I've just completed a new build and I am planning to install and use Linux for the first time in the form of a dual boot with Windows 7 Ultimate & the latest Ubuntu release. I intend to use a 120GB SSD for the OS's and most applications, and to store other data on a 1TB HDD.
After scouring forums on the topic of partitioning drives for this sort of dual boot, I've come up with the following partition scheme, and I am looking for feedback on it:
SSD - 120GB (Samsung 840 EVO):
- [C:] 60GB (NTFS) -> Windows system partition
- [sda1] 20GB (ext4) -> /
- [sda2] 10GB (ext4) -> /home ... (symbolic links to folders for docs, media files, etc moved to HDD)
- [sda3] 10GB (ext4) -> /usr
- ~20GB -> unallocated
HDD - 1TB (Western Digital Caviar Blue)
- [D:] ~700GB (NTFS) -> Windows data partition
- [sdb2] ~300GB (ext4) -> Ubuntu data partition (folders for docs, media files, etc moved from /home on SSD)
- [sdb3] 4GB (ext4) -> /var
- [sdb4] 8GB (ext4) -> /swap (= my 8GB RAM)
- Is this partition scheme reasonable for what I'm trying to do and my usage (usage described below)?
- Are each of the partition sizes reasonable and appropriate?
- Do I need a /boot partition? Am I missing any other advisable partitions or including unnecessary ones?
- I've read conflicting advice about leaving unallocated space on SSDs. Is this necessary? Would I be better off allocating some/all of that space to Windows, or something else?
- Is it a better practice to create a separate NTFS partition on HDD for data sharing between the Windows/Ubuntu than to just access the "Windows data" NTFS partition from Ubuntu?
If I am misunderstanding anything please let me know that too.
Notes about my usage: I will be using Windows 7 for most day-to-day work as well as 3D computer graphics work (applications such as Maya, Unity). I will be using Ubuntu, initially, for some software development work (nothing very intense) and for learning more about Linux in general. I hope to use Ubuntu more and more as time goes on and hope to have some headroom for both OS's.
