I bought two of these units to link them into a RAID 1-0 in my Imac 27 inch desktop.
The Apple OS was all I needed to do that.
I found an article online that detailed the procedure from womb to tomb. Well almost. From initializing it with zeroes (not needed but recommended for easier recovery) to setting it up. Took me several tries as the OS level was different than the article and therefore had to improvise / test . But in the end it all worked very well. (The optional initialization will take overnight to complete).
Now I have full redundancy and speed.
Each unit of 8TB is actually made up of two internal 4 TB hard drives.
With RAID 0 (aka "STRIPING") you have twice the speed but zero reliability.
Thats how the drives ship from manufacturer.
With RAID 1 (MIRRORING) you have redundancy but at half the capacity (8TB become 4TB, 4 become 2 etc).
So I put two of these on top of each other (a total of 16TB) into a RAID 1-0 configuration which basically mirrors (protects) a pair of striped drives, giving me the benefits of both at a cost of reduced capacity.
Peace of mind is what it does.
With hard drives is not a matter of IF they will fail but of WHEN they will fail.
So I ended up with 8TB of redundant space (two identical 8TB copies) mapped out over 16TB with striping thrown in for speed of read access.
No fancy controllers, no special enclosures, no goofy software.
Sits in the back of the monitors quietly basking in a soft blue light. I like the lights which are only detectable when the room is pitch black and the monitors are off. And I couldn't detect any noise or sounds from the drives. In fact one day when the drives were powered down (cord pulled from wall) the only way I noticed it wasn't on was when the drives were missing from Finder. So I truly can NOT tell any sound when they are operating it.
The whole thing (computer, drives and monitors) sit on top of glass-top desks. Each drive stacked on top of the other in back of the monitors.
But so far (several months) no headaches yet.
Hope to have none.
I still back up (Time-machine) to other drives on top of all this. I have a photography based business as well as tens of thousands of family files.
Sadly, the refurbished 8-TB drive is not like the brand new units—their internal components rattle. We contacted G-Tech again and they sent another drive. It arrived with the same problem except this time, only one of the Thunderbolt ports was usable.
We contacted them again and made a reasonable request that they confirm their outgoing drives' internal components don't rattle and that their Thunderbolt ports are functional. RMA was arranged for us to ship the drives back to them for analysis and we hope that they will fix the problem.
We do a lot of video research and each drive is critical to our operation so dealing with the failed hard drive and with the replacement drives that arrived in unacceptable condition has really tarnished G-Technology's position in our book. We will definitely look to other external hard drive manufacturers for future purchases based on the poor system they have in place for handling drives covered under warranty.
April 25, 2014 revision:
Well my first review of the G-RAID was fairly positive, but my experience with the drive has taken a turn. It started when I would get a disk error message when Time Machine kicked in. Going to the OS X Disk Utility showed that one of the drives in the G-RAID was bad. The unit was only about four months old and still under warrantee. I called up G-Technology and while they seemed surprised by the failure--the help desk person seemed to indicate that failures with these things were rare--they immediately issued me an RMA number. I sent the bad unit back to them and they immediately sent me a new `refurbished' unit (more on this later). In the meantime, I had gotten myself another 8TB G-RAID. When I got my replacement G-RAID I set them both up in an alternating dual Time Machine array. Later versions of OS X allow you to do this.
There are some troubling aspects to this entire episode. First I was using my G-RAID as my sole Time Machine backup. When it failed, and before I was set up with a replacement, I had to count on the reliability of my iMac's hard drive--statistically speaking a relatively safe proposition. However, what if I had been using the G-RAID as the sole depository for some mission critical data? I would have had a tough problem on my hands. At least now I am using the laws of the physics of failure to my advantage, but it is still something to think about. Now about that refurbished unit. It is fully factory refurbished and guaranteed. Cosmetically there is no indication that it is not a fresh unit. It also means that another G-RAID either failed or was returned for some other reason.
