Have there been any results or comparisons between Mtron SSDs vs xServeRAID?

Hi,
I have tested also with HDV, DCPROHD, H264 and ProRes codecs... and we only had good performance with one layer.
We tryed to sync two plays from the same clip (and two different clips) and both are on sync.. but on the Catalyst Display, Video one is at 25fps and video 2 is at 11 fps..
I know that Richard always recomends DV, but I prefer Photo-JPEG because you can control the compression and the quality is much better since it's a true progressive codec.. so everything but video looks crisper and with better color range.
Anyway in HD, you cannot use DV (unless you force settings out of standards), so I guess I will continue with Photo-JPEG.
"OPPSSS... I skyped by accident the posts about Apple Intermediate Codec, I will check it out!"
But a good option to optimize the performance will be to define two different Content Drives/Volumes as Catalyst Libraries.
In my case I have a SCSI volume and a Raid Volume of 3 Raptors.
It will be nice to be able to have some videos on the SCSI and the other layers on the RAID..
It's possible to define Catalyst Libraries at different volumes?
Thanks!

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!
If the Costumer is picky... he will notice the DVCPRO HD Compression... ProRes visually is like Uncompressed so it's a good choice.
but..
ProRes it takes a lot of computer resources to uncompress, specially over the Graphics board.. on the Decklinks are sigthly better.
So what you will gain on bandwith probably will affect the overall performance of the system.
ProRes is a resoure eater codec!
Apple intermediate codec works best - far better than anything else.
You need to look at MTRON SSD for HD playback - works so much better than anything else
I agree with you. I have yet to buy an xServeRAID. I do however have several machines with 32Gb and 64Gb Mtrons in them and they work fine. I do have a few seek issues with the Mtron and Catalyst. I end up crashing Catalyst. When I can duplicate the issue I will report it.
Now that I have SSDs, many of the multi-projector edge blending projects I am doing are getting HD content. I have started taking all of my stock HD content (Motion Loops, Artbeats, Digital Juice) and converting it to Apple Intermediate Codec @ 1920x1080 and 1280x720.
The problem is, a dozen or so stock content libraries eats through a 64Gb disk fast. At least with an xServe Raid I would have more storage space for some of these permanent installs I'm working on.
