Question 1

Why would anyone buy this one over the older model considering that the older one is faster in both write and read speed?

Accepted Answer

Only O-N-E good reason to buy this over the older version; YOU CAN'T BUY THEM ANYMORE!!! The old CZ80 was far superior in performance particularly in writes, and out of the 5 64GB USB 3.1 models I bought all of them fail to even max out USB 2.0 on WRITES. On reads they perform about like a fixed mechanical HDD 80-120MB/s. What good is a USB 3.0 drive if you can't write data quickly as well as write it? You buy USB 3.0 flash drives to avoid staring at a progress bar forever! The thing that kills me the most is that Sandisk is more than capable of producing a quality product, but they have chosen to cheap out on the construction of some if their products lately in the interest of maximizing profit. If the old flash drives before these had become more expensive to manufacture they should have proportionately increased price because even if they charged 10-15 dollars more than what the drives were going for the CZ80 drives were still worth it at that price point; just look up some of the benchmarks for the CZ80. I ended up purchasing a Corsair Voyager GTX which is expensive, but at least it's performance and build quality are representative of what you expect at that price point.

Question 2

Your avertising shows a lifetime limited warranty but when searching through your q&a section i see a numer of different answers. so which is it?

Accepted Answer

all I know is I tried to return mine after 4 months and couldn’t.   It was dead after dozen uses.

Question 3

Is it good with nvidia shield tv?

Accepted Answer

I'm not sure. Idk what nvidia shield tv is. You can always google it or call SanDisk customer service.

Question 4

For people finding the write speeds slower than advertised, what competing drive has good write speeds?

Accepted Answer

I do not know. It's fast enough for my needs but I only use it for document transfer.
