PROS: Works great with Windows 8.1. I anticipated problems but there were none.
CONS: Slightly annoying on startup because the program loads before the BIOS and displays an option to configure it. It delays startup of Windows by a few seconds. To me, having the extra two drives is worth the wait.
I bought this card when I was in need of more SSD hard drive space. Rather than replace my 32GB SSD, I just bought another with the intent of striping the two drives together using this SIL3132 card. My MicroATX PC had one extra PCIe 1x port available, so it was a perfect fit. Well I got everything installed in a brand new high end machine, and this RAID-0 drive has read/write speeds of 149MB/52MB! So slow! The standalone SSD's could read 480 MB/s. I was expecting maybe a 25-50% gain, but I have a 66% loss. Any suggestions? Please reply!
I'm using this card on a WHS 2011 system and I'm very happy with it. WHs 2011 is built on 2008R2, but what works one, doesn't necessarily work on the other. This card works well for a 2 port controller.
