Note:
1. 1GB = 1,000,000,000 bytes. Actual user space may be less.
2. Speed varies depending on the host device, interface, use condition, and other factors.
3. Android device requires On-The-Go (OTG) support.
It arrived next day and I used it to transfer pictures from my phone to my PC thus freeing up space on my phone whilst being able to keep my memorable photos.
It trook only seconds to make the transfer to from phone to device and a few seconds more to transfer to my PC.
Excellent value for money and a real time saver!
This memory stick has a concealed USB-A plug at one end and a concealed USB-C plug at the other. You can slide out just the connector you need but I found it a bit awkward because the connector you were not using tried to slide out as you plugged it into a device. It is however nice to have both connectors available so you can easily switch between devices whatever type of USB port they have. The plastic case does not have a particularly premium feel to it and it is missing a point to attach a lanyard or similar.
I tested the memory stick with Drive Capacity Tester which confirmed a useable capacity of 125.82GB as expected from a 128GB stick. I also tested it with Blackmagic Design’s Disk Speed Test where the best speeds I got for the drive were just over 60MB/s write and about 120MB/s read.
My only complaint is with the price. At the current price of 10.52 it is about the same as a USB 3.2 128GB from a premium memory manufacturer that also has USB-A and USB-C plugs. Longevity is still unknown with this device. At this price, I can see no reason to buy from an unknown brand over a premium brand.
Not a speed demon but a neat drive
This drive is quite funky – double-ended for USB C and USB A connectivity, and the plugs get hidden inside. The ends are still open to the elements so there’s a chance of pocket fluff getting in there though, so be prepared. I’m not willing to try and plug it into both my PC and my phone at the same time, because that’s the sort of thing will kill all devices involved.
128GB, when formatted, will never be an operating system-usable 128GB. Some people don’t know this, and rant and complain that there’s gigabytes missing, when it’s just not understanding how file systems work. The drive comes formatted as exFAT which shows as 117GB – it’s still a 128GB drive. I’ve not been able to test that it’s a ‘real’ 117GB (having seen fake flash drives a few times in the past, which claim to be multitudes larger than the actual capacity) but I have confidence that it’s legit.
In terms of speed, it’s faster at reading than expected, and slower at writing than expected. Reading is generally 60-150MB/s and writing 10-25MB/s on USB 3.0; the listing suggests 70MB/s reading and 20MB/s writing. Testing with several different pieces of software on Windows 11, I’m getting an average read speed of around 120MB/s (nice!) and a write speed around 12MB/s (less nice!). 12MB/s is still within the normal range, but the results are rather lopsided.
But! 13, with a 10% off voucher at the moment, makes this 11.70, which is a brilliant conclusion because it means each usable gigabyte costs 10p.
After receiving this USB stick, as advertised one side is USB-A and the other is USB-C. I put this into my iPad and it was able to read it as well as my Mac and both showed a storage capacity of 125.42GB.
The way you expose the connectors either end of the stick is by sliding back the plastic cover. The cover can click into place either extended or retracted. This does make it tricky to dock the USB stick as when you push it into the connector the opposite cover slides back. It is easier to push from the back on the tip of the USB connector.
Once connected I did a speed test and was very disappointed to see average write speeds of only 7MB/s. Read speeds were pretty consistent across all tests of 101 MB/s. After writing to the disk a few times the speed started to increase slightly. I did a secure format which wrote wrote random data to the drive. I did this so all sectors had been written to. After performing the speed test again the write speeds did improve to an average of 20MB/s. Slow but much better than at the start. The max write speed seems to be around 32MB/s then this will slow to a crawl or stop for a few seconds then slowly ramp up again before repeating the process. All these tests were done via USB-C port. I did test via USB-A at the start and it was slower at and average of 1.9 MB/s
Overall I think this is a good USB stick with both A and C port making it versatile. It has slow write speeds but it is still usable. The price for a memory stick of this capacity is a bit on the steep side. You can get the same for around half the price albeit with on A or C connector in it. If you want both then go for this, if you don’t save the money and go for a cheaper one with 1 connector.
