Do the master / slave configuration reduce performance ?

[boyz]

Hey guys i would like to know if the master/slave configuration will reduce performance ? thanks

If both devices on the same channel are operating at the same time it will. I believe IDE can only address one device on each channel at a time.

one of the hard drive is a ata 100 and the next is a udma 133.

Doesn't make a difference. They will just operate at ATA100 speeds which isn't a big deal because no hard drive on the market can supply enough data to flood an ATA100 channel.

If both drives are being used at the same time then you might see a slowdown.

copying from drive to drive might not be the "fastest" but it will be okay.

You are correct, that it doesn't make a difference, but you are not correct when you say that both drives will operate at ATA100 speeds. Modern IDE controllers support independent device timing. Each drive will operate at it's maximum speed.

There may be a slight slowdown, but this is dependent on configuration of the computer. More likely than not, even if both drives are operating simultaneously, neaither drive is pushing so much data that the bus will be overly saturated. The difference won't be noticable by use, only by benchmarks. Unless there is a lot more than just 2 drives using the bus.

kinda OT here, but when it comes to RAID 0, is there a big drop in performance when the two hard drives are sharing the same channel? I have a sytem with only the 2 built in channels, but the secondary is being used for the dvd and the cdrw drives. I was just going to use built in software raid that is in Windows 2000 or XP. thanks in advanced

Hmmm I didn't know that. Thanks for correcting me.
