5 out of 5 eggsGood SATA Controller

Pros: 8 ports and it works!!

I have bought lots of IDE and SATA controllers and they wouldn't work. They would boot the onboard bios, and see the drives then when windows boots up, they go into hiding. THIS CARD IS A GOOD WORKING CARD!!!! NO ISSUES!!!!

Cons: NO RAID?

Other Thoughts: NO RAID?

4 out of 5 eggsInteresting device, works great, but a little confusing

Pros: his is a 4 port SATA III device with a port multiplier for each port. This gives you one additional port per connection to total 8 devices that can be attached. Lower cost per port compared to a full blown 8 port controller i.e. RAID SATA/SAS controller. Simple enough to install under LINUX no driver required. This has taken an older motherboard that had only SATA II support and breathed new life into it.

Cons: Confusing when your used to seeing all of your disks attached be displayed during the BIOS load Some performance lost due to the port multiplier. Documentation should state that you will not see all devices in the BIOS. Made me wonder if the controllers were not jumper-ed correctly. The description for this controller should state something in plain English how this works. It should state that the controller is a 4 port device and it uses the port multiplier technology to increase it to 8 ports. There would be less of the reviews stating this is a poor product. Also this is packaged in the IOCrest name. I have purchased SYBA product before and new the logo, I thought I had received the wrong product and in fact these are one in the same.

Other Thoughts: I have installed 2 of these in a small 16 * 6TB disk storage server, running LINUX software RAID 6. For the cost compared to purchasing a controller that supports RAID and 16 or more ports you would pay 2 1/2 to 4 times this. You get your monies worth when using this for a low performance storage. Only time will tell if there will be issues. But from what I have read if you know what you are doing with these controllers you should not have any problems.

5 out of 5 eggsPerfect for the average storage junkie

Pros: Simple installation process. No extra power requirement. Simply plug into a PCI-e x2 or x16 and install the corresponding driver that comes on a mini cd in the package.

No problems so far and all drives work flawlessly.

Cons: None

Other Thoughts: Only the first 4 sata ports will work out of the box. You need to install the driver in order to get all ports working.

The driver cd contains a .txt file that explains what driver needs to be installed depending on your OS.

Currently I have mine running on windows 7 64bit and can confirm it works like it should.

1 out of 5 eggsinaccessible Marvell BIOS

Pros: none.

Cons: The manual states one must enter "Marvell BIOS Setup" in order to create a RAID array. It states the boot screen will display similar to "Press <CTRL>+<M> to enter BIOS Setup or <Space> to continue"

My boot screen simply displays "Press <Space to continue". Attempting to press CTRL M at that time does not open the Marvell BIOS and even if it did the boot screen only shows 4 out of the 5 connected drives. All jumps are set to "1-2" but that hardly matters as I can't enter the Marvell BIOS screen anyway.

Though I don't believe it makes a difference at this point, I've installed the latest Marvell drivers and nothing changed. I'd attach an image of the boot screen but this interface doesn't appear to be capable of that.

If I can't enter the Marvell BIOS, I can't create a RAID array. If I can't create a RAID array, this product is essentially a paperweight. Though it's not even a good paperweight because it's too light.

Manufacturer Response:

1 out of 5 eggsAlmost works

Pros: good price; number of ports

Cons: reproducibly produces kernel panic under load

Other Thoughts: 1. Arrived promptly as always from newegg
2. Look good, package nice
3. Installed, attached 5 disk drices, recognized by OS (Ubuntu 14,04.1LTS 3.13.0-32-generic kernel), see all of them in OS (do not see some on BIOS post, but that iss ok).
4. Hot swap works as advertized.
5. Created zpool succesfully, 5x2T WD Green
6. Attempt to rsync ~1/2T of data; kernel panic after ~20G; reset; repeated this 5 times, reliably produces kernel panic under load in few min.
7. Removed card; replaced with old SATA I controller, same disks attached,
8. Now it works, did same rsync twice, no problem (but slow as expected).

Conclusion - good card but not for me.

4 out of 5 eggsWindows 7 help

Pros: 8 sata III channels
Tiny type of DVD with the drivers under the white carton in the box. Driver can be found on the internet.
Work with PCIE_16x

Cons: My -1 egg:
Lack of information in case of little trouble with the installation.
I wish it had a Wizard Setup installation like Asmedian or the JBMicron. Not sure the average buyer knows enough for a manual installation.

I don't know if the product is new or unpopular ,but when I Google I couldn't find any review or problem with solution post for the installation of the driver. Many Newegg review says 4 out of 8 channels don't work and Newegg link is the first in the Google list.
I had the same problem.

Not really a con but it got me confused when installing:
In the tiny DVD there is a lot of driver , but only 1 driver is needed in the Marvell folder. The others are problably for other type of controller cards like PCIE to USB.

Other Thoughts: The following instruction is made out of my own personnal experience with the hardware SI-PEX40071 and Windows7. Also my first sata controller. Follow at your discretion.

If in the "control panel>devices manager" you dont have the "storage controllers" image (a C with dash in it), you didnt install the driver.
To install the driver on Windows 7 , after installing the hardware. You need to know that Windows will install is own drivers that he possess. And it might be your motherboard controller driver. Put the tiny DVD in the DVD drive for the driver. Else get the driver from the Syba webpage.

Go in device manager of Windows and check the IDE ATA/ATAPI controllers section. You might have some information in double. ATA channel are ok.
Right click the others for the "Update drive software".
Choose the Browse my computer and take the path of the DVD folder with the drivers.
For a 64 bit OS:
Marvell\92XX\Windows Vista_2008_7_8\ amd64
the 32 bit OS:
Marvell\92XX\Windows Vista_2008_7_8\ i386

You cant access the file.Windows will take care of searching in that folder.
If you chose the wrong driver to update.Windows will let you know he will do nothing and keep driver already install.

