MAXimum Protection & Flexibility
NewerTech Guardian MAXimus mini RAID-1 mirror storage solution provides maximum Plug-and-Play "Live Activity" data backup and protection in a space-saving mini footprint. In the pre-configured RAID-1 MAXProtect mode, Guardian MAXimus mini guards against data loss and costly system downtime by writing the same information in real-time to create a "mirrored" copy of 1.0TB of data.
MAXProtect or MAXPerform, Your Choice
For those seeking performance over redundancy, Guardian MAXimus mini can be easily switched via the LCM screen menu to the RAID-0 MAXPerform mode for up to 2.0TB of high speed performance storage. Whatever your preference, Guardian MAXimus mini offers MAXimum performance, flexibility, and reliability for critical data backup
MAXiumum Portability
Guardian MAXimus mini is ready to go wherever your "mobile office" needs take you. Bus-powered (no AC adapter required) and weighing as little as 1.24 pounds, it offers maximum data protection with minimal gear bag bulk. While ultra compact, the Guardian MAXimus mini comes packed with high performance features like dual hard drives or SSDs, data transfer speeds up to 300MB/s, and user conveniences like a front panel LCM screen/control interface for drive and system status monitoring.
Why You Need Guardian MAXimus mini RAID-1
Guardian MAXimus mini is "live activity" backup of financial records, medical files, business projects...any critical data that you simply cannot risk losing. It's always guarding against data loss by writing the same information in real-time to two separate drives for a "mirrored" copy. It also protects you from costly system downtime and data restoring after a single hard drive-equipped system crash. Even daily scheduled software driven data backups can't protect you between your last backup and the moment the hard drive fails. By having a second, "mirrored" copy, all of your data stays backed up and accessible while you replace the failed drive.

Rating: 5/5 Easy-piesy! April 12, 2018 So I see the video and think this will be quick. Then just the trial I had to back out the drive bay screws made me think I would break it. Those screws are tightened way to much! Once the screws were out it was plop, plop, fizz, fizz what a relief it is. I found the area below the unit gets really hot and after a quarter inch spacing it all cooled down. Definitely needs that space! I'm using the MAXImus with two other FW 800 drives and there was no issue with the additional drives. All is well and running great!

Rating: 5/5 Small Form Factor with Great Functionality January 15, 2018 Bought this on a bit of a whim - had a couple of different external drives (Gardian Max and now the Mini) but with the replacement of a couple of drives in laptops, figured it would be a great recycle of these drives. Installs easily and connects quickly to my existing eSATA PCIe card. Probably the only downside is to always remember to eject the drives on shutdown. Bought another for a friend and he's delighted also. Have backed up at least 500MB and found the reliability to be suberp and would be a repeat buyer.

Rating: 5/5 Wonderful little device September 11, 2017 I have bought this kit in order to reuse two HDDs that became freed up after upgrading the data storage in my vintage MBP 17s to SDDs. The GMAX mini kit is super-easy to populate with disks and put to service (you need no more than 2 minutes) and extremely handy and useful, especially when used with FIreWire, which provides enough power for use without the external power supply that also comes with the kit. I had an issue with the LCD in my particular kit. After taking a picture of the display and e-mailing it to the OWC customer service, a replacement kit was briskly sent to me. The service was exemplary: Very understanding and helpful, polite and totally hassle-free. Without exaggeration, this was by far the best customer service that I have experienced in the last 20 years.
