1. Battle of the 1066x 128GB CF cards
2. Meet the Lexar Professional 1066x 128GB CF card
3. Meet the Toshiba Exceria Pro C501 128GB CF card
5. Final thoughts
CompactFlash (CF), a flash memory mass storage device used mainly in professional devices and high end consumer devices such as digital cameras, is possibly the most successful of the early memory card formats.
Today we are testing two 128GB CompactFlash cards that offer high-speed performance by leveraging the UDMA 7 technology to deliver a read transfer speed up to 1066x (160MB/s): The Lexar Professional 1066x CompactFlash and the Toshiba EXCERIA PRO - C501.
UDMA 7, which stands for Ultra Direct Mode Access 7, is the latest transfer mode under the UDMA interface. UDMA 7 allows a maximum transfer rate of up to 167MB/sec. This can be compared to the previous UDMA mode, UDMA 6, which allowed transfer rates of up to 133MB/sec.
The cards both conform to the CF 6 Specification and can be used with existing CF and CF UDMA devices (backwards compatible).
Both cards lets you capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video. And you’ll power through post-production with high-speed card-to-computer file transfer, when paired with a UDMA 7-enabled reader.
