There was a problem filtering reviews right now. Please try again later.
The only down side of this drive is that it's case design, it's not very good if you want to hang it on your keyring. The placement of the lanyard hole is a bit odd, and the slide catch sticks out a bit.
I got constant error messages using this app the device got for really hot using this app most of the transfers failed using the app. Subsequently after DELETING THE APP I've been able to go into settings on my phone and utilise the USB option within the settings and copy data and files back and forth successfully without any problems errors or heating of this device so I have been able to use it with my phone and then transfer data to my PC. still with Android devices phones it possibly require some technical skill in order to be able to do this.
So far this product has been slightly better than useless. You're taking a large risk using this device with an Android phone if you think that is going to work as is claimed... And error messages from failed transfers prompting a request to send via email the log get.. The following message..."
There was a temporary problem delivering your message to email@example.com. Gmail will retry for 45 more hours. You'll be notified if the delivery fails permanently."
Performance is no better than a $5 drive of the same capacity I bought from China last year.
Waste of money and going to the bottom drawer, to be given to someone I dislike.
One star because I'm not permitted to select zero
I bought this to have a little more flexibility in transferring files between different devices. By far the best price I could find both online and in-store (Officeworks had it for nearly twice the price!)

Le test a été réalisé avec un PC ultra portable équipé d’un disque dur SSD M2, et la clé connectée sur un port USB-3.1 puis un port USB Type C
Un fichier de 10G a été enregistré puis lu par la clé.
Les résultats sont identiques, entre la connexion USB 3.1 ou USB Type C
En écriture: 15 mo/s
En lecture: 140 mo/s
A la lecture de ces chiffres, pas d’ambigüité... cette clé de très grande capacité n’est vraiment bonne...qu’en lecture.
Sa fonction est principalement la consultation de fichiers.
Si vous avez des petits fichiers à enregistrer, elle fera le boulot d’une manière transparente, par contre si l’enregistrement de gros fichiers est votre quotidien, passez votre chemin.
Achat à faire en ayant bien défini son besoin.
Si ce commentaire vous a aidé, n’hésitez pas à me le faire savoir en cliquant sur "UTILE", cela fait toujours plaisir...Merci
Gave me 75MBps while copying a 3GB file from Laptop to Pendrive on USB 3.0 port...!
My laptop also has USB Type-C port...i did the same test as above...speed was same on the Type-C port...75MBps...but the speed was more consistent than USB 3.0 port...from start to end speed never dropped below 75MBps...!
While on USB 3.0 port, speed dropped from 75 to 40-45MBps for 7-8 seconds, then again it goes up to 75MBps, this happened 5-6 times while copying a 3GB file...!
My phone also supports Type-C port...i didn't check the speed of file transfer...but it worked perfectly...no problems...!
So overall great product...!
However, this is where the positives (for me) stop. I'm a wedding photographer and halfway through the day I transfer all images taken to that point over to my MacBook Pro (USB-C only). From the Compact Flash cards (160mb/s rated read speeds) I use a USB C 3.1 adapter and I transfer about 70gb of photos in about 10-15 minutes using his method. This is actual times experienced.
I then transfer the copy fro my MacBook to this 256gb SanDisk 3.1 drive (rated 150mb/s read speeds) For those who don't know, 3.0 is the same as 3.1 (gen 1) in terms of speed. They simply renamed 3.0 to 3.1 for USB-C devices.
This last process should take 10-15 minutes also, but in reality takes over TWO HOURS to complete. Why? Why does this take so long compared with the 15 minutes it takes for me to transfer from the SanDisk CF Cards using the very same ports and technology?
For me, this device is absolutely not fit for purpose. If I wanted these speeds I'd opt for a USB 2.0 USB drive.
SanDisk, any comments?
- Test setup (March 2018):
Straight into a Thunderbolt 3, 2016 15" fully spec'd Apple MacBook Pro. Using this SanDisk 64GB drive in new/unused/pre-formatted (FAT32) condition, straight out the packaging.
Tested using Blackmagic Disk Speed Test, at Blackmagic's 1GB and 5GB sizes. Using the drive's USB-C plug or it's USB-A plug (with an Aukey USB-C-to-USB-A adapter) directly into the MBP:
50-60 (write) / 160-170 (read).
So read's on an empty drive are as expected, write's are a bit slow; but TBH they're well within what most of these flash drives' performances tend to be that advertise themselves at the "150MB/s" rated standard.
If you want to spend 2-4 times more on a flash drive that advertises newer "300MB/s" speeds, then of course you may get around a doubling of the read and writes shown here. But of course you're paying usually significantly more for the privilege, and those flash drives are typically much bulkier as well, this one is only 4x2x1cm in size. Also, there are currently NO others (or at least none from main brands) on the market that do both USB-A and USB-C on one stick.
This does the expected speeds, connected using the expected types.
As of March 2018... If you need both A+C connection types, this is the one you're gonna need to buy. If you want faster speeds, at a higher price (19 quid for 64GB model), whilst sacrificing having both A+C USB connections, then look elsewhere.
EDIT (one week later):
Two quick points...
1) Faster drive.
Those looking for SanDisk's ~300MB/s speed drive, which is more expensive (~double the price/GB), bulkier, only has a USB-A port and no USB-C port. Then the "SanDisk Extreme PRO" the current one they do in 128GB & 256GB sizes:
I should have said originally, Mac users will likely want to reformat the drive in Disk Utility app.
The drive natively comes in FAT32, which only allows max file sizes of ~4GB. So I used "Mac OS Extended (Journaled)" and "GUID Partition Map" type. Likely only work on Macs though, but that's my work environment. Speeds quoted in main review above remain the same, BTW.
ExFAT could also be used (not sure whether that's as "Master Boot Record" or "GUID Partition Map" type? – I think the latter is best for newer OS's like Sierra onwards or Win 7 onwards?), but that's got limitations (e.g. max 11 character drive partition names), see here:
Hope this helps any Mac (and Win) users who are unsure.
Now the good parts, easy to use and fits in phone and laptop easy and works without any 3rd party software in phone( oneplus 6t in my case). Speed of data transfer is fast in fact this is the only pendrive that actually gave me 155MBps rate at its peak......before succumbing to inevitable ( overheat). That is good speed in my eyes. Lastly built, well its decent has some wobbles here and there nothing much, long term use still needs testing will edit the review if issues arrive buy yeah so far so good. Photo added of its fall start and prior to it.
Test rig asus rog strix laptop and OnePlus 6t phone. Took less than a minute to heat in room with mid 33ish degree temp.
