Works well - I bought this flash drive and so far it works really well! I would definitely recommend it to anyone who needs extra storage for wedding photos and videos, honeymoon pictures, or even just their phone gallery. I would probably buy another one specifically for my phone photos. I also really like that the quality of the photos stays the same as the original when you transfer them over. The only thing I would mention is that the 512GB isn’t technically a full 512GB because about 12GB is already used by the files that come with the flash drive, so you actually get a 500GB of usable storage. It’s not a big deal for me, though, and overall I’m really happy with it!

Fast and reliable! - It really is quicker than a regular flash drive. Much more reliable. Sure, a little larger, but it works much better. Maybe I just needed the upgrade, but this works great for me. I'd buy it at 1TB if I could.
