[ltp] X200s X60, SSD Samsung 840, trim, kernel, Kubuntu 10.04

[Uwe Brauer]

Hi

I am currently using 2 Laptops a X200s and X61. The first has a SSD
Samsung 840 250 Giga the second the smaller 120 Giga. (Changing to a SSD
was the largest performance boost I have seen in the last years.) Both
laptops I use with Kubuntu 10.04, and the jfs file system.

However I had to compile 3.7 kernel in order to use TRIM for jfs, since
in earlier kernel versions this feature was not supported.

The SSD on the smaller machine failed with a serious error and is now
useless. I wounder if it has to do with the trim operation since I have
read stories about data loss with trim enabled, but then the SSD on the
other machine is fine.

So for the moment I switched back to the old hard disk and I am back
*from* the future, and that is why I will get a new SSD.

I presume I have to upgrade Kubuntu, so the question is: is 14.04 enough
or do I need a more modern kernel even. Is trim save? How often shall I
run it, on every boot, once a week?


Comments are very well come.

Thanks and regards
