I have a 7600/132 with 1.1 Gb Hard Disc. I would like to either add another HD or replace this one with a larger capacity HD. Can I fit a PC ide drive? Any advice would be welcome.

Have you looked at adding just a narrow SCSI Barracuda? 18GB, narrow 50-pin, ~$199?

To use IDE I think you need to use a PCI card (ATA/66+) and then, yes, you could.
The fastest would be to go w/ Miles2 Ultra2 SCSI and a wide 68-pin drive.

There is a full database you can search on www.xlr8yourmac.com (http://www.xlr8yourmac.com) on cpu, drives, etc and see what 1000's of others have done. They also have upgrade reports, benchmarks, reviews. Any time I contemplate an upgrade, that is one essential stop. But then I'm thinking of upgrading almost all the time !!

Adding RAM, cpu upgrade, faster/larger hdd, video card, maybe FireWire/USB to max out that system.

HI John,

Yes, like Gregory says you can either add a drive to your current bus. r add a PCI IDE card to add IDE suport to your computer. There really is no such thing as a PC IDE drive, only IDE drives that have been formatted for a PC. All Macs since the Beige G3 have come factory installed with IDE drives.

IDE drives are cheaper because A: They make more of them. B: The are simpler and not as 'smart' as a scsi drive. C: They mostly come with a 3 year warranty where scsi drives come with 5 year warranties. D: In most cases scsi drives far outperform equivalent IDE drives.

If you want a scsi drive that will just install on your internal scsi bus goto: http://www.macgurus.com/shoppingcart/showrampage.cgi?mg_hdseagates.html

The very top Barracuda is one of the best drives ever made and one of the last narrow drives available to fit your internal bus.

You can also as Gregory mentioned install a scsi host card and cables like the Initio Miles2 that will speed up your hard drive performance by a factor of 4, at least, when used with LVD drives. YOu can find the Miles2 on this page: http://www.macgurus.com/shoppingcart/showrampage.cgi?mgscsiinitioboards.html

If you want to get a IDE host card and drives this is the page to look: http://www.macgurus.com/shoppingcart/showrampage.cgi?idepagesofheck.html

All of these options will work well in your computer.

I also have a 7600. I am currently in an upgrade process. I have learned some things. I tried and returned a SIIG card. Although many swear by them I am swearing at mine. It may be another problem entirely but, I just picked up the Sonnet card and, as soon as I am done recovering my directory, I will plug in the Sonnet to my New Maxtor.

Aside from my challenges, which I don't think are normal for this type of installation, here is what I have learned:

When the SIIG card was working it seemed so much faster than my stock 7600 scci. It really is like getting a whole new computer. I VERY much recommend going with the IDE Sonnet upgrade.

You hear a lot on these forum pages about the divinity of SCCI, LVD, etc. With all respect, I wasted too much time fretting about that decision. The IDE upgrade is plenty fast enough for me.

You hear about sound stuttering problems with those cards. But I found none of it in the SIIG card, nor have I heard that it still exists on the Sonnet ATA 100. The ATA 66 cards were a little iffy with that.

For about $100 for the IDE card (get the Sonnet) and another $80 - $120 for a new Maxtor or other cheap IDE drive, you will be looking at read and write times close to 30 MB/s on the 7600 (I also have an XLR8 G3/400). As opposed to the less than 10 MB/s you have now. I didn't really understand what those sorts of numbers actually meant until I had the SIIG working. From the time I hit a macro key on the keyboard that launched IE (OneClick), it was just 2 seconds before IE was fully up and running. I also have DSL so in 2 seconds Google was ready for a lookup.

So, just my .02 but, look at the cost of the new SCCI drive and compare that with the ($100) IDE card and maybe $99-110 for a 60 gig really fast Hard drive (75-$85 for 20 gig).

If you just need more storage and some speed increase get the Barracuda.

If you really WANT a SPEED jump get a PCI host card. IDE looks good.

I had a stock 1.2 gig in my 7500 with the G3 400MHz upgrade. I added a 10k Cheetah and the Miles card and WOW http://www.macgurus.com/ubb/eek.gif Just like levelbest said - it was like a new computer.
