Hi Group,

I googled this groop but I can't find any answers about this so I post here.
We're providing systems for image processing purpose hence the RAM usage can
be really important sometimes.
I understand that adding a page file to CF will wear it down pretty quickly
so I wonder if replacing the CF by a (fixed) microdrive could be a good way
to had a page file to our image.
Does anyone know the max read/write cycle that can be done on a microdrive
and the transfer rate? Any (broad) etimation will be greatly appreciated.
I think microdrive are like small HDD thus the life cycle shouldn't be a
problem with a page file, am I right?

Regards,
Alexis
 
I don't have the numbers, but the microdrive isn't any better.
Microdrives aren't rated for 24/7 operation. Usually 20% duty cycle is
specified.
And, they are usually rated for 100k head load/unload/standby cyles. Do the
math. The Hitachi drive I tested did unload/standby after one second of
inactivity. So, if you are unlucky enough to have page file actvity every
1.01 second, you have a month for the lifetime.
We found our only option was a real harddrive or more memory. We couldn't
do either. So, we attacked the programs and the OS.

To reduce OS size consider this:

Hi Mark,

Have you tried playing with :
http://www.microsoft.com/technet/pr...Kit/4d957288-cfb5-4ad6-b96d-ad27f999ef5a.mspx
Look in subtree for reg value descriptions like NonPagedPoolSize.
By default all these values are set to 0 which is automatic calculation.

We gained 30mb of memory for programs by tuning the OS memory pools.
