Hi, I'm sorta' new at building computers, and I have a newbie question.
I'll be building a professional computer workstation that'll mainly be used for video editing, compositing, and capturing. I'd like to set up a 4 500GB 7200RPM HDD RAID 10 system. This RAID will be used to capture video from a Blackmagic Design UltraStudio SDI capture device and as a scratch disc for video editing and compositing applications such as Avid Media Composer, Adobe Premiere Pro CS6, Boris Red, and Adobe After Effects CS6. If I understand RAID 10 correctly, I'll be getting 1TB of usable storage with data protection, and I'll need a physical RAID controller. I've observed that one of the most significant factors that raises the price of RAID controllers is how much on-board memory that they have.
My Question:
Do I really need an expensive RAID controller with on-board memory for my specific workstation applications?
If I understand...the RAM that's on those controllers is only for storing data while the read/write heads on the HDDs move into position. This seems like it would definitely offer an advantage to someone who's using the RAID as a general storage device or an NAS server, because, in those cases, the RAID would likely be full of data that would be accessed more randomly.... However, for capturing video or for scratch disc applications, I don't know if I would experience an increased write speed due to that RAM. I'm thinking this way because, as long as the drives in the RAID are relatively defragmented, the write speed should remain high and constant after the first few seconds of capture because the write heads are not moving significantly...right?
If I start to capture video from my capture device, the write heads should move into position and begin to write the data in a linear fashion--not needing to move to different parts of the discs in a random way...right?
Please let me know what you think.
All advice is appreciated.
Thanks.
