Pros: Excellent! Gives you four SATA ports. Needed a SATA controller for a FreeNAS build. Detected my Addonics SATA to CF adapter (ADSACFB) perfectly.

Cons: Overpriced. Should have just purchased an inexpensive motherboard for the same amount.

Pros: Inexpensive. Worked in a newer motherboard.

Cons: Would not work well on an old Intel D850GB motherboard. Would not boot from any motherboard I used. Had originally planned on using it for a FreeNAS OS disk.

Overall Review: Might not be compatible with older hardware. Spend a little extra for a SATA to CF adapter from another manufacturer.

Pros: Ultra DMA mode 4 bootable CF card. Works perfectly in an Addonics SATA CF adapter (ADSACFB). Fast enough for my FreeNAS box.

Cons: N/A
