I have an Intel X25-M 80GB SSD.
For optimum performance, I need to block align the SSD device, but I

If I run the format -> fdisk it allows me to partition based on a
cylinder, but I don't think that is sufficient enough.
Can someone tell me how they block aligned an SSD device for use in l2arc.
Thanks,

(a) what makes you think you need to do block alignment for an L2ARC
usage (particularly if you give the entire device to ZFS)?
(b) what makes you think that even if (a) is needed, that ZFS will
respect 4k block boundaries? That is, why do you think that ZFS would
put any effort into doing block alignment with its L2ARC writes?
