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!

raptors do not work as well as scsi.

Use MTRON SSD. works much better
