Because the thumbdrive gets unusually hot, I measured current with USB current meter. I connected usb current meter to USB 2.0 port, and connected SanDisk Ultra Fit 16GB on the other side.
When the thumbdrive is in idle, 0.06A is constantly measured.
When the thumbdrive is in active, measure current fluctuates between 0.16A and 0.10A, so the average current looks to be 0.13A.
The power consumption rate of the thumbdrive is P = VI = 5.04V x 0.13mA = 655 mW. Because the power mostly dissipates as heat, the power consumption rate can be regarded as heat generation rate. If you are an electrical engineer, you can find that 655 mW is quite a high power for the small devices as thumbdrive. Note that the power limit of a normal resistor used in breadboard is 1/4 Watt. The power consumption of the thumbdrive is twice to the allowed power consumption of a normal resistor.
Furthermore, my computer is equipped only with USB 2.0 and the above current measurement is implemented in USB 2.0. In USB 3.0, much more current will flow through the thumbdrive, generating even more heat and increases temperature further.
High temperature in thumbdrive means shorter lifetime. Thus, I recommend this product for occasional use, but not for continuous or extensive use.
Precursor - I use SanDisk USB keys exclusively for work and car audio. I also use their SDHC Ultra cards exclusively for my digital photography. They are (IMHO) the best on the market. That being said - my review of this item.
First - when it is in-use - I mean really in use - like a large or numerous files - it gets HOT - Way hotter than the 35 degrees celsius (95 degrees F) that the SanDisk people refer to in the reviews...hot enough that you cannot touch it for a few seconds (again where the SanDisk people say to let it sit for 15-20 seconds before touching - Why???). After a large file transfer, it cools quickly. When using it in an auto receiver - it does not heat up as the data is randomly being accessed in short bursts. That being said - it does get hot. The older USB-2 versions (Cruzer Fit CZ33) does not get hot. Guess the data moves so fast that it scorches the copper pathways.
That brings me to the second point. USB-3 quickness. It is USB-3 quick on the transfer start but it slows down relative to the heating of the USB key. The hotter the USB key, the slower the transfer. When transferring 12gb data, it got very hot - stopped transferring for a minute (the USB key cooled down) started up quickly and then slowed down again to a crawl and finally - stopping again for the key to cool. I was able to do this on a laptop, desktop and MacBook - same results with all three so it is not a computer issue. So - is it USB-3 quick? Yes - until it overheats and stops to cool.
Third - Car stereo. Works like a champ! No issues at all. I have about 80 CDs on the key, roughly 12 songs per CD. It plays properly, is small enough that it does not stick out (The older Cruzer Fit CZ33 fits even closer to the faceplate of the car's receiver) and does NOT get hot. Minimal data transfers fed to the buffer of the receiver means that the key is not being pings as heavily and does not overheat. I have no issues at all with playing back MP3s on my receiver. But - I replicated the 'not playing' issue. My receiver only supports 128 folders (albums) of data. For giggles, I put 140 folder on the key and fired up the receiver. It failed to read the key. I pulled 12 folders off - leaving 128 and it worked fine. I added one (making 129 folders) and it worked sporadically. Not saying this is the cause for all - just something I noticed.
So - Three stars...
Quick on short bursts
Plenty of storage
Works great with car stereos.
Overheats on large transfers
Slows down when overheating
SanDisk support - No need to tell me to "open a case" - it is obvious that this USB key has flaws (just look at how many people report the same issue). Redesign or get a firmware fix. Not the usual SanDisk quality I have come to expect.
I attached some photos to show you guys how hot it gets after being connected to my laptop for 3 minutes (117.3 F or 47.5 C).
Given that it overheats in such a small amount of time, I recommend not to leave it connected to any USB port for more than 30 minutes, otherwise I think your data might be at risk.
