SanDisk Professional 4TB G-Drive SSD - Ultra-Rugged, IP67 Dust/Water Resistant, Portable External NVMe Solid State Drive, Up to 1,050 MB/s, USB 3.2 Gen 2 - SDPS11A-004T-GBANB

I almost returned this drive because it would just hang and crash Mac's finder every time I plugged it in at first. Updating the operating system to the version mentioned above solved the problem. I formatted the drive as APFS in Disk Utility and it is running well. It's not the fastest possible USB-C connection for these new Macs (which theoretically accept connections that are twice as fast) but those faster-connection SSDs are only just starting to hit the market, so they are more expensive, less battle-tested, and choice is very limited–whereas these G-drives have a long history of use and are starting to come down to the right price point (still quite expensive though). The drive does not seem to overheat as long as you have it in a ventilated area. I edit 4k video with it and have done so in home office, cafes and planes. The portability and reliability are top-notch.

This is the most recent G-Tech drive acquisition, and it is used primarily for backing up key data on a Mac Studio computer used for CAD, photography, and music.The G-Tech drive is not as small as some, but it is very robust, especially thermally when transferring a lot of data at high speed. I have had other drives fail because at the speeds my key computers are capable of running, the drive had no thermal throttling and inadequate cooling. This has never happened to me with this G-Tech series.

I use this 4Tb to back up images on the Win 11 desktop and laptop. I have other 4tb SSD externals that are at least twice as slow as this drive. It is very fast and easy to carry anywhere. An excellent drive!

Works as advertised. Speedy. One thing to consider is that is not recognized by a Windows PC "out of the box "...needs to be formatted

I've found this doesn't always mount or start up like it should. I have two of the 2T units and they both do it. I'll have to plug and unplug before they finally work. And then sometimes they work like a charm. And then there are the times when I plug one in and it uploads everything so fast I can't believe it and then the next time I have to unplug and replug while it sits there and spins its wheels. Wish I could figure it out. They are the perfect size. They are amazing when they work but frustrating when they don't. Both my laptop and desktop are one year old Macs.

I use this drive to store video files I am not currently working on. It is fast, quiet, reliable, and it doesn't get too hot (warm, but not hot). Plug and play with my MacBook Pro, with transfer fast enough I can edit in premiere pro directly from the drive if necessary.5 stars overall.4 stars for value because, IMO, at $259 for 2TB is seems a little on the pricey side.

Data transfer rate (write speed) copying slowed down to less than 1/10 speed when 75% full. Amazon customer service said I did not need to turn the item to receive refund. A week later a 3rd representative told me that the other two were incorrect. So I went to return the item to a drop -off location (UPS store) and was informed that I had to pay for a box and that that is the new policy with many Amazon returns. Then I was informed by Amazon that it could take up to (3) weeks to receive refund. And this on an item that I paid express price to receive. I am now striving to diversify my spending. Amazon does not care about me and this external hard disk drive was a FAIL. Sticking with my current brand.

I use it to record sports . Easily to transport and convenient for reviewing film. The only thing that is difficult is when used for a Mac it doesn’t pick up with a PC. For me , that has been the only issue . If you don’t have to use both which we don’t now then it is great. Works fantastic Mac to Mac. We have two!
