When I first got this drive I ran a test, backing up approx. 6GB of 1080p AVCHD video to multiple locations: this drive, a 1TB USB 3.0 external hard drive, and a cheap ADATA 32GB USB 3.0 flash drive. The files were being copied from an NVMe M.2 SSD, so there was no bottlenecking from that, and I had the USB-A side plugged into a USB 3.1 compatible port on my motherboard (and later repeated, using the USB-C side on a laptop, also with an M.2 ssd inside, getting the same performance). This drive spiked to around 90MBps write for a few seconds, then fell to a painfully slow average of 20Mbps. In the same test, the ADATA USB 3.0 flash drive wrote at a consistent ~50MBps, and the USB 3.0 external hard drive wrote at ~90Mbps. For small files this won't make much of a difference, but for anything over 500MB, prepare to extend your wait times significantly.
For this drive to write over two times slower than a cheap USB 3.0 flash drive is insane. The only time you get USB 3.1 speeds is reading, which it excels at, but to be able to read something from it in the first place, you first have to write onto it at incredibly slow speeds. This makes it a very niche drive, good only for writing short bursts of files, where you wouldn't need USB 3.1 speeds to begin with. If this were a low capacity drive that would make sense, but given this can go up to 128GB it will appeal to people who want to copy large files at USB 3.1 speeds like myself, and end up being a major disappointment when it takes 5+ minutes to copy a couple gigs of video.
The only scenario in which this makes sense is copying files from a smartphone, but at that point, the phone comes with a USB-C cable to charge it, which would work just as well if not faster to copy files from. Cannot recommend this for any reasonable scenario.
So far not impressed..
Yet to see if USB 3.1 performs any better
Plugged it in and everything seems to work nice. About 115 MB of storage is available, and no pre-installed security software comes on the drive. The sliding mechanism works pretty good too. I have tried both USB C and USB A. I Did a quick read and write test, and speeds are not blazing fast, but decent. I got around 150 MB/S read, and about 50 MB/s write, good enough for me. One reviewer mentioned hot hot this thing gets. I can vouch for that, it did get quite warm on me,but not during the read write test, and not during type he 48 GB data transfer, it was kind of just sitting there plugged in and when I went to remove it, it was noticeably hot. As long as it keeps working I wont mind, One thing I wish they would add is some type of water resistance, as my wife likes to wash my drives regularly with the clothes. I think the tiny form factor will probably make this problem worse. Its a good buy considering there aren't many hybrid flash drives out there to choose from. I have included a couple pictures for size comparison.

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...!
- 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.
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?
- le connecteur mâle USB type A est médiocre, il ne se branche pas bien dans 80% de connecteurs USB que j'ai testé (MacBook Air, iMac et hub USB), je ne sais pas si c'est parce que connecteur ballotte ou parce que la barre bleue n'est pas bien placée, il faut triturer le connecteur USB, ce que personne ne veut faire puisque ça abime les ports USB.
- le loquet pour garder sorti le connecteur USB type A ne reste pas en place, donc tout s'enfonce quand on cherche à brancher.
Je suis surpris que SanDisk ait lancé un appareil à la mécanique aussi approximative. L'électronique est bonne, mais la mécanique est le point faible de cette clé USB.
This USB has very fast write performance for its price (Blackmagic benchmark for 4G files is about 30MB/s longterm and real-life performance is also very good). I had those very small "dual" USB drives from top brand and some of their write speeds are about 5MB/s on average. You can find faster sticks but the size will be larger and be more expensive.
This USB stick is good value. Apple store sell a custom made edition of this model but charges £75 for the same 64G capacity.
The major issue is that the package doesn't come with a lanyard for connecting the USB with keychain and I have to buy those separately. The position of the connection for lanyard is at the middle of the body which is very odd. But given the price/performance and the reputation of Sandisk, I can live with that.
Ho scelto questo prodotto in particolare perché fra le offerte del marketplace mi sembrava l’unico non progettato unicamente per telefono, ma qualcosa di più simile ad una vera e propria chiavetta anziché un OTG “cinese”.
