The Lexar Gold Series CFexpress Type B cards feature a PCIe Gen3x2 interface which plays a part in enabling the fast data transfer speeds. Maximum read speed is a healthy 1900MB/s, and peak write speed is almost as impressive at 1500MB/s. Lexar also says its Gold Type B card can sustain a 1300MB/s write speed, which is great if you plan on using the card to record 4K, 6K or 8K video, where prolonged write speed matters more than peak speed bursts.
Lexar quotes an operating temperature range of -10°C to 70°C and a storage range of -25°C to 85°C for these cards, which should be more than enough for all but the chilliest conditions.
