Pinnacle Capture

I'm not sure if this is the right place to ask but,
I am useing Pinnacle Plus 9.4 to capture family video, if the 200 Gb
harddrive is on my normal IDE interface the "Test Data Rate" is about 25440,
If I put the drive on to the RAID interface (useing it as a normal IDE
interface) which is where I would prefer it to be, the "Test Data Rate"
drops to 10770!
Anyone any constructive suggestions

Regards
Mike

RAID your drives should all be of the same size and type and speed.
The RAID types that are most commonly used are:

RAID 0 is striped, and is not really redundent at all. It allows for
faster speeds, the more drives the faster. It requires at least two
drives of the same type. If one drive is larger than the other, then
it should only use the smallest of the two as the max size for the
larger.

RAID 1 is mirrored, and allows for writing simultaneously to two disks
of the same size. It is truly redundent, but gains no speed.

RAID 5 is striped with parity, and requires at least three disks of the
same size. One disk is used for parity. It allows for faster speed
with fault recovery should one disk fail.

RAID 1+0 is mirrored and striped. It requires four disks of the same
size. It gives redundency of RAID 1 and speed enhancement of RAID 0.

Hardware RAID is the only one that I would recommend, i.e. built into
the controller.

Probably the other controller has DMA turned off (that is Direct Memory
Access, a way of doing I/O without involving the CPU in each step of
the process).

Look somewhere in Device Manager, or if you have Intel Application
Accelerator, somewhere in there. Or else, somewhere in the software
associated with your RAID controller.

By the way, I have used my RAID controller to run only one drive with
no problems at all (except figuring out how to do it!), so I seriously
doubt if that is where the trouble lies.

HTH,
Gino

Hi Gene, I would be very interested in knowing how you got a single drive to
run on RAID

I did it a couple of years ago, so I forget the details (also, since
then I pulled the internal drive and put it into a USB2/FireWire
enclosure).

Here's what my (fading) memory says: I installed the drive. It was an
IDE, by the way, since my MB has a funny controller with two IDE slots
and one SATA (Asus P4PE). Once the drive is in you first go to the BIOS
setup to enable the RAID controller, then you get a setup screen on
booting. On that screen I followed the steps to set up a RAID, and I
told it what kind of RAID I wanted, striping or mirroring, and only one
drive.

It took a couple of tries experimenting with the various parameters to
get it to work, but I now forget which set worked.

I hope this gives you at least a reasonable beginning,
Gino

RAID 0 with one drive should be the choice. My original post was a bit
misleading. Normally, when one does RAID 0, they use two or more
drives. I do have several systems with a single RAID 0 drive, others
being mirrored or striped, etc...

Post Script: It may also me JBOD.

This is not a joke. JBOD is a technical term for *Just a Bunch Of
Drives*. I believe that Promise uses this term.

Every RAID controller is different.
