There was a problem filtering reviews right now. Please try again later.
The second problem is that writes are slow, painfully so for small files. I should have paid more attention to the reviews here stating this fact.
After doing some research, I bought the SanDisk Extreme CZ80 64 GB flash drive as a replacement. It runs much cooler, and the write speed is 5 times as fast for large files and 20 times as fast for small files (this is with both drives formatted as NTFS). I was even able to pick it up on a Daily Deal for only $7 more than the Ultra CZ48, but even if you have to pay twice as much it's worth it in my opinion.
I don't recommend the Ultra CZ48, but I highly recommend the Extreme CZ80.
Ran a disk benchmark on one drive, it went into "write protected mode" right afterwards.
Tried the second drive and tried to format to NTFS, failed and went into "write protected mode" as well.
From Sandisk's knowledge base:
"Write protection errors occur when a flash drive detects a potential fault within itself. The drive will go into write-protected mode to prevent data loss. There is no method to fix this. "
Here are the benchmarks ran before the drive failed:

Sandisk Ultra USB3 16GB
The one negative I found, which is the reason this is a four-star and not a five-star review has to do with the software on the drive. There is an executable that I believe has to do with drive security. When I ran it, it recognized that there was an update for the program, downloaded the update, but then the update would not run.
I paid full Amazon price for this flash drive. I wrote this review just to try to help others learn a little about it. I hope you found this review helpful. On the other hand, if you did not find this review helpful, I’d be interested in hearing why, so that I can attempt to edit it and make it more helpful to both you and others. If you leave a comment on the review, suggesting how it would be more helpful, I promise to respond to your comment, and to attempt to incorporate your suggestion in my review, if it is at all possible for me to do so. My goal is to write reviews that help people, as I have been helped by the reviews others have written. Thanks!

Sans signe avant coureur,ni avertissement préalable, ma Clé USB 3.0 Haute Vitesse SanDisk Ultra 128 Go s'est bloquée en mode écriture,donc plus moyen d'effacer les éléments qui s'y trouvent ou d'enregistrer de nouveaux éléments !
j'ai contacté par écrit le site officiel de SANDISK pour obtenir la solution préconisée par SANDISK pour débloquer ma clé USB:aucune réponse ne m'a été adressée ! J'ai lu attentivement les préconisations pré-écrites de SANDISK et ai constaté qu'une"ligne"traitait" le problème ..."une clé bloquée en écriture ne peut être débloquée" !
Faute de réaction de SANDISK,je demande à AMAZON de faire en sorte que je sois remboursé ou que ma clé USB SANDISK soit remplacée...pour les suites utiles et merci d'avance
Pros: light weight, huge storage, small size, fast read speed.
Cons: Slow write speed, write speed fluctuates, build material is not good feels thin and low quality plastic.
This doesn't fall under pros or cons and that is actual usable space available is only 114GB.
If you want huge storage with only fast read speed (I would suppose, you don't), and light weight pen/flash drive, then this is good option for you.
But, if you want fast write speed along with huge storage, then this is not a good choice.
I have recorded the video with write and read speed, video went long because of slow write speed.

Tengo otro Sandisk similar de 64GB que compré en Amazon hace más de 3 años y sigue funcionando perfectamente (tiene el led que parpadea, el color frontal de la conexión del puerto usb completamente azul y la velocidad de transferencia mucho mayor), además he podido compararlo y no hay color.
No entiendo como Amazon puede vender algo falso, esto me genera desconfianza, pues compro bastante por aquí. Debí hacer caso de las advertencias en los comentarios.
1.) The USB 3.0 connector is very tight and I have had a real struggle fitting it in to several of my devices.
2.) Because of the tightness of the connector the slider/catch that holds the USB head forward is almost
useless and occasionally gives way and allows the head to be pushed back inside the body when being inserted.
So I now have to hold the slider forward with my thumb whenever I'm trying to insert it just in case it's pushed back.
Of course the USB connectors on some devices are upside down so I have to do this from underneath the drive.
It's ironic since some of my older USB drives had sliders that were way too stiff to move back and forth frequently.
So I'm now looking for USB thumb drives that don't have any sliders. They never work well!
As other reviewers have observed, the constant speed attained [after an initial false high!] is 15 to 20 MB/sec.
Clearly, this is NOT a USB 3.0 device and a waste of INR 798.00 !!
It is light weight and has an activity LED but you can have these functions on older devices as well. I expected the same 'advertised performance' as on my many SanDisk microSD cards but I am extremely disappointed.
Eventhough, there was a return window for this item I didn't have the time or the inclination.. to go through the process.
You are better off buying a standard USB 2.0 and save money rather than purchase this FAKE USB 3.0 !!
The amazon delivery for this product was fastest for me as a prime member. I had ordered it at 11:30 pm and I got the delivery at 11:30 am on the next day.
Al introducir el usb me salta un error:
"No se puede obtener acceso a H:\.
El medio está protegido contra escritura".
Consultando soluciones y comentarios de otros usuarios, a parte de descubrir que no tiene solución, me he dado cuenta que hay modelos que tienen led de estado, mi unidad no tiene y temo que sea una falsificación.
En fin, ya voy tarde para devolverlo, pero espero que mi comentario sirva de ayuda a otros usuarios con el mismo problema.
I couldn't see any benchmarks for the 128GB version, so see attached images.
Real world Windows 10 test: A Windows 10 ISO (6,800,801,792 bytes), took 2m55s to write to the drive using TeraCopy.
Capacity: 123,010,527,232 (NTFS)
Capacity: 123,005,179,760 (exFAT)
The hole cutout doesn't feel particularly strong. I was going to put a metal ring through it, but it feels weak. Threading it through a lanyard gives me more faith it'll last.
My two stars are only for reading speed. Please donot cheat the customers. In your description it is given as 10 times than 2.0 but its not.
This means :
1. Cannot retrieve my files - lost forever
2. Cannot format to reuse the disk
And I though these would get lifetime support being a sandisk... but no.
I got the 128Gb version and now have freeview recording capability and aroudn 100hrs of capacity. Not exactly relevant but the native Sony software works great to setup and manage recodings. The TV tested the speed, formatted and registered the device, and it was ready to go with recordings and live TV pause and rewind.
For the price it was a no brainer. I might even get another one to backup my NAS files for easy travel.
