HD Playback on Catalyst

[jjrecort]

the problem is that SATA discs have very poor random access data rates - sure they can do 150MB/s or more in a RAID config- but that is for 1 file - read sequentially.
catalyst does not read 1 file sequentially. It reads 1 file for each and every layer. In a random and unpredictable manner.
And SATA raids can actually perform worse with catalyst than a single

But What about WD RAPTORS..are SATA but with the same specs of the SCSI.. 10.000 rpm and

- Read Seek Time 4.6 ms
- Write Seek Time 5.2 ms (average)
- Track-To-Track Seek Time 0.4 ms (average)

The problem is when we have to move HD files.. we need both.. high output and high access speed!
