Take the following example, where i'm using files but it's the same with real devices.
This will tolerate 1 to 2 device failures.

If two devices fail from one top level vdev (mirror-N) you will lose data.

I would strongly suggest using odd number of disks and keeping one hot spare in pool.
In your configuration, get one more disk if you really love your data.

Code:

[root@gimmick ~]# ls -dl /zones/test/disk*
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk0
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk1
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk2
-rw------T   1 root     root     104857600 Jun 16 02:48 /zones/test/disk3
[root@gimmick ~]# 

[root@gimmick ~]# zpool status testpool

NAME

       test-filter-module - A tester for Courier::Filter modules

VERSION

       0.18

SYNOPSIS

       test-filter-module module [options] message [+control ...] [...]

DESCRIPTION

       This is a tester for Courier::Filter modules.  It sets up the specified Courier::Filter::Module::module filter module, using any supplied
       options, and then queries the filter module for consideration of the given message file and zero or more control files.	More than one
       message/control files tuple may also be specified, in which case the filter module is applied to each message and its respective control
       file(s).  Filter module options must be specified in the format -option=expr, where expr may be any valid Perl expression.

EXAMPLES

       test-filter-module DNSBL -zones='["bl.foo.org", "bl.bar.org"]' test.rfc2822 +test.control
	   Applies the Courier::Filter::Module::DNSBL filter module to the test.rfc2822/test.control message/control file tuple (taking the
	   sending machine's IP address from the control file), using the blacklist DNS zones "bl.foo.org" and "bl.bar.org".
