Startech.com RAID 5 array seems a very slow, wondering if there is a problem

[David Roth weiss]

First, do you have ANY other FireWire devices plugged in?

Second, is the Startech enclosure possibly 3G, not 6G? (Some 3G devices can accommodate 6G drives, but at 3G speeds, while others are simply incompatible with newer 6G drives.
(***FYI, I just checked, and your Startech array does have a 6G backplane.)

Also, when you purchase the least expensive consumer solutions they sometimes fail to operate as expected in a video-centric domain, because they were not designed for high demands required by video.

There are many really good video storage companies advertising here on the Cow, and they specialize in fulfilling the needs and expectations of professional editors like yourself – when users try do it yourself solutions using consumer parts they typically have only a 50/50 chance of success, and when they fail that costs both time and money. The bottom line is, venturing into untested waters in our business is “false economy.”

You are roughly on the data speed of FW400.
I don’t think the drives minimize the speed. I think that you have other devices attached to your computer on the same bus.
But more than around 70MB/s data speed won’t be possible with FW800 and Raid5. Your best connection is the eSata.

Yes I am or that.

I tried eSATA and got almost 200MB/s which is great.

With eSATA I have to boot my PC with drive on to get it to work which is not ideal but I am going to give a eSATA to USB3 adapter a go.
