This is perfect for fast backups for large hard drives. I love how compact it is.

All my favorite tv shows fit on just one I’m talking every dragon ball and g.I. Joe ext… all of them

Very large storage and runs really well, surprised something that small has 4 terabytes.

Great price was right its compact. My son will love it when he returns from deployment.

Great little storage device. Easy to use, options for storage amounts to suit many needs.

I loved this product as this was direct compatible with tesla car ssd slot and the Samsung ssd would not work

Initially, I was really happy with my purchase - sizable storage capacity, fast, and small form factor, all-in-one. I was planning to partition it and use it for both storing files and backing up my MacBook Pro. However, as I've since learned, this product from SanDisk was very shoddily put together, with poor quality components, etc. Another reviewer, Duped, mentioned an Ars Technica article entitled, SanDisk’s silence deafens as high-profile users say Extreme SSDs still broken, from August 8, 2023. I highly recommend everyone to read that article, as well as another article from Ars Technica titled "SanDisk Extreme SSDs are “worthless,” multiple lawsuits against WD say." The second article lists the "few" drive models that Western Digital, themselves, admitted are faulty: SanDisk Extreme Portable 4TB (SDSSDE61-4T00) SanDisk Extreme Pro Portable 4TB (SDSSDE81-4T00) SanDisk Extreme Pro Portable 2TB (SDSSDE81-2T00) SanDisk Extreme Pro Portable 1TB (SDSSDE81-1T00) Western Digital My Passport 4TB (WDBAGF0040BGY). This item is the first one on the list (SanDisk Extreme Portable 4TB (SDSSDE61-4T00)). I wish I had known about these issues then since i would have returned it immediately.

This is hands down the absolute best external drive I have ever owned. It's flash fast and haven't had a single issue using it so far. Highly recommended.
