SanDisk Professional 24TB G-RAID Shuttle 4 - Enterprise-Class 4-Bay External Hard Drive, Thunderbolt 3 and USB-C, Transportable, Hardware RAID - SDPH34H-024T-NBAAB

I never was able to connect the device with my Mac, and technical support was unable to provide guidance after 10 days. So I had to return it and will buy a product from a different company. Not worth the hassle.

Update: After ordering two more of these from Western Digital and having the same problem, I finally got to speak with a tech support person who knew what he was talking about. It turns out that drive has to be connected to the computer for it to power up (never seen that before); and I had a bad cable. So I'm changing my rating to 4 stars. I would have given it five stars except for these issues:1: Nothing in the quick start guide or the manual states that the drive won't power up if it's not connected to the computer.2. The previous tech support persons I spoke with never mentioned that either, and just told me to return the drives to Amazon.3. If I had known that the drive had to be connected to the computer, I could have figured out on my own that my cable was bad.Original review: I've bought four of these Shuttle 4 drives from Amazon, and ALL of them have been DOA! I plug them in, press the power button, and NOTHING HAPPENS! No LED, no fan movement, no sounds, nothing! The first two I bought were 48TB drives. SanDisk tech support said send them back to Amazon so I did. Then I ordered two more, this time the 72TB size. Same exact problem - DOA! And same useless advice from tech support. They just keep telling me to send them back to Amazon.

I like the concept of the Shuttle but the fan was on even when I wasn’t retrieving or importing files. Made no sense to have the fan running, it drove me crazy.
