>>>Can a SCSI HD have 2 cd contents copied onto it at the same time or does the 2 CD drives have to be SCSI too instead of IDE to beable to do this?
Well, provided the CDROMs are on seperate IDE channels, they should both be able to read simultaneously, and the SCSI drives can be writing simultaneously also.
Only time i've seen this not work was with a cheap-ass Avansys SCSI controller - it would wait for IDE read operations to complete before writing.
That doesn't make much sense I know, but it happened nonetheless. Dont skimp and scrape when it comes to your controller!
>>>Also could you defragment your SCSI HD while copying 2 cd contents onto your SCSI HD without messing up the defragment?
Uhhh... no way :/
It probably wouldn't "mess up" the defrag, itd just re-start the defrag process every few seconds.
How can you expect your computer to organize the filesystem, if you're changing it every few moments?
>>>And could you do gaming at the same time, then watch a streaming video then test out your hard drive performence in Sandra or HDtach while all of that is going on?
That would be kind of silly...
The benchmarking programs are supposed to test your HDDs performance by putting extreme I/O load onto them.
Not only would the game concerned have a hard time getting data quick enough, but the numbers you would get from Sandra would be useless...
Why do you want to know what your HDD performance is while running a game?
Go a bit further into the game, and your system might need more disk access for that particular level, or whatever.
The results would be completely innaccurate, useless, and un-replicable.
If you want to know how much load is on your HDDs during a game, read a FAQ and enable disk performance counters, then run performance monitor in the background while you play the game.
>>>Then while all that other stuff is going on could you use internet explorer surfing without a big slow down of internet explorer itself? I know how with IDE
>>>the internet explorer surfing feels somewhat slower when you are copying file onto the HD and stuff while surfing the internet.
Ummm... Copying while surfing will probably be a bit quicker with SCSI, due to the lower seek times of the drives.
Watching streaming video while surfing, probably has very little to do with your disk throughput - more your video card (the video puts load on it) or CPU (utilised heavily by multitasking).
The idea of benchmarks is to find the maximum speed of a given component.
You should never do anything else while benchmarking - you shouldn't even move the mouse, let alone watch video or web.
The more work your system has to do in the background, the lower the benchmarks will score - and thats not really going to prove anything.
It sounds like you're thinking about SCSI but you're not sure whether to bother or not...
IMO, I think you should look at more than just your disks.
