1 out of 5 eggsWhat's the point? UPDATED

Pros: Sorry for the repeat - NEWEGG makes it impossible to edit your reviews!

Can't beat the price.

With the proper BIOS, chipset, and driver updates, you should be able to get OK utilization of the 2 PCI lanes this card provides. More than enough speed for any spinning disk drives. However, we maxed out at a disappointing 700MB/s write and (interestingly enough) 620GB/s read using 4 Samsung 850 PRO SSDs in RAID0.

Cons: This is an exceedingly poor physical board design:

SYBA used jumpers to redirect SATA data streams between internal and external ports. This essentially adds 16 more potential points of failure and encourages the consumer to rub their grubby fingers all over them. Ideally, these signals should be switch in silicon. But at the very least, SYBA should have used 4 pole switches to preclude contamination and just make it easier on their customer.

The two fixed internal SATA connectors are mounted edge-wise so connecting cables is easy but they do not support locking cables and it is very easy to dislodge one. We resorted to hot glue, I'm ashamed to say, to secure these.

The two internal connectors associated with the jumpered ports DO support locking SATA cables but come straight out of the PCB so regular SATA cables will interfere with an adjacent PCIe slot - you'll need to use cables with a 90 degree connector. Make sure you get ones that bend in the right direction.

Our application is for all internal SATA ports only so the jumpers were pretty annoying to me.

The paper documentation that comes in the box is pretty bad in my opinion. Marketing this kind of product to consumers, there should have been very clear diagrams (ie. pictures) of all jumpers and connectors. You can take a microscope to the board and figure out what they meant but your basic tech consumer shouldn't have to. Also, at the very end of this document, they direct you to a third party driver download site for drivers. This I find unconscionable. The drivers are available on the SYBA site but it takes a little exploring to find them. And by the way, you will need these - don't run this board on the default Microsoft drivers.

SYBA (or possibly Marvell) did something funny with the drive activity signals at J9 and J10. In all other controllers I have dealt with and with the motherboards that support injection from a PCI controller, this signal is an open collector transistor that pulls low on disk activity and can be used in a "wired-OR" configuration with other disk controllers. The two boards we are evaluating are either both broken or simply don't work that way. In any case we were unsuccessful getting the disk activity signal to work with our ASUS motherboard.

Finally, one of the two boards we were evaluating started locking up the disk subsystems after a few days testing. This is a lab environment and it is entirely possible we blew this up ourselves - that's why we buy two for evaluation :)

Other Thoughts: It should be noted that our target system is an aging ASUS Z8NA-D6 running Windows Server 2012 R2 (which is not officially supported by SYBA). We are testing with Samsung 850 PRO SSDs and Western Digital Black spinning media drives. The Z8NA-D6 is only PCI express 2.0 but if we can max out the PCI lanes it should have a successful second life as a file server and VM host.

We were disappointed in our initial results using Storage Spaces (OS level striping/tiering) and so we went back and tested the card using the HyperDuo with RAID0 across four Samsung 850 PRO SSDs. Surprisingly, this made less than 2% difference. We still got 700/620GB/s write/read throughput. We are still not sure why read speeds are slower.

UPDATED SUMMARY: If 600-700GB/s is an acceptable ceiling, you gotta have cheap, and you don't mind working for it, this might be your card.

Next up on our evaluation: SUPERMICRO AOC-SAS2LP-MV8 - still pending.

Manufacturer Response:

2 out of 5 eggsWhat's the point?

Pros: Can't beat the price.

And with the proper BIOS, chipset, and driver updates, you should be able to get good utilization of the 2 PCI lanes this card provides. More than enough for spinning disk drives though you will easily hit the 1GB/s ceiling with 4 good SSDs.

Cons: This is an exceedingly poor physical board design:

SYBA used jumpers to redirect SATA data streams between internal and external ports. This essentially adds 16 more potential points of failure and encourages the consumer to rub their grubby fingers all over them. Ideally, these signals should be switch in silicon.

Make sure you get ones that bend in the right direction.

Our application is for all internal SATA ports only so the jumpers were pretty annoying to me. A board with locking SFF-8087 to SATA (like StarTech's PEXSAT34SFF) is far more attractive in my opinion despite the additional cost.

The paper documentation that comes in the box is pretty bad in my opinion. Marketing this kind of product to consumers, there should have been very clear diagrams (ie. pictures) of all jumpers and connectors. You can take a microscope to the board and figure out what they meant but your basic tech consumer shouldn't have to.

The Z8NA-D6 is only PCI express 2.0 but if we can max out the PCI lanes it should have a successful second life as a file server and VM host.

We did no serious testing on the RAID or Tiering (HyperDuo) capabilities of this card. We were only interested in its raw JBOD capabilities. But as we were able to closely approach the max PCIe 2 transfer rates using software raid, I suspect the built in RAID will perform as well.

