Re: partioning HD w/NTFS

Too wide a brushstroke there, I think:
That's true only if the drives are all on the same physical
drive. Multiple physical drives can and do give an improvement
when they're set up properly.

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?
