SANDISK 64GB Ultra Dual Drive, USB-C & USB-A, Up to 150MB/s Read Speeds

I initially bought two of these USB-C/USB-A dual thumb drives to use as backups for my data. I like them because they are compact, reliable, fast, and very convenient. I like that it's easy to carry around in my purse since it's so small. Also, my laptop has a USB-C port and two USB-A ports, so I really like the flexibility that I can use this thumb drive in any of those. Everything was going along fine using these for my regular data backups until....I put one of these thumb drives in my pocket and forgot about it, and sent it through the clothes washer and also put it into the dryer and "dried" it. I heard the clacking around in the dryer and...there it was. And when I took it out of the dryer, it was HOT. At that point, I decided to immediately buy an identical replacement for that one, and not take a chance on continuing to use it. I didn't want to risk that the washed one would fail on me sooner or later, have shorter lifespan, or loose any data. After receiving the third one (the replacement) and doing my regular backup onto it, I then decided to try to the one that I inadvertently washed and dried and....it works perfectly with no loss of data. At least so far. So for now, I have THREE of these and am keeping the washed one as an additional backup thumb drive. I really like the convenience of these thumb drives, the dual USB-C/USB-A ends, the large amount of data that they hold, and the reliability. I don't recommend that you send them through the washer and dryer like I did, but if you do so, well, now you know that it will probably continue to work! I recommend this thumb drive and am very happy with it! I write honest reviews to help others make informed purchases because I read reviews myself and appreciate how helpful they can be. I hope that my review helped you!

I bought this a while ago but I'm going through my purchases and wanted to leave a review for this item. I'm assuming most people know more than I do about these drives. I wouldn't buy one that was a well known brand. SanDisk has great support and a great app for managing the storage. It was exactly what I needed and does exactly what I wanted. I wanted something I could use for my phone and this worked perfectly. I would purchase another one when needed.

I've been using this now for nearly 1 year. Very happy with it. Being able to swap between USB-C and USB-A is a game changer, especially with moving pictures from a phone to a computer (or vice-versa). No problem with formatting, and over the last year there have been zero data integrity issues. Transfer speed is fast enough for me. In my case, the large 256GB storage capacitty is more than sufficient for any type of transfer, or frankly general-storage usecase that I can come up with. The material is plastic, but its well constructed. Value: In today's environement with today's pricing of $54.25, I would not consider this a good value. (-1 star)

First off -- I bought the 256gb version of this in 2024 for $25. To see that the price has since more than doubled is so, so sad. HOWEVER. I'm an overworked grad student -- to say my life is contained in this drive is an understatement. I recently kept this usb in my jean pocket after work and unsuspectingly threw those jeans in the washer. When I realized what I had done, the wash cycle had already finished. I really thought years of data is gone. I plugged the drive in and, lo and behold, MY DATA REMAINED INTACT!!! pretty much uncorrupted. Structurally speaking, I like that neither ends of this dual-compatible drive is completely exposed during storage, thanks to the slider feature. The only downside, and my persistent complaint, is that the USB-C end likes to wiggle up and down as time goes by when protruded, resulting in the inability for the usb-c end to protrude and therefore temporarily unusable. To fix this I need to use a pen or something to stick inside and forcefully align the stuck end back before the slider functions bidirectionally again. It all seems like unnecessary contact with the data-transferring interface of this product and could lead to increased wear and tear down the line. For now, it's just an annoyance. As long as my data remains intact, and it did (through an ENTIRE wash cycle !!!! ), I'm more than happy with it.

I’ve owned this Sandisk for almost seven years now, and it has been working flawlessly. It comes with both USB-A and USB-C adapters built in, which is a great feature. I highly recommend this product.

Nice price, good quality

Boring and works as expected on Mac Studio. Not sure relative speed but fast enough to store and read documents and videos

The USB drive is small, has two sided male ports (USB A and USB C) which can slide out of the USB casing. Note: USB A is the general keyboard and mouse USB connector and USB C is apple's charging cable connector which now a days is common in most smartphones. The USB drive becomes hot when being used on USB C port for large transfers and is common. It can be plugged into mobile phones which has C type charging cable. The actual storage that you would get would be 114 GB. It would never be 128 GB as the rest is occupied by the drivers to run the USB drive. The drive supports exFAT (default) and NTFS file systems only. The actual transfer rate depends on a lot of factors like the type and generation of USB connector, the type of storage, processor, motherboard, etc. Transfer rates are good. I've tested it and shared the results below. The transfer rates may have gone down to 20 MBps in case of 50 MBps for HDD. The 600 MBps mark for HDD (3) went down to 80 MBps and remained constant. 1. USB A 2.0 (copying to and from SATA HDD) - maximum transfer rate up to 16 MBps 2. USB A 2.0 (Coping to and from NVME or SATA SSD) - maximum transfer rate up to 200 MBps 3. USB A 3.0 (Copying to and from SATA HDD) - maximum transfer rate up to 600 MBps 20 MBps 4. USB A 3.0 (Copying to and from NVME SSD) - maximum transfer rate up to 600 MBps and 50 MBps respectively 5. USB C 3.2 (Copying to and from SATA HDD) - maximum transfer rate up to 100 MBps and 50 MBbps respectively 6. USB C 3.2 (Copying to and from NVME SSD) - maximum transfer rate up to 130 MBps and 50 MBps respectively

主にテキストなどのデータやり取りで使ってます。 自分はMacなのでTYPE C 職場のPCはTYPE A 今までハブ使ったりしてましたが、これほんと便利です。 不満は一つもないです。

Gostei da compra. Produto original. Testado no funcionamento e na capacidade de armazenamento. Aprovado. Recomendo.

Clé 3.1 qui fait son job pour son prix. Transfert de fichiers rapide et constant. Les 2 types de connectique (usb et usb-c) sont bien pratiques (par exemple transfert de fichiers d'un ordinateur vers tablette avec usb-c). Rien à redire.

It was value for money and does what it is designed for, but when plugging in you have to push hard on slide button to make it lock in or it will not work.
