For years, Lexar Media has always supplied the fastest speed-rated CompactFlash (CF) cards to professional photographers meeting their most demanding needs for performance and reliability.
With the introduction of Write Acceleration (WA) technology, Lexar Media continues to innovate in high-performance digital media.
Write Acceleration technology is unique in that it is enabled by two components; one resides in the camera firmware and the other in the CF card firmware.
When a WA enabled camera detects a WA enabled card the two are able to transfer data with less overhead, improving the throughput and taking greater advantage of the card's 24x (3.6 MB/s) write speed.
The ultimate write performance of any CF card in a high-resolution professional SLR camera is affected by several factors.
The camera's image processing engine, the amount of processing a camera performs (e.g.
RAW vs TIFF) resolution, file size, internal buffer size and CF card write speed are just a few.
Lexar's high-speed Professional CompactFlash cards with Write Acceleration Technology offer both high speed and high throughput for the types of large data files today's professional cameras can produce.
When the camera is powered on, it automatically detects the card information and supported features.
Non-WA cameras will not check for the Write Acceleration technology feature of the card, and the Lexar Media 32x-speed Professional CompactFlash card with Write Acceleration technology will perform just like a regular 32x-speed card without Write Acceleration technology.
Digital cameras and media designed for speed Write Acceleration Technology (WA) allows digital cameras and CompactFlash cards to work together perfectly to pass and store images more quickly and achieve image-write speeds never before possible.
Speed rated at 32x (4.8 MB/s) Improved write performance in WA enabled cameras by up to 23% vs standard 32x pro card.

Shooting in TIFF mode, the best quality mode in many high-end cameras, will reduce the number of images listed above significantly (approximately one-sixth).
