    VGA or S-Video?

    VGA is usually a lot better than S-video because it is RGB. To get the best picure with analog video, use a cable with the shortest possible length. If you go above 10 meters, you will likely need a high quality cable not to se artifacts.
  2. It does work if you manage to get the latest drivers etc. I run a Raptor and several Samsungs on ICH9R on an ASUS motherboard. It wouldn't even boot in RAID or AHCI mode. I tried all workarounds I could find but in the end, the only thing that worked was to get the latest drivers from Intel. However, they wouldn't install unless the system was in AHCI mode, in which it wouldn't boot. ... Luckily, my MB has a Jmicron chipset used for the e-SATA ports. So, I got a e-SATA > SATA adapter cable, put the system in AHCI mode, booted from JMicron, updated Intel drivers and ... then it worked flawlessly. Now I boot from my single RAPTOR on ICH9R, the system is in RAID mode, I run both RAID0 and RAID1 in Matrix with my Samsungs and performance is good.
  3. Here is the sequential throughput for the Matrix raid configuration i mentioned earlier in the thread. The drives are two Samsung 160 GB (1 platter). Only the first 100 GB are used from each drive. Raptor 74 GB is included for reference. Motherboard is ASUS P5K-E WiFi, which was somewhat a struggle since XP bluescreened when trying to boot in SATA-mode. Had to boot from the JMicron chip with eSATA in order to be able to update ICH9R drivers. This graph is with a 16KB raid-stripe, which seems to be the fastest for me.
  4. I just built a video editing system myself. I went with the following setup: I use a single WD Raptor 74 GB as a system drive for OS and applications. The drive is quick and is supposed to be of higher quality than mainstream 7200 rpm drives (5 years warranty). The 74 GB Raptor has only one platter, which is safer and more quiet/energy efficient than the 150 GB Raptor, which has two platters. RAID0 was not an option for the system drive because of safety reasons. In the long run, I plan to replace the Raptor with SSD. As a "source disk" during video editing, I use two Samsung 160 GB in Matrix RAID 0 configuration. I use only the first half of each disk to squeeze out maximum sequential read performance. The disks are single platter for maximum safety and minimum noise and heat. The remaining half of the disks are Matrixed into RAID1. This partition will be used for passive backup of important information and software (not video). The RAID 0 partition will be used only during the editing process when I need maximum throughput. I could have gone with larger drives at very little extra expense but since I don't want to store things permanently on RAID 0, it wasn't worth the extra noise, heat and unreliability. As "destination disk" during video editing, I use a single 500 GB Samsung. This disk has good sequential write performance and low noise and heat output. The output part of the video editing workflow is a lot less demanding than the input part. That's why I don't bother with RAID 0 here. Backup and long term storage is going to external disks on e-SATA, firewire and USB. I'm a noise-hater so I'm still experimenting with different mounting methods and cooling solutions for the disks. I currently have the Raptor and the 500 GB in Scythe enclosures and I'm going to experiment with suspension. My current installation results in slight overheating but this is not unexpected since the only fan in the box is the one in the PSU.

    WD360ADFD versus WD1500ADFD

    I'm also contemplating the 36 GB Raptor for my next build. I'm thinking two of these would be much faster than one 150 GB if utilized correctly. The 36 GB is a single platter version and they normally have a little better seek characteristics, lower noise and heat but slower STR. I have never seen any benchmarks on the new 36 GB Raptor though. Anyone ?
  6. The write caching is probably turned off for the disks. Do a "format -e" and go into the cache settings to turn it on ...
  7. Sorry for changing the subject but what's wrong with EMC ? I see people specifying EMC hardware for SAN installations where I work so any pointers to information showing bad things about them would be interesting...

