Great portable USB drive. I like the fact that you can switch from USB-A to USB-C.

Took all my stuff from phone & still has half the space still available.. also has neat app to help mamage info/files etc

I am very happy with this purchase. I got this on sale for less than 10 bucks and it’s been extremely useful.

There are 2 sides of connector, works with my PC and Smart phone. The access speed is excellent

I love that I can plug this into my phone and my computer.

Its extemely convenient to have both a regular USB as well a USB C but the transfer speeds leave much to be desired at only 100mb/s. Cant complain much with the price point.

Perfect for my daily use, i work in a hospital and it makes my work easier

Great little flash drive conveniently switches between Type C to USB 3.1 and attaches to a keychain. Great for Network use or IT

Very light weight flash drive, but fast. I have been using it for a couple of weeks now. I really like it.

This was so easy to back up pictures on cell phone.

Up today it is very practical for its size and capacity !!!

Love the reversible nature of this minuscule acre of portable storage. Only issue I have is that it’s small and flexes so it would be easy to lose or break.

It does what it promises but the very thin plastic enclosure does not inspire confidence. I would not trust attaching this to my keychain. The actual drive could easily pop off leaving you with a useless cheap peace of plastic attached to your keys. The plastic isn’t very sturdy either and likely to break but the drive would probably fall of before that happens.

I work as a DJ, and I already had two of these USBs. I bought them 1.5 years ago and they still work great. Rekordbox exports happen at high-speed — in just a few minutes for large syncs, and just a few seconds for small syncs. But I bought a third one of these last month, and unfortunately it's so slow as to be non-functional. I started a Rekordbox export right before I left the house, and when I came back the sync was only 12% complete — 20 hours later! I re-formatted the drive today and tried exporting again, but it's still so slow as to be unusable. I'm seeing that other customers are having this same problem. These drives have been great in the past but something is seriously wrong with the new ones. Frankly I'd like a refund.

the dual drive design is really convenient. and the transfer speed is ok

San disk always makes a great product! Needed this thumb drive for business and it’s been doing great!

Is this a scam...? I can barely write files to it... this drive performs just like the earliest USB 1.1 drives from 25 years ago, and I've never experienced a USB drive with such bad performance for a VERY long time. 1) The port it is attached to works perfectly fine with other devices. 2) I'm copying files from a gen 4 nvme drive that reads beyond 7,000 MB/sec, and it can only write to this USB drive in a few megabytes, or even just in KILOBYTES per second?!?! Did we time travel back to 1999? I'm obviously not expecting it to write at the speeds the nvme drive can read at.... I'm not even expecting it to be all the fast, just like other USB drives, but Kilobytes per second...? Really...? (see attached screenshot -- and that "spike" of performance before it fell off a cliff, which if often does, is only like 8 MB/sec) 3) I have other SanDisk USB drives that perform just fine on these same USB ports. 4) I have other non-SanDisk USB drives that perform just fine on these same USB ports. 5) This drive performs just as horrible with both the USB-C and USB-A connectors - even trying multiple different ports of each type. 6) I tried re-formatting the entire drive to both exfat and ntfs - both are the same and both are horribly slow. 7) Even just creating an empty folder is ridiculously slow, it takes 3 seconds just to set the name of a folder. How is it this bad?! 8) Deleting files is also insanely slow, only able to delete a few files per second 9) These problems persist on another completely different computer, which also works fine with all other USB drives. These dual drives are barely functional as described above. 10) I'm also not just writing a lot of very tiny files, which I know can be slow with these tiny USB drives. I'm also not writing just 1 really huge file either. I need a drive that will handle a mixed usage. The performance of this drive is so far below my already low expectations of USB drives. I know these are not nvme or even sata level performance -- not even close. I'm not expecting that at all. I've used a ton of different USB drives, and still I regretted buying these within minutes of opening them. What happened here SanDisk and BestBuy? This product is so far below the expectations I have for a basic USB drive. The product model number "SDDDC3-128G-A46" doesn't even exist on the SanDisk (or Western Digital, the company that owns SanDisk) website. They have a similar one, but it ends in "G46". That is quite concerning, maybe it is a dud product that they are ashamed of? I recommend saving yourself the time and energy and avoiding this product.

the best store to buy technology. the staff very friendly and attentive. and with very good offers.

Works as intended. I can easily transfer files between various computer and my phone.

Great works fine good to have and save your pictures from your cell phones to save memory
