Lexar has officially launched its highly anticipated CFexpress 4.0 Type B Diamond card, offering unparalleled speed and performance for professional photographers and videographers. After debuting at NAB 2024 and IFA 2024, this 1TB card is now available, promising up to 3,700 MB/s read speeds and 3,400 MB/s write speeds—making it one of the fastest cards on the market. However, while these speeds are impressive, they can only be fully utilized with a compatible CFexpress 4.0 device, as no current camera supports CFexpress 4.0 technology yet.
Compared to its competition, the CFexpress 4.0 Type B Diamond card offers a mid-range balance. For example, Wise offers peak read/write speeds of 3,400 and 2,600 MB/s, while Nextorage’s cards hit 3,900 and 3,600 MB/s, respectively. Lexar’s card is notable for its durability and reliability, coming with eight-point protection against extreme conditions such as temperature, dust, vibration, and shock. Furthermore, the card is VPG400 certified, ensuring it can handle cinema-quality 8K RAW video capture without any hitches, making it a top choice for high-resolution workflows.
A Closer Look at Capacity and Pricing
One of the standout aspects of Lexar’s card is its capacity. Currently, the Diamond series only comes in a 1TB version, while other brands offer more variety, with larger and smaller capacity options. Despite its price point around 1€ per gigabyte it remains a compelling option for those seeking cutting-edge performance.
