MaxPower eSATA 6G PCIe 2.0 RAID Capable Controller Card

What is eSATA 6Gb/s?
eSATA stands for External Serial Advanced Technology Attachment. eSATA 6Gb/s (600MB/s) for external storage devices.

What is RAID?
RAID stands for Redundant Array of Independent Drives. Put simply, this means taking multiple matching drives and arranging them together to achieve large storage space, speed, data protection, or any combination of the three. The MAXPower eSATA 6G RAID PCIe 2.0 Controller Card supports RAID 0, 1, 5, and 10 levels as well as supporting JBOD (SPAN and individual drive modes). You can learn more about RAID modes at this link here.
Port Multiplier Support
In addition to supporting any single or dual eSATA enclosure, the NewerTech MAXPower 6G PCIe eSATA RAID Capable Controller Card supports port multiplier enclosures to connect up to 5 drives into a single eSATA port. By supporting port multiplier enclosures, the NewerTech MAXPower 6G PCIe eSATA RAID can provide massive storage and increased data protection by connecting enough drives for protective RAID arrays such as RAID 1,10, & 5.
NewerTech RAID Web Management Utility
The NewerTech RAID Web Management Utility is an easy-to-use web browser-based application to set up RAID arrays, manage connected drives, view storage health status, and view information about the connected storage devices. (See screenshot)
Future Ready Yet Fully Backward Compatible
The NewerTech MAXPower eSATA 6G PCIe 2.0 Controller Card is like a "performance assurance policy" as conventional hard disk drives and SSDs migrate to the SATA 6Gb/s standard. Installing the card now offers immediate speeds gains while making a Mac Pro or PC future ready for even greater speed gains. Like all good upgrades, the card doesn't leave the past behind. The NewerTech MAXPower eSATA 6G PCIe 2.0 Controller Card is fully backward compatible with PCIe 1.0 slots as well as previous generations of SATA 1.5Gb/s and 3Gb/s drives.
Adds Faster Than Factory Interface To Mac Pros
From faster backups and file transfers to high-end Audio/Video editing, connecting an eSATA interface equipped device to the NewerTech MAXPower eSATA 6G PCIe 2.0 RAID Capable Controller Card can take data transfer performance to an entirely new level. Optimally compatible with Mac Pro models and PCs with an available PCIe 2.0 slot, the NewerTech MAXPower eSATA 6G PCIe 2.0 RAID Capable Controller Card works with ANY eSATA interfaced equipped external hard drive to deliver significantly faster data transfer rates over the fastest factory equipped Mac Pro interface of FireWire 800.

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.

I would recommend this item to a friend!

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!

I would recommend this item to a friend!
