Re: partioning HD w/NTFS

Wrong. If something wants to read from the pagefile at the same time the
other drive is writing to disk, the pagefile read gets bumped momentarily.
It will have an adverse effect on your system. It is better to leave it on
drive C that to place it on a second drive on the same IDE controller. You
gain NOTHING by placing it on the second drive - same controller. You, in
fact, lose.

Placing the pagefile on a slave drive (connected to the same IDE channel)
buys you a sum total of nothing.

Not so. By having the paging file reside on another drive, at least he
can minimize head (seek) movement. That's worth about 10 ms saved per
seek. Again, if the paging file is the ONLY file being accessed on the
second hard drive or the one primarily being accessed (few intervening
files read off same drive of other files/folders), that would be of
benefit as the heads would always be parked right where Windows paging
subsystem would like them to be.

Remember, lots of background CONTINUAL disk accesses can/do occur with
Windows/XP (NAV, system tasks, NTFS logging).

Additionally, when physical paging occurs, it is usually a SYNCHRONOUS
process to "real work" (user applications) within the system . IOW, an
applications use of memory has caused Windows to physically page out other
blocks of memory. Is there ever paging file activity at the same time for
OTHER disk accesses? Not likely. It can happen if one is launching a new
program (reading exe/dll stuff into memory forcing physical disk paging
into action).


In fact, it may slow the system down. The
two drives write consecutively. When one drive is in read/write mode the
other drive CAN NOT do the same. The time is split between the two
drives.

***
See head/seek placement issue above.



Place the pagefile on a hard drive on the secondary IDE controller and
you can have concurrent reading/writing of BOTH drives. Here you will
likely see a gain if you are using programs that make extensive use of
the pagefile.

***
The final question is: what % of the time is your paging file PHYSICALLY
being written to/read from?

I have 2 HDs on my PC, on the master (80GB) I have XP pro and everything
else. On the slave(40GB)I put a paging file and nothing else. I want to
partition so that my O/S is alone on the master ;so what size will
suffice
for the O/S? I then want to put all the hot fixes into a folder on a
seperate
partition. Then all my games on another then text files on another and
so
on... Also concerning paging file. By having the paging file on a
different
HD other than where the O/S is I'm concerned about the memory dump. How
large should I make the paging file on the master to handle the memory
dump?
And how large should the paging file be on the slave which is accessed
less?
I have 1 GB of memory to play with. Will the /S be able to access the
games
even if they are on a HD without an O/S on it?
