Review this product
There was a problem filtering reviews right now. Please try again later.
The read speed on this is as advertised and consistant 150megabytes/sec easy. Which is very nice.
When formatting with windows it reports 28.6GB of space, NOT 32...
Knowing the write speed of these I would not have purchased. If you are only copying files under 1gb at a time they will be fine.
The above example is copying from a SSD, i can move files to another SSD at 1000megabytes/sec so that is not the issue. USB sticks were set to use the performance profile in the hardware settings.
5 stars would buy one again.
The USB Drive is nice and compact. But while trying to create a bootable disk with it the speed was no where near 150 Mbps. It took lot more time than my old USB drive. It also gets hot while using..
It was also super fast to arrive. Super Small and stylish

La capacidad del pendrive una vez formateado es de 114GB.
La velocidad de lectura es estable, pero la de escritura oscila levemente.
Os adjunto imágenes moviendo archivos al pendrive para que veáis la velocidad, tanto hacia el pendrive como hacia el pc.
How can they dare to sell this as a 150MB/sec drive?
I copied a 2000MB file to it, after a minute it slowed to 13MB/second. I have old USB 2 drives that are faster than that!
I used the standard Crystal Disk Mark benchmark and there you go:
Sequential read 40MB/sec and write only 12.66 MB/sec!
I returned mine. I expected more honesty from Sandisk.
Una cosa preoccupante è l'elevata temperatura raggiunta dopo l'utilizzo, credo arrivi sui 50°C, che non mi fa ben sperare per la vita utile, soprattutto considerato che pensavo di utilizzarla come HDD OS per il mio NAS.
Per correttezza bisogna dire che il pcb è montato interamente sul lato in metallo quindi il surriscaldamento potrebbe essere semplicemente più facilmente avvertibile e anzi essere un segno di migliore dissipazione, staremo a vedere.
Passando alle prestazioni la lettura è molto buona (120-140MB costanti) la scrittura invece ha un effetto strano: scrive molto velocemente il primo GB (intorno ai 95MB/s) e poi crolla (a circa 20MB/s) senza più riprendersi. Ho provato con vari file di grandi dimensioni e manifesta sempre lo stesso comportamento. Sospettando che si trattasse di throttling termico, come accade per alcuni SSD, ho provato ad applicare due piccoli dissipatori in rame con pasta termica ma il problema persiste.
Considerato che in questa fascia si trovano delle vere schifezze con velocità da usb2.0 non mi sento di dare 3 stelle nonostante i difetti. La consiglio a chi cerca una buona chiavetta per un utilizzo normale, se invece puntate alle alte prestazioni sostenute rivolgetevi altrove a costo di spendere qualcosa in più (Samsung MUF per esempio). Io pensavo di sostituire la mia vecchia e ingombrante Datatraveler G3, ma le prestazioni non sono all'altezza (si vedano i test).
Seems to move files at around 30Mbps or so. Its slightly faster than some others that I have used.
However, this does get pretty hot. I think this might be magnified by the metal outer. I suppose it helps dissipate heat that is inherent in most USB 3.0 drives but because of the metal I went “ouch!!” When I first used it.
Hasn’t fried itself yet under heavy use so I guess its ok and an inherent design thing.
The flash drives are great.
I purchased 2 – one loaded with a portable operating system; Ubuntu Desktop and the second my Windows 10 installer.
The performance of Ubuntu running from the flash drive in a USB 3.0 port is great, even with USB 2.0 I can perform all the tasks I need perfectly fine.
Installing Windows 10 is a breeze, especially when built on an SSD drive the whole process is significantly faster.
Both are kept on my lanyard as they have decent size loop for attachment. They’re also a slim profile avoiding issues where there’s limited space on busy USB ports on desktops and hubs. The build quality is good, they come in different colours, they’re FAST, well priced and reliable.
I did have one concern though initially; the body is most part made from metal and when is heavy use they get extremely hot. That hot it’s difficult to handle and a bit of a shock if you forget the temperature and eject them from the machine by the metal surfaces. I have used the Ubuntu disk for extended sessions of 8 hours +; I’ve never noticed a decline in performance or any disfigurement of the drive itself. I have had drives that get hot before (not to this level) but they’re usually housed in a plastic shell. I can only assume that a. it’s a design flaw b. its an integral part of the design to disperse the heat generated.
I’ve been using these for a couple of months now, so it’s not something I worry about but just be aware that they get rather hot.
I’ve run some performance tests which you can view in the attached video, and they’re detailed below for both USB 3.0 & USB 2.0
- USB Deview, a small utility for managing USB devices with a feature to execute speed test for both read & write.
- Transferring a 546mb MP4 file from my SSD machine to the flash disk, then transferring the same file back to the desktop. I’ve recorded the time for these tasks to complete.

I recently upgraded my PC with a 4port 5Gbps PCI Express expansion card. This was easy to install, it doesn’t require additional power and has provided me with a solid set of 4 additional USB 3.0 ports. I tested it to see if it would power some of my more power hungry devices which was flawless. This is impressive considering the PCI card did not require and additional power from the PSU. These ports were used during testing too.

After closer inspection of the packaging, it appears that someone put a 128GB sticker over the original of 4GB (see photo).
I can confirm three main things that others have mentioned:
1. It gets extremely, dangerously hot during normal use, if even remotely taxed (e.g. transferring files bigger than a couple of GB or transferring a bunch of smaller files in one go, which takes a long time)
2. This excessive heat causes it to perform extremely poorly (it is fast when cool but chugs something rotten when it heats up)
3. Possibly as a result of the excessive heat, mine has now completely failed after only a few weeks of usage.
I'm extremely annoyed that I've lost some data that I can't get back. (The transient nature of USB flash storage means that I hadn't yet backed the stuff up, because it was work in progress and I was on the move so didn't have a way to back up until I got home, by which point it was a goner). It's getting replaced, which is good, but apparently that requires me to send in the old product with my data on it which frankly isn't ideal (luckily I don't have anything overly personal or questionable on it but that's not really the point).
They are smaller than I'd expected – about the size of an all-metal drive, but lighter and not as robust. I wouldn't expect one to survive for long on my keychain. The attachment loop curves up a bit, which is handy in showing which way up to plug them. With symmetrical USB drives, sod's law says I always try to insert them upside down.
They do get warm when they're being stress tested. I wonder if this is why Amazon buyers report a comparatively high number of USB drives – of all brands – that fail after a few weeks or months.
parte a circa 50 mb/s , ma subito rallenta fino a ad arrivare ad una velocità imbarazzante di 12,5 mb/s, quindi assolutamente inadatta al trasferimento di grandi file.
grossa delusione considerando che si tratta di un prodotto di marca.
unica nota positiva il rivestimento in metallo, almeno questa il cane non potrà masticarsela.
1. It starts writing at a pretty good speed and then suddenly drops the speed to somewhere around 5MB/s and eventually, if the file is large, it completely stops the process and fails. So, you can use it only if you want to transfer several small/medium sized files. Large files are a no-no.
2. Today, it completely stopped working and now it is not recognized by my computer. Also, neither can the TV recognize it anymore!
So, not sure of what I am supposed to do with this failed product.
Lo he probado con un archivo de ~10Gb, formateando el pen como NTFS, y al empezar la copia mantiene la tasa de transferencia esperada, pero al de unos 30 segundos empieza a caer hasta estabilizarse en ~10 Mb/s, con lo que la copia se eterniza.
