MAXPower USB/eSATA 2x2 Host Adapter for OS X 10.6 - 10.8.2

Mac / USB 3.0 / eSATA
Maximum Versatility
Designed specifically for OS X 10.6 - 10.8.2, the MAXPower USB/eSATA 2x2 Host Adapter for OS X 10.6 - 10.8.2 comes with a custom built driver and is the perfect companion card for systems which still require a legacy OS. For systems which are running 10.8.3 or later the driverless MAXPower USB/eSATA 2x2 Host Adapter is also available.
Maximum Integration
The power of USB 3.0 and SATA 6G high-speed interfaces are brought together on a single PCIe 2.0 card with the MAXPower USB/eSATA 2x2 host adapter. With both high-speed USB 3.0 and 6Gb/s eSATA connectivity, the MAXPower USB/eSATA host adapter provides connections to the latest technology. This highly integrated I/O card saves valuable PCIe slots while adding the throughput desired for demanding applications like video editing, audio mixing, and photography.
Maximum Performance
The MAXPower USB/eSATA 2x2 host adapter provides two eSATA ports that are compatible with the latest 6G technology such as SSDs, allowing for speeds up to 6Gb/s. It is fully compatible with SATA I (1.5G), SATA II (3G) and USB 2.0 and supports legacy devices, hubs, and external optical drives. Simple to integrate and operate, it supports hot-plugging, eliminating the need to restart the computer when connecting or disconnecting a USB or SATA device.
Maximum Efficiency
Since each USB and eSATA port commands a dedicated PCIe lane, card-level throughput of up to 2,000MB/s can be achieved, up to 500MB/s per each port. And the eSATA ports support port multiplication, allowing you to connect multiple eSATA devices through a single port.

For applications in servers or other specialized computers where space is limited, the MAXPower USB/eSATA 2x2 features a removable bracket design to fit into low profiles machines. The small size accommodates most Mac and PC workstations. Using less power than most PCIe cards, the MAXPower has been designed to run faster and cooler than other cards on the market.

All MAXPower products are designed with superior quality components for long life reliability and the USB/eSATA 2x2 card is no exception. Every component from the card to the cables has been tested to ensure optimum performance.


Important Note: Apple OS X Sleep is not supported with this card. Sleep should be disabled when using devices with this card. The computer's screen will turn off, but the computer will not actually enter a sleep state with the card installed.

Rating: 5/5 Does what it's supposed to April 9, 2022 Installing it was a breeze: open up the MacPro 5,1, remove the retaining bar for PCI cards, plug the card in, put back the retaining bar, close up the MacPro, reattach cables, fire it up, and try a USB3 memory stick—it mounted on the desktop and I was able to transfer files much faster than using the built-in USB2 or FireWire800 ports. So now I can hook up an 8TB external USB3 drive instead of my much-slower Drobo FW800.

Rating: 5/5 Works in Catalina and Monterey. PCIe x2 slot, NOT x1 February 17, 2022 PCI Vendor ID 0x1B21 Device ID 0x1060 Works over Thunderbolt 1 & 3 in an Echo Express SE I, which fortunately has a 8x slot with 4 lanes attached. Important to note that this WILL NOT FIT IN A x1 SLOT. It has an additional 4 pins (22 total, although 1 and 2 are combined) on the card edge for Lane 1 TX/RX, making this a x2 card. I don't know of any x2 slots anywhere, so you're going to NEED A x4 SLOT wherever this goes. They appear to be actually hooked up as it shows as a x2 card in FreeBSD 12 when I put it in my PC (which is how I discovered it wouldn't fit in an x1 slot). I've got a x1 card (a SIL3132 that doesn't work on recent macOS anymore, necessitating this new one) that I compared and measured against. 11mm past the notch vs 7mm.

I would recommend this item to a friend! This review is from NewerTech MAXPower eSATA 6G Pro PCIe Expansion Card with 2 x eSATA 6G Ports.

Response from OWC, Support February 18, 2022 Thank you so much for that recommendation. PCIe cards are a great way to add more functionality and usability to a computer whether it's by adding more ports, storage, or providing some other way to enhance a device. Glad to hear that this could be of help to you and let us know if you ever need any other solutions. :)

Rating: 5/5 Works as advertised December 6, 2021 It's really great to be able to update my 2009 Mac Pro to cope with certain modern demands like connecting multiple modern USB devices that demand a lot of resources, such as those I have that carry high resolution audio in both directions, along with MIDI and other data in just a single cable. This PCIe device solved that problem. It was easy to install and works great.

However, when my Mac Pro goes to sleep it powers down this USB 3.1 card and so the External Drive is improperly ejected. This isn't a problem with the original USB connections.

Reviewer: Hardbop
Rating: 5/5 Great product April 2, 2019 My mid-2012 MacPro is great except it lacks newer connection technologies like USB-C. FW800 at .8 gb/s was not cutting it. But this card has added eSATA speed of 6 gb/s, which compares favorably with USB 3.1/gen 2 (10 gb/s). It's especially fast if used with an SSD drive like OWC's Mercury Elite Mini that has an eSATA interface.

Rating: 5/5 It works! February 27, 2017 After mistakenly purchasing the wrong card for my Mac Pro tower I replaced the card with this one. After installing the card, my Mac's screen went grey and went into recovery mode, just like it had with the previous card. After switching the SATA 6 card with my SSD on it to the top slot in the PCIe bus and installing this card underneath it, the Mac booted quickly and the card was put into immediate use with my new Mercury Elite QX2 raid drive. I let it churn in the background for a week to backup all four of my drives in my computer using the eSATA connection. Thanks to the great tech support people OWC for helping through all this and their gracious consideration in exchanging the previous card. I would recommend this card to anyone with a previous tower Mac who wants the higher speed busses offered with this card.

Rating: 4/5 Works but... February 1, 2017 I installed this board in my Mac Pro 4,1 running 10.6.8 with no issues. I have no idea how fast it is on my external ssd, but it works fine, What I found is that it does NOT work through a usb3 hub, powered or not. I noticed on one hub description on Amazon that pcie usb3 ports are not compatible with their hubs, and I presume that applies to any usb3 hub. I went to the system profiler in OS X and found that this board is seen as a SCSI board and each port has its own SCSI address. That probably explains why usb3 devices cannot be daisy-chained from this pcie board. I guess it's a clever way to pry a high speed usb3 port onto an old system, but it does have a down side. I do not know if other pcie USB3 boards that are compatible with OSX 10.8.5 and above use the same trick since usb3 is native to those OS versions, if not the hardware. I have not checked to see if the same SCSI trick is is used for the SATA ports, that is, whether they access the system through scsi. Probably not, since SATA is native to the Mac Pro hardware.
