  • Best performance , reliability and price. Works with any device
Color: Black Size: 256GB Style: Up to 400 MB/s
Excellent Product for any device and was strategically purchased for Tesla car with dual port for iphone or android device to show to police officer right there on spot if tesla damages after incident and cant play video. Abosultely beast for Tesla cars and never dropped a single frame in the video due to lowest over heating buffer on USB stick is higher than output birthrate on all cameras writing at the same time. Highly recommend for iPhone, Android, ipad, android tablet or Tesla. Price is the best too for this class and nice data controller. Additionally, Amazon got 2 more stars to make it as 7 stars due that product arrived next day for 5-8 guaranteed for free. Love it a lot. It is smaller than on the image -smaller than half of the finger of the size. ... show more

  • Great buy
Color: Black Size: 128GB Style: Up to 400 MB/s
This was well worth my money. I have so much on my phone that I wanted to save. So, when I brought my new phone, I could start brand new without losing any of my old pics and videos or without instantly maxing out my new phones memory. And I still have enough space to do it again when I get my next phone. I love how small it is. I can go on my key ring without adding bulk or weight. ... show more

  • Works as expected.
Color: Black Size: 1TB Style: Up to 400 MB/s
Great USB drive was hoping that I could charge my phone with this at the same time of using it but to bad so sad. Small easy to loose, put it down and if I cover it and push what ever I covered it with and not pay attention I have a hard time finding it. My desk is messy. It does feel like it can take some hat of a beating so it is pretty durable. Write and read speed is good although I haven't measured it so it functions good. I mainly use it to watch movies I have. ... show more

  • Almost perfect
Color: Black Size: 512GB Style: Up to 400 MB/s
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! ... show more

  • Perfect for transferring stuff off your cell phone
Color: Navagio Bay Size: 128GB Style: Up to 400 MB/s
Works great, doesn't overheat, easy to use and transfer files or photos onto. The perfect capacity for my needs, which is to keep my Google account from filling up 😂. Will likely be purchasing a second one.

  • Faster than I expected Faster than I expected
Color: Black Size: 512GB Style: Up to 400 MB/s
I bought this SanDisk drive to finally free up some space on my phone and it's worked great! It was way faster than I had expected and the SanDisk Memory Zone app makes it a lot easier to take bulk actions like copying and deleting the original. I've used it formatted as FAT32 and it plays nicely with Android, iOS, and Windows. Having both USB ports is definitely nice for connectivity and the pivoting mechanism keeps the physical size of the drive nice and small. It has a plastic case and I haven't noticed any heat problems, even during big transfers. ... show more

  • Not what I expected Not what I expected
Color: Black Size: 256GB Style: Up to 400 MB/s
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. ... show more
