Long thread about the heat these produce on the SanDisk site http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Ultra-Fit-USB-3-0-Excessive-Heat/td-p/336404

One person claims to have measured the temperature and they exceed the (ambient?) temperature maximum stated, but I'm not sure if that operating temp means anything with regards to the actual device temperature.

I've also got a small USB 3 device like this which has the very same heat issue, I've never known if it's the device or the port I'm plugging it in to which causes the heat, or just the way it's meant to be due to the speed of the data transfer.

I suppose if you burn yourself you could probably claim against the retailer and the manufacturer and get back a lot more than the couple of quid originally paid - does that make it a super hot deal? :wink:

Edit: fixed a typo

Just been to both Boots stores in Hammersmith and alas they have all been snapped up.

£9 scanned in my local (shelf label was £22!!)

£5 in my local.

Thanks for sharing, I live nearby and use these flash drives to record on my TV.

So, what is all the controversy about....?

It could be that they are just too small to dissipate the heat. These were the first and last smaller flash drives that ive tried. My plan was to leave them in place permanently in my TV, laptop and router without worrying about them getting knocked and causing damage to the host device, but the heat just put me off. It may actually be that the temperature isn't an issue, but it didn't seem right to me.

I could understand them getting warm, but this was a significant step beyond that.

It's a shame, as the physical design is good and the transfer rates were suitable for what I needed them to do.

These Sandisk Ultra Fit drives get very hot when running at USB 3.0 speeds - to the extent that they can burn your fingers if you happen to touch the metal part. Try for yourself - make sure that it is operating at USB 3.0 speeds and then copy a large file to or from the drive - you'll be in for a shock ! Think what it might be doing to that host port it is connected to !
Although operating at USB 2.0 speeds they do seem OK.

I wonder if this is common with these thumb sized drives or just particular models.
Ive not used a USB3 thumb sized drive, but have an older USB2 Super Talent 16GB tiny drive and that can get very hot when transferring large data. Could it be that normal size USB sticks have space inside them and the electronics have air between the case and not in direct contact with your fingers, as opposed to the thumb drives electronics which are encased with the plastic that you touch and thus transfer the heat direct to your fingers.
Has anybody used a thumb drive that doesn't get uncomfortably hot when in use?

12.5p per GB

16/2=8gb per £1 or 50p per 4gb bargain. None in my local :disappointed:

Great buy...must work out at 50p per GB or something like that...bargain.

Drat! Hammersmith is near me... ish... and only saw this now hehe

Out of curiosity, I passed by the hammersmith store this morning to see if there were any left. There 4 or 5 of these USBs left on the hanging shelf when I got mine yesterday. There were none left this morning.

You'll have to go in store, I went to the one in Elephant & castle and they had some, including a pack of 32gb single and double for clearance. I went to the ones in Oxford street and Walworth Road, they had none, so gotta just check any boots for them in clearance shelf.

Thanks for letting us all know what you had to eat :smiley:

as this in instore only, maybe change the title and the link?

good find op, heat added

Whaaaa??! Wow great buy!
