I would like to post a fair warning to those that apply this reg edit. I have been a big fan of storing my emails and attachments to my card along with the IE stuff (cache, history, temp). However, recently I defaulted everything back to the phone memory due to a bug it can cause. The common bug with this with WM5 (this phone particularly) is that when you power cycle your phone, sometimes your card won't load quick enough or properly. The phone will see that these things according to the reg need to be on the storage card, so it will make that directory before the card is read, then once the card is read it will write it as Storage Card 2. You will only be able to access it through a file explorer. This becomes a royal pain in the rear because the way to fix it requires you to rename "Storage Card" to something like "Storage CardA", then power cycle the phone. 7 out of 10 times this will do the trick and you simply go in and delete "Storage CardA" and you are all set. It wasn't bad with my phone for the longest time, but it eventually got worse, and with the slow boot times on my phone it became unbearable at the fact that when I powered my phone off, and then turned it on later I would have to go through this process. Sometimes I would get to Storage CardE before it would catch. Just thought I would throw this out there as a fair warning, along with the note that emails don't take up as much space as you would think (even with attachments, depending on what they are).
