    Super short useless cable . Decent speeds around a steady 750MBs. Not quite as fast as the Samsung t7 shield my experience. The drive is tiny physical size the portability is high . The price was good while on sale other wise too expensive while comparing it to a Samsung t7 shield.

    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.

    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.

    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 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.

    Didnt take a long time to transfer and I assume it will last a long time before it runs out of storage for photography pictures, The amount of storage and efficiency was great.