SPEDIZIONE E PACKAGING:
La chiavetta si presenta dentro alla confezione di cartone della Sandisk, bella protetta e avvolta. Direi anche troppo! Sono impazzito ad aprirla.
Il contenuto è semplice: c’è la chiavetta e basta.
Ottimo, perché vari foglietti illustrativi o altre cose sarebbero superflue.
FUNZIONALITA’ E DETTAGLI:
Inizialmente sono rimasto davvero basito da quanto è piccola! Per accomunarla a qualcosa di uso comune è lunga quanto la parte intagliata di una classica chiave per aprire le porte. Più piccola delle chiavette medie di circa 1cm. Ottima cosa per la portabilità, ma occhio a non perderla!
Al centro presenta da un lato la levettina “slider” che permette di far uscire la 3.0 da un lato e la tipo-c dall’altro. Dall’altro lato c’è un foro passante per inserire un portachiavi o un filo per tenere la chiavetta.
Davvero ottimo il fatto che quando viene riposta entrambe le estremità non sporgono dalla struttura e restano protette all’interno. Bellissimo il design un po’ alluminio spazzolato e un po’ plastica con una filigrana a piccoli esagoni. Ti fa subito capire che non si tratta di una cinesata ma di una chiavetta seria.
Ho scelto la dimensione di 64GB, che si presenta con 61,49GB di spazio disponibile. All’interno un file PDF che spiega come collegarla a dispositivi Android e un file .apk per l’installazione del tool di riconoscimento della chiavetta. Io li ho tolti perché non erano di mio interesse, ma ottima l’attenzione della sandisk ai dettagli.
Quando inserita nella porta del macbook, che è bella vicina all’altra, non crea ingombro tale da impedire l’uso della porta accanto. Tuttavia HO RISCONTRATO UN PROBLEMINO: le nuove porte tipo-c del macbook sono molto “dure”. Ovvero occorre spingere molto forte per inserire a fondo la chiavetta fino a sentire un click, che assicura una ottima tenuta. Questa è una caratteristica del computer che però si sposa male con l’anatomia della chiavetta! Avendo lo slider al centro, quando si va a spingere per inserirla, l’estremità tipo-c tende a rientrare nella chiavetta. Occorre esercitare una buona forza sulla levetta slider che, essendo in plastica, non ispira chissà quanta resistenza pensando all’uso da qui ad un po’. Non mi si è rotta o piegata, soltanto sarebbe stato più utile inserire una sorta di dentino di blocco per assicurare la tenuta della testina una volta portata fuori dalla chiavetta.
Detto questo vi allego nelle foto il report per lo Storage. Ho effettuato uno stress di 5GB con l’ormai blasonato Blackmagic Disk Speed Test. Ho attaccato la chiavetta dall’estremità tipo-C direttamente alla porta laterale del macbook.
Si conferma quanto detto dalla SanDisk, la velocità di lettura arriva anche oltre i 150MB/s dichiarati. Buona anche quella di scrittura che si attesta intorno a 56.0 MB/s anche a seguito di test ripetuti e con stress di differenti dimensioni (1GB, 3GB, 5GB).
Connessa al PC si apre subito, senza dover attendere tempi millenari per l’installazione di non si sa quali driver, come spesso accade con prodotti della concorrenza.
RAPPORTO QUALITA’ PREZZO:
Al momento dell’acquisto (luglio 2018) ho pagato l’articolo da 64GB soli 29€99€. Il prezzo per quella da 32GB era di 24,99€. Questa sproporzione non me la spiego, ma per 5€ conviene assolutamente quella da 64GB. (Dipende poi anche dalle vostre necessità)
Penso che sia un prezzo davvero ottimo, per una chiavetta con tali prestazioni e che permette una ottima flessibilità ora che siamo nel periodo di cambio dalle classiche USB Port alle nuove type-c.
