This fast external drive powers other SanDisk external SSDs to better performance on my iMac system.
This fast external drive has helped power (one at a time) other SanDisk external SSDs to better performance on my iMac system. Problems I had copying a large 3.8 TB photos library were resolved when that external SSD where the library was located was connected to the daisy-chain power supply from this G-Drive. I was able to overcome the previously dead-ended MacOS error Code -36 issues.This G-Drive's speed is also adequate to edit and render 60+ minute 4K videos on its external storage without dropping / hesitation. The 7.68 TB it permits has allowed me to rearrange and clean up files on other drives (2x4TB and 4x5TB) to make the most of the space they offer. Also, I've placed a cloud Sync drive onto it, which is permitting streaming upload of my large files - pics and videos, etc. (One has to rename the "Photos Library.photoslibrary" file to allow the contents to be copied up, as Sync does not allow the copy of library files).The result? This is like another level power boost to my iMac (2019) 1TB internal SSD, 3.6 GHz 8-Core Intel Core i9, Radeon Pro Vega 48-8GB + 32GB 2667 MHz DDR4 Ram system, now operating on MacOS Sonoma 14.4.Seems a bit costly, but I have been blessed to have the $ resource to be able to have made the jump to purchase it.The integrity of this drive vs data loss is another strong characteristic that affirms my delight in this purchase.

My purchase was for the G-Drive PRO, which is a mechanical hard drive, not an SSD.

There are some reviews for this drive on Amazon that say the speeds are terrible. Do not listen to them. They do not understand that this is NOT an SSD, it is an enterprise class SATA mechanical hard drive in a TB3 case. The bottleneck here is the mechanical hard drive. There are people complaining that this is not a "40gb capable drive". This is laughable pure ignorance of the technology and what they purchased. The mechanical hard drive inside is NOWHERE near capable of 40gb speeds. If you need huge mass storage the G-Drive PRO is an excellent drive. If you need the absolute fastest speeds then you should buy the SSD version. Just do your research to understand the technology you are buying.

The drive is excellent, but must be formatted for Windows. The online User Manual for this drive (G-Drive) at westerndigital.com contains detailed instructions to perform this step. The instructions refer to a Command Line prompt available by right-clicking the Start Menu, but I did not see this option for Windows 11. Instead, I use the [windows]+R key to bring up the command prompt. That allowed the necessary commands to be entered and the drive ultimately formatted correctly.

The storage is fine. It is the accessibility and speed that has issues. I find that I am having an issue with the use of the video files. Using a Mac Studio. When a video is open in the file the playback bar is missing until I switch and come back to it. This only happens sometimes. I also noticed it is a lot slower than using a SSD for storage. The upload/download times are noticeably different.

WARNING!: This drive is not pro. Not in 2020, 2021, or 2022.

It is advertised as a Thunderbolt 3 drive. However, it does not meet that standard's transfer speed (40Gb/s). Instead, it's actually a Thunderbolt 2 drive (20GB/s) transfer with a T3 cable. So half the transfer speed on a 12TB drive. Pro in 2020, 2021, 2022 is 40GB/s.

We made the unfortunate discovery on a shoot when it was too late to get any alternates. The transfers were going alarmingly slow, even for HD footage. Upon investigating, the "fine print" on the box revealed the issue.

I've spoken multiple times with GTech/Western Digital/Sandisk. They claim the drive functions "according to their" specification. However, it is not what anyone would expect from a drive advertised as Thunderbolt 3. Again, Thunderbolt 3 is 40Gb/s. So is "Pro".

Furthermore, the drive is having issues. It repeatedly puts itself to sleep though system preferences are set to never do so. Anyone who edits understands how slow and harmful that can be.

Capacity: 7.68TBStyle: PRO STUDIO SSDVerified Purchase
Bought 7.68 TB G-Drive Pro SSD - So far so go. Speed and reliability is what really matter when it comes to external drives. Though my 4 year old Mac comes with its own 4 TB SSD which is even way faster than today's fastest aftermarket SSD available. But I needed more space and this drive comes a bit closer to Mac's internal Apple's SSD, and am happy with it. But SSDs are still very expensive, prices need to come down.

I am mostly using it for my music library (DSD and AIFFs) and a couple of large photo libraries. However, 7 TB feels less than half of what I really need today.

The device was easy to plug in, and offered me right away (on my Mac) the 12 TB of Sorge I needed. I used it for a Carbon Copy Cloner target, and that worked great, and I had been using another 10 TB drive as a Time Machine drive backup medium, so now with twi G-drives (10TB + 12TB) I am fully backed-up and protected. This is a good company, with good products that I fully endorse!
