I put the OS and all programs on by C: drive, and I have a 120GB SSD.
All data is stored on a different HD/Partition.
If you put programs such as Office on the second hard drive, it could complicate system imaging backup and restoring. (Registry entries are stored on C: )
If you ever have to restore the C: partition, you may also have to restore the HD partition where programs such as Office are installed to keep everything in sync.
180GB is a lot of space (to me), and I don't think you will have space issues installing Office on C:.
Maybe this: ?
- Install the OS and all the programs you want on C:
- Check how much space is used/free.
- If space permits, install "other" programs to C:
- If you don't have enough space, put "other" programs on a separate partition on the HD - not the same partition as your data
