        MAXPower USB/eSATA 2x2 Host Adapter for Macs and PCs

        Mac / PC / USB 3.0 / eSATA
        Maximum Versatility
        Designed specifically for OS X 10.8.3 and later, the MAXPower USB/eSATA 2x2 Host Adapter for Macs and PCs utilizes your computers built in xHCI drivers and is the perfect companion card for systems with Apple's current OS. For systems which are running 10.8.2 or earlier, a MAXPower USB/eSATA 2x2 Host Adapter with custom driver 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 requires no drivers and supports hot-plugging, eliminating the need to restart the computer when connecting or disconnecting a USB or SATA device.
        Maximum Power
        The MAXPower USB/eSATA 2x2 Host Adapter maximizes the performance potential of USB 3.0 and 6Gb/s SATA storage devices. The revolutionary, dedicated per-port performance architecture allows each device to run flat out without interference from other attached devices. Each of the two USB 3.0 ports can utilize the UAS (USB Attached SCSI) protocol to transfer data to and from USB storage devices such as hard drives, solid state drives (SSDs) and thumb/flash drives. Faster transfer speeds and lower CPU utilization can be achieved than with the slower queue system of BOT (Bulk Only Transport), which only provides single-task commands - each task must complete before the next begins.

        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 not recommended with this card. Sleep should be disabled when using devices with this card as you may otherwise experience volume ejections when waking from sleep. This issue is not present under Windows. NewerTech has reported a potential xHCI bug to Apple regarding sleep and we hope that Sleep support will exist in the future.

        Rating: 5/5 I installed in an original MacPro 2006 and it worked. October 3, 2014 Out of the box, this worked fine. I installed as per the instructions, plugged in a USB 3.0 drive and it took 2 minutes to move a 6 gigabyte file... from an internal drive to the external drive. The move between two internal drives was about 1 minute. There is one small bug: there is no icon to disconnect the drive so when you pull it, you get the nasty gram..... copying the same folder over USB 2 was about 5 minutes....

        Rating: 5/5 Works with Drobo 5D September 29, 2014 Bought this card for my 2008 Mac Pro because I needed a USB 3.0 card for my Drobo 5D. Works fine, though I had to have Drobo Robotics send me a new (USB 3-compatible USB cable). The performance is better than the original Drobo at Firewire 800.

        I have not tried the eSATA ports, and probably never will. Unfortunately OWC doesn't sell an expansion card with USB 3 only.

        Rating: 5/5 Rock solid! September 8, 2014 After years of using other controllers that were four times the price and having them burn out or be infuriating to install and get working, I tried this controller. WOW! I was up and running in 5 mins. This card even recognised my existing RAID 5 array built with a different controller and mounted it and I was ready to go. Didn't even have to rebuild. How awesome is that? The card is super fast, the NewerTech website is easy to navigate and find product information and updates, the support is brilliant and there's a 3 year warranty. What more do you want? As a professional filmmaker and video editor I have tried cards from HighPoint, Adaptec and ATTO. All expensive and in the case of HighPoint, over-engineered, painful and no customer support. This controller gives me a consistent ~750MB/s using RAID 5 on an 8 drive PROAVIO enclosure - and these are 5 year old SATA III WD RE2's! Not even SATA 6! ADOBE Premiere CC and After Effects CC sing on this card.Never dropping a frame and giving you beautiful smooth playback, even with a fully loaded timeline and all app's open.

        I also have many RAID chassis and arrays like 2 of the OWC RackPro Units and a two drive Mercury Elite and I keep coming back to OWC as they just work like they should. OWC are the only brand that have never failed in my studio. NEVER. Not once. Everything else has, costing me time, money and business. Try this card. You won't regret it.

        Rating: 4/5 Hope they get the OSx boot control soon for this May 24, 2014 Easy to install on my Mac Pro 1.1. And am now running the raid 0 with 4 X SSD 480Gb's. In the beginning, 3 weeks or so it kept loosing the Array from my desktop but now no problems. It is if my Mac has accepted it as one of the family now. If it could at some time in the future be able to handle the OSx boot system then WOW it would be worth double the money for MacPro 1.1 owners like me who just refuse to retire the old architecture after improving it over the years. I also have place most of the applications in the raid array together with movies and music and documents. Very quick. Regards, SFR

        Rating: 5/5 Great addition to Mac Pro August 6, 2013 I added this card and love the additional speed of the 2 eSATA ports. I followed the video instructions you can find on this site, and it was really rather easy to install, even though I am not mechanically inclined. I pair it with the Mercury Pro 4TB external HD to clone my old library, and then use TimeMachine for only my new and current photography.

        Rating: 5/5 Works great, fast transfers, no drivers needed! June 23, 2012 It really works without any drivers in my MacPro 4,1, running Lion. Also works under 10.8 Dev Preview. I also bought the dual drive RAID0 Mercury Pro enclosure and I get around 250MB/se R/W speeds with a pair of older hard dives. I'm very happy with both products. No software to fuss around with. Now I have really fast TimeMachine backups.

