I have a DC20 and want to add 2 4.5 GB scsi drives to my system so I can
play back 30-50 minute .avi's without dropping frames etc as I do with
the EIDE's I have now. I've been told to upgrade from Win95 to NT as
WIn95 doesn't recognise drives larger than 2 GB, and can't stripe two
4.5 GB drives together as 1 (GB drive so I can play an hour continuously
(oh for a ///FAST machine...)
Anyway the guys at Miro tell me that scsi drives would burn out playing
for this long (I'm planning to get IBM fast-wide scsi drives ) and that
Video for Windows can't handle >2GB regardless of Win95 or NT.
Help!
Does anyone out there know the truth of the situation? Can I stripe two
4.5 GB drives together as one and play an .avi continuously from them?

I don't know about Video for Windows.

You can go ahead and add the drives to your system but you'll end up with a
bunch of 2GB partitions under Windows 95. Under NT you'll be able to use
the entire amount of the drives, and even stripe them for a single volume
of 9GB. There are DC20 drivers for NT but I don't know how stable they
are.
Either you misunderstood them, or the guys at Miro are somewhat misguided.
You're not going to "burn out" any drives by doing a continuous sequential
read (or write) for one hour. This is a relatively EASY operation for a
disk drive to perform. I don't know what the file size limit on Video for
Windows is so I can't comment on that. Perhaps one of our NT users can
elaborate.
I do have a solution to your problem but it's going to cost about 5 times
what the Miro solution costs. The Plum card allows you to "print to video"
directly from the Premiere timeline. They call it "Plum Play" and it
eliminates the need to use the "make movie" command to create one big long
avi file. Essentially, they pick up the individual avi files as they go,
from where ever they are on whatever disk. Total cost is $3995. If you
already have a Pentium system (133MHz, 32MB) that uses the Triton chipset
you'll be in business. No more "make movie", no more dropped frames, no
more 2GB limit. The system includes RS422 device control.

I just read a review (Sept 96 DV Magazine) of the Plum and the author said
that there are no current drivers
for Win NT. So you still have to deal with 2 gig partitions. I heard that
Plum has
the ability to read a file across partitions, however, that was not
mentioned in the article.
Also, I don't see how you can get away from rendering the files if you
alter the clip in any by using a
transition or applying a filter.

Was the article positive though?
Take a look at their web site http://www.iimages.com. Lots of info
and explaination as to how it works.
I'm very interested, but I'm out of $ for now.
Miro has DC20 drivers for NT - in beta. Final versions should be
released shortly. Note that the problem of 2gb max partition size is a
Windows 95 / DOS 16bit FAT problem. A Windows 95 service pack #2 is
supposed to be in beta testing soon that is reported to have FAT32.
This will hopefully be a solution to the 2gb limit, and hopefully help
improve access times... As for burning out drives... I see no reason
why playing long AVI's continuously for years on end would be a
problem. Most of your data will all be sequential, non-fragmented data
that won't make the heads on your drives work very hard at all. Anyone
who runs an active NetWare or NT server that is up 24 hours a day is
putting their drives through a much more rigorous existance.

The do render the effects (at about 300-400% enchanced speed) and
seemlessly merge them into the video playback (which is all done
real-time).
