Cost of SLC is considerably more than an MLC version, which I don't think is justified for an L2ARC.
This server is going to be used to host VMs via iSCSI in a lab/test system. We are going to use dedup with the table stored on SSD. The strategy I am looking at is using slower 7200 RPM disks to hold rarely used data, and then get the "working" set running from SSDs. > >We got the broadcom based nic. I think it was the default.
