Re: Ultra Fit USB 3.0: Excessive Heat

I believe the concern is the laptop USB port it is connected to as well as the data in it.


Replacement only cover the USB Flash Drive, not the data neither the laptop USB port (if it is damaged due to overheat from the USB Flash Drive).


While other manufacturer also does not provide any warranty to cover the data (in case of loss) neither the USB port of any laptop, however, the USB Flash Drive from other manufacturer does not operate under that high temperature (at least the temperature of the touchable surface of the USB Flash Drive).


The workaround is to use extension cable, but other's opinion is also valid as like why should I buy a tiny USB Flash Drive but end up with attaching an extra USB cable? It against the tiny design!

So, its been a while, and I'd like to comment back on this USB. I've had it for over a year, run several Linux distros on it, and currently use it to store ROMs/Kernels/Flashables for my Nexus and Galaxy phones- in short, it works great as small expandable storage.


As a USB 2.0 device, that is. I'm highly disappointed in the heat department when used as a 3.0 device, but for such a small USB and form factor I'm not surprised. When I need to get stuff done, 3.0 does the job but man, the heat is insane.

Even so, USB 2.0 speeds and heat development are actually very decent. Read is around 70 MB/s while Write is around 50 MB/s. Nothing blazing but plenty fast for any self-respecting Linux distro out there. Heat is no problem when connected to a 2.0 port- for a few months I was running Steam games daily from it.


So overall, for the $11 I spent for this little guy I'm satisfied. I think Sandisk ought to inform customers, however, as there are many people in this thread who haven't had nearly as rosy an experience as I.

Re: Ultra Fit USB 3.0: Excessive Heat

i would like to share my experience with Ultra Fit 3.0-16GB.I've used it in my Sony Car Audio System. But after few months i've found the heating issue. It became so hot just few minutes after inserting that couldn't be touched on the metallic portion.Few months later it started showing problems like, the flash drive is undetectable after getting heated just after inserting it. It becomes a useless one. SanDisk should solve the problem or stop selling this product.
