About the Delkin Pro 4GB UDMA 6 CF

High Performance Photography...

Delkin's CompactFlash Pro UDMA enabled cards deliver industry-leading read/writespeeds with a minimum sustained transfer speed of 305x (45MB/sec).

The enhanced camera-to-card and card-to-computer transfer times considerably improve workflow for any pro photographer in the field.

Delkin's CompactFlash Pro UDMA cards when used with the Delkin's line of Pro readers and adapters, dramatically reduces the time needed to download digital image files to a computer.

The difference may be crucial for those working in the field with battery operated laptops, and particularly important for pros working in news media, wedding or event photography.

Certainly any photographer working with larger RAW files will experience a great benefit in faster transferspeeds in the camera and computer.

What is UDMA (Ultra Direct Memory Access)?

The advantages of UDMA over previous transfer modes are the use of double edge clocking, that is transferring data on both the rising and falling edge of the clock thereby doubling the data transfer rate per clock and increased reliability by the use of cyclical redundancy checking (CRC) for data transferred over the bus.

Basically, this new technology facilitates data transfer; dramatically increasing transfer speeds, allowing for a more streamlined workflow process.

It's important to note that UDMA technology is ONLY utilized when used in combination with UDMA enabled devices, such as Delkin's FireWire 400/800 reader,the ExpressCard CF adapter, or CardBus32 UDMA adapter.
