Hi Benjamin,
I'm not familiar with this disk but you can see the fmstat output that
disk, system event, and zfs-related diagnostics are on overtime about
something and its probably this disk.
You can get further details from fmdump -eV and you will probably
see lots of checksum errors on this disk.
You might review some of the h/w diagnostic recommendations in this wiki:
http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide
I would recommend replacing the disk, soon, or figure out what other
issue might be causing problems for this disk.
Thanks,
Cindy

Dear Forum
I use a KINGSTON SNV125-S2/30GB SSD on a ASUS M3A78-CM Motherboard (AMD SB700
Chipset).
SATA Type (in BIOS) is SATA
Os : SunOS homesvr 5.11 snv_134 i86pc i386 i86pc
When I scrub my pool I got a lot of checksum errors :
NAME STATE READ WRITE CKSUM
rpool DEGRADED 0 0 5
c8d0s0 DEGRADED 0 0 71 too many errors
zpool clear rpool works after a scrub I have again the same situation.

Problem in : zfs://pool=rpool/vdev=f7dad7554a72b3bc

In /var/adm/messages I don't have any abnormal issues.
I can put the SSD also on a other SATA-Port but without success.
My other HDD runs smoothly :
