4 out of 5 eggsDriver issues, eventually solved

Pros: Properly runs at 6G SATA speeds, eSATA ports work. Does support Port Multipliers (eventually)
Fits in a 1x PCI-e slot.
Includes Low Profile bracket, which I needed for my HP MicroServer.
Hot plug works on all ports.
All four ports are usable!! Not like some cards where you can use internal or external ports only.

Cons: Major driver issues with Windows 8. This is a long one but if you run into this issue this post will save you 2 hours of headaches.

The controller on the board is a Marvell 88SE9215 controller (as it says on the back of the box). I confirmed this in Windows by using the Hardware IDs which indeed were DEV_9215.

My challenge came when I tried to hook up an external eSATA enclosure with port multiplier (a SansDigital TR4M+BNC). It didn’t work. In fact it wouldn’t even see one drive correctly. So I figured the first issue was the driver. Windows 8 detected it as a "standard SATA AHCI controller” which I doubted supported PMs.

I tried valiantly to get it to detect a better driver to no avail. I downloaded the latest Windows 8 Marvell driver from the Syba website, as well as Intel's site (search marvell sata driver). Both drivers were identical.

But no matter what I did, it said that there was no driver there for my device. I eventually figured out that it’s because the INF file doesn’t have the proper PCI\VEN_1B4B&DEV_9215 string for this card! It does have strings for the 9220 and 9230, which are the same chips essentially. Even going to the Syba website and downloading the drivers for this exact card gave me the same driver set with the same problem - the INF is missing the proper IDs for the chip.

So I figured easy enough, I’ll just edit the INF file. But now it won’t install because the hash of the INF file has changed and the driver signing digital signature check fails.

So I had to figure out how to remove driver signing in Windows 8, which is extremely cumbersome. Search Google for it; you have to reboot into the Windows 8 advanced startup and disable driver signing for that one boot to install the driver.

The driver is now installed, and the port multiplier sees all the drives. However I am running with an unsigned driver, which is obviously not ideal, and the Marvell Storage Utility does not see the controller (so I can't use it for troubleshooting).

I have written to Syba so hopefully this issue can be addressed.
Removed an Egg for wasting two hours of my time on a wild goose chase.

4 out of 5 eggsmeh, better then what I was getting before

Pros: Faster then using 3gb/s

Cons: My Speed test results:
Max 307.5MB/sec
Ave 256.7MB/s
Min 210.2MB/s

Using a drive that claims :

Max 560MB/s
Sequential 525MB/s

Still unable to install drive due to my computer saying drive software does not need to be updated, not sure whether or not that has anything to do with it.

1 out of 5 eggsDOA

Pros: Good idea!

Cons: DOA - didn't show up in device manager. When I plugged in the eSata cable, the computer could only see one of the HD's from my Icy Dock. Icy Dock works fine through USB, but much slower.

Other Thoughts: Too bad - this looked promising

Manufacturer Response:

Dear Customer,

Our cards are made with State-of-the-art SMT machine. DOA is not likely to happen.

Please contact our technical support team. We would love to go through the driver installation with you one more time. Most likely, the wrong driver was installed for the card.

Do you have chance to test the internal SATA ports?

When contact us, please provide the following:
1. Windows version
2. How many PCI-e slot on your motherboard
3. A link on Internet to your Icy Dock specifications

Our technical support team is available to help 9am-5pm M-F. Feel free to contact us during those business hours at