        It's showing in the System Profiler as Unknown Controller, but still works. I copied several terabytes of files with no errors and I've run TimeMachine backups for few days just fine.

        Yeah, it doesn't support Port Multiplier, but don't give a product a bad review because you bought the wrong product. It does everything as advertised.

        It's more expensive than cards I use in PCs but the driverless operation is worth the premium. In the past, adding a SATA card to a Mac was always a problem due to poor drivers and drivers being broken with nearly each OSX update.

        Rating: 3/5 Works fine, but doesn't support hot swapping December 7, 2011 This card is great if you have two or fewer external drives you wish to connect, and if you intend to leave them powered on 100% of the time. If you have more than two drives or if you plan to be turning the drives on and off, this card is not for you. If you so much as unmount a connected volume, a reboot will be required to remount it. Had I realized this before purchasing I would have bought something else, as I use eSATA for project-specific drives and off-site backups, meaning I have many drives and swap them out frequently.

        With that said, I have had zero issues with the card aside from this design limitation, so if you do plan to use it with two or fewer always-on drives, this card is certainly a good value.

        Response from OWC, Marketing December 15, 2011 On a Mac, Hot Plug/Hot Swap is supported in OS X 10.7.2 and later. Due to a bug in Apple's AHCI implementation, previous OS versions do not reliably support this feature.

        Rating: 4/5 Great card but BEWARE November 16, 2011 Another review mentions that it does not support hot swap. I would like to also say that if you plan to connect your Drobo S to this device it will work BUT the Drobo Dasboard will not work. I have also had problems with the power saving taking my Drobo offline and then it not connecting until I reboot.

        So overall the card is great. It install very easily and when it's working its fast. Just be aware of what your connecting to it.

        Rating: 2/5 Does NOT support hot-swapping October 21, 2011 Unless the drive you intend to connect will always remain on, from boot to shutdown, this card isn't for you. Whenever you disconnect the external drive connected to this, for whatever reason (like power-saving, multiple drives...), you will have to reboot your Mac/PC for the drive to be recognized again.

        The RAID version supposedly does support hot-swapping.

        Rating: 5/5 Piece of cake significant upgrade September 28, 2011 This PCIe 2-port controller is a terrific upgrade to a stock MacPro. It´s a piece of cake upgrade, done in 10 minutes, and the performance when working with large media files is significantly increased. A no brainer, I should have installed this a long time ago.

        Rating: 4/5 Great card for the price August 5, 2011 I'm not often inclined to write reviews, but I had a hard time finding much information on this card when I considered buying it.

        I already had the non-RAID version of this card, which gave me two eSATA ports, but not with port-multiplier support. I was looking for at least two more ports that I could use with my Cavalry 4 x 1TB enclosure and a future enclosure. Every card that I considered in the <$300 category had a range of limitations. This card appeared to have good throughput, support for drive power management, and RAID was a nice touch for the price.

        Overall, I am quite pleased with it, but I did note some difficulties along the way. I installed this card in my 2009 Mac Pro, then booted up and installed the software on the included disk. After a reboot, that gave me access to the web interface. The web interface is pretty simple, although not always intuitive. After a few stumbles, I got my external enclosure set up with RAID 5. It took about 24 hours to initialize.

        Before I got to that point, I had some difficulties. I am running Lion, so that may be a contributing factor. After I set the web interface to initialize the new array, OS X panicked. On reboot, it panicked again, so that I was unable to boot the machine. Powering down the enclosure fixed that problem. I then went to the Newertech web site and downloaded and installed the latest software. After that, I was able to reboot, turn on the enclosure, and the array proceeded to build without further incident. So, I recommend getting the latest and greatest from Newertech's site before trying to build an array.

        Once the array was built, OS X didn't see it. I thought that I might power off the enclosure and power it back on to get the system to recognize the new drive. That not only didn't work, but it triggered a very loud alarm buzzer that took me several minutes to figure out how to turn off. It turned out that I just needed to reboot to get OS X to see the new drive.

        I initialized it in the Disk Utility and proceeded to copy about 1 TB of stuff to the drive. I didn't run any benchmarks, but the transfer speed was indistinguishable from my internal SATA drives and much, much better than over the USB interface I had previously used.

        Anyway, so far, so good.

        Rating: 5/5 Get it! March 14, 2011 I purchased the NewerTech MAXPower 6G PCIe eSATA RAID Controller card with port multiplier support, and am glad I did. Now I can hook up eSATA drives easily to my 2008 MacPro. Installation is a snap, and no drivers to install. It simply works. If you couple this with the NewerTech Voyager Q- Quad Interface FireWire 800/400/USB 2.0/eSATA - SATA I/II Hard Drive Docking Solution, You have the Easiest Way To Access Data From ANY 2.5" or 3.5" Serial ATA (SATA) Hard Drive Up To 2.0TB!
