The SanDisk 64GB Extreme CF memory card - UDMA 60MB/s 400x is a mid-range option designed for photographers who want a balance between performance, storage capacity, and affordability. Here's a breakdown of its key features:
SanDisk Extreme: Belongs to SanDisk's mid-to-high-range series, offering better performance compared to their standard lines.
64GB Storage: Provides ample space for a significant number of high-resolution photos and several minutes of high-bitrate videos.
CF (CompactFlash): Refers to the physical format of the card. CF cards are larger than the more common SD cards, historically used in professional DSLR cameras. Ensure your camera uses CF cards before purchasing.
Speed:
Up to 60MB/s Read Speed: This is the maximum speed at which data can be transferred from the card to your computer. 60MB/s is a decent read speed, allowing for acceptable transfer times for your photos and videos.
400x Speed: This is an older way of expressing read speed. It multiplies the base clock rate of a CD (150KB/s) by a factor (400x in this case). While outdated, it translates to a read speed around 60MB/s, matching the previous specification. It's recommended to focus on the MB/s value for a clearer understanding of speed.
UDMA 6: Stands for Ultra Direct Memory Access 6. It's an interface that defines how data is transferred between the card and the camera. UDMA 6 supports the moderate read and write speeds of this card.
