SanDisk Extreme Go USB 3.1 128 GB Flash Drive , black

Have had this product for 18 months and it never fails to impress. I use this every day for transferring files between laptops, PCs and colleagues. It has never let me down and has never slowed down. Its average transfer speeds are around 120MB/s higher if transferring single large files, slower if transferring lots of small files but rarely does the average drop below 100MB/s. For those people who score it badly on transfer speed I would suggest checking ports and/or drivers. Depending on OS USB3.0/3.1 is not supported even on a USB3 port unless you have the correct drivers. Generally in these cases you will see speeds more akin to USB2 or even slower. Yes there are faster sticks around now but bang for buck you can't really go wrong with this.

This usb drive is really fast - copying large files to the pen drive is done at close to advertised speed (141MBs) on my laptop. Reading is even faster - 172MBs on my machine, which is from 2012. It does have SSDs though, not the HDDs. The most important thing to me is that these speeds are sustained, they don't shoot up and down like with some cheap usb drives. The blue activity light is useful too. I had 3 older Sandisk Extreme drives and they were all perfect. The only thing to mention is I broke some old ones myself. They are quite large and I would pick the laptop in a hurry and bent them. They worked fine at first, but after a few months would fail. Not the issue with the drive, but my own clumsiness. Just something to keep in mind that they are a bit longer than most pen drivers, but then again they are faster than most. I would recommend these.

Sandisk, You did it again. Your fastest flash drives may not me physically small, but they always deliver in terms of performance. Design is exactly like on the promo shots: full-black with shiny strip and blue LED hidden underneath it. When the drive is connected, it glows in "breathe" mode and when you copy/read data, it turns into pulsing mode. The diode is strong enough to be easily seen, yet not too much which would annoy/distract the user. Simple, informative, nice looking. As for the case, aluminium would be more in place just for the sake of looks (temperatures aren't an issue here, at all), yet Sandisk keeps sticking with plastic. Plug's ejecting and hiding mechanism feels solid enough for many years of use and helps reducing already significant length of the drive. Speeds are exactly like promised: 150 MB/s write is in range synthetically or on many small files, while on larger files You achieve stable 100 MB/s. Overall: great pick for power users, operating on large amount of data and expecting highest speeds possible. While the looks can seem cheap (big size & plastic case), it's the components that count. And that's where the Sandisk smashes the competitors.

The Sandisk Extreme Go SDCZ800-128G-G46 USB3.1 sticks are nominal 128GB good speed devices with a fast interface. They are ideal for sending big chunks of data through snailmail in a jiffybag, and also where there is not a local high speed interconnect between machines. There was some clutter on the sticks taking up some valuable space when first examined, but I always reformat new media to remove any possible Trojans etc and NTFS is a more robust file system than exFAT. I also always test them to check for speed and capacity. At first sight the retractable plug is handy, but the contacts are still just as exposed to dust dirt and static. So in reality this feature is simply a gimmick and a waste of space, and these sticks end up being about 2cms longer than normal sticks which makes them more vulnerable to accidental knocks while plugged into, say, a laptop. H2TestW gave me an average write speed of 35.2MBytes/s and 57:12 minutes to write the whole chip, double the speed of the 128GB Sandisk Ultra chips, and steady between 35.5 and 35.0 all the way through. However, I have seen this test write between 95 and 105Mbytes/s on the older 32GB Sandisk Extreme USB3 devices on this machine, almost three times faster, so it is definitely the chip that is slowing it down. Read speed is much better, at 135Mbytes/s and 14:52 minutes to verify the whole chip, but still does not fully exercise the USB3 interface, and still slower than the 32GB which were about 168Mbytes/s. Storage is shown as 117GB available on the PC, actually 126,533,763,072 bytes, when formatted as exFAT with default sector sizes. NTFS has a slightly bigger overhead so slightly less available storage at 126,452,592,640. There were no bad locations on either of my two samples. The chip runs at about 15°C above ambient, nowhere near as hot as some I've tested, but then it is not working as hard. This is actually a good thing, because running cooler should maximise lifespan and reliability. I have specifically ignored the Sandisk encryption system because I don’t know anything about its provenance and also because it is an all eggs in one basket system. If it is unavoidably necessary to encrypt any files I’ll do them individually with software I know and trust, and give each a unique pass key.

One of my few but very best IT buys

Device tests to read / write at the stated speeds on some PCs. The initial ex-fat partition had to be re-formatted to ext4fs or f2fs to get the performance on linux, and write speed was quite a bit slower on a raspberry Pi 4b vs write on a Solidrun ARM PC / conventional skylake PC (read speed was just below 200Mb/s on all devices). Currently in use as the root drive for the Pi I've got running my DHCP server, syslog and SNMP server. Like night and day for system responsiveness even compared to a top speed SD card. Well worth it as avoided the need to buy another mini PC.

