USB 2.0 as the second drive 1

Is an external usb 2.0 hard drive fast enough to be the second drive for a/v input and output.
I would have just one hard drive in the computer.
thanks
 
USB 2.0 is limited to 60MB/s. And if you have multiple USB devices, that number is even lower for your hard drive.

At those speeds, it's OK to use the drive for storage. However, I wouldn't do any video-editing with files on that drive.

An internal ATA/100 drive can average as high as 45 MB/s transfer rates.

An external USB 2.0 drive will average 20 MB/s at best depending on the number of devices sharing the bandwidth

sounds like everything that is gained by a second drive is lost by having it external
thanks
 
Well, another way to look at it is that it will be roughly half the speed of a decent internal IDE or SATA drive.

50% slower isn't too bad, and it might not be noticeable for some tasks.

If you want to do A/V, you may want to use hard disk drawers for IDE or SATA.


 
can you explain what a hard drive drawer is? thanks
 
On the front of your case, you may have a "blank", to put in another 5 1/4 drive. Instead, you put in a special receiver (like a trailer hitch), that accepts a hard drive mounted in a "drawer". You slide the drive in when you want to use it, and take it out for storage. These are actually designed for "servers" which are "hot swappable" (you can do this with the computer on). Used for security. On normal desktops, you have to shut down to put in or take out. You can have your normal OS, with all your programs on one drive, and another drive with just OS and your a/v programs.
 
But in that situation, why not just put a big disk in and dual boot?
 
You need huge disk memory if you're doing video editing.
The nice part of drawers is that you can install the OS with just the components and the configuration that is optimal for a video editing session. Or even for power gamers that play on the web. Install the minimal components, no networking stuff, no background tasks. The performance of the system is greatly enhanced.
Want to try Linux, or a different system configuration but aren't willing to risk rebuilding your actual setup? The drawer provides a good answer for this too. You can fiddle with the new stuff on a different drive until you feel safe.



 
But again, nothing you can't do with a dual boot. I do the same thing with music production software. Yes, i lose 10gig of storage on the disk for the 'other' OS install but it's not really very much in the scheme of things. So long as there's enough storage for the scratch disk and output files, then there shouldn't be a problem. Having the portability of a removable disk is nice and for that i'd suggest a USB2 drive for the output files. That way you can still take footage elsewhere to work on if you need to. Having a removeable bay relies on any other machine also having one to dock in.
 
I guess it's a matter of tolerance to risk. I do all my day-to-day work on a machine and I don't like getting exposed to an unrepairable system crash because of a new piece of software that installs something that interferes with a tweak that you need to get another piece of software to run. Rebuilding my system hard disk takes a full day. Lots of updates licensing stuff. I paid $12. for my ATA-133 drawers. I considered it a safe investment. Timesign needs throughput for video, so a USB drive is out, anyway.
I do have BootMagic on my machine. Bootmagic was installed from the Win98 partition. I'd like to reinstall Win98. Since BootMagic was installed from this partition what will happen if I flush it and reinstall Win98? Will it scrap my Win2K partition or prevent me from accesing it? I don't know, I don't want to take the risk of finding the answer.


 
There are a number of ways of dual booting, using Bootmagic, GAG, or write the boot sequence yourself. Re-installing onto a partition shouldn't affect this and even if it does, it's very easy to tell it to look for the second OS.

With dual boot, it hides the partition of the OS you're not using, so unless it's a hardware crash it should never affect it. And if it did, you'd be able to restore from backup right?
 
norty,
I'm afraid that's not necessarily true when you're dealing with Win9x/ME. The OS has to be installed before Windows 2000/XP for dual-boot to work properly.

Both share the same boot sector and modify the MBR. Reinstalling Win98 after you already have Win2K installed will lose it for sure. You can repair the installation, but trust me, it's not a fun process.

I learned the hard way! [sad]

Now of course, 3rd-party boot managers can get around this issue, but for those of us who don't use them, it's guaranteed to cause problems...

Whoopsy!! Sorry, I've been living the XP life for so long now i'd forgotten all about those 'other' OS's...
