5 out of 5 eggsFirst cheap 4X SATA card that works

Pros: It worked right out of the box. Plug and play with no issues with Win7 64 bit on a Asrock X79 EXtreme 7 MB. Ditto on an ASRock Z170 MB with Win 10 64 bit.

Cons: I am not using it for RAID but others seem to have made it work well for that - just not something I needed.

Other Thoughts: Works best with the INTEL Standard, SATA AHCI controller. I would advise not installing the Marvel drivers. I have been looking for a long time for a 4X SATA card that does not cost an arm and a leg that is reliable and this one is! Using just for JBOD. Speed was not an issue for me either but it is within 80% what my MB SATA III controllers do.

1 out of 5 eggsSyba Offers Terrible Products...With Even Worse Tech Support

Pros: The card worked for 2 months. Syba doesn't deserve 1 egg.

Cons: This card drops hard drives constantly. Two of the four drives I have plugged into this card disappear as soon as I attempt to access. I have checked these drives on my other computer---and the drives appear fine, they can be accessed without issues.

Other Thoughts: I sent 2 emails to Syba, ..."Please provide me with updated Win7 and Win10 drivers (I plan to migrate to Win10 if this card has the proper drivers). If you don't have any updated drivers to send (other than what was on the CD) then please provide me with an RMA #."

I've not heard anything back from the Syba company. They make cheap products that don't work very long...with a hollow 3 year warranty. Based on my experience with them, it will be impossible to get a replacement.

5 out of 5 eggsEasy setup & configuration.

Pros: Can be set for SCSI, Raid or a combination of both.
Drivers are easy to set-up for card recognition

Cons: none

Other Thoughts: I'd recommend to friends who don't have SATAIII 6Gb transfer as an upgrade.

3 out of 5 eggsJury is still out!

Pros: Price.

Card was recognized by Windows 7 and, in spite of not being able to load the card drivers, it works with all drives. If you connect a DVD drive to this card be sure and go in the properties and select "cache mode" or you will not be able to write to the DVD. This little item was not mentioned in the manual.

I gave it a 3 because of the driver problem.

Cons: Got error message every time I tried to install the drivers. I notified Tech Support and they directed me to the latest drivers and instruction...........None of which helped. Two days ago I requested additional help. As yet there has been no response!

Manual could stand a lot of improvement.

The supplied drivers disk was useless. Windows 7 kept telling me that the supplied drivers would not work with the installed card.

Other Thoughts: I expected better. You get what you pay for!

5 out of 5 eggsPainless Installation on Win10 x64!

Pros: Installed on my HP Prodesk running Win10 x64 boot/reboot and everything is running perfectly. Windows installed the correct driver with no issues or further configuration required.

Cons: None to date.

Other Thoughts: I am using this card to free up SATA ports onboard and connect several eSATA drives using 2 SATA to eSATA dual port brackets. Eventually I intend to upgrade the individual external drives into another unit and take advantage of the FIS port replication.

4 out of 5 eggsSo far so good

Pros: Ordered 3 of these. 1 arrived DOA with capacitor rolling around inside the bag. Newegg was great and processed the RMA quickly and shipped out a new one.

I have 2 of these loaded so far and running about a week on my Linux Mint 17.3 computer.
I have 4 x 8TB Seagate Archive HDD's on card 1
I have 1 x 8TB Seagate Archive HDD and 1's on 1x 1TB WD Caviar Black HDD on card 2
I have the 5x 8TB (across 2 cards) HDDs configured using software MDADM RAID5.

both cards were immediately recognized by the system. No additional driver download was required.
All drives were immediately recognized by linux
All formatting and RAID build went seamless
Testing Read & Write speeds between SSD + 5x8TB built RAID5 using these cards + 8x6TB built RAID6 using MoBo SATA3 ports... All read & writes were comparable and acceptable between the 8TB archive drives built array and the 6TB regular 7200 rpm HDD's built array.

Very pleased so far with the performance of these cards.

I called the vendor's apps team before purchasing these cards as I was comparing with the many different options they had available. There were very capable and answered all my questions.

Cons: minus 1 egg for the DOA

Other Thoughts: Yes would recommend these cards to others

I will try and update further after a couple of months of usage.

2 out of 5 eggsMuch harder to install than it should have been

Pros: Able to add more drives

Cons: After much fussing around got it to work. Still gets error message in Hard Disk Sentinel: "The status of the hard disk is unknown. The current disk controller driver does not provide full access to the disk itself to read all details. Please check if there is an updated driver available". I'm a little concerned about not being able to check on the health of drives connected on this card.

Other Thoughts: Using Windows 7 64 bit. Seems like from the other comments it should have worked. I'll keep fooling around with it. Maybe try a different slot. I hate hardware that's sketchy....

4 out of 5 eggsEasy to set up. No Hardware RAID, but can set it up through windows.

Pros: Can set up RAID0 through windows no problem. Easy to set up. Plug and Play.

Cons: Fragile connectors, a little too fragile. Not able to use hardware RAID. Was hoping to move my SSD Raid0 set up from the on board SATA2 ports.

Other Thoughts: Its good if you want to boot off a single drive through the card.
