    2 out of 5 eggs Pex40040

    Pros: It works
    Easy to install

    Cons: Benchmarks are showing that if I run my internal ssd off this card the ssd is slower than if I plug the ssd into a sata 2 port on the mobo....bummer

    Bottom Line: I suppose that if you just want to add a port for a hdd the card would be fine but that's not what I bought it for.

    5 out of 5 eggs Good add-on card for the price

    Pros: - Cheap Price

    - Works as expected

    Cons: None

    Bottom Line: I needed an additional internal SATA connection as my motherboard only had 4 and they were being used. I purchased this card and didn't even have to install an additional driver for it (I am running Windows 2008 R2 for my server). Also the external eSATA port is a great bonus for the price. Great add-on card!

    5 out of 5 eggs Great Controller For The Price

    Pros: Faster boot times and performance. Win 7 disk performance went from 5.9 to 7.2 !!

    Cons: None so far!

    Bottom Line: I believe some of the troubles people have installing this is the drivers and bios (MB) settings. I installed this controller first, rebooted, and let windows 7 find it first. Of course, it installed a generic driver which does not take advantage of what the controller can do. After the install, I went to the website and downloaded the latest driver for my OS. The disk provided DID NOT WORK. saved it and went to update driver but told windows to let me choose the device. At that point, I went to the folder where I unzipped the driver. This is where it let me install the correct driver. Now, instead of it showing up as a standard sata controller, it appears as a Marvell 92XX SATA 6G Controller. At that point, I shut down, moved sata drives over to the new controller, boot to MB bios, and set boot device to be my boot drive again. This works for AHCI mode which I am using. The controller also is designed for booting from SSD's

    5 out of 5 eggs SO HAPPY-So fast

    Pros: Made my sata II board lighting fast with my ssd! after having an X58m Msi with my i7-950 for a year (work build) i recently looked into the specs of my board,and realized i was somewhat bottlenecked running a sataIII ssd,on a sataII board..Installed super fast with no issues and no messing with bios!

    Cons: none

    Bottom Line: I even bought this thing USED from the main online auction site,and this thing works minty fresh brand new! very pleased!!!!

    4 out of 5 eggs Suppliment to Review Below - Avoid if you need to boot to Optical

    Pros: Installed in the DVR/Server mentioned below and learned some new info to share. I don't feel guilty about the double review because I am reviewing it in two environments doing two different jobs.

    Compatibility and speed are as stellar as before, but must now be qualified.

    Cons: Booting to an attached DVD-ROM FAILED if the motherboard SATA ports were set to the all-important AHCI mode.

    Booting to an attached DVD worked with the mobo RAID enabled, but the BIOS ROM on this card prevented the motherboard's RAID BIOS from running, essentially making the onboard SATA ports useless. Then again, that is a fault of the motherboard and not this card. If you need multiple boot ROMS to load, get a server motherboard or roll the dice like I did and risk losing one.

    Booting to an attached DVD worked fine if the mobo SATA was set to compatibility/IDE, but that is slower, does not support hot-swapping (vital for a RAID), and is far from optimal all around.

    I have submitted a support ticket to Syba about the boot issue but don't have high hopes.

    -1 egg for forcing me to abandon hardware RAID (fakeRAID actually) for software RAID and take the DVD out of the boot sequence, thus necessitating the use of a USB DVD if I need to boot to an optical disk.

    Bottom Line: Before installing an OS or even creating a partition, I used the live XP on Hiren's 15.1 to test a Corsair Force GT 60GB SSD first on this card, then on a motherboard SATA3 port in AHCI mode using HDD-Tune. On the motherboard port the throughput was consistently 30-35% higher, access time was lower (negligibly, though), and CPU usage was slightly lower. This is clearly a limitation of the PCIe 1x interface. It's way better than SATAII (see my other review), but you get what you pay for.

    Moral of the story: ALWAYS use motherboard SATA3 ports for speed-intensive disks or SSD's. The performance difference is substantial. ONLY use this card or one like it if a motherboard SATA3 port isn't available/doesn't exist and upgrading your motherboard isn't an option.

    4 out of 5 eggs So far so good

    Pros: Running in VMware ESXi host, using passthrough to allocate the device to a VM guest (running CentOS). All works well

    Cons: None so far

    Bottom Line: Would love to know if this controller supports drives > 2TB. I can't find it in any documentation, and no response on the forums on SYBA web site.

