any drive on our Seagate page (http://www.macgurus.com/shoppingcart/showrampage.cgi?mg_hdseagates.html) with a part number ending in LW will work, as long as it is used in the middle of the bus with the current single-ended UW drive terminating the bus at the end.

I would like to get a 18.4 Cheetah ST18404LW To install into the beige G3 mini tower. Is there any other mounting hardware I would need? Can Mac Guru give me instructions for installation?

Thanks,

all you need are four screws to install onto one of the trays under the CD-ROM. A Guru can assist you here on these forums. It is very much a common-sense install.

We will need the details of the SCSI card that Apple installed if you intend to use it to host the Cheetah.

Sorry, I've had a house full of company till yesterday.

I don't recognize that notation. Surely someone will. It couldn't be National Cash Register!

that's an ATTO single-ended Ultra wide. What was the question, again?

I believe I answered this question already.

YES.

as long as you install the new LVD drive in the middle of the bus, flanked by the host at one end, and a terminated single-ended UW drive on the other end.

I also have a Beige G3/333 MT with the so called ultra-wide 9 gig hard disk, and
being the curious sort I reopened the case and took out the scsi card for inspection, as I got the same System Profiler info myself. Didn't think NCR made scsi cards, and the card is actually an ATTO Express PCI card (as Magician noted), and I would like to know if it's actually worth keeping in the tower, as I am also getting ready to get a Cheetah or two? Would the purchase of a Miles2 speed up that internal 9 gig ultra wide drive for the time being, or should I just take the plunge and get a Cheetah or two with the Miles2 for life in the fast lane? Money is a concern (sort of) for the time being, and I am curious to know if just the Miles2 in place of the ATTO would speed things up a bit, if not then a Cheetah will be on order.

One last thing, with the Miles2 can I attach two Cheetahs and derive the benefit of two drives on the chain, or will it slow the card down. I guess I'm talking performance and read/write here, and I've been reading the forums and that seems to be a consensus that two X15s on a Miles2 in a Beige G3 delivers respectable performance. That and have nothing else on the scsi chain, just the drives, correct?

Replies would be greatly appreciated, and in my humble opinion I've actually learned a thing or two on this site, great work and Happy New Year (belated).

using one or two LVD Cheetahs on a Miles2 will deliver superb performance. Regardless of what you do, for optimal performance, avoid mixing LVD and single-ended devices on the same bus. If you simply want to add storage to your existing single-ended ATTO bus, you can, as discussed previously in this thread, add an LVD Cheetah to the middle of the bus. It will run in SE mode. This is not optimal, but it is simple and affordable.

for best performance, with economy, the Miles2 combined with LVD Cheetahs is tought to beat. You should not run SE drives on such a bus. Keep them segregated.
