My Disk strategy - what do you think?

[blackninja]

I have the following disks:

1x74GB raptor
3x250GB SATA RAID0
1x500GB Seagate

Of note these are the things that I think put most load on my drives:

I use virtual machines constantly for work purposes (1 to 4 at once usually)
I play games
I convert/edit videos
My PC serves media to my PS3

I have a single 74GB raptor as my system drive with 40GB of that for Vista and 20GB for XP
I have all the 'My Documents' stuff for all users mapped to my RAID array
My VMs live on the RAID array
My games are installed on the RAID array
For everything that I want backed up (VMs, Docs, photos etc) the changes are synchronised daily to the 500GB drive using SyncToy and also when I choose to manually run it for whatever reason.
The really critical stuff is also copied to my 320GB external drive (SyncToy again)
If I lose my PC my laptop can manage at a push for a short period for work purposes (4gig, 300gb disks, dual core)

I am thinking of getting another 250GB drive to add to the array and a 1T drive for backups to replace the 500GB drive - the 500GB drive can be used elsewhere.

I am quite happy with this arrangement but I was wondering what other people do and what would be the best way of improving what I have now for the same cost as the 2 new drives mentioned above - say £120. Or even change the strategy ......

Offsite backups for your critical files. Use something like Mozy (free for first 2 GB) or jungledisk (paid for software, monthly usage fee from Amazon S3...typically a few quid a month for most users).
