If anybody uses SSD for rpool more than half-year, can you post SMART
information about HostWrites attribute?
I want to see how SSD wear for system disk purposes.
I'd be happy to, exactly what commands shall I run?
Hm. I'm experimenting with OpenSolaris in virtual machine now.

Let's suppose you rename a file or directory.
/tank/widgets/a/rel2049_773.13-4/somefile.txt

For the l2arc you want iops pure an simple. For this I think the Intel SSDs are
still king.
The slog however has a gotcha, you want a iops, but also you want something
that doesn't say it's done writing until the write is safely nonvolitile. The
intel drives fail in this regard. So far I'm

ZFS does not use segmap.
The ZFS ARC (Adaptive Replacement Cache) will consume what's
available, memory-wise, based on the workload. There's an upper
limit if zfs_arc_max has not been set, but I forget what it is.
If other memory consumers (applications, other kernel subsystems)
