Another follow-up-myself, just to document my tests: |

Repartitioned the ssd today, as Ted Ts'o describes at: |

Ok, this might not be necessary/helpful anymore for the Intel X25-M G2 |
| 28 |
... but anyway, I had to get rid of those unnecessary XP-partitions |
| 29 |
anyway ;-) |

Wanted to do a secure erase with hdderase (on the ultimate boot cd), |
| 32 |
didn't detect my ssd even with AHCI off in bios and legacy mode ... also |
| 33 |
"hdparm --security-erase" didn't work. I decided to skip that and wait |
| 34 |
for TRIM in 2.6.33 or later. |

I wonder if /var and /home should be on the ssd or not. It is very nice |
| 37 |
to have a silent machine ... but maybe this does more harm than good. |

So far the ssd is nice to have. I am looking forward to try it inside my |
| 40 |
thinkpad someday ... |
