    Great little thumb drive, Does actually work with IPhone 15

    Great little thumb drive, Does actually work with IPhone 15
    I’ve had this thumb drive for close to a year now and find it very reliable and convenient for transferring files from my different devices to my laptop. I recently got an iPhone 15 PM and was curious if it would work on it since the new iPhones now have USB C ports rather than lightning ports. I got on here and checked the reviews to see if anyone else had tried it or asked the question of whether it’s compatible or not. To my disappointment all the questions that were answered about it it indicated it didn’t work and that iOS didn’t recognize it and the SanDisk app doesn’t recognize it. Wanting to double check and verify myself I went to the App Store and re-downloaded a couple of Sandisks apps that I had previously used and gave it a shot. To my dismay the reviews were right and the App Store software from the manufacturer does not recognize it. I still wasn’t satisfied with that outcome so I plugged it in again and opened the “Files” app which is the iOS native software that comes on it from the factory. I hit the back button a couple times and got to the “On My Phone” folder and was delighted to see that the IPhone recognizes the thumb drive natively with no extra software required to use it and you get an extra 256 GB of storage(depending on your model). It works like any drive would on your PC. You can create folders, save any type of document you want and even have the option to format the drive if you so choose. Just wanted to pass this along to anyone who was wondering and may not be totally familiar with the iPhone. The only negative thing that I have to say about this drive, is that it does get rather warm when plugged in and using it via the USB port. It’s not really anything that causes any problems, but I can’t imagine it’s good for the lifespan of the drive running that hot.

    4.0 out of 5 stars MOST CONVENIENT, BEST VALUE/GB, TRASH WRITE SPEEDS, WORTH
    Reviewed in the United States on December 12, 2019
    This is an excellent storage solution on the go, and as someone with enough USB Type C and Type A devices, the convenience is a godsend that can't be matched by cables. Moreover, the SanDisk Memory Zone app is simple and works well, which surprised me because in the past I've thought SanDisk utilities were little help and annoying to use. I liked it so much and it was simple enough to use that I got one for my dad to use with his Android phone and laptop. I paid $22 for 128 GB, which is a good storage deal in 2019 IF all the specs listed are met...

    HOWEVER this is where I'm sorely disappointed. The read speeds are near advertised and acceptable, but the write speeds are far slower at about less than a third of what's advertised. Moreover, the drive gets concerningly hot, particularly when it is being used in Type C mode. However, both read and write speeds are a touch faster in Type C mode as well and makes me call into question the buses used to interface with the memory, if the drive really is USB 3.1. When I plug it into my computer, the disk label reads 3.0, so I'm not sure whether they marketed the information or labeled it incorrectly. Moreover, there was a rumour that this drive is actually a micro SD card slotted into a dual adapter they've rigged up, which I could believe due to the sad write performance of the drive. Not in the mood to crack it open and break it to find out, but I definitely will once it fails.

    SanDisk has a reputation and it kinda makes me sad to see a product miss the advertised marks this badly. As someone in tech, I keep an eye on the specs and rely on them to be true to the device which is why it frustrates me so much when a legitimate company makes mistakes and flat out lies like this. It makes me not want to give them money.

    So why did I rate it 4 stars?
    Because I'll be damned if this isn't the best flash drive I've owned, lies and all. I've been waiting for this type of drive for a while and most reputed companies haven't put one of them out yet, probably because the technology isn't good enough to have consistent enough quality in speed, which apparently SanDisk isn't bothered with ;) The convenience and the huge amount of storage for $20 on a drive that will actually work on all of my devices at a decent pace is too much of an allure to pass up. As long as the file isn't too big and I use this as a casual, day to day drive as most people will, this will work well enough. Moreover, the app is so dead simple and convenient for even the tech illiterate to use. May still want to attach to a cable for those 4K videos though.

    Speeds in my pictures were collected using CrystalDiskMark. Faster speeds collected through USB-C Thunderbolt interface on same machine as the USB-A test, run on 3.1.
