for shooting 4K video.
MSRP of the 64GB Kingston SDXC UHS I Speed Class 3 memory card is set at $159.99 with a lifetime warranty.
The front of the memory card houses the branding and capacity information. Note the new logo for the UHS I Class 3 standard.
Physically, UHS I Class 3 cards embody the same dimensions as previous cards.
The Kingston SDA3/64GB is factory formatted with the exFAT file system. The usable capacity after formatting is 59.7GB.
