I really need some help. I am getting two ultra2 scsi drives and a ultra2 adapter for free. The drives are 80 - pin sca drives and are atleast 10k rpm 18 gig. I don't know what brand or model (I'm guessing seagate or fujitsu). I ordered the sca 80 - 68 converters.

Now for the questions.

1) Will I need any termination at the end of the cable? I really don't know much about the differnces between lvd, se, or any other form of termination.

2) Is Ultra2 going to be faster then ata100? From what I have read Ultra2 has a max throughput of 40 Megs. I know ide drives never ever touch a 100 Meg throughput but I know some of the WD SE drives hit 49 sustained and raid 0 can hit about 86. I use my system mainly for games, dvd - vcd conversion, and web surfing. Also work with mp3 alot.

I have never touched SCSI before in my life and any advice, hints, or tips would greatly appreciated(sp?). Also my system specs are as followed.

Athlon xp 1600+
Ecs K7S5A
512 Meg. pc2100
40 gig ata100 maxtor
visiontek gf3ti200 (runs primary display)
voodoo 3 3000 pci (runs second display)

These days the controllers act as one terminator and the last drive on the chain acts as the other.

Should be faster. You'll certainly have faster seek times.

1. Probably not. Ditto the last guy.

2. It really depends on what you're doing. It's probably not going to be 'faster', but it's a hell of a lot more flexable. You don't really see the Scsi difference until you raid 3 or 4 drives together. In that case, scsi (beyond any hope of recovery) completely smoke chex IDE.