Ricomprerei il prodotto senza dubbio. Anzi, sto valutando di acquistarne un’altra per poterla lasciare in una tasca dello zaino o in ufficio, oltre a quella che tengo sempre nella borsina del computer.
È ESSENZIALE SE AVETE UN MacBook Pro.
Spero che la recensione sia stata utile. Se ci sono domande o curiosità di ogni genere sono sempre disponibilissimo all’indirizzo che trovate sul mio profilo utente! Grazie e buoni acquisti!
La construcción es buena, en plástico, con un poco de holgura porque tiene piezas móviles, y en aluminio, muy bueno para dar un acabado Premium. Esto de que tenga aluminio he leído comentarios diciendo que se calienta mucho… es cierto que se calienta, pero el metal ayuda a disipar el calor, evitando que se quede en el interior, como haría el plástico, y mejorando el funcionamiento del dispositivo.
La velocidad, muy buena, tanto de escritura como de lectura, adjunto captura de pantalla. Probado en macbook pro 13” 2015 en puertos usb 3.0 (no he probado el usb-c, pero debería de ir un poco mejor) usando disk speed test y sometiéndolo a un estrés de 4 Gb. Muy estable tanto en escritura, variando entre 78-82 mb/s y en lectura entre 146-154 mb/s. La copia de archivos se hace realmente rápida.
Como digo, el otro pen drive, siendo también 3.0, la tasa de escritura era de 20 mb/s, decayendo con el tiempo… por lo que, lo devuelvo, y adquiero otro como este, que me ha dado muy buenos resultados.
The tech world is moving towards USB C with many new devices offering USB C in the mix of ports, or in apples case, the only port. This little USB therefore comes in super handy as it allows you to plug in to any standard USB/USB C device and means you only need to cary one USB with you,
The USB itself is pretty well built, it has a simple design with a plastic/metal housing, a small slider that you use to push either the regular USB or the USB C out and a small hole to attach a lanyard onto.
A small, but welcomed feature is that when you retract the USB the slider sits in the centre and stays there, unlike another SanDisk dual USB drive I have used in the past where the slider won't lock into place and as a result the USB's are always sliding out and exposing themselves.
Due to the metal body the USB can become extremely hot when transferring allot of data, however from what I can tell this does not seem to effect the performance, you may just want to be careful of this when in use.
I can't remember what format the USB came in but I quickly re-formatted it to ExFAT so it would work well on both my Mac and PC, this is really easy to do on windows (Cant speak for Mac as I've never formatted a drive on my Mac, I assume it would be just as easy however) and once done means you can transfer the USB between Mac and PC without issue.
The new MacBook Pro's have very limited storage unless your willing to pay a fortune for an upgrade, therefore this is a great way to cut down on costs with a new Mac as you can get a lower storage model and then one of these to store the things you'll use less often. I personally keep backups of my projects on the USB as well as some of my Steam games, the USB is fast enough to be able to download games to it and play them directly off the USB so you can really save some space by storing your games on here.
Overall the USB is a must have for new MacBook owners and would do just fine if you intend to use it as a regular USB stick, a future proof investment as more things will begin to move to USB C over the years so this should last you a while!
Sadly I was deeply disappointed.
This device gets very hot in use, is very slow when copying anything, it corrupts data and sometimes loses data. Reformatting it has no effect on either it's speed or reliability.
Because I use it at work and it carries sensitive information, when it started going wrong, I had no choice other than to physically destroy the device rather than return it for a refund.
It has been a complete waste of time and money.
FWIW I used it on both a MacBook Pro running Mojave and PCs running Windows 10.
So, the product is good and easy to copy small files from one pc to another pc or even to a mac. But, don’t expect to copy large files like more than 5 GB, print many files from the pen drive or watch videos etc without it heating up.
I returned it for a replacement, and have had exactly the same problem with the second device.
I also tried the USB-A end in my Mac via a connector cable and it worked perfectly so the problem definitely lies with the USB-C end of the device.
Poor design and seemingly poorly made. Returned for refund and will be trying alternative brands.
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.
