Storage recommendations

This section provides you with some important information to help you choose the right storage device to use with your RT2500 product.

Choose from the following two categories:

RT2500 data transfer rate requirements

To be compatible with the dual stream operation of the RT2500, a storage device you use has to sustain at least 12 MB/sec data transfer rate.


The hard disk manufacturers have done a significant step forward over the last few years. In the past, it was extremely difficult to name any hard disk that was capable of sustaining the transfer rate necessary to capture, playback, or edit in a smooth trouble-free manner. However, we found out that all hard disks manufactured within the last year should be acceptable, as long as they have a rotational speed of at least 5400 RPM.

IEEE-1394 is a new technology that has greatly expanded in the last year. Also referred to as Firewire or i.Link, it is an interface that enables modern consumer electronic devices to communicate with computer equipment in a fast and easy way. High data transfer rates and possibility of connecting multiple devices make IEEE-1394 especially suitable for multimedia components, video in particular. The new DV cameras using 1394 technology to integrate with the computer is an example. It can also be used for connecting other bandwidth-intensive hardware devices, including hard drives. However, our tests have shown that 1394 hard drives are not capable of sustaining the data transfer rates that are needed for video editing with RT2500.

Although in most cases one hard drive used for both audio and video is enough to achieve a sufficient data transfer rate, you can boost your system's capability by adding an additional hard drive dedicated for audio and graphic files only. Having a designated hard drive for each area of editing results in enhanced performance, as data throughput is spread over multiple drives as opposed to one hard drive performing all operations alone. Additionally, instead of a single-drive solution, you can acquire an IDE RAID adapter card. With this type of setup, you can combine two or more IDE drives to create one larger logical A/V drive. As a result, you achieve significantly increased read and write times compared to a single IDE drive.

Note : To avoid conflicts when adding IDE RAID controllers to the system, make certain that the resources used by this device and the RT2500 are not shared. To do this, make sure that you are using the latest device drivers for the IDE RAID controller. You may also have to move the RAID controller to a different PCI slot so that the system can assign different resources to it.
