JOIOT 64GB USB C Flash Drive Dual USB 3.0 Flash Drive Type C + USB A Portable Type-C Flash Drive 2-in-1 USB-C Thumb Drive for Smartphone Tablet Computer Mac iPhone Black

I'm not super picky about transfer speed. It seemed fine to me. I used it to try to transfer embroidery files. It went through but unfortunately the sewing machine couldn't read it. But besides that, I'm very pleased. I've used it for photos instead. I like the concept of having two different connectors. I only need the USB part but I'm glad I have options.

This JOIOT 128GB USB C Flash Drive 128G USB 3.0 Type C Flash Drive OTG Flash Drive 128G Dual Flash Drive is a really nice device. it looks smart and it is smart. it move fast a the capacity is as advertised. i also love the c type port as i am tired of cables so i can transfer my files from my phone in no time. for the end: the price is more then fair for this product

I have tested over 20 of these JOIOT USB Flash Drives and have been amazed at the performance of the drives. Out of the 20 Tested, 2 were 256GB, 3 were 128GB and the remaining 15 were the 64GB models. All 3 sizes produced the same amazing fast read/write speeds, however, for the benchmark screenshots I used the 64GB since theoretically it would be the model with the slowest R/W Speeds. In real world tests, I was able to copy a 14GB file over onto the drives without min heat and the drives never slowed down due to heat and they stayed cool to the touch. The only thing I can see as a problem is that out of the 20 drives I tested, 1 128GB & 1 64GB stopped detecting for no apparent reason. I was able to get one of the failed drives to initialize and format, however, it would crash the computer upon trying to read or write from it. I dropped my 5 Star Rating to a 4 Star Rating due to this reliability issue. On another note, I have been using these drives for over a year now and have found them to be my go to USB Flash Drives in my Tech Arsinal due to their speed and flexibility with the dual USB-A & USC-C connectors on them. Its also a nice feature that the entire drive is made of aluminum and feels more sturdy when compared to typical USB Flash Drives. I discovered that they sliding connectors can break if they are forced inserted too hard, so that is a another concern. however, I will chock that off as me brute forcing a delicate piece of electronics. I was indeed impressed that these drives do use a better JMicron Controller that is often used in USB External SSD Enclosures. In closing, I can and do recommend The JOIOT USB Flash drives when you want a fast & sturdy USB Drive.

I have both a PC I use as a (Plex) media server, and a Mac laptop I use for loading music on my phone, surfing, and other little things. The PC only has USB-A ports, while the MacBook Air only has USB-C ports. I don't even need to find my adaptor when I use this, which is nice. It also had fast read/write speeds compared to my older flash drives, so I can highly recommend this device.

These newer versions are much slower when writing a file to it. The new version now takes 21 to 22 seconds to write a file that took less than 4 seconds to write to the previous version of this flash drive. It seems to be a 2.0 version rather than the 3.0 it claims. (I have tried a few of the newer ones and all are much slower than the ones I purchased several months ago.)

I was amazed of its speed. On type C its speed was 120MB/sec. While USB was 30MB/sec. The disadvantage is its size which make it easy to break especially by bending stress. 6.5 cm long

Works great. I transfer data between desktop, Android phone, and iPad. This device works perfectly for that. Only issue is the need for a short "extension cable" to connect to the "C" port on the phone and iPad due to the protective cases on each. Available here on Amazon for <$5.

I got it with the dual USB style connectors so I could either plug it into my Samsung Note 20 using the type-c or my computer with the traditional USB.... My phone won't recognize when it's plugged directly in. The drive gets really hot if left plugged in for at least 5 minutes. But aside from all of that, this pen drive is a good value. It provides easy access to additional storage to help clear off media from my phone.
