Great Build Quality - Windows Users: Read the Instructions!
I recently purchased the SanDisk Professional 2TB drive, and I’m very impressed with the quality. I am using it for video editing and portability, mainly. Often, product photos can be misleading, but this device looks and feels exactly as pictured. If you are using a PC and the drive doesn't seem to connect or show up immediately, don't panic! The drive is likely pre-formatted for Mac. To get it working on Windows, you simply need to reformat it. Check the instructions! Look for the "Help" section in the manual that came in the box. There is a QR code provided that takes you directly to a guide on how to reformat the drive for Windows compatibility. Once reformatted, it works flawlessly and is incredibly fast. Overall, it's a solid, professional-grade device. Just make sure to follow that QR code, if you're on a Windows system!

Works but Slowly
Well made and good value for price. However it is still an old fashioned spinning disc drive and therefore quite slow compared to more modern drives.

Your computer will not see it. Good luck on tech support.
Its not my job to be an uber tech. in this day and age. a flash hard drive should be BASIC to have plug and play. Even all the support is about "not be able to see the device" which exactly my issue. I have brand new machine on windows 11. It doesn't show up no mater what. I tried everything they said, short of reinstalling the drivers, not going to mess up my computer to make their crap function. I have NEVER had this issue ever with an external hard drive. I have been working on computers for 25 years. I can build PC's and work in advanced web development and design. I'm not a beginner user and this thing is garbage. The disk manager can't even see the unallocated space. Even in reboot it doesn't see it in the BIOS. I have plugged into 4 USB ports and restarted my system as suggested several times. All that left is the reinstall the drivers. NOT DOING IT.. F U guys. Your drive should just work. Its a giant flash drive. This a joke. Nothing works anymore. The bigger the brand the bigger the issues. Rushed manufacturing, poor wages, race to the button line, AI doing QC on code. Whatever the reason?? profit over quality everyday. STRAIGHT TRASH. I will never by a Sandisk ever again.

Solid product, works with no fuss
Very happy with it. I tried what billed itself as a network attached drive, and found in the documentation that it wouldn't work a network. So I returned that and got this SanDisk for a USB solution. Worked straight out of the box and got my Mac Time Machine running with no fuss.

Reliable spinning disc hard drives
These are the most reliable spinning disc external hard drives that I’ve found. If I have one, I have at least 15 in a variety of sizes. They’re workhorses!

SanDisk Professional 1TB G-Drive ArmorATD
this wasn't exactly what I wanted originally, but it has worked fine as an external hard drive for backing up my laptop computer - hopefully it will continue to work fine for many years as I have had others that quit working after a short time in operation

Love these drives
I love these drives! I use them to keep personal and business items separate and to keep my computer running smoothly as the hard drive isn’t having to store all my files! The drive is durable, light, and easy to pack to travel with.

Best for film courses
Quick and easy to understand how to place files as well as with ejecting the hard drive. Using this as a film minor student for completed film projects.

Purchased this November of this year. Plugged it into my PC via the USB-C connector and nothing. It gave a white light for power then turned to 3 quick flashes, solid white, then repeated. Got a dud on delivery. Very disappointed in such an item.
