This pen drive is very convenient to use as it can be plugged in to either USB-A or USB-C sockets on your computer. Speed for transferring files seems quite fast. Very happy with this product and would recommend it.
The JOIOT 64GB dual interface Flash drive is quite light due to the all plastic construction. I like the fact that the end caps are transparent so you can see which plug is which.
The drive performed well in the CrystalDiskMark speed tests depending upon how the data is transferred, the read speeds were just over 100MB/s regardless of the interface used and the write speeds were between 45 and 53MB/s, with the USB-C interface being the fastest.
I can’t comment on longevity but the price of around 30, at the time of this review, for a 5-pack of dual interface flash drives with good read speeds, isn’t bad.
This double ended memory stick is really handy for those occasions where you need to transfer data between USB-A and USB-C equipped devices.
So far they it’s worked absolutely fine for me, I believe it represents good value for money.
A good little USB drive for the money. Not the best made, but not the worst either and I am sure it will last well enough. Speeds were ok and the capacity was a shade under 30GB. Good enough to keep to hand as a backup.
The device seems to do the job it’s meant to do. You can easily connect it to both a PC and a phone/tablet using the USB-A and USB-C ports respectively.
When testing the speed of the device, it’s slightly faster than what a USB 2.0 device would be capable of, but not nearly what a USB 3.0 device can do. So it’s likely that the device is indeed USB 3.0, but that cheap flash memory was used inside, meaning it isn’t a very fast USB 3.0.
It’ll do the job, especially if you’re just using it to transfer things like photos, music, and videos from or to a phone and a PC.
This double-ended USB Flash Drive is well manufactured. The fit of both the USB connectors is precise – I have a number of regular USB flash drives made by top brands and found this drive competitive in every way. With the dust caps on it’s dimensions are approximately 64mm (2.52″) x 18mm (0.71″) x 9mm (0.35″). The body material is ABS, the dust caps are HDPE or similar. Note the caps are a tight-ish fit but easy to remove as shown in my video.
Making full use of both connections, I have been using this drive to transfer photo and video files from Android 10 & 12 Smartphones to a Windows 7 PC. Data transfer speed? It’s relative, given that the speed of the connected device makes a difference. From USB drive to my PC file transfer is about 37 MB per second. Never mind the numbers, it is faster than any of my other flash drives for similar tasks and I’m sure other people with better kit than mine would enjoy even faster rates. More important though, the files are always 100% perfect, no complaints from the PC about the drive needing a scan to test integrity.
There are of course a lot of uses for a drive of this type, it is compatible with just about any computer OS, Smartphone OS or bespoke device that has matching USB ports. The caps are a very welcome feature, preventing dust ingress and allowing you to safely carry the drive in your pocket. The type where the connectors slide into the body become too loose and difficult to use after a short while – this simple configuration is much better.
All-in-all, a very good flash drive.
Video: On a PC, left mouse click the maximise symbol, bottom right corner, to view the video full-screen. Tap ESC (Escape) key to leave full-screen mode. On a Smartphone, tap the video and pinch in-out to adjust the video size.
I don’t know if this is high speed or not but I’m not sure it’s that necessary for 32GB. Otherwise, this is convenient to easily move documents between devices that have different USB connections without having to use an adaptor or other equipment. The two caps fit on nicely and secure and the connectivity with my devices is as expected. I would use an external hard drive for moving or backing up large amounts of data but this is convenient for more every day use.
Quite a slow drive when I compare it to my other two SanDisk flash drives. With that said, it’s only going to be used as a third backup device for a variety of non-sensitive files, so not a problem for me.
Unlike with Scandisk drives, this one doesn’t have any encryption software included. If I was going to use it for sensitive data, then I’d most likely encrypt it with Windows BitLocker, which has been available from Windows Vista onwards.
Great to see the flash drive has both the old USB-A connector and the more modern and superior USB-C connector, especially as USB-A is gradually being phased out.
Having USB C and A connectors gives this USB memory stick flexibility, without worrying about the port of the device.
I copied a large file to it, and it sustained a copy speed of about 28MB/sec, it did go as high as 31.5MB/sec and would occasionally dip to 26MB/sec. Read speed was around 37MB/sec. The interface used (USB C or A) didn’t seem to make any difference to performance. All tests were connected to a USB 3.2 interface.
This isn’t the smallest USB memory stick, but it isn’t huge especially given it has two connectors on it. The connector covers are quite stiff, meaning they won’t fall off but they are also quite hard to pull off at times. There is also no retaining strap which means you need to be careful not to lose them. Overall a decent memory stick.
What a good idea — a double ended USB drive that can plug in to either a USB-A type or a USB-C type socket, without needing any adapter. When put into use, it did show up as 32GB. Good.
It is small and light, so easily carried around in a pocket of my laptop bag. I suppose I will soon lose the end caps. I hope I don’t lose the whole thing, as there is no way of attaching a loop or lanyard to it. I wish the 32GB capacity had been printed on the drive. I own a number of USB drives, and it is always good to know that you are using one with the right capacity. Oh well, out with the nail varnish.
Note that this 31.44GB capacity flash drive comes preformatted as FAT32, so if you work with files over 4GB in size you will need to reformat it as ExFAT. I am interested in performance with large files, and tested read and write speed using file sizes from 1GB to 5GB (the latter inevitably when reformatted as ExFAT). I found similar performance across file sizes, and overall saw read speeds of around 112MB/s with write speeds around 50MB/s. Using a USB 3.0 port of course.
The double-ended USB-A and USB-C connectors are very handy (the minor drawback being that you can’t fit the cap onto the back of the drive when using it).
