Lexar offers a 2-pack of the 64GB CompactFlash Memory Card Professional 1000x. Each card features maximum read and write speeds of 150MB/s and 145MB/s, respectively. UDMA (Ultra Direct Memory Access) 7 technology gives them a 1000x speed rating, allowing for faster, smoother high-resolution photo and HD video capture, as well as quicker transfers to a computer. The cards will achieve their fastest transfer rates with UDMA-compatible host devices, though they will also work with CF-compatible devices that don't support UDMA.

When paired with a UDMA 7 enabled reader (not included), the cards offer fast file transfer to computer to accelerate your workflow. Image Rescue 4 software, available via free download, lets you recover lost or accidentally deleted photo and video files--even if the cards have been corrupted. Additionally, your investment is backed by a limited lifetime warranty and free professional tech support.
