ProGrade Digital Inc. announced that it will change the sustained write speed message for CFexpress 4.0 Type B GOLD 512GB, 1TB, 2TB and CFexpress Type B COBALT 1.3TB 4 products released in 2023. In line with this change, each label design will be changed sequentially from mid-March 2024.
There are no design changes to the product itself, only the sustained write speed message and label design, so the maximum read speed of 3400MB/s and maximum write speed of 3000MB/s remain unchanged. Products currently on sale will continue to be sold with the original label design.

■ Reason for change
In consideration of the current usage environment of general PCs, we have changed the speed measurement method to specify a sustained write speed that is closer to actual usage conditions.
