Hi Everyone – I am planning to upgrade my dual boot Ubuntu 16.04LTS/Win 10 system to 18.04LTS /Win10 and would love some opinions. My main drive is a 1TB SSD and my data drives are 2 8TB HDD’s running in RAID1 configuration. I use Ubuntu chiefly for deep learning research with Tensorflow and Pytorch on large(r) Medical Imaging datasets.
In the 16.04LTS build, I split the SSD 60/40 between Windows/Ubuntu, as I anticipated using Windows more. Of course, that’s not the case, and I have yet to crack 250GB use there. I allocated 100GB to Ubuntu root (/) and have only used 30GB so far.
I made a choice to put /home and /linux-swap on the HDD. Obviously, putting /home on the HDD was a terrible mistake, and has hurt performance on the unit. I plan to fix that in the Ubuntu 18.04LTS install.
Plans are to shrink my Windows ntfs partitions down to 450 GB, and expand the Ubuntu ext4 partitions up to 500 GB, leaving 50GB unallocated. I read that it is helpful not to allocate SSD’s fully as it improves performance / error correction /stability. I’m not sure if that only applies to older SSD’s (mine is a 2 yrs old Samsung 960 EVO, so its part of the newer batch), is fantasy/hearsay, or what.
With the Ubuntu 18.04LTS install I will allocate to the SSD like this:
- Dual-boot loaders and Windows 10 – 450 GB
- Ubuntu root : 100 GB (is this too much? Especially if installing anaconda and many packages?)
- Ubuntu home : 350 GB
I’m going to keep linux-swap on the hard-drive because I have 64GB of RAM. I don’t anticipate running out of memory anytime soon, but with 8TB of disk space, might as well put in the swap partition on the hard drive. Anyone have a strong opinion let me know.
Anyone have any disagreement with what I am doing here or any way to do it better? I’m just a hobbyist in Ubuntu so I would love the opinion of someone who has done many installs and ran Ubuntu linux systems a lot to weigh in.
