Will a USB External Drive Suffice for Editing in Vegas?

I am currently using 1394a external hard drives, but have a problem with one of the drives dropping off when I add a camcorder to my system (for capture).

Because of this issue, I was thinking about USB this time around.

My primary workload will be adding FX filters to an AVI file in Vegas 6.0, then exporting.

Would I be digressing by going with USB?

I use USB drives all the time (at work and at home) and haven't had any problems whatsoever.

Ditto.

Camcorders interfering with hard drives on the IEEE-1394 bus is a well known issue. Many of my external drives are USB and FireWire but I always use the USB option.

Wait Alan!! there is a get around to the problem. I always load the camcorder first and get it regonised before starting up the ext HDD. It works fine. Firewire will be better for editing. I have both options with USB and Firewire.. my advise is to go for the latter.

I use external/usb for both editing and capturing. You just want to make sure you don't get a crappy drive. I would stay away from generic drives. Honestly, one of the best things I have is an icy dock usb/firewire bay and I just swap drives in and out. It's like butta.

I run my deck THROUGH the drive :-)

Computer -> firewire -> hdd -> firewire -> deck

I can still capture/PTT with that external drive in this configuration as well!

One of the things that can happen when you daisy chain the drive and the camcorder/deck is that the IEEE-1394 bus will drop its speed to that of the lowest device on the bus. Typically, this is the DV device and can result in the drive running at 100Mbps instead of the expected 400Mbps. Whether this happens is very specific to the camcorder/deck. Either way, the bus can only support 400Mbps in total so if data are being transferred to/from the DV device, it will take away from the overall bandwidth available to the drive (though a drop of 25Mbps + overhead is relatively minor).

One point regarding USB external drives. I use two Seagate 320GB Barracuda drives for storing all my master HDV video clips etc. These were relatively cheap about 6 months ago and seem to work really, really well on USB 2.0 ports. They are 7200 RPM, both set up as NTFS (not FAT32) and have a 8MB internal buffer.

I was wondering if the newer external drives with 16MB buffer that are starting to appear everywhere now might be better for video editing?

Any comments from anybody that knows the details on this kind of stuff?

Andy

Just bought 2 USB drives

I just purchased two Hitachi 1T USB drives.

Each has a 32mb buffer.

If I load a file off of that drive, and a copy of the same file off an internal 10,000 RPM Seagate drive, there is a noticeable difference in performance.

The Seagate drive is 150 gig and cost twice as much as the Hitachi.

I also have Firewire drives, but use them for normal data, not video editing.

For the price, $199 each, I could not pass on the Hitachi drives.

I am also editing AVI files, as opposed to smaller MPEG files.

I assume you are seeing the internal drive being faster.

Current generation external USB and FireWire drives will never compete with the speed of an internal drive, especially modern SATA ones. Depending on the flavor of SATA, it can achieve transfer rates of 300MBps, i.e., 2400Mbps compared to both USB2.0 and FireWire 400's approx 400Mbps.

USB drives also consume a little CPU power.

My external drives have both USB2 and Firewire 400. When I capture from my camera it is plugged into the firewire and the drive into USB2. When I'm editing I switch the drive to firewire. Less use of CPU cycles and it works great.

Where are 1Tb hard drives for sale at $199, that is all I want to know! Never mind, I see now that they were external drives.

A bit off subject, I personally have moved to all internal drives. I set up a server last week due to the slowness of externals. Externals are great for mobility, but I got tired of them otherwise, especially the firewire issues.

I took an old tower that accomodates many drives, and hooked it up to my workstation via ethernet which is a 1GB per second connection. I run raid 0 on 2 sets of 500GB SATA drives and back up everything twice. Transfer rates are extremely fast. Since I run an ethernet connection for my broadband, I had to add an inexpensive NIC card, but otherwise it was an almost no cost solution to my storage issues.

Tell me more about your setup.

Does your ethernet connection between the two computers require that you be running server/networking software, as opposed to plain Windows XP?

thanks..alan