    2 out of 5 eggs SYBA SY-PEX40040 PCI-Express 2.0 SATA III (6.0Gb/s) Controller Card

    Pros: Cheap, port multiplyer support, speeds not less than expected

    Cons: Cannot boot PC IF there is a drive plugged in to this controller, tech support is no help

    Bottom Line: I had no intention of booting FROM this controller but, if there is a drive plugged in to this controller when booting my computer, not even the controller on the motherboard will boot a drive, with boot order properly set. Tech support insisted this is not a bootable controller card after repeated explanations that I am not booting this controller. Windows 7 had no problem recognizing two drives in the TT black duet on this controller but it can only be turned on after the system drive boots. Windows XP recognizes two drives sometimes. Other times the asmedia controller has to be disabled and re-enabled before it sees the two drives.
    Should have gotten the Rosewell...

    1 out of 5 eggs More Blue Screens

    Pros: Showed a significant performance increase over my motherboard SATA-II ports when talking to my Sandisk Ultra120 SSD which is also SATA-II. Gain was about 25% on sequential reads, 10% on sequential writes, and almost 3X on random reads & writes with queuing enabled (qd 32).

    Cons: First problem was during driver install. It went as normal, but when it was just about complete, the system froze. This is with a Gigabyte GA-MA790FXT-UD5P running XP home.

    On restart however, the system installed the driver without even throwing up the plug and pray wizard, and Device Manager showed all was well.

    I then ran benchmarks and saw the improved performance over my motherboard SATA.

    However, over the next few hours of using the computer, I experienced two random blue screens. I then removed the card and the system is back to being stable, as it was before this fiasco.

    Bottom Line: The reason I purchased this card for this system is that I got a SATA-II SSD for my computer, but the performance using my motherboard SATA ports was well short of what SATA-II is capable of, roughly 170MB/S reads and 70MB/S writes. Curiously, the same drive in another system (Intel chipset) ran 210/150, and likewise, a different SATA-II SSD in my system ran 220/140. So it seemed this particular SSD model was just not a good match for this particular motherboard SATA-II.

    So I got this card to see if I couldn't get more reasonable speeds out of the SSD, knowing full well it would still be limited to SATA-II speeds since that's all the drive can do. Unfortunately, it blue screens on me.

    I purchased two of these cards, one for the above mentioned Gigabyte board and the other for a Dell Dimension 4700. Since I got somewhat different results between the two, I wrote separate reviews. However, the bottom line is the same, both are useless to me, and both are being RMA'ed.

    5 out of 5 eggs Just works

    Pros: Cheap.

    Cons: None.

    Bottom Line: I got this to run a Samsung SSD on my Intel X58 motherboard. It works. Getting over 450MB/s on a Samsung 830 SSD. Completely worth it.

    5 out of 5 eggs One Of A Kind

    Pros: Fast Response
    Fast Loading Bios
    AHCI v1.3
    *Best SSD Solution for any board bottle-necking bandwidth due to a lack of SATA III controllers.
    **Excellent upgrade for any older SATA I or II motherboards.
    ***I searched over 30 similar PCIE cards from many vendors across North America. I contacted many manufactures asking technical support if they offered an O/S bootable controller with AHCI support. At the present time I could only find TWO for under $100 which had all the features packed in this puppy. I was specifically looking for a card with an AHCI enabled bios for communicating TRIM to a solid state drive.(The main feature most competitors lacked) This card had it all and has not let me down.

    Cons: None regarding the cards performance & functions.
    Manufacture error in placement of bracket screws on board pulls card away from socket. (It's a minor flaw which can be easily overcome in less than 30sec)

    Bottom Line: Despite the negativity surrounding this card I was prepared in advance to deal with the issues reported by the other reviewers. Here is some help if you're interested in this model or the (SY-PEX40039=2 internal SATA). First off the screws which connect the mounting bracket to the cards board are slightly off causing the card to pop out of the socket. Simple Fix: No bending or machining required. Remove one screw holding the circuit board to the bracket. The one farthest away from the socket point. Takes less than 30 seconds. Card sits perfectly & secure. Most BSOD are due to incorrect driver installations. You must F6(insert drivers)during a fresh O/S install if you don't want to experience the BSOD. Installing the driver on a windows ready system should be done on the motherboards SATA controllers before plugging in the card. Then boot at least once with a non-boot drive connected before switching to an O/S partition. Also copy the driver from system32 to WoW64.
