Longsys, under the Lexar brand name, has announced the Lexar Professional 633x SDXC UHS-I card with 1TB of storage. The Class 10 UHS-I card has a theoretical maximum read speed up to 95MB/s and write speed up to 70MB/s, but it's only guaranteed a sustained write speed of 30MB/s as noted by the V30/U3 rating.
This means the write speeds might peak at 70MB/s, but the card certainly can't sustain them, otherwise it'd be labelled as a V60 card.
The card, which is also available in sizes down to 16GB, is capable of operating from 0° to 70° C (32° to 158°F) and being stored from -25° to 85° C (-13° to 185°F) in humidity levels between 5 and 95 percent. Each card comes with a limited lifetime warranty.
The 1TB Lexar Professional 633x SDXC UHS-I card is available now and retails for $499. 99.
