The great thing about CFexpress cards is their consistency. While there’s a good choice of cards out there, the performance-to-cost ratio is pretty evenly matched across the board. The Lexar Professional CFexpress Type B Card SILVER Series is a mid-range card; however, its performance is more than enough for the vast majority of cameras out there at present.
Lexar states a transfer rate of 1750MB/s with a sustained transfer rate of 1200MB/s. In the Canon EOS R5 C that was used to test the card, these speeds were more than enough, and the camera recorded at its highest internal settings without a glitch.
In the benchmark tests, again, the card performed well, with the results showing close to the maximum transfer rates and actually bettering the values quoted by Lexar.
At 1TB, this is a high-capacity card, and as such, the cost is quite steep; however, it’s by no means the most expensive, with the Gold range adding quite a bit to the initial outlay if you do want to take that step up in speed and capacity. However, at present, that extra cost really doesn’t seem worth it when you have a card that puts in a performance that will keep up with the latest crop of cameras. For the money, this is the card you want if you’re shooting 4K log footage at high-quality settings.
What is the Lexar Professional CFexpress Type B Card SILVER Series?
The Lexar Professional CFexpress Type B Card SILVER Series is a CFexpress Type-B card with a large 1TB capacity, although it is available in smaller capacities as well.
The Silver card is a mid-range offering, although the speed of the offer here for both reading and writing will be sufficient for almost every camera currently on the market.
As the card follows the usual guidelines for CFexpress, aside from the label, there is little else to differentiate this card from another, and it’s only when inserted into the camera that the real quality of the card’s performance can be seen.
