5 out of 5 eggsworks fine, sata and esata

Pros: As the product specs say, it provides a Port Multiplier with FIS Based Switching, so it's more versatile than many controllers

Cons: My esata cable rests a bit loose in the slot, but connection is continuous at a reasonable thruput.

5 out of 5 eggsDoes what it Should. And Linux Approved !!

Pros: Boots right up with my new Kingston SSDNow V300 Series SV300S37A hooked to it.

This controller in conjunction with the new SSD Seriously increased the speed, performance, and boot times of my Aging 2009 built machine.

Cons: None

Other Thoughts: Could be Sexier, or have more ports. But for the price it does what it should, and seems to do it well.

4 out of 5 eggsDoes what I needed

Pros: I bought 2 of these to get more eSATA ports. Each fits in one PCIe slot. Hot swap works. All 8 ports can run at the same time. Didn't have to use the install disc. Windows 7 installed the Drivers. Not a raid card which I didn't want anyway. The raid options (on the back of the box) are the PEX40057 and 40058.
One other unexpected plus. I have 3 WD (Western Digital) My Book Hme Edition external 1TB hard drives. If anybody has these they know that WD claims they are not hot swap. I DID NOT install the SES driver from WD when I got them several years back. Windows 7 installed the drivers when I plugged them in. I have always had trouble getting the computer to hook up to the drives. Per WD instructions I could only get them to connect by having the computer shut down and restarting it with the drive connected. I thought I would try the new card and see what happened. Amazing. The computer can find the drives. Have to use device manager to scan for hardware changes to fire them up but when I shut the drive down the computer removes the drive without device manager.

Cons: This was not the Syba card I ordered. It was an IOCREST card but the two appear to be identical. I was researching the card # reviews and found the IOCREST on another site with the same part # so I don't know who makes the card. BAD PACKAGING from NEWEGG.The boxes were slightly crushed because they were shipped in a bubble wrap instead of inside a slightly larger box. Should have at least been stamped FRAGILE.But because I had them in my hands I decided I would go ahead and try it. The 4 eggs are for the reasons I just mentioned plus I am still testing the cards.

Other Thoughts: I have a Windows 7 tower, i7 processor and a SATAII (3 Gb/sec) mainboard. I have a second small tower which I built a rack for to hold 6 hard drives. I wanted to be able to run each hard drive separately so I bought a switcher. Also cut a hole in the front of the case to install an extra 92mm fan. Here are the components I used which I bought from Newegg.
ORICO HDD Power Switch HD-PW6102
2 Syba/IOCREST PCIe card SI-PEX40065
6 KINGWIN ESAC-02 R Cable Brackets
6 COBOC SC-SATA3-6FT Round eSATA Cables (Various colors)
(I have other flat cables I bought but they aren't as flexible)
I put the cards in my 2 PCIe slots and used 2 brackets for them (for the 4 internal connectors on the cards. I hooked up the other bracket to 2 ports on the motherboard for a total of 10 ports out the back of the main tower. Used the other 3 brackets in the small tower for 6 ports out the back of it.

All my drives are 7200rpm. After some testing and research I offer the following thoughts for others who are building or buying towers. 5400rpm drives will be slower. Unless you have a high powered computer (SATA III or better, SSD drives, etc.), 6 Gb/sec components may not make a SATA II machine any faster. I have seen burst speeds around 300 MB/sec but sustained data rates of about 80 MB/sec when transfering large files. (I do a lot of home video MPG and AVI files) This agrees with a lot of posts I have read. This burst also translates to less than 3 Gb/sec. The computer/hard drive memory fills up with the burst and drops back to the sustained rates I am seeing. About 1 GB/min sustained transfer speed for large files. I am replacing a 3 Gb/sec card with this 6 Gb/sec card and it may be somewhat faster with my SATA II board. But compared to USB2 speeds my eSATA is still 4 times faster (sustained rates). An empty hard drive will have faster transfer speeds than an almost full one. I defragment my drives every 100GB or so. 1TB or larger drives can take some time to defragment so doing it often helps save time.

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.

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
