Hi Jason,

Changing to a BIGINT shouldn't cause any corruption - I will make the changes myself to the article.

If you are getting IO sizes of 256 then it probably means sql is doing read ahead which is good for performance, take a look at http://technet.microsoft.com/en-us/library/cc966500.aspx "Read-Ahead" for further details.

It does say that editions under enterprise are limited to 128 pages so you should divide the 256 by 8 (8kb = 1 page) to give you 32 pages.
