installing on a 80gb SSD, need help aligning partitions, etc
Hello
For my new server, I've ordered an Intel 80GB X25-M G2 SSD to be used as a system drive. For various reasons, I intent to stick with UFS2 for it (ZFS is going to be used on other disks in the system) and I intend to use GPT partitioning. Can anyone point me to any instructions regarding setting up proper sector sizes, properly aligning partitions to blocks and other such things? Windows 7 and Win2008 R2 both do this automagically, but other OSes seem to require a fair bit of manual work still. |

What leads you to believe that you need to align partitions to blocks?

The fact that most, if not all SSD's suffer if this is not done. It causes excessive disk access during IO, because instead of reading off or writing to 1 block (aligned), it has to read or write to 2 (misaligned). This causes a performance hit in random IO and causes increased wear on the SSD during write operations, shortening it's lifetime.
