Note: Due to overhead considerations, such as opening and closing files and updating the

directory and FAT32 table, the maximum allowable bit-rate must always fall below the

theoretical write/read speed of a given Compact Flash card.

40. How fast can I transfer the files to my local hard-drive?

Depending on the type of CF card and the speed of your hard-drive and PC/MAC, you

can transfer 50/100 Mbps files at rates up to 8X/4X times faster than real-time. So one-

hour of footage shot at 50 Mbps can be transferred in about 7.5 minutes; while the same

footage shot at 100 Mbps requires about 15 minutes (since the file size is doubled).

The above assumes that a PhotoFast 533X CF card, a SanDisk Express 34 PCIe CF

Reader and a fast (SATA-II) hard-drive. Transfer times will be much longer using a USB

2.0 card reader and moderately slower with a Firewire-800 reader.

You should also consider the use of the portable Nexto drive for backup and offloading of

the CF cards. (See below for more details).

41. How fast to import clips into an NLE?

Almost instantaneously; since nanoFlash supports the native QT and MXF files used by

most NLEs, you can play/edit the footage directly off the CF card without transcode or re-

wrap of the data.
