I've had my G-Raid 8TB drive for about two years now. It's been an incredible workhorse. I use it on my Macbook Pro via USB-C connection. No latency or issues editing HD videos. I am a professional TV editor (Dirty Jobs, American Chopper, etc.) and go through a TON of footage. This drive seems to hold up well. I use it with Premiere, Final Cut, and Avid. Worth every penny.

NOTE: I would not use this as a backup drive, though. It only has two bays, and in order to get the bandwidth, I had to stripe the drives RAID-0. So, if one of the drives fails, I lose everything. That's not a big deal because I use it as a media drive only. I keep all projects on a separate drive that is backed up remotely.

I already had a 6TB G-drive and want another 12 TB of storage. The drives are little noisy, but it isn't bad. Though I'm not a good judge of noise for I fall asleep to the TV on all the time. I love that you can daisy chain the drives, for it saves on using another port on my iMac. That's basically all there is to say about this drive, but in my opinion you'll love this drive just as long as you can stand a little noise and aren't a light sleeper if you have the computer in your bedroom.

I have used G-Tech drives for close to 15 years. They are built solid for a desktop use and I usually don't travel with them because of how heavy they are and so for that purpose I will use SSDs. This 28TB tends to be loud but that's because the fans are usually always running unless it's in standby mode. I'm okay with the fan noise because I know my files will be okay as this thing stays cool. I use this one mainly for media file backups while I edit with an additional G-tech alongside. They are both fast and suitable for heavy video files.

The tech support has always been very responsive, friendly and knowledgeable when I needed them or had questions. I had an issue where one of the removable drives wasn't responsive when I first purchased the unit and so I filed a case with tech support and they got back to me right away. Not only was it a pleasant conversation but they troubleshoot with me why it occurred and I was back in business in no time. Saved my butt and kept my client and that's why I will always purchase products from this company.

Be careful if you are a Windows user. Setup can be a little confusing and the directions on the G-Technology website are almost non-existent or you need a degree in engineering to understand them. My saving grace was my 15 years of old IT experience.
In order to get Thunderbolt to work I Had to update the BIOS, the drivers and the Thunderbolt control app. If you are going to use this with a Laptop you may need change to power setting on USB Root Hub Power Management in Device Manager. I had to change it so the laptop did not control the power to save energy. When it was left on I kept losing the connection to the G-Raid drive and it corrupted my Lightroom catalog.
I have setup the drive in Raid 1. I have done multiple speed test with Thunderbolt 40 Gps, Thunderbolt 20 Gps and the USB connection and the results with Raid 1 is that there is no difference in speed on 2 different computers. My results where about 260 MB/s Read and 245 MB/s Write, no matter what cable or connection I used. So I'm not sure why you would ever use the expensive 40 Gps Thunderbolt cables. As a side note, using an Active Thunderbolt 3 cable really didn't work for me, the laptop did not like it at all, I kept getting the blue screen of death with a driver error.

Rolled the dice on this HDD brick and opted to format as two, separate 14TB drive partitions rather than a mirrored RAID for secure redundancy. So far so good, decent transfer rates even with the amalgam of adaptors I needed to connect to an older MacBook Pro and G-Tech drives. As mentioned in previous reviews, this unit makes fair amount of noise and lights up pretty brightly, so keep that in mind if you're not powering down at night and/or sleeping within close proximity.
