MAXPower RAID mini-SAS 6G-1e1i
One port external & one port internal mini-SAS 6Gb/s RAID controller card

MAXPower RAID mini-SAS 6G

Unleash your Performance Potential with up to 4800MB/s Data Transfer Rates!
Eliminate the SATA drive bus speed limit! Adding the MAXPower RAID mini-SAS 6G-1e1i to your Mac or PC provides a SAS/SATA 6G (6.0Gb/s) drive bus with up to twice the data transfer speed, regardless  of your computer's built-in SATA 3G (3.0Gb/s) data bus. Utilizing the MAXPower's RAID processor, you can maximize your total performance up to 4800MB/s in RAID 0 mode or achieve the perfect balance of performance and protection in RAID 5 mode.

This feature-rich, high-value mass storage controller card is an ideal solution for those working with multiple high-speed HD video streams and/or anyone seeking high performance daily IT operation and back-up for an SMB. With mini-SAS, there's no loss of throughput as it provides full data transfer of four drives through one connection.

More Lanes = Faster Speed
Mini-SAS is like traffic moving on 4 lanes on the highway instead of just 1 lane.  Mini-SAS offers more "lanes" for data to travel, providing the ability to reach higher speeds.  Just like the SATA/eSATA interface, mini-SAS offers the convenience of a one cable connection. However, in a multi-drive SATA/eSATA solution which, only offers one lane for four drives to send/receive data on, mini-SAS provides four separate lanes so each drive can deliver its maximum capable data transfer rate. Now you can use one or more mini-SAS equipped external storage enclosures like the OWC Mercury Rack Pro for greater speed, protection, or both compared to single channel multi-drive eSATA RAID or eSATA Port Multiplier solutions.

Why mini-SAS Chart

Internal & External Ports
The MAXPower RAID mini-SAS 6G-1e1i card features one external mini-SAS port and one internal mini-SAS port to connect and RAID external enclosures and internal drives.
Automatic Device Passthrough
The MAXPower RAID mini-SAS 6G-1e1i has an automatic passthrough feature that will pass any connected drive to the OS without needing to initialize it via the Web Manager. With other RAID cards, the card's RAID system takes immediate control of the drive rendering it unusable until you configure it. With the MAXPower RAID mini-SAS 6G-1e1i card, as soon as an unformatted drive is inserted, it is immediately available for formatting with no need to release it from the RAID system. This feature lets the card act like a non-RAID card, which is helpful when you just want to swap single non-RAIDed drives in and out quickly.

Spare Pool Support
The MAXPower RAID mini-SAS 6G-1e1i card can be configured to set aside extra drives in a "spare pool". If a drive should fail in RAID 1, 5, 10 or 50 modes, a drive from the spare pool is instantly implemented so a rebuild can start immediately, minimizing the risk of data loss.

NewerTech RAID Manager Offers Easy Array Management
This easy to use, web browser-based utility automatically logs all events that occur on the MAXPower RAID mini-SAS 6G-1e1i from minor issues like inconsistent data to major issues like a failed drive. The built-in scheduling system offers quick convenience in setting up RAID arrays, managing connected drives, viewing storage health status, and reviewing information about your connected storage. See RAID Manager tab below for specific details.
What Is RAID?
RAID stands for Redundant Array of Independent Drives. This means taking multiple matching drives and arranging them together to achieve a large storage space, high speed, data protection, or any combination of the three. The MAXPower RAID mini-SAS 6G-1e1i controller card supports RAID 0, 1, 5, 10 and 50 levels as well as supporting JBOD (SPAN and individual drive modes).

JBOD (Independent Drives)
Each drive appears independently with each drive presenting its stated capacity for use.
JBOD (SPAN)
Combines capacity of two or more drives of the same size without any RAID data distribution scheme into one logical desktop volume. Will also combine the capacity of varying size drives based on the lowest capacity drive in the set.
RAID 0 (Stripe)
Data is split into blocks over two or more drives at the same time for high speed and large capacity. This is the ideal RAID setting for demanding video production/editing.
RAID 1 (Mirror)
Data is written at the same time to two drives to provide a high level of data safety and redundancy.
RAID 5 (Stripe with Parity)
Data is Striped (RAID 0) while incorporating redundancy over three or more drives for the best combination of speed, capacity, and redundancy.
RAID 10 (1+0)
Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives for fast redundancy.
RAID 50 (5+0)
Data is striped (RAID 0) over two RAID 5 sets to provide increased speed while maintaining redundancy.

Does the MAXPower mini-SAS 6G card support tape devices? The MAXPower mini-SAS 6G card was optimized to RAID HDD's and SSD's and does not support tape devices.
Which Connecting Cable Should You Choose? When using Passive/passthrough mini-SAS storage solutions equipped with "6G" 6Gb/s (SATA 3.0 Revision) drives, we strongly recommend only using connecting cables of 1 meter or shorter length due to the increased signal integrity requirements of 6G drives. Active storage solutions such as SAS expander systems equipped with 6G drives can utilize mini-SAS connecting cables up to 10 meters in length. This is dependent upon the external enclosure.
Boot Camp Compatibility Please note that running the MAXPower RAID mini-SAS 6G card in Windows XP is only supported on a PC and is not supported via Boot Camp on a Mac.  Windows Vista and 7 are fully compatible with the MAXPower RAID mini-SAS 6G card via Boot Camp on a Mac.

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.

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.

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.
