Fastrak/66 vs Ultra/66

I know Promise do two DMA66 cards and the Fastrak has a RAID ability. My question is that if running under NT4 (and Win2k in the future) you use the cheaper card and set up a stripe array using NT's disk administrator how much performance difference is there.

NB I am planning on building a new system with 4 IBM 18Gb disks (1->system 3->raid0)

Cheers

When working on raid systems in the past raid 0 wasn't the one that killed performance in NT, raid 5 is bacause there are calculations to do.

If I were given a choice I would prefer to go for a hardware implemented soloution, but it is not so important on raid 0.

54Gb eh 4 hours of video are you doing a remake of gone with the wind?

54GB isn't a lot these days; I'll have more than that next month when I buy my new drive. When you think about editing feature-length movies, only having storage for four hours of footage suddenly starts to look pretty tight.

BTW, as far as I'm aware the Fastrak uses software RAID too, so there probably isn't a lot in it when compared with NT's software RAID.

The machine is for our college TV station so rather than editing feture length projects we need the space because there is usually 2 or three half-hour long programs being make concurrently.

If the Fastrak implements the RAID in software what are they chargeing an extra fifty quid for? I assumed there was a DSP onboard to reduce the load on the main processor. I guess the fastrak is basically the same hardware but with Raid capeable drivers thrown in.

Mind you I just realised that the Matrox RT2000 card which I was going to put in the machine only has Win98 drivers, so I won't be able to use NT's software striping anyway.

Yeah, I believe you're paying the extra for the software. But that's true of many cards, e.g. the DV300, which is an Adaptec 8945 card with Premiere and Pinnacle drivers. Hardware isn't much use these days without the software to control it.

I use a different setup on My machine under NT4 SP5 with the Ultra66 controller.
I moved my hard drives off the motherboard Ide controller, leaving just the CDrom. I then have a system Drive (fuj 3 gig,) as master with a 4 gig System Partition and 9 gig Data where I put programs etc etc.
I then have a 25 Gig IBM as slave. AVI projects. I then have one fo the switchable trays in which i have a nmber of Maxtor 20 gig's that I swab in and out. BUT MUST SHUT DOWN AND REBOOT.
This IMO gives lots more flexibilty. I can then work on projects either inthe fixed or removable or move things from the removable to the fixed. IMO while the RAID is good for makeing one HUGE drive. You loose the flexibility of swaping and storing projects that you are working concurrently off line.

Just a thought
