Number of disks and size?

[Lasse]

Hi, We are about to setup ms sql 2008 in a new server machine.
There are today 2 user defined databases of size 30GB and 2GB that will
migrate to 2008 from sql 2005
The disks are in hp "EVA".

We are thinking of using this setup, does this seem appropriate in terms of
getting best performance? is the disk size enough?
C:\ Windows
72GB (existing)
D:\ System Databases (TempDB) 100G
E:\ User Defined Databases 100GB
G:\ Transaction Logs 100GB
H:\ Backups, Batch Processing, Full Text Catalogs 200GB

Thanks,
Lasse
