Casey:
Here’s the deal…
MB: SM X5DA8
Relevant PCI slots include 2 100mhz and 1 133mhz, etc. Look up Supermicro’s web page on this MB.Vid Storage/RAID setup:
14 300gb Seagate SATA HDDs
2 4852 controllers, in 100mhz slots. 8 drives connected to one controller and 6 connected to the other. 2 RAID-5 arrays (each 1.9TBs) across both the controllers, including all the drives.
The speed difference you are concerned about is probably because all 14 of my drives are part of the “Volume” being tested.
One issue I ran into when I first setup the 4852s was that one (or two, can’t remember) of the HDDs individual throughput speeds was way down compared to all the rest (using iometer). Individual speeds using iometer should run from about 50 to 63mb/s Read and Write. If you have any HDDs testing below that, you need to exchange it/them. One slow drive will slow down the entire array. In my case, the faulty drive ran about 20mb/s–definitely faulty. If your speed tests are producing widely varying results and/or very low numbers, you might want to run iometer on each drive. It’s a hassle, but the only way I know of to find the bad guy(s), if any.

Whoa! You folks that choose to run RAID-0 are either super confident souls, have never had a drive in your array fail or enjoy recapturing footage. Is the less-than-dramatic difference in Read/Write speeds (and overhead) between RAID-0 and RAID-5 absolutely necessary? If it is, perhaps you have no choice. I hope you have a way to backup all your vid files (and have done so), or you really don’t have all that much on your array(s)at a given time, so that a drive failure won’t cause your mouth to go dry and your life/career to flash before your eyes.
If possible, setting up a RAID-5 array to test whether or not it is fast enough for your kind of work would be time well spent. Living on the edge is fine, until Murphy shows up.

Check out Broadcom’s RAIDCore SATA controllers. I’ve been using 2 of their 4852 cards to connect/control 14 300gb Seagates setup as 2 RAID-5 arrays. Using BMD disk speed utility, I’m getting about 380mb/s Read and about 285 Write. While my work is still SD, I don’t know whether those speeds and the overhead that comes with them will work with your HD material.

Is it possible and does it even make sense to intall XP64 in a system that still has a 32-bit MB and Xeon CPUs?

Shane:
Though I have not yet installed XP64, it is an entirely different OS, not an upgrade of XP32. So, you’ll have to wipe the drive/partition and do a clean install.

While Viewsonic made pro-level CRTs, I don’t believe their LCDs are all that great (never could get them to tell me who manufactured their screens). I bought one of their LCD HDTV monitors, and returned it almost immediately the image was so watery and the colors so far off.

They’re working on a driver for XP64, which should be out in the not too distant future. And when it arrives what wonderful moment that should be for those of us working in long-form.

I too upgraded recently and went with a nVidia 6800 GT in spite of the fact that Adobe suggested (among others) a nVidia 6800 Ultra. The GT works just fine and is quite a bit less than the Ultra.

I’m in Dallas, and no, I haven’t talked to Grant, but I have had conversations with Andrew regarding other issues. I’d very much appreciate your asking your contact(s) there about this RAM issue. Thanks again.

After you add /3gb to the string (with a space between what’s before and after it) and then re-boot, you should open Control Panel/System to see if “Physical Address Extention” appears at the very bottom of the window (below the amount of RAM). If it does not, then it didn’t take, as in my case. Instead I added /PAE
Why the /3gb in my system didn’t take, but /PAE did, I’ve no idea.