I recently purchased the SanDisk Ultra Flair 64 GB USB 3.0 Flash Drive from Amazon and returned it immediately after getting very slow write speeds. I then took my time and found this. It boasts fast write speeds. I received it and tried it and got a constant speed of 132mbps. This is what I want from my flash drives. It's always better to pay a bit extra if you are looking for fast write speeds. The drive itself looks great and was instantly recognised when I inserted it. Hopefully it will last me a long time. Only time will tell.

Als ich den Sandisk 64 GB Stick entschieden habe zu kaufen, war mir ein bisschen unsicher, da die Top-Rezensionen nicht so gut sind, aber glaub mir, der Stick ist völlig in Ordnung. Die Schreibgeschwindigkeit entspricht wie angeboten (im extrem Fall natürlich). Allerdings konnte ich die Lesegeschwindigkeit sogar in extrem Fall nicht die 260MB/s erreichen, nur bis 200MB/s. Dennoch ist insgesamt ein sehr guter Stick, es kommt auch mit dem SanDisk SecureAccess, obowhl ich noch nicht benutzt habe, denke ich für den Alltag sensible Daten zu verschlüsseln, ist völlig in Ordnung. Es hat auch einen RescuePRO Key(1-Jahr-gültig), mit dem man Daten retten kann, habe aber bis jetzt nicht benutzt. Es könnte auch ein bisschen billiger sein, denn für den Preis würde ich schon mehr Leistung erwarten. Ich habe auch Bilder hinzugefügt, mit verschiedenen Tests und verschiedene Version von Programmen wie ATTO und Crystal Disk Mark und Windows Selbst. Nur als Info, mein PC ist relativ gut, mit Core i9 und nur SSDs, also die fehlende 60MB/s von Lesegeschwindigkeit ist nicht wegen des Performances meines PCs.

The 128GB version of this is the "upgrade" pick from Wirecutter for flash drives, except it's only $4 more than their normal pick, at 64GB. 128GB in your pocket for only $32 (at the time of this review) is really ridiculous. The transfer speeds are very fast. I don't bother doing my own benchmarkings--google them if you care, but they're very good at USB 3.1 rates. I really like the sliding & locking mechanism to protect the USB connection. Bigger than a thumbnail sized drive, but small enough to put on my keychain. The included (for free) encrypted drive system is easy enough to use. Its GUI a bit clunky to navigate, but to launch it, just double click on the .exe file that's on the unencrypted partition. It uses the AES 128 synchronous cipher, which is more than strong enough for most needs. It looks like you can upgrade it for a price, but you can also store your own end-to-end encrypted Trucrypt or Veracrypt "file" (volume) if you're that paranoid.

Ya tenía tiempo que quería una USB 3.0 de gran capacidad y prestaciones de lectura/escritura que fuese asequible, porque suelen ser algo caras. Afortunadamente tuvo un bajón de precio ésta memoria que estaba siguiendo que no lo dudé y la compré. La utilizo por lo general en guardar películas 4K para visualizarlas en un BluRay UHD, ya que lamentablemente no hay manera de grabarlas en disco por su capacidad limitada al ser la mayoría películas arriba de 60GB y no me ha defraudado para nada, no se traban y la transferencia de la PC a la USB es realmente rápida. La recomiendo si buscan guardar archivos grandes en poco tiempo.

Cumple con lo que promete, excelente memoria y rápida muy recomendable

Me fié de la mayoría de las opiniones, buscando especialmente velocidad y he acertado... por fin! El mayor uso que le doy es el de meterle películas para luego verlas en la smart TV. Bien, pues va de lujo. Hace poco cambiamos la torre pc que ya trae puertos usb 3.0 y compré un pendrive 3.0 barato, de otra marca y menudo timo! Este me ha costado más del doble - aunque con 64Gb- y da gusto verlo pasar archivos a 132 MB/seg. de principio a fin. Vamos, que le meto tres pelis de unos 7/8 Gb en total y vuelan... al menos comparando con todo lo que he conocido hasta ahora. Se calienta un poco al pasarle archivos, pero como al ir tan rápido no tarda, no le doy mayor importancia. Me gusta el detalle de la luz azul y el mecanismo de la pestaña que saca el puerto queda fijo perfecto, no como otros que he tenido que se metían un poco al enchufarlo al puerto. Espero haber sido útil a quienes buscan información y lo recomiendo sin dudar.