When you chose the right one. Windows will show you the Marvell driver 92XX to install.
After installing it will make the Storage controllers section and remove some Ata channel from the IDE ATA/ATAPI controllers section.

When you let hardware connected to the not functioning channel on the controller, the auto-play will pop up in the screen.
Possible after restart some hardware disappear in Windows Explorer after fully installing your connections hardware on the controller card. My hard drive and blu-ray
needed drivers again and change of letter paths. After second restart everything was stable for me. For SSD or storage that boot an OS, you might need to check the Bios setup and make some research.

I wish I had some kind of similar instructions when I did my installation. Sorry for the not professional writing and lack of precision since I wrote it after my success and I dont know how to revert. This is the minimum to make the 8 channel work on Windows7. For Raid and similar stuff you will need find other instructions.

2 out of 5 eggsHalf working

Pros: 8 Ports

Cons: Only half the ports worked. I installed the drivers from the cd no problem, but whenever I plugged in a hard drive it would BSOD. I then noticed there was a windows update for the marvel chip set, installed that, BSOD went away but the drives are still not recognized. The documentation is way too limited. Debating whether to try to continue to make it work or return it and get a cheaper 4 port card.

Manufacturer Response:

Dear Customer,

We are sorry to hear about the problems that you have been having with this device.

Please check that the jumper settings are correct for the device so that the SATA ports are active.

Also check that you have the latest Marvell drivers for this chipset.

If you have already ensured that the card jumper setting are correct and the latest drivers are installed we would advise you to complete our RMA form for a replacement device.

For any other help please contact Syba support.

3 out of 5 eggsonly half works

Pros: a fairly quick boot process. It post fairly quickly. Since it does not have to go through a RAID post. it seems to have reasonable speed.

Cons: This is an 8 port device, but I have not been able to get my system (Windows 7 pro) to recognize 4 ports. It seems to be dead, but does not flag any errors on post. I had wanted these 4 ports for expansion later, but for now the first 4 ports fill my need for now. I would have given this 5 stars if all 8 ports worked.

Manufacturer Response:

Dear Customer,

We apologize for the issues that you have been having with this card.

Perhaps the Jumper configuration is not properly set for all eight active ports.

Also check that the drivers were installed by the system properly. You may need to manually

install the drivers for the card.

For any other help please contact Syba support.

3 out of 5 eggsDoes SI-PEX40071 Support 2 Working Port Multiplier Devices ???

Pros: Can work with my old 2005 Dell Dimension 4700 & now "upgrade" it to have 10 HD ports (including the 2 on the Dell). Can use this old computer as a "storage server" which is plenty fast enough to do that. Playback media files on a home network.

Cons: If this works, READ BELOW, then this is a MAJOR+ "Pro" -not a "con"... 5 Stars IF THIS CAN Work... ??? Anyone???

Well, I see the manufacturer does review these posts, so maybe we can get an answer before I use this card for the purpose of connecting 2 different port multiplier devices...

I'm looking for an add-on card that can support 2 separate port multiplier channels (one each) for 2 separate port multiplier devices to connect to its own port multiplier. I understand this SI-PEX40071 uses a dual chipset to get to 8 ports, so it ALSO MIGHT Support & Have 2 Separate Working Port Multipliers too???

Can I run this card with 2 separate port multiplier devices -one on each 2x4-port chipset that also might have its own port multiplier of 2 in total???

I have the 4 port HyperDuo, but it only supports ONE port multiplier on the card through ONE of the 4 ports at a time -one device supporting port multipliers can be attached to this HyperDuo. I would need 2 HyperDuo cards to work, but MAYBE the SI-PEX40071 Supports & Has 2 Working Port Multipliers ???

Manufacturer Response:

Dear Customer,

This device does not support more than one(1) port multiplier. This is due to a limitation from

the Marvell chipset.

Even though this card uses dual Marvell chipsets it will only be recognized by the system as using

one which will still only allow one port multiplier.

Currently the SiliconImage chipset is what you are looking for as it will support multiple port

multipliers on one card.

Thank you for purchasing one of our products, and for leaving us your valuable feedback.

5 out of 5 eggsYey 8 more ports

Pros: Very High Speed, Average of 150 MB/s to 200 MB/s on SATA III hard drives.

Cons: Will not work with other third party SATA controllers like ASMedia or another Marvell Controllers.

Other Thoughts: I found the installation of this card confusing as my BIOS only shows 3 out the 8 hard drives, that really got me concerned, wish they would have listed that on the manual. But upon loading its dedicated driver in Windows 7 64 bit all 8 hard drives were seen in Windows by not while posting in BIOS. I guess thats normal. I did try to get it working with a second PCIe card with an ASMedia controller but they would just fight and it would not post. Tried with my motherboards onboard Marvell controller and the same thing, they would fight for domination. So Im out 2 Sata ports on my ASMedia Card and 2 more SATA ports on my motherboard, this card picks them all up, when you buy please take this into account. All my Intel based SATA ports work just fine. Im very happy with this card as it works with no issues, transfer speeds are fast and its been solid for the last month.
I would definitely recommend it, just do some research first.

I have 8 3TB hard drives on this card in case you were wondering.

Since I applied this to A PCIe X16 slot now my graphics runs a PCIe 3.0 x8 . This is a limitation of the Intel Chipset, if your motherboards has the tools to correct this then good otherwise if you game this might concern you, go with Intel Enthusiast platform.
