Suppose you have a <big>big<big> Microsoft SQL Server 7 database and
suppose you put the data and the log on different drives (for
reliability and performance). What is the best allocation unit size to
format the drives with for the data drive and the log drive
respectively? I've read that SQL server uses blocks of 8K and does a
read-ahead of 64K, and the log is read and written in 32K blocks. So is
the best allocation unit size for the data drive 8K or 64K and for the
log drive 32K or is some other value better? (Note: assume that no
other stuff is stored on the drives).
