SanDisk Professional 7.68TB G-Drive Pro Studio SSD

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.

I've been buying G-technology (now SanDisk Pro) drives for more than a decade. When friends ask about external drives for video playback, photo storage, serious back-up, these are the drives I point them to first. I've never had one fail (ymmv), all of the drives I've ever purchased are still in operation by myself or a family member. The only reason I even buy new drives is I keep filling them up. The speed and stability is extremely reliable. I've never found the drive noise to be a problem, but if you need to do audio recording you will encounter read/write clicks, so placement is important.The only reason I don't give these a higher portability rating is because they are not bus powered (I would not expect them to be). If you do want to move these around our travel with them you will have to deal with the cabling, and if you do need to transport drives lots you should be familiar with proper care to avoid damaging the drive mechanism (these days, I'd drop the money on fast SSDs for travel).If you need speed and reliability, these are always a safe bet.

This is okay as a backup drive, it's not very fast, about 240MB/s on Mac intel even over T3. You have to relocate the feet and rip off a warranty sticker to put a new drive in there, and the new drive ideally will have metal studs added to the sides to ride in the rubber cushions included. I only got 260MB/s on a bigger replacement drive. I didn't get much noise from this unit in general, noise may be coming from people's drives. I wasn't able to get my monitor working via the T3 daisy chain. The daisy chain requires the drive power to be on. Keep expectations low and you won't be disappointed.

I have recently purchased this particular external storage for my photography, I have other smaller externals from OWC, LaCie and SanDisk. But they are were more for my MacBook and this particular G-Drive I got to back up both my Photo's and my iMac. So now I'm reasonably safe with my Data. Of course I just found out that my video card is beginning to die, just perfect!

I have dozens of these drives for storing film footage. I used large LaCie drives for a while but had two of those freeze. (The Rugged ones seem more reliable). So far, over a period of years, these SanDisk drives have been solid and reliable which is all that I ask.

I purchased this drive in 2022 for +$400. I only used 20% of the total storage. The drive failed in 2024 - I can see that the drive exists in Finder, but can't open it or see any of the files. No warning, just stopped working. Thankfully I had the data backed up via a cloud service that covers external drives. Complete waste of money. Buyer beware.

I talked to a friend and he mentioned you should be buying a SanDisk and what we found out is G Dr. is a SanDisk. It’s a good drive they work very well they’re quick fast and they just do the job I have a lot of these hard drives from my music workstation and they’re all mostly thunderbolt two interface drives and one of them has a USB but it’s just a good good drive I’m not gonna get anything else because I really like these drives and that’s it!
