A word of caution on the Silicon Image 3124. I have tested out a two extremely cheap card using the si3124 driver on b134 and OIb147. One card was PCI, the other PCI-X. I found that both are unusable until the driver is updated. Large'ish file transfers, say over 1GB would lock up the machine and cause a kernel panic. Investigation revealed it was si3124. The driver is in serious need of an update, at least in the builds mentioned above. It's possible that a firmware update on the card would help, but I never had time to explore that option. If a device using the si3124 driver works great for you in a L2ARC role after extensive testing, then by all means use it, I just wanted to pass along my experience.
