For everyone, real world write tests (with synthetic writes), notice most drives able to write hundreds of TiB some approaching a PiB -- http://www.xtremesystems.org/forums/showthread.php?271063-SSD-Write-Endurance-25nm-Vs-34nm
Adam - If you partition free space (under provision) the modern drives will wear level themselves quite well. Like Seth, we run a lot of Intel 320's, including our pfSense boxes with great success. We've been burned by cheap SSDs in the past though, for example we had a SanDisk unit that appeared to have a good 10x write-amplification in a pfSense box and died very prematurely. On the plus side pfSense continued to function properly without a hard disk indefinitely (though unmanageable).
