Sandisk 64GB Extreme CF memory card - 120MB/s 800x UDMA 7

The SanDisk 64GB Extreme CF memory card - 120MB/s 800x UDMA 7 is a high-performance CompactFlash (CF) card designed for professional photographers who need a blend of storage capacity, speed, and durability. Here's a breakdown of its key features:

SanDisk Extreme: Belongs to SanDisk's mid-to-high-range series, offering better performance and reliability compared to their standard lines.

64GB Storage: This capacity provides ample space for a large number of high-resolution photos and several minutes of high-bitrate 4K videos.

CF (CompactFlash): Refers to the physical format of the card. CF cards are larger than the more common SD cards, but were historically used in professional DSLR cameras. Ensure your camera uses CF cards before purchasing.

Speed:

Up to 120MB/s Read Speed: This is the maximum speed at which data can be transferred from the card to your computer. 120MB/s is a very fast read speed, allowing for quick transfer of large files after shoots.

800x Speed: This is another way of expressing read speed, using a multiplier of the base clock rate of a CD (150KB/s). In this case, 800x translates to a read speed around 120MB/s, which matches the previous specification. It's an older way of representing speed and not as informative as MB/s.

UDMA 7: Stands for Ultra Direct Memory Access 7. It's an interface that defines how data is transferred between the card and the camera. UDMA 7 is a high-performance standard that supports the fast read and write speeds of this card.
