I've decided to place Windows updates on a seperate partition but im not sure how big to create the partion? Any ideas?

Its for a Windows 2008 SBS installation and collecting everything apart from drivers

I would suggest at least 100GB

I have an entire Server 2008 installation with all updates in place and the whole machine is about 30Gb (commensurate with a Vista or Windows 7 machine). So 100Gb seems a bit large. I think just updates alone should be comfortable in about half that (50Gb). Let's see what others say. ... Thinkpads_User

It all depends on what Software you will be updating, if you need all versions of office, and all updates from XP-Win 7 60Gb will be more than enough, but if you have a lot more 100Gb as iSiek has suggest is better.

What software you will be updating. If you only do workstation, SBS and office you will use about 40Gb

As Dave_AND notes, "it depends". There is no formula I know of to do that. ... Thinkpads_User

Every Service Pack for Windows reaches maximum of 400Mb, so take number of unique OSes installed and multiply it by 400Mb. Result should be enough including drivers storage.

We have deployed a number of SBS 2008 Servers, but do not use a separate partition, although we did look at this as a possibility.

I would suggest that 30GB would be suitable.

WSUS maintenance should be run on a regular basis.

If this is done, then I think you will find 30GB is plenty of space.

However this is for networks with 2 server configurations and 2 workstation os and 2 office OS. Some organizations are running 4-5 workstation OS (32/64bit) and several more server OS, and as such more space would be required.

I would recommend that this partition be placed towards the end of the drive if you do create it, as performance on this is not critical.

Running maintenance about 1 month after initial WSUS is very good idea to keep on top of everything as well.

so the cleints connected to WSUS tells it which updates are needed and then WSUS download the appropriate updates?

@ resolver1: The client just get the already approved updates from the server not asking the server for the needed updates.

when deploying WSUS you should determine all microsoft updates that will be distributed to the clients either by automatic approvals or not also the languages.

Attached is a very good document that will helps you in the implementation and understanding.
