2 out of 5 eggsStandard hardware but old firmware and drivers

Pros: Standard implementation of Marvell 88SE91xx which worked for some tasks.

Cons: Really old Marvell firmware. Old drivers on CD. No drivers or firmware on Koutech web site.

Other Thoughts: Buy from another vendor.

5 out of 5 eggsFit my needs nicely

Pros: 6G sata card, bonus mSata slot for boosting I/O just a titch more than a vanilla drive controller

Cons: only 1 sata port.

Other Thoughts: I have not done extensive testing to qualify the performance benefits, but I can say that the device seems stable and does what it sets out to do. Totally worth it if you need a single port 6G sata card and have an mSata drive sitting around.

5 out of 5 eggsWorks great

Pros: Convenient PCI-Express x1 addon card. Works great with mSata SSD and another 6gb/s 2.5" SSD, potentially gives you two more drive ports.

Cons: Maybe another SATA 6gb/s port would have been nice, but really wouldn't make sense for what this is supposed to do.

Other Thoughts: This worked perfect for me the first time I set it up in Windows 7. I have ran it both as the Hybrid drive setup, and the just one and one setup. I didn't run it in RAID 0 mode, since my SSDs speeds seem to differ too much. I currently have it setup with the mSata being the system drive, and a separate 60Gb SSD as the systems temp drive. I moved the windows temp folders, and all library folders, along with some Plex folders to the 2nd SSD to load balance from the system drive. Works great so far and I still have all 4 sata ports on the motherboard for data disks. Turns it into a pretty nice Windows 7 "server" with 4x2TB drives in a mini-ITX case. This is my sandy bridge i5 Plex streaming machine.

1 out of 5 eggsWasted Money

Pros: PCI-Expess 2.0

Cons: I installed this on my new PC to get the most of Rapid Storage but it failed to be recognized. I tried 2 different SSD cards and still it wasn't recognized by Rapid Storage as a cache drive. Don't waste your money on this product.