    SientPCReview is your friend. You could try a good cooling and silencing drive enclosure. This is a hot topic on the SPCR forum for silent storage. Silent storage forum Here is a review and a thread: HD enclosure review
  9. The obvious solution is to not handle everything at once. Unless the material is completely shuffled, there is little reason to transfer everything to hard disk at once. As long as you still have everything on tape, you will not loose data in case of hardware failure. Processed data is more expensive and you may want to invest in redundancy for material that has been edited or selected from the raw data. You could also do some selection of which data to save inline with the capture process. If you have a workflow that filters away unwanted data as it comes in, the storage requirement drops dramatically. Depending on where you live, 250 - 320 GB disks are cheapest per GB. However, the 400 MB variety is not far behind and it will be more convenient with larger and fewer disks. The Samsung 400 MB drives seem pretty ideal for video storage (high sequential throughput, low price, low noise and low power). Reliability is almost impossible to test in a review and newer drives will have unknown failure rates. A RAID1 setup for critical data will be your best bet if you are nervous.
  10. I used to go down that route, trying to get decent sound from a computer directy into the hifi system. After failing with a number of solutions (not very restricted by budget), I made the best decision yet - I got a Squeezebox. You will find lots of information online about this product if you care to research. The Audiophile community has slowly and unwillingly had to start realizing that the Squeezebox sounds equal to or better than dedicated transports from well known brands, costing more than 10 times as much. You will still need a computer in one form or another to store your music but you don't have to care much about the distance since you will use wired or wireless network. If you can affort $250 for this kind of convenience and sound quality, do yourself a big favour. And btw. Focus on room acoustics rather than cables if you are interested in real improvements.

    Best SATA drive for Video Editing

    The Samsung 250 GB would be a good choice. It has a very high sequential transfer rate and very low noise and heat output. Don't forget to check out all previous threads on video editing storage in this forum. Unless you already have a couple of drives in your system, you will not want to RAID the drives.
  12. X-bit labs has performed very extensive hard disk tests (such as this one) that may give you some clues. This is all very complex and dependent on many things.

    Video editing workstation

    This has been discussed a few times on the forum already and you may find some interesting information with a little search... Depending on the video software, multiple CPUs (or dual core CPUs) is a good idea. Intel is also a safe bet when it comes to video although AMD:s latest creations seem to be faster even for video encoding. A MAJOR performance booster when it comes to video editing is dual displays. This accelerates the slowest stage of the editing process, namely the manual part. Go for the largest, most hi-res displays you can afford ! You will probably have no use whatsoever for the 3D performance in the 6800GT. I would rather spend the money on two 6600GT and a SLI system capable of supporting 4 monitors. When it comes to hard disks, you will want the highest possible sequential throughput. Also, more disks are preferable to few faster ones. Wasting money on SCSI makes little sense for video in my experience. With 1 GB of RAM, it will not make much difference going for a 7200 rpm system disk compared to something faster. You will normally have use for 4 separate disks for optimum performance during video editing. One for system (and page file), one for source video, one for destination video and one for temporary files. You can go even further and put audio and other stuff on separate disks. Any or all of these can be accelerated with raid 0 for more performance. Most of the new 7200 rpm disks are good today. I prefer the Samsung 250 GB for highest sequential throughput, lowest noise and lowest energy consumption.
  14. If you are concerned about power consumption, you should definitely get yourself a power meter that allows you to see the wattage in real time. I recently did and was really surprised. I have measured 3 computers so far. My workstation, a 3 GHz P4 with two harddisks, ATI 9800 and two monitors, uses up 200 - 300 W depending on load. The surprise came when I shut the system and monitors down (with the power buttons). They still consumed 40 W ! It turned out to be the 19" LCD monitor (a new one from HP) that really didn't stop using power when turned off. The CRT was also using some power. My permanently active web server uses up about 40W. It is built on a VIA 1200 Hz Nehemiah board and a Samsung 7200 rpm harddisk. My old 1200 MHz Celeron (Tualatin) with a bunch of ISA and PCI cards and a 120 GB harddisk used up 66 - 70 W depending on load. Then we have all the other electronics that is wasting power even when switched off. I have now started to put external power switches on everything to reduce this waste of power. Sorry not being able to answer your question but you may want to look at the big picture if your intention is to save power.
  15. RAID5 seems to suck performance-wise until you use a lot of drives (more than 4). It would probably be a better idea to use a bunch of cheaper and smaller drives if performance and RAID5 is interesting. Samsung makes the most quiet and coolest running drives and the 80 GB single platter SATA is probably the best for this purpose. It is really inexpensive these days so you could get a lot of them for the same price. If you do buy Samsung drives, make sure you get the ones with NIDEC motors (not JVC). They are more quiet.
