Jumper cables on 400 GB Seagate SATA

[roshi]

I got two of the 400 GB SATA Seagates, to replace my G5's internal drives. What I want to do first is clone my existing internal partitions.

I have an OWC quad interface external drive case.

The Seagates came with jumpers on them, to slow down the data transfer.

Can I just take the drive jumpers off and forget about them?

The Seagate manual says they are to limit the speed to 1.5 Gbits/sec for older SATA cards.

Which G5 do you have?

Man, how much did you pay for those drives? They'll do faster than 1.5 Gb/sec??

Leave them on. They may even be necessary. Your G5 doesn't do better than 1.5 Gb/sec anyway.

G5 is the dual 2.3 Ghz.

The drives cost $110 each.

>>The drives cost $110 each.

I was joking. Even if the drives claim to support 3.0Gb/sec they'll never get close to that.

Only the new Mac Pros support 3.0Gb/sec.

Do I leave the jumpers on or not?

You leave the jumpers on. The last rev of G5's also support 3Gb SATA.

Never say never There are some RAM drives which are much faster than that. But results from 1.5Gb drives vs 3Gb drives show the 3Gb drives are faster (though if that's because of the interface, who knows.)

The G5 could be the last rev G5. I bought it in December 2005.

Is it DDR or DDR2 RAM? or, is it dual processor or dual core?
