Hello, I am finding it very difficult to find consistent reliable tutorial to optimize my new SSD drive. There are several out there on the net. Some are old and others at variance with each other. I am using Mint 17.2 on a Kingston Hyper X Savage 240 gigs. I dedicate the full capacity to root / and store my personal data on a Western Digital disk drive.
First time around I used this tutorial.
This insiststed that FSTAB should include noatime but without discard. But after changing scheduler to noop and updating the grub the system would no longer boot.
Later I found this next tutorial which insist I add both noatime AND discard to FSTAB.
I am also noticing that each tutorial seems to edit FSTAB differently. example, the community places noatime before discard. Whereas the following youtube tutorials does it the other way round.

The last time my system was up and running I found that occasionally there was a lag between my keyboard strokes and cursor response times. The author of the first tutorial suggests that the discard in FSTAB is causing CPU overload thus explaining the keyboard lag.
But overall there does not seem to be any consistency to the tutorials offered on the web, leaving me with the painful task of trail and error. I must have reinstalled Mint three times in the past ten days since I fitted the SSD. There is even inconsistency regarding the best file system to use. I have read in some places that the XFS is best for solid state drives. But I have read here that ext4 is best for kernel 3.10 or higher (currently at 3.16 ).
Here is the tutorial which persuaded me to use the XFS file system. But i am going to revert back to ext4.
Today I read that on the official Mint tutorials saying if this command returns zero
And this command returns deadline
Then there is no need to mess with the scheduler or grub. Having said that, the tutorial seems to be two years old.
any pointer, tips or solutions would be much appreciated.
