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.
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: 4/5 great card for external pcie box May 3, 2015 I put this card in a PCIe expansion box that has a mini-sas back-plane and four SSDs. Once support pointed me to the application I needed to run to get access to the card configuration, I was able to set up a striped set. I get just under 900MB/s read and write from four inferior SSDs. I do not think the card or the bus are the limiting factors, but the SSDs that I am using which are relatively cheap. I have connected the external mini-sas to an eSata docking station and the performance was poor, but I believe that was the docking station, not the card, since that docking station did not perform better connected to another eSata card or to USB3.

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