SUMMARY: I'm not sure this board has a purpose any more. Yes, an ambitious person can take 3-4 SSDs and this card and bang out a 1GB/s drive array. But why? If your mobo is reasonably recent, it has PCIe 3.0 and there are faster, bootable options (like M.2). If your mobo is older PCIe 2 then your BIOS likely won't support booting from this controller. That just leaves what we are doing: trying to build out secondary disk capacity on an aging PCIe 2.0 system. In that case, more PCIe lanes per slot are better (this board only utilizes 2 on an x4 slot).

1 out of 5 eggsHow could you mess this up?

Pros: Cheap
Good if AND only if you want to extend Sata II (not III) ports

Cons: Falsely advertised.
Not Sata III speeds.

Other Thoughts: Dear Syba and Marvell. How could you possible have messed this up? Do you know how easy it is to advertise the correct speeds for each individual item? (Hint: It's pretty easy). The reason I ask this is due to the fact that this product does NOT support SATA III (6.0Gb/s) due to the fact that each SATA port onboard is connected to a PCI-e X1 (2.5Gb/s) lane (yeah, that's right. It seems when I installed it into a computer, the bios on the card itself reads it as PCI-e 2.5Gb/s on a PCI-e 2.0 lane, which makes no sense given that I only had an x16 lane in use and my motherboard has 3 x16 PCI-e 2.0 lanes, while the chipset supports up to x36 PCI-e lanes in use). It's not as if I have a bad SSD either, since it's the 256GB Samsung 850 Pro - which is arguably one of the fastest SATA III SSD's on the market. When advertising you need to advertise the theoretical speeds of each INDIVIDUAL port on the item. The III in SATA III denotes it is the 3rd revision of SATA and thus can support up to 6Gb/s PER LANE. Whats funny is when using this card, I got worse speeds than the already falsely advertised Marvell SATA III controller on my motherboard (which supports 5Gb/s although it was advertised as Sata 6Gb/s).

Manufacturer Response:

Dear Customer,

This device is advertised correctly as it can reach SATAIII speeds utilizing a PCI-E x1 lane.

We understand that it's difficult to understand the complexity of PCI-Express lanes. However as indicated from multiple reputable sources a PCI-E v2.0 x1 lane can, and does reach SATAIII speeds if you utilize bi-directional bandwidth, which this card does.

A PCI-E v1.0 x1 lane is only capable of 2.5Gb/s. You need to properly identify the correct version of your PCI-E lanes as this determines the speeds you are able to obtain.

Do note that, yes, this cards ports all do share the single lane (x1). When multiple devices are accessed at once you will bottleneck the single lane. However when accessing one device at a time you can achieve SATAIII speeds with the controller.

If you need any more information or help understanding PCI-E lanes please feel free to contact our tech support team which is more than willing to help you.

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

5 out of 5 eggs

Pros: SSD boot drive plus 3 HDDs connected and recognised by Windows 7 Home Premium, no problems.

No need to install any Marvell drivers. Upon first bootup Windows loaded OK, automatically installed some drivers and requested a Restart. After restarting the computer everything works fine. If you're using Linux then maybe you need Marvell drivers.

If you're not using RAID or HyperDuo then there's no need for installing the Marvell Utility software.

If you want HyperDuo or RAID then you can access the setup for that during bootup by Ctrl + M. Only install the Marvell software if you want to play with the settings when Windows is already running.

I used the HyperDuo in the past and it worked well, but now using SSD on its own for Windows and other drives for data.

Quick access to all drives.

Max. Sequential Read/Write MB/sec. on SSD (ATTO): 540 / 535

On the SYBA website product page you can click on the "Question" tab and ask tech support to clarify anything you need to know. They are very helpful in their replies.

Cons: Install can be confusing and frustrating unless you follow instructions EXACTLY. And, the instructions are not always clear to the uninitiated.

A series of jumpers allows you to choose between using all 4 internal SATA ports or using 2 internal plus 2 external SATA ports. Jumper pin layout on the card is opposite to jumper pin layout normally used on motherboards. Usually, on a 3-pin jumper the pins are numbered from left-to-right, 1-2-3. However, on this controller card, while the jumpers themselves are clearly labelled, the pins on each jumper are not labelled. It turns out that the pin numbering sequence on these jumpers from left-to-right is 3-2-1. i discovered after connecting 4 drives to the internal ports that only 2 drives were recognised. This led to moving all the jumpers to adjacent pins which activated the other 2 internal ports, and all drives were then recognised. In other words, the jumpers were preset for using 2 internal plus 2 external ports by default. If that's mentioned in the instructions i failed to see it.

The internal SATA ports are somewhat delicate so be careful when connecting and disconnecting SATA cables. If you need industrial strength connectors buy a $400 controller card, not a $40 card!

This card adds 5 to 10 seconds to the bootup time.

*Important: If you're going to set up the Hyper-Duo feature you must do a fresh install of Windows. Be sure to save all wanted data onto a different drive before proceeding.

