This usb drive is very small but transfers are reasonably quick for a flash drive and the capacity is large. There are both usba-c and usb-a connectors so it works with both my old and new computers. I am satisfied with the purchase.

I bought this item close to a year ago. Opened it and just let it sit since then. For some reason I have it in my mind that I couldn’t get this to work with the app due to the type of phone I have. Well, I just bought another flash drive that was faulty, and happened to stumble upon this in my purchase history. I decided to look into it further and realized that for an iPhone 15 you just need to transfer through the files app on your phone. I decided to try it last night, and was pleasantly surprised it worked. In fact I was able to download over 5100 picture and video files within 45-60 minutes lat night. I ended up working on transferring more today, and I have almost all 22,000 picture and video files transferred. With any other flash drive I’ve had in the past, it would’ve taken hours just to transfer a few hundred pictures at a time. To say I was impressed is an understatement. I did run into an issue that I’m not sure about, but all afternoon after selecting a thousand or so files it would alert me that I couldn’t continue with the transfer. I would attempt to make the transfer smaller each time and it would rarely work. On occasion it would eventually work when I only had a few pics selected. But the odd part is that a lot of those files actually did transfer once I plugged the drive into my computer. So I’m still not sure the reasoning on this. If anyone has an answer I’d love to know it! I’m notorious for never having space for taking photos on my phone, which has a 256 GB memory, so I’m super thrilled to finally get these transferred in a timely manner. Highly recommend. I will continue to buy more in multiple colors to help organize timeline.

It works, My phone storage was 96 percent. I transferred some videos from my phone to the flash drive and freed up storage space to 70 percent. Will be transferring more stuff to it. The size is very small but convenient to carry around. The set up was easy and transfer was quick. It is reliable and will definitely be of great benefit. Price was good. I also like the fact that I can use the C part on my phone and the A part on my desktop. Definitely great purchase

So far, I've been loving this drives speed and capacity. However, performance has been lacking as i noticed it disconnects rather frequently when used with my tablet and phone. Will updte when/if i find a fix but so far, Not deserving of a 5 star review. Update: Comparing this to other drives. It's slow. Annoyingly so. Writing to it literally takes about 2 minutes before even a small piece of the loading bar comes up. Even reading files takes a while. 🤦🏽♂️ Update 2: So I double checked the specs of my laptop just to make sure I'm not crazy. Confirmed the laptop has 2x USB Type C-3.2 Gen 1 ports and the drive is also USB Type C-3.2 Gen 1 and I have never seen this drive even get close to the advertised speeds. Extremely Disappointing! Update 3: I've found that the frequent disconnecting issue was a result of user error. Quick and to the point, Don't have your device in battery saver mode. I've had no issues with connectivity after finding this out. While the older 128gb sandisk pendrive i had didn't have the same issue this one has. I still prefer this as it doesnt get as hot as the older drive while having 4x the storage and slightly (albeit still slow) faster speeds. Worth it!

Been using it for a while now for videos and files and has held up, I like the dual design as well using both USB and Type C since somtimes you need to move from one port or the other depending on your setup haha, but really easy to use just plug in and it pops up, transfer speeds are good for small files and it's also a small fit for any setups that are close to a wall.

It’s that time of year again when the new iphone is introduced and like a lemming I placed my order withing seconds and now I just got one of the first batch, the new pro max model. While I admire the convenience of just saying yes a few times and having the new phone replicate everything in my old one, which is being traded in, this year is a little different. It has some major changes to the operating system and I decided to start fresh with the tedious task of reinstalling everything. That task can have its dangers though and I’ve spent all morning trying to do a backup to my Macbook and it didn’t go well. So backing up to an external drive seemed even safer, if it worked as I hoped. WHY SANDISK As soon as I started shopping my eyes started to glaze over, there were pages and pages of thumb drives and for some inexplicable reason most of them still had lightning connectors, which means I would have to use a chancy adapter. I don’t get it, we are at least a couple of generations removed from that now obsolete connector and companies are still selling drives at full price. Then I saw this one from SanDisk and I thought my search was over. This is a brand I have trusted for years and the first thing that caught my attention was that it has the now standard USB-C connector as well as the universal USB-A connector. As my cloud backup is only 8GB I chose one of the smallest sizes I could get, based primarily on the fact that I could get it the same day so I can do my back and start using my new phone. DOES IT WORK This question has to be either yes or no, it either does the job or it doesn’t. So as soon as it arrived I plugged it in. There’s no need to get into techie specs with something like this, in today’s world there rarely is such a thing as slow. Another thing we expect in today’s world is for something to do the job it was purchased for. On one hand, if judged simply as a thumb drive this one is okay – slightly overpriced and slightly cheesy construction. On the other hand they heavily promote this as a simple plug-in backup device for smartphones. What they don’t make clear is they don’t mean all smartphones. This is clearly intended more for the Android crowd and that’s the biggest strike against it – if plugged in to a current iphone it does absolutely nothing (in terms of self-running a useful backup app). In the tiniest font possible on the back of the hanger card they tell you, after you’ve already bought the product and brought it home, that it may not be compatible will all devices and they give you a website. Unfortunately that link is broken. By now it is clear that this is not what I expected. So I searched their website, which is actually Western Digital’s website, and deeply buried in there (it took about 10 minutes to unearth it) behind a lot of conflicting information I finally learned that to use with an iphone I have to manually locate the Files folder and drag those to the SanDisk … but not all files are located there, it takes a separate task to locate and save photographs, that still leaves some files that I would like backed up. In their FAQ tools they seem to make it clear that this really isn’t a backup drive for an iPhone after all. It sounded too good to be true. YES NO MAYBE I’m splitting my opinion two ways on this. On one hand it is a decent generic flash drive from a company with a good reputation. On the other hand it is basically useless as a plug and play solution to easily backup my Apple phone. Additionally I would like to see a bit more rugged enclosure. The plastic reminds me of the cheap flash drives they give away for free at carnivals and trade shows and does not give me confidence that my data is protected against physical damage. The balance of all that results in a score of three for average, not bad for some uses and not so good for others.
