Best workstation for DVR using multi-input PCI video capture cards.
Posted on 2004-10-17
I have found "old" answers to similar questions...but I'm looking for some updated answers.
I would like to assemble a new (and stable) machine for digital video recording using multi-input PCI capture cards.
My current computer has an Asus P4P800 Deluxe MB, P-4 3ghz CPU, one gig of ram, 4 HDs. Two of the drives are SATA-raid-0 for storage and two ATA-133 raid-1 for the OS (Win-XP Pro) and programs. All of the software and drivers are current (they have the most recent updates). This setup has proven to be a very flaky combo.
The SATA raid drive(s) are a real pain. Every few weeks they have a write error and I lose a lot of data. My best quess, after reading a lot articles, is that the PCI bus is overloaded by the capture cards and may be part of the problem with the onboard SATA-RAID controller.
Since the software and capture cards support dual CPUs, I intend to ditch this system and replace it with either a dual P-4 or Xeon system and an Ultra-SCSI raid controler and hard drive setup. But after looking and reading all I could find during the past few weeks, I can't find any consistent answer/opinion as to what the ultimate system is for this application.
BTW, my software/dirver combo only works under XP-Pro 32-bit. I mention this because I have an AMD-64 bit machine running WinXP Pro x64 edition, but there are no divers avaiable for my capture cards, so these machines are not, yet, a choice.
Of course, cost is a consideration up to a point. Like, I would keep the parts price under $4,000.00. I've assembled over 50 machines in the past few years, so assembly labor is not an issue.
