[clug] Suggestions on Partitions and Mounts for Solid State Disk Drive

[George at Clug]

    Hi,

I have been reviewing partitions and mounts for a 500 GB Solid State
Disk Drive. 

If you are into this kind of thing, please reply with your comments. I
would be particularly interested in comments about partition sizing. I
usually take the lazy way out and format a single '/' partition, so I
am not sure about allocating sizes.

If you have any tips on OS configuration for SSD's, I would be
interested in learning.

My final solution may end up being a combination of a SSD and a HD due
to a) I have a 2TB HD, b) cheaper for great space, c) I could leave
out noatime.

Below are my current settings for a single 500 GB Solid State Disk
Drive laptop on which I would support one or more virtual machines
using qemu-kvm.
