  1. Redundancy isn't a major issue, anything I really need to keep I put on my server, which runs U160 RAID5 and has a 7-slot SDLT library to back it up. As for the RAID0+1 idea, that came from a friend of mine who works relatively high up in GM's IT department, as a consultant. He had said that as the number of spindles increases, so does throughput. Then again, I think he was speaking of high-end SAN implementations, not desktops. Also, space isn't too much of a concern, even 70 minutes from 8 tracks of 24-bit/192KHz audio is only 36.8GB. I'm a 2K systems administrator by day, I know better than to keep my data on a desktop. I'd rather be able to run tons of disk-intensive software at once rather than have 2TB of storage on a desktop. I honestly don't know what I'd do with all that space, even if I got an HDTV tuner and started recording all my favorite shows uncompressed. Lastly, a lot of the on-board SATA RAID controllers are coming with 4 ports now. I had originally looked at getting a 3Ware 8006-2LP controller and throwing it in a 64-bit PCI slot, but I looked at some side-by-side comparisons with the ICH6R, and they were pretty close. I'm not sure, but I believe the ICH6R uses the PCI Express bus, which would explain that.
  2. But which config? The Matrix RAID with two Raptors, or the RAID0+1 with 4 7200RPM disks?
  3. I read the article on the RAID on the desktop craze, and largely I agree, but now I'm a bit lost in what exactly I should use as a primary disk in an entry-level A/V workstation. I had originally thought that my best bet would be to use Intel's new "Matrix RAID" config to make myself a 16GB RAID0 volume for OS/Apps, and JBOD out the rest of the space on two Raptors for writing short recordings to. However, this appears to be a waste of money for the performance increase (even though the graphs in the "seductive acronyms" article appears to indicate that going from a single disk to 2-disk RAID0 ups the high-end drivemark from 580 to about 650). Now, I'm torn between two options: 1. Use the ICH6R SATA controller to hook up a single Raptor 74GB, or the above with 2 Raptors. 2. Buy the Seagate ST373405FC that a friend can't return from his company's failed Fibre Channel enclosure, one of these, and a QLogic QLA2200 for $50 on EBay. 3. Buy 4 Seagate ST380817AS, hook them up to a secondary SATA RAID controller, and run them in RAID0+1. Fibre Channel on the desktop sounds as absurd to me as RAID0 sounds to the reviewers. All four options are in my price range, and actually the FC is cheapest, considering I can get the disc for $100, the HBA for $50 on EBay, and the 9-pin to SCA adapter for $20. Theoretically, I could even use the money I save to buy a mobo with 64bit/66MHz PCI slots. It looks to me like the U160 version of the FC drive in question scored way low as compared to the Raptor, however. Here's my prospective parts list, if it makes much of a difference: Processor- 3.2GHz Prescott LGA775 Mobo- Supermicro P8SAA Memory- 2xCrucial 512MB DDR2-533 Hard disk(s) - ??? Optical drive- Teac DVW58GA Video- Matrox G550 PCI Sound- M-Audio Revolution 5.1 Mouse- Logitech MX900 Case- Cooler Master Centurion 4 PSU- Antec True380 $61 Newegg <-might go with a bigger unit if I run multiple disks So, o oracles of storage technology, which way should I go?
