Working With Scratch Disks and Hard Disk Drives
By default, Final Cut Express HD uses the hard disk on which the application is installed
as your scratch disk to store captured and render files. Ideally, you should use a hard
disk other than your main system disk as your scratch disk. Depending on how much
space you need for your media, you can have up to 12 scratch disks in your
Final Cut Express HD editing system.
Important: If you have multiple hard disks and partitions, make sure they do not have
similar names, or you could encounter problems during capture. For more information,
see “
Using Multiple Hard Disks ” on page 51.
Data Rates and Storage Devices
The data rate of the video you capture depends on the format of the source video and
the codec you use for capture. The data rate for DV and HDV is 3.6 MB/sec.: Whatever
disk drive technology you decide to use, your storage disk’s sustained transfer speed
must be fast enough to keep up with the data rate.