Other Thoughts: My Windows boot drive and three data drives were all connected to the SATA II ports on my ASUS P6TD Deluxe motherboard (circa 2009). Everything worked OK except that the SSD Sequential Read speed was limited to about 280MB/sec. So, i installed the SYBA SD-PEX40054 controller card. After fiddling around with the card's jumpers i got all 4 internal ports working. Now, the SSD reaches Sequential Read speed of 540MB/sec. In regular use, the faster speed will probably only be noticed when copying very large files or loading game levels with large graphics textures. Still, it's nice to update an older SATA II board with speedier SATA III, and you gain 4 extra ports!

3 out of 5 eggs

Pros: You can get this thing to work.

Cons: Poor design needs more thought on connector layout , poor documentation actually no documentation came with, does not work as advertised per Syba tech support. If using it as a boot and only a boot may work but not when you use it as a boot and data storage device. Hangs on boot so takes many times to boot. save your money and upgrade the motherboard better results I'm sure and you can upgrade SATA and USB at the same time which actually would cut cost. Ended up putting the SATA III disk back onto my SATA II from motherboard to boot. When it did boot correctly which happened a few times it would boot very fast.

Other Thoughts: If you do regular builds maybe but if you only do builds very seldom may not be for you. Took about a week to install with new install of os as well and trying to solve the issues. MOBO was Rampage II with the card in third 16 video slot.

Manufacturer Response:

Dear Customer,

We apologize for your dissatisfaction with the quality of this controller card.

Please note that when booting from this card a reinstall/repair of the OS is necessary.

Our tech support team is more than happy to provide any information you may need when determining the compatibility and specification of a device.

Our tech support team may also assist you with installing and configuring this device for your system.

5 out of 5 eggsGreat card for the price

Pros: Great card for the price. Put this in an older gigabyte board along with a samsung 850 pro and it has been working flawlessly.

Cons: The only thing that I dont really like is the 2 back sata connectors because they do not lock. The cable tends to slide off easily but I just make sure they are seated correctly before I close the case.

I was well aware of this issue before I bought it. for me it is not a deal breaker just thought I would throw it out there.

2 out of 5 eggsavoid this card for Linux use

Pros: seems well made,
Syba support very responsive
This is likely a Marvel problem not Syba

Cons: Near identical problems as another reviewer. Under high load with Centos7 variety of controller problems ending in all 4 ports shutting down.
Contacted Syba they indicated there are no newer firmware upgrades.

Web searching suggests other have this issue but no resolution.

Other Thoughts: As I've tossed box etc not too sure what my options are.

Manufacturer Response:

Dear Customer,

We apologize for your dissatisfaction with the quality of this controller card.

Its rare for many Marvell controllers to operate at peak performance outside of Windows OS. If possible we would suggest that most users stick with a Silicon Image or ASMedia chipset.

Our tech support team is more than happy to provide any information you may need when

determining the compatibility and specification of a device.

5 out of 5 eggsSYBA SD-PEX40054 PCI-Express 2.0

Pros: Just installed this controller extra PCI-E x8 port that was available on my Gigabyte GA-EP45-UD3P mobo socket 775, and it works great. My mobo is only SATAII, so I wanted to take an advantage of SATAIII speeds with my Muschkin 120GB SSD. For less than 50 dollars my SSD speed doubled from about avg. 250mb/s to 513/531mb/s.

Cons: none.

Other Thoughts: Based on Based on Marvell 88SE9230 Chipset, if you have PCI-E 2.0 available on your motherboard this chipset supports speeds up to 10GB/s.

Note: If you have older board like mine, check with motherboard mfg. website to make sure you have an extra 2.0 slot, otherwise the speed will be similar to SATAII.
On the ATTO benchmark it looks very impressive over 500mb/s r/w but Gigabyte bios loads so slow. It takes about 15-17 sec before the drive even starts to load, after that its super fast.

4 out of 5 eggsSATA III PCI-e X4 adapter

Pros: Adapter works great with SSD. Using the PCI-e V2.0 slot, an OCZ Vertex 460 achieves 492 MB/s read and 475 MB/s write speeds, which is very close to the rated speed and much faster than my onboard SATA II connection.

Unfortunately, I had to use a PCI-e X16 video card slot, which is version 2.0 since the X8 slot is only version 1.0. When used on a PCI-e V1.0, it only achieved 345 MB/s write and 290 MB/s write (onboard SATA II was 259 MB/s read and 246 MB/s write).

Good price for the features, although I have not tried the RAID or Cache yet. The main reason for purchasing this card over other cards using PCI-e X1 is to maximize a SSD.

Cons: None, other than the IOPS changed from 48,000 for read and write using SATA II compared to 33,000 read and 62,000 write using the PCI-e X16 slot.

Other Thoughts: If you only have PCI-e V1.0, the card will yield only marginal improvements over SATA II. All testing was done using Anvil Storage Utilities v1.1.0
