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.
Running the Kingston through CDM, we found the card was quite capable of reaching the 94 MB/s read as set forth by marketing. We also met marketing specifications with write performance at 85 MB/s.
Price/Performance puts the Kingston in the top three SD cards we have tested.
For those of you in the market, getting ready to, or already have upgraded your camera equipment to 4K capabilities, the Kingston SDA3 is certainly a great choice. Build quality is about as good as it can get with memory cards.
Performance of the SDA3 was quite good. In read testing, we were able to touch 95 MB/s, while write testing came in at 85 MB/s, more than doubling the standard for UHS I Class 3.
