Matrox RT.X100 Xtreme Pro data transfer rate requirements
To be compatible with the dual-stream operation of Matrox RT.X100 Xtreme Pro, the storage device you use must sustain a data transfer rate of at least 12 MB/sec.
Note Our tests have shown that 1394 hard drives are not capable of sustaining the data transfer rates that are needed for video editing with RT.X100 Xtreme Pro.
General storage considerations
Storage plays a vital role in the overall performance of your Matrox RT.X100 Xtreme Pro system. Without adequate storage for your audio and video clips, your system will not work properly.
Certain issues, such as what to store on your A/V drives, use of the NTFS file system, and disk defragmentation, are important to the use of both EIDE and SCSI storage devices with Matrox RT.X100 Xtreme Pro.
Dedicated Audio/Video (A/V) and export drives
To use Matrox RT.X100 Xtreme Pro, you must store your audio, video, and graphics files on an A/V drive reserved solely for this purpose. If you want to perform realtime exports to disk, you'll also need an additional drive dedicated to perform exports. Windows frequently needs to access your system drive for various reasons, so attempting to store your audio/video files on your system drive will provide unacceptable performance.
Unless you're using a Serial ATA (SATA) drive, you'll need an additional drive dedicated to perform realtime exports to disk. Due to the advanced transfer rates of Serial ATA (SATA) drives, a single SATA drive can be used for both the A/V and export drives.
Your system's virtual memory paging (swap) file must be stored on your system drive and not on your A/V drive. By default, Windows stores this file on your system drive. For information on how to configure your system's virtual memory, see your Windows documentation.
Note Do not create multiple partitions on your A/V drives. Doing so can reduce performance leading to dropped frames in your projects. Make sure you have only one partition per A/V drive.
Planning your connections
In addition to most SCSI devices, almost all recent EIDE storage devices are able to meet the data throughput requirements of your Matrox RT.X100 Xtreme Pro system. You can have only two EIDE devices on each of the two controller connections found in most PCs. When you connect your EIDE devices, you must connect your A/V drive and your dedicated export drive to separate controllers.
The following diagram provides a typical EIDE device configuration for your system:
Using ATA RAID controllers
If you are using an ATA RAID controller to create a striped volume consisting of two or more drives, the volume can be used for both the A/V and export drives. Please refer to your RAID controller's documentation for information on how to create and configure striped volumes.
Important If you are using an ATA/133 RAID controller, make sure that you stripe your EIDE drives using Windows Disk Management. Failure to do so may result in erratic behavior of your RT.X system.
