I would like to hear your guys experience with the ata100 7200rpm ide drives out there. I run scsi right now so I would just like to know how ide performs.


Thanks

There was a thing on Pogo Linux that says IDE is more cost effectivr then SCSI and out performs them.I will try to find that page.

The bottom line these days:

- cost per GB, IDE comes out WAAAAAY ahead
- under heavy load or multitasking, SCSI will outperform IDE by a long shot

For a lot of servers, IDE is just fine these days. I wouldn't run a virtual hosting server on it, but for a DNS server or low-end dedicated server? Sure.

Basically, as Travis has mentioned, it all comes down to what type of computing you are doing. If you're going to be doing a lot of multitasking, then possiblly the SCSI will be a better choice. SCSI is also the better choice for a client-server type architecture where simultaneous I/O calls are made. However, if you don't do a lot of multitasking and consider yourself an ordinary desktop user, then EIDE may be your better choice. Afterall, once again as Travis mentioned, you will get more bang for your buck and the performance will be just as good, if not better than the SCSI.

I remember someone saying that deleting a large file, ie 40 megs or bigger, is much quicker on scsi then ide

another great site is www.storagereview.com
good articles and tests on dif drives a database to compare drives

IDE is good. Unless you go with 15,000 RPM SCSI -- I say stick with IDE. Get as much RAM as you can, RAM is way cheap :) These are just general statements...

Specific info:
For a 1u server where I can only cram 2 drives in anyway... I go with IDE, each drive on one controller channel.

AVOID putting more than one device on the same controller. It is pretty easy to find motherboards with 4 controllers, or I use the Promise Ultra66 / Ultra100 cards.

I find a lot of the 1u servers don't do this right. Intel ISP1100, VALinux 1000 series, IBM 4000R, Network Engines Blazer. All these machines have both hard drives on same controller. When I get them, I rework them so that each drive is on unique controller. If you have a database system that keeps logs, this is very important under heavy writing load.

The key to good web server performance: Stay off the hard drive whenever possible. No use of hard drive is best! SCSI or IDE.

Thanks for the information everyone. Ill go check those websites out.
