SYBA SD-PEX40054 PCI-Express 2.0 x4 SATA III (6.0Gb/s) HyperDuo 4-port RAID Controller Card

Pros: It came in a box

Cons: This card runs the Marvell 88SE9230 which is absolutely pooort for linux. This is the second card running a Marvell chipset, the other being a Rocket 640L with a Marvell 88SE9235.

These cards were both consistently dropping my disks when using mdadm to build raid. I would recommend you spend the extra money if you were purchasing a decent card for storage purposes. Avoid the lower end Marvell chipsets if you can.

Other Thoughts: I purchased the Supermicro AOC-USAS-L8i. This card seems to work beautifully.

Pros: Does what I want it to do. Simple install with prior tech knowledge.

Cons: So far....none.

Other Thoughts: Only complaint I really have is that I recieved my package opened...pay good money and am a constant consumer at nearby. Disappointed I recieved a refurbished device.

Pros: A low cost way for expansion. Works out of the box in linux.

Cons: At this price point, you have to be wiling to work through issues. Or buy the more expensive cards.

SATA port layout is weird, you have to have angled connectors on your cables for two of the ports, and regular connectors for two ports. If you dont, then the cables will interfere with other cards in adjacent slots

Other Thoughts: Bracket was misaligned when the board was mounted, so screwing in the bracket to the back of the case made the card bend a bit and would lose contact to the PCIE slot. Options were to either not screw it into the case, or loosen the mounting screws so the card does not bend. Chose option 1 for now, maybe this weekend I will try aligning the bracket.

Not ideal.

Pros: Price, SSD Caching, SATA 6.0. Hyperduo doesn't have any limitations on capacity. Nice alternative to Intel's SSD caching.

Cons: Performance is lacking for Sata 6.0. Performance is closer to Sata 3.0.

Other Thoughts: I already use SSDs as my boot drive and I wanted something that could boost the performance of my data drive for my games.

I use a WD 1TB Black drive with a 160GB SSD and it does improve my load times on frequently used games and the ones I specify to be cached.

Pros: I bought this to take better advantage of a new Samsung 840 Pro series that didn't work that well on my aging Asus P6T Deluxe V2 (only supports 3Gb/s SATA II).

I was skeptical about add-on card performance based on what I had read, but this card seems to work just fine. I put it in a PCI-E 4x slot.

526 read/502 write according to CrystalDiskMark.

Cons: Slows down boot time.

Other Thoughts: I had to boot Windows and install the provided driver before I could boot while plugged into the card.

Ubuntu booted without any issue.

Pros: i have my 1tb hhd in hyperduo with my 60gbssd ,and it works grate im getting 140 write and 150 read on my Intel controller chip i was getting 80 read/write , i have only used 2 of the sata connectors on the side of the card though , and make sure you put it in a x4 pcie port!

Cons: none so for!

Pros: Cheap... SataIII on 2 ports

Cons: CN1,2 CN5,6 are controlled via jumpers. Traces on board to jumpers are too long, and do not work with SATAIII. Tested with several hard drives. Firmware does not support manual link speed selection. SATA resets occur constantly through CN1,2. CN 3,4 work fine however.

Other Thoughts: Disappointed.. speeds on 2 of the ports are quite decent, but the man.. the first 2 ports are quite failure prone.

Pros: Cheap. Linux supports it.

Cons: Can't trust it.

Other Thoughts: Connected three drives of my raid6 array to it. started rebuilding sixth drive. 20 hour later all three drives reporting serious errors. I looks like I may lose all my data. This controller is not worth the risk. Even if they wish to replace it, how can I risk my data on it?

Pros: very good price for sata 3 controller with 4 ports, using latest chipset from Marvell

Cons: Purchased to extend current MB SATA3 connections. Not able to boot from device, unable to boot in windows 8 or windows 7 with 4 channels hooked up. Was able to boot with 2 channels. Chipset gets extremely hot and will burn you if you touch the tiny heatsink they have mounted on it. Also experienced pauses when using drives attached to this controller with the drivers supplied by the manufacture.

Other Thoughts: If it worked, I would be a happy customer. I will go with another brand and model.

Manufacturer Response:

Dear Customer,

Overheating should not be happening with all 4 ports beening connected to HD.

Please contact our customer service. We would like to find out the following:
-Will the heatsink be hot if only 2 HD are connected?
-Will you experience pauses with just 2 HD connected?

Please check your power supply. Swap the power connectors with other devices in your system.

If it is a defective card, we will replace a new one for you free of charge.

Pros: Bootable without additional drivers (ASUS P8H77-i mb)
SATA III
4 ports (2 internal plus 0/1/2 either internal or external)
FIS Based Port Multiplier
PCI-e x4 for full speed SATA III

Cons: None

Other Thoughts: Choose from 2,3,4 internal ports and 2,1,0 eSata for a total of 4 active ports at any time.

Currently using with a single SSD boot drive allowing 6 MB SATA ports to be used for a 6 drive sata raid array. Future plans to use with an external RAID/JBOD enclosure.
