A great flash drive. I'm on my third unit, and two of them have worked very hard and are working as they did new about 1,5 years ago. The newest one has revised firmware with additional SMART indicators. Old has 13, new has 15. Both seem to behave similar though.

- tested on Lenovo ThinkPad Yoga 11e, 8 GB RAM, writing direct from SSD to USB 3.0 port - CZ80 was re-formatted to NTFS - files written were 3 GB+ AVIs and MKVs

fast...VERY fast; compared to previous 45 MB/s write speed with SanDisk Ultra CZ48

21% less than advertised 190 MB/s write speed

I have used the 16 GB version of this drive before, and I like it. This 64 GB drive arrived damaged, which I am quite sure, was during the manufacturing process and no fault of the seller. SanDisk says that they will send me another one, with very little hassle on my part.

The product speaks for its self.. you need fast transfer rates and live a busy life this is the ideal USB key. Quality, style and duarabily all meet a 5 star rating

Excellent Speed, Good Built Quality Writing speed is much much faster even in USB2.0, when compared with other USB3.0 pen drives... and if u r connecting it on USB3.0 port, enjoy the speed ! Go for it !!!!

Very impressed, can run an operating system easy off Sandisk Extreme USB3 64GB stick...

Very fast responsive..; usb2 max speed, usb3 faster than sata

The shape maybe

Does everything it says it does and more.

Easy To Set Up; Easy To Use; Fast; High Capacity; Portable; Reliable

This product is excellent. It is very handy and very quick performance. I highly recommend it.

I thought I had lost my 2 week old Extreme USB drive, but it turns out it had just been in the pocket of my pants when they went in the wash. It got trapped in the front lip of the washing machine, and blocked the drainage hole.

* Survives a month trapped in the washing machine * Decent speed

* Slide mechanism isnt amazing

Transfers files, etc.. so quickly - so glad I bought it.....

I find using the Dual USB Drive 3.0 is great for freeing up space on my computer and so easy to move files; photographs; etc..
