The G-Technology G-DRIVE Thunderbolt 3 External Hard Drive (4TB) is an ultra-fast, high-performance storage solution featuring Thunderbolt 3 and USB 3.1 Gen 1 interfaces in an all-aluminum enclosure. The G-DRIVE desktop storage is perfect for storage-intensive applications like audio/video...
G-Technology G-Drive is using the latest technology for file storage/transfers - Thunderbolt 3. The build is extremely solid and the brushed aluminum case matches my iMac perfectly. But because of cost constraints, be aware that this is not a SSD but a 7200RPM build and simply doesn't offer the blazing speed that Thunderbolt 3 is capable of at this point in time. You are paying primarily for the storage space these units are providing. Here is the speed transfer breakdown by storage size of this new HD: 4TB: up to 180MB/s; 6TB: up to 226MB/s; 8TB: up to 205MB/s; 10TB: up to 245MB/s; 12TB: up to 250MB/s 8.27” x 5.12” x 1.79” I have not used an active TB 3 cable with this machine so I'm not sure if that would begin maximize the potential speed of this TB 3 External HD but it is constrained already with the 7200RPM drive. And so far, I really don't see any real-world noticeable gains in transfer speed from my FireWire 800 OWC Guardian Maximus HD to the G-Tech TB 3 HD. The ease of use on a Mac is the best - plug it in, my iMac recognizes it immediately and I was off and running with Time Machine and file storage/transfers. Finally, don't bother logging on and/or calling G-Technology (which is a Western Digital Company) to register your HD. The company is no longer accepting registrations on these products via their online support page or phone. I know - I just talked to a customer support rep last week and that is exactly what he told me. He told me to keep the receipt for proof of purchase.
These G drive externals are quiet and unobtrusive and are $50 cheaper than the very same G Drive that Apple sells.
It does what it does. But I should have bought G-RAID for a little more $ rather than this G-DRIVE.
