3.0 out of 5 stars Serves its purpose. 256GB model
By T. A. Nicolai on January 23, 2018
Capacity is great. Small profile is great. That claimed 130MB is read speed. Please note... write speeds state UP TO 15X over USB 2 speeds. Key words here are UP TO.

I use this device to store flac music files for playback in my car. I have plugged this drive into USB 2, 3 & 3.1 ports for writing purposes. I have seen extremely marginal performance differences between USB 3 & 3.1 (fluctuates between 35 - 55 MB when writing anywhere from 200MB - 2GB at a time). On a USB 2 port I get speeds around 20 MB on average. I will post test results and adjust figures as needed later as I am going from memory at this point.

On another point, the frame of this no longer appears to be made of metal. I would say it is made of some type of composite material. I believe this was done with a purpose on the manufacturer to alleviate the heat issues with the previous model (which I also own) While it still gets warm while writing, it no longer gets hot to the touch like the previous model did. The heat dissipates much quicker. Given that, I do worry about the longevity and duability of this device should it have to be used and plugged in frequently in many devices.

Overall, it serves my purposes. Write speeds could be better and durability could be an issue. Hence, my reason for three stars.

**********Edit**********

I have included Crystalmark tests (1 @ 500MB in size for USB 2 & 3). I did 5 tests while having it plugged into a USB 3.1 gen 2 port (1 of each @ 500MB, 1GB, 2GB, 4GB & 8GB). Speeds start dropping down the larger the test file was.
Speed breakdown for the images is as follows for those that were wondering:
USB 2.0 image is the read speed of 40.22 & write speed of 17.01
USB 3.0 image is the read speed of 126.2 & write speed of 50.41
USB 3.1 gen 2 images are the remaining 5 images as well as the windows copying images

Just for a test, I copied over an approximately 4GB video file to the drive via the USB 3.1 gen 2 port (see the windows copying images). At the halfway point of the file, the speed starts to drop off and never recovers. Looks like the video file maintained a good 64 MB until the halfway mark.

2.0 out of 5 stars Not durable enough for every day transfer use.
By Paul K. on April 16, 2018
The pros. Small form factor, and doesn't get super hot like the metal one.
The cons. It is made out of paper thin plastic. I had it come apart inside of the only USB port my Surface pro has. It was quite the challenge to fish the piece out without damaging my device.

I would only recommend this if you plan to install it and leave it. If like me, you need a portable device to transfer files from machine to machine, look elsewhere.

Really wish it wasn't plastic. After constant use it started to crack, then broke in my laptop. I needed to fish the broken pieces out with a blade. I am sticking to metal drives from now on as I am noy satisfied with this.

4.0 out of 5 stars Soddisfacente
Reviewed in Italy on November 3, 2018
Allego i benchmark e le prove effettive (su porta USB 3.0, non 3.1) che ho fatto per dare un'idea realistica delle performance di questa pendrive.
E' davvero piccola, ma dispone di un aggancio per cavi/portachiavi qualora aveste paura di perderla.
Dopo pochi usi si notano già delle strie di usura sulla plastica nera, ma una volta inserita nel dispositivo non si vedono nemmeno.
Durante l'uso si riscalda moderatamente.

In definitiva, un hard disk esterno ha prestazioni sicuramente migliori, ma se non andate troppo di fretta e vi serve una penna molto portatile e che non dia fastidio, questa può essere una giusta scelta, considerando anche il prezzo esiguo.

PS; se ti è stata utile questa recensione, per favore, fammelo sapere con un "voto utile", grazie!

3.0 out of 5 stars Preis Leistung akzeptabel - update
Reviewed in Germany on June 9, 2018
Dass der SanDisk Customer Care die gestellte Frage nach den Schreibraten nicht beantworten wollte, kann ich verstehen. Die sind nämlich - für einen USB 3-Stick niedrig. Aber für einen angemessenen Preis gerade noch akzeptabel.

Die Auswahl kleiner Sticks z.B. für Autoradios, die möglichst nicht aus dem USB-Port herausragen soll, ist überschaubar. Ich wollte auf jeden Fall einen Stick mit einer Schreibrate von 5 MB/s. Das ist hier noch gegegeben. Beim Schreiben grosser Dateien unter Windows bricht die Schreibrate allerdings im Verlauf des Kopiervorgangs auch auf ca. 8 MB/s ein.

Die Bilder zeigen zwei Tests an USB 3-Ports und einen an einem USB 2-Port und einen Test mit H2testw (an USB 3)

Update Oktober 2020
Habe nochmals zwei Sticks a 32 GB gekauft und getestet. Die Schreibraten haben sich im Vergleich zu meinem ersten Test zwar (deutlich) verbessert, könnten aber noch besser sein. Die Leserate hat sich ebenfalls verbessert und kann sich sehen lassen!

Test mit F3 write unter Linux, vergleichbar mit H2testw für Windows (also vollschreiben mit grossen Dateien und wieder auslesen)
Durchschnittliche Schreibrate: 14.71 MB/s und 14.61 MB/s
Durchschnittliche Leserate: 109.28 MB/s und 109.25 MB/s

5.0 out of 5 stars Nicht kompatible Hardware -> Flasche Meßergebnisse
Reviewed in Germany on November 7, 2018
Viele Rezensionen werden mit Messergebnissen belegt ohne die tatsächlichen technischen Daten bei den Testbedingungen im Detail zu erwähnen.

Es wird einfach USB3 erwähnt und aus. Das sagt mir immer noch nicht welcher Controller verbaut ist und ob der User den richtigen Slot ( einen von 10 verfügbaren?! ) verwendet hat.

Mein Test erfolgte am NUC8i7HVK i7-8809G, am vorderen USB 3.1 Slot.

Deswegen muss ich hier sagen, die beworbenen Leseraten werden mit 130,95MB/s sogar minimal überboten, die Schreibraten sind mehr als ordentlich für einen Stick bei der Kapazität in dieser Baugröße zu diesem PReis. Absolut zu empfehlen!

Reviewed in Canada on January 3, 2019
I had this installed in an old computer to increase memory, and to move some files to another computer. After downloading for 20 minutes it was already hot, plastic was already soft. I had to unplug the computer and remove the battery and wait for it to cool down. As you can see with the pictures, I had to cut it out from the port, since it was and old computer I was able to open and remove melted pieces and the port still works. I would rate this a -5, do not buy this, I do not want someone else to experience what I had to go through.

O Pen-drive atinge as expectativas de velocidade de leitura mas esquenta muito e velocidade de escrita varia, em arquivos grandes fica na casa de 15mb/s o que pra mim é lento se você quer passar algo de 25GB, o que demora cerca de *30 MINUTOS*
Comprei o pen-drve na intenção de colocar neles arquivos grandes de filmes em 1080p e 4K, recomendo que quem coloca arquivos superiores a 4gb formate o pen-drve para o formato NTFS.
Recomendo colocar no pen drive algum tipo de fita colorida para evitar a perda.
Segue nas fotos testes que 2 diferentes programas de benchmark.
