    Extremely fast drive with good reliability. I like the 4TB capacity on mine and its good to use if you need to free up space on your local disk. It is a little pricey when you go for higher storage levels, but it is well worth the price. I use it on my 14inch MacBook Pro and have had no issues.

    I needed at least 3TB in a hurry for a video project. This was perfect for my needs. I tested the write speed and it was over 4X as fast as my 2 TB external SanDisk drive.

    I use these mostly for video editing and on set data management. They have been very consistent on both Windoes and Mac computers. Just to note, i have not seen a viable reason to justify the pro version. These work just as well and are just as fast.

    NOT for heavy use (video editing)

    I want to love these drives. They're fast, tiny, silent, and the price is right. But after my first couple months with two of these 4TB's, I would never buy a Sandisk again. I bought them specifically as shuttle drives for video shoots, and have also used them as edit drives with Premiere Pro. Maybe the third time I transferred with them, I had a strange experience where one of them simply unmounted from my laptop (14" MacBook M1 Pro). Didn't think much of it, chalked it up as maybe I jiggled a cable or something. A few weeks later, I came back from lunch and my Premiere project had crashed. Again, didn't think much of it, happens all the time. This week however, the real nightmare happened. Premiere crashed right in the middle of some very time consuming work, and the drive suddenly lost write access. I had to cycle it a few times for it to even come back online. Now having done and excessive amount of research, I see the rumblings on Reddit and elsewhere that these issues are not at all uncommon with these drives, and there's even a lawsuit about people losing their data. There's no way I would trust it with even low priority material after a failure like mine, and to see it so widespread is incredibly disheartening. For context, I'm a full time film editor and do small video projects in my spare time. I immediately formatted both these drives in APFS for working on my Macs, and only ever used the included cables. There is no reason why they should be failing this soon aside from a defect. Now of course I'm passed the return period for Best Buy, so it'll be a good test of the supposed 5 year warranty to see what happens next. I've since moved my project to a Samsung T7 and have had no issues the last few days. Can't give that one a glowing review just yet since it's early days, but it's definitely just as fast and portable, and runs noticeably cooler. Steer clear of these Sandisks and look at other brands.

    This is an awesome small 4tb external hard drive, the only thing I noticed is that it gets very warm when using for long periods of time. My concern is overheating and potentially corrupting the data.

    This External drive is a lot smaller and less bulkier than the Non SSD versions that I use to save my documentation and worth the price I paid for it.

    Very unstable after 6 months of use. Almost lost all data. When I load data until it only has 1.9 GB of empty spaces, it becomes very hot. Then, the data is very unstable, and cannot be either transferred out or deleted.

      We're sorry to hear about the instability you've experienced with your drive. Performance issues can sometimes occur if the drive is nearly full, leaving limited space for stable transfers. We recommend backing up your data and running a full reformat of the drive to restore stability(https://support-en.sandisk.com/app/answers/detailweb/a_id/20821). If the issue continues, please get in touch with the support team for further assistance by opening a ticket at (https://support-en.sandisk.com/app/askweb) SanDiskConnections
