Worth going to XPe for this application?

[Guest]

I'm working on an embedded application the will primarily be moving high
speed data off an IO card onto a RAID while also performing a few other
controls and IO tasks. I'm trying to decide between Windows XP and XPe:

We have a different non-embedded application that performs a similar task
fine using Windows XP, but it is on a rather powerful PC.

This is for in-house use only, so XPe's ability to restrict/change the shell
doesn't matter for us. I'm wondering if there are other benefits to XPe that
might justify the extra effort/expense.

Our embedded hardware is considerably less beefy than that for the
non-embedded application mentioned above. We will also possibly be booting
off a Compact Flash card (though we might be able to boot off the RAID).

Is there any benefit here to go with XPe? It occurs to me that XPe's
ability to remove unneeded modules might help performance a bit by removing
some unnecessary overhead. Is that correct? Also, I assume XPe can boot off
a Compact Flash card, yes? Can regular Windows XP do that?

Thanks!

Hi LintMan,

Some of the things you're asking for is the primary reason XPE's out
there... reduce overall footprint, Boot from Flash, ETC...

Yes you can make XP Pro boot from Wear-leveling flash, but it's tricky at
best, and you will not get the best life from the card... you'd have to turn
off VM in XP pro, just like XPE... One of the big reasons for XPE is the
Write filters, and flash boot. - the write filter essentailly protects the
OS, but what it also does is enable a psuedo XIP for the OS, as the OS is
actually executed in RAM, so the Flash card is not worn out so quickly. with
the advent of the new File based write filter, you also get to allow certain
things to persist, so it makes this scenario that much better.

HTH,

It would be worth a look, I believe...
