Hi Phil,

Have a look at :

http://AS400BKS.rochester.ibm.com:80/cgi-bin/bookmgr/bookmgr.cmd/BOOKS/AS4PPCPF/CONTENTS#CONTENTS

see chapter 14: "DASD Performance"

I seem to remember that there was a single IBM-Webpage with infos about mixing
DASD of different sizes and a discussion of performance impacts.
Something like "AS400 Performance Issues" but I cant find it at the moment ...

Maybe Al Barsa knows that URL ?

Greetings from rainy germany,  Philipp Rusch
