Hi everyone, I read this in one of the mini linux manuales. Linux Partition HOWTO, Kristan Koehntopp, kris@koehntopp.de,v2.4, 3 November 1997. Is say: "Step on soapbox: And I am talking about real tapes, not that disk controller driven ftape crap. Consider buying SCSI: Linux does support SCSI natively. You don't need to load ASPI drivers, you are not losing precious HMA under Linux and once the SCSI host adapter is installed, you just attach additional disks, tapes and CD-ROMs to it. No more I/O addresses, IRQ juggling or Master/Slave and PIO-level matching. Plus: Proper SCSI host adapters give you high I/O performance without much CPU load. Even under heavy disk activity you will experience good response times. If you are planning to use a Linux system as a major USENET news feed or if you are about to enter the ISP business, don't even think about deploying a system without SCSI. Climb of soapbox." But what about "(E)IDE"??? or other drives? Why only SCSI? I am building a new system together and ofcourse I am doing all the research first before I bay the main parts and software. But I cannot find anywhere the answer. Thank you all! :-) Alexander :-) apuschumann@yahoo.co.uk

From what I've heard, Linux treats all hard drives as if they are SCSI. It then in turn fools itself by dealing with IDE drives... Your IDE drives should work just fine... That guy was just talking a bunch of theoretical crap

Thnak you B! But if I use a IDE rather then a SCSI will there be a performance reduce? What are the main ressions that "Linux treats all hard drives as if they are SCSI"? I use Linux all the time and I have use IDE I/O software to set the drive, What is the softawre there for then if it is treating the the drives as SCSI, to help support to the IDE drive? Thank you.

I don't know about scsi, but I have been using EIDE hdds for years, and don't see performance degredation between Win98SE and Mandrake Linux 8.2 Powerpack Edition. SCSI drives are very expensive. Granted they are for very hard usage. My system has 4 (yes FOUR) 60 gig hdds, all ata100 and perform superbly in both windows and linux. I also have ata33 cdrom and cdrw drives. Two of the hdds are on a Promise Technology Ultra100 PCI EIDE controller, the other 2 are on the mobo's ata100 primary channel. Charles

Hello again :-) What are the main ressions that "Linux treats all hard drives as if they are SCSI" and why are SCSI hard-disks more expansive? Are the better in beformace and last longer? Thank you! Alexander
