Temperature of USB drives during use:

What are the temperature standards for USB drives?

Temperature testing:

SanDisk USB drives are designed using the Safety of Information Technology Equipment, IEC 60950-1 as guidance. Many countries, including the United States, Canada, Europe, Australia and New Zealand, have adopted this safety standard.

In accordance with this guidance, SanDisk USB drives are tested to operate within acceptable ambient temperature ranges (0º C and 25º C). Our drives are also tested in an extended temperate range and will operate in environments between 25º and 45º C.

Factors that may increase drive temperature during use
External environment & host device

In environments that are on the higher end of the tested temperature range, such as 25 º C – 45º C, it is normal for the temperature of your flash drive to increase. The exterior of the drive functions as a cooling surface that transfers heat from inside the drive to the cooler air outside. If the temperature of the ambient environment is high or if the temperature of your host devices (such as your laptop which can also generate heat) is high, the drive will release heat in a less efficient manner. It is normal for the drive to be warmer in these circumstances than it would be if the ambient environment or host device was cooler.

· Large file transfers & extended usage

An increase in drive temperature is also normal if you are using your flash drive to transfer large files or multiple files. Large file transfers may take an extended period of time to complete and can require more energy than a small file transfer. Multiple file transfers that are completed over a short period of time can generate a similar amount of energy. During these drive operations, the interior temperature of the drive increases and the drive will release more heat through the drive’s exterior in order to complete the data transfer.

· USB drives with metal material

Metal absorbs more heat than plastic materials. Metal also releases heat when touched at a faster rate and may feel hot as compared to drives made out of plastic materials that are being used in the same way. SanDisk iXpand flash drive, SanDisk Ultra Fit USB, SanDisk Ultra Flair USB, SanDisk Ultra USB Type-C, Cruzer Force USB and SanDisk Extreme PRO USB flash drive products all incorporate more metal material than other SanDisk USB drives.

Any of the above factors may result in your drive running warm, if you experience this and find the elevated temperature to be uncomfortable, please consider waiting 10-15 seconds after your transfer is complete to remove/eject the drive.

Good but heats up quickly Works fine but heats up a bit.Works out of the box on Android phones. And it’s USB 3 and not USB 2, so the speed is a good.A lot better than purchasing cheap USB OTG adapter and plugging normal pen drives. But it’s also good to have a OTG adapter in your arsenal since you might need to connect a normal pen drive some day.But the problem is it is very small and so, it heats up pretty soon.

Totally worth the price. Firstly surprise to see this miniature at this price that is Rs. 649 bought it two days ago and it arrived today. I started testing this pendrive and i was totally shocked regarding its read and write speed.results -1. copying 1.8gb file from laptop to pendrive speed = 40mb/s average2. copying 1.8gb file from pendrive to laptop speed = 290mb/s average3. cut-paste 2.8 gb file from laptop to pendrive speed = 43mb/s average4. cut paste 2.8 gb file from pendrive to laptop speed = 80mb/s averagep.s (All these results are based while using pendrive in 3.0 usb slot in laptop.)Also you have to put your finger for support behind the handle to push the p.d into the usb slot otherwise it will slip backwards.

GOOD OTG PENDRIVE! I have been wanting to get an OTG pendrive since long and after a long search i settled on to getting this one. It a good little pendrive. Working fine with my phone also the slide lock mechanism is working smooth so far. Although i feel it’d break if not used properly. Speed is okay not very fast but i got it on a lightning deal and it is doing its job fine so i guess its a good buy for the price. Transfer speed is a bit slow like other reviewers have mentioned in their reviews. It even heats up. But overall a good experience with the product and Amazon both.
