Add 4 Internal SATA III (6Gbps) ports to a computer through a PCI Express x2 slot. The PEXSAT34RH 4-Port PCI Express 2.0 SATA Controller Card with HyperDuo adds 4 AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections for high-performance hard drives and Solid State Drives (SSDs).

Featuring HyperDuo technology, the SATA card offers SSD auto-tiering which lets you balance the performance advantages of SSD storage with the cost-effectiveness and large capacity of standard hard drives. By combining SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), HyperDuo discreetly works in the background to identify and move frequently accessed files to the faster SSD drive(s) for improved data throughput – up to 80% of SSD performance! (Note: The HyperDuo automatic storage tiering feature is compatible with Windows® XP, Vista, 7 and 8 only)

The PCIe SATA controller card supports Port Multiplier (PM), enabling multiple SATA drives to be connected to one port over a single cable, for a total of 7 drives (Up to 4 drives through PM on one port, and a single drive to the remaining 3 ports). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.

1 out of 5 eggsDo buy it if you own an Acer Veriton

Pros: Pros? Really? Oh ya, it fit in the slot.....

Cons: I own a brand new Acer Veriton M4630G Desktop and I spent hours on the phone with tech support only to be told I needed to install it into a different computer to "test compatability"! I'm sorry but I don't have a testing lab in my home and I am not going to tear into a functioning 7 year old computer to test an item that should work. Back to Newegg it goes and a different brand card is on the way!

5 out of 5 eggsUPDATE to my earlier, recent review

Pros: Again -- all the pros I cited before -- plus a few more. This isn't your $400 RAID controller. It IS a great little hardware controller that seems as fast as you could want, even in an PCI-E 1.x slot. It requires at least two lanes, or x2. If you really think you need something like this, you won't hesitate to put it in an x4, x8 -- or even x16 slot. It will give you JBOD, RAID 0, 1 or 0+1. It also seems great for AHCI configuration and use with drive-pool software on a small server.

Cons: Documentation providing a better understanding for installing the Windows native drivers.

If you want to use the RAID features, your installation may go more smoothly, but what I discovered may not preclude that for AHCI. See "other thoughts."

Other Thoughts: As I said, the controller is supposed to use native Windows AHCI "standard AHCI 1.0 ATA" drivers. Here's what to look out for. You can install the card in its slot, and the native drivers will install perfectly right away. In my situation, though, I had drives formatted under a "casual" SATA implementation not fully compliant with AHCI, and I moved them to the PEXSAT34 unit. Suddenly, my system was reporting "drivers not successfully installed." With some urgency, I inserted Startech's driver disk, and the RAID driver was automatically installed! This may lead to other problems -- which you might diagnose as a "bad SATA port.

If it happens, run the driver update under Device-Manager->Storage controllers ->Driver Details again. Do not allow Windows to grab any driver from the web (first menu option), or it will tell you that the RAID driver you already installed was "best" and already installed. Instead, choose "search for drivers on my computer," browse and indicate the Windows folder on the boot drive, and it will find the native drivers again.

You need AHCI to implement certain proprietary performance features for popular SSDs (like Samsung).

At this point, you have a choice. The "port-multiplier" cable for that feature (allowing up to four drives on one port with singles on the remainder) is hard to find and can cost as much as $50. You can do it that way, and performance won't suffer. But you can also simply add a second card to your system. Not a big price differential to pay, if you don't feel like shopping for the port-multiplier cable. It's almost a breakeven scenario.

5 out of 5 eggsA Nifty Little Controller Card

Pros: From other reviews, this is the slightly more expensive competitor to at least a few other PCI-E cards based on a line of Marvell controller chips. For the price, you get hardware RAID 0, 1 and 0+1. Or -- the board offers up a default of four ACHI ports. It has a port-multiplier capability, so it might host up to seven hard disks.

The native Microsoft drivers only "recognize" the card; it has its own driver set.

Cons: I had heard that the MS drivers were sufficient, so I was a little let down about the need to insert Startech's driver CD and update the drivers. But what hardware card doesn't come with its own drivers?

Other Thoughts: People will have various uses for this product. In my case, I only needed to insert the card in an LGA-775 C2Q system with an NVidia chipset and the nForce SATA controller. Because NVidia was casual about adopting AHCI compliance for their 680i-era boards, delayed procedure calls and interrupts arising from driver conflicts will cause a core of the processor to run continuously at 80+% load. The mere presence of the Startech / Marvell controller resolves the problem.

It also proves capable of saturating an older PCI-E v.1 slot, and the throughput is better than the onboard options. For me, this is an improvement to a small-capacity server of maybe 4 to 6TB, and with a bigger PSU and another such card, one could run eight or more spinners and SSDs.

5 out of 5 eggsBeats MB RAID

Pros: Better performance than Intel "fake" MB RAID (5.9 vs. 4.1) in RAID 1 configuration. The heatsink (in RAID 1 mode) barely gets warm. Driver support is at the BIOS level so no OS software drivers are required. Set up the drive configuration using the BIOS (there's a wizard to help with that) and the RAID array appears as a single drive to Windows. Installing a bootable Win7 on the RAID array is then no problem.

Cons: None really, but the documentation could be improved.

Other Thoughts: Plugs into a PCI express x2, x4, or x16 slot. Has header pins for optional activity indicator LEDs (5 total,1 for each drive plus 1 for all drives).

4 out of 5 eggs

Pros: Provides 4 SATA 3 connections to a P35 motherboard. Although Windows has not been tried, BIOS and Linux Mint fully support this card.

Cons: Will not support a boot drive. Not really a con as it was not expected.

Other Thoughts: Of the 4 drives connected to this card, 4 could be read from and 3 could be written to. The failing drive had to be reformatted before it could be written to.

1 out of 5 eggsRevised review for Linux

Pros: It will mount and read devices reliably, but see below

Cons: Apologies to anyone who acted on my review, here's what I found with more time.
It installs fine, mounts drives OK, but any media it mounts under Linux is only reliable for reading. This applies to hard drives and dvd/cd writers.
I tried to install Ubuntu 12.04 onto it and the install consistently stopped about 1/2 way through with a message about possible bad media. I also tried burning a cd and a dvd connected thru this card and in all cases it reported insufficient space on the empty disc. It will however successfully read media.
Connecting the hard drive and dvd writer I mention above to the native SATA ports on my mobo and repeating the tests resulted in perfect behavior.
Too bad, I really wanted to like this product, now I will RMA.

5 out of 5 eggsWorks with Linux

Pros: 4x SATA 6 for $100, and I got a 20% discount taking it to $80.
Plugged it in and it worked, no messing with drivers.
Works with Linux.

Cons: None after 2 days and some testing

Other Thoughts: I called Startech about this card and they confirmed it works with Linux, and sure enough it actually does.
