Re: Ultra Fit USB 3.0: Excessive Heat

[ Edited ]

I have just ordered a few of these (in total I have approx 8 of these USB3 32GB and 64 GB)

They were selling cheap.

I too noticed excess heat.

Does anyone have a link to an official Sandisk posting, saying that we do not have to worry about data loss ?

I can live with burnt fingers, as long as I do not risk losing data already stored on them

Potential loss of data could have me jumping off a cliff (as a Scot would be bereft if he thought he could lose data after all of those purchases)

PS If the answer is - Don't worry Rob, you won't lose any previous data on the drive

THEN

I have a suggestion for all of those concerned about the heat damaging the computer and/or the usb socket.

Purchase a USB 3 Extension cable (Male into your PC, and Female socket on the end of the cable).

If you plug the sandisk into that, there will be no risk of damaging your PC.

 

Rob

PPS If the answer to my first post is - Rob, you could lose data.

I will take my own suggestion, and have a wee fan blowing on to the end of the cable

(If everyone PayPals me $20 for that suggestion, it could keep me away from the cliffs)

Re: Ultra Fit USB 3.0: Excessive Heat

I have the solution for you all.

I was using a usb3 extension cable and the sandisk 32GB was getting very hot.

(I previously had a sandisk OTG in there, and it too got frighteninly hot)

That cable had plastic shrouding over all of the female socket.

I looked through my previous ebay purchases, and found a 1M usb 3 cable with the female end bare metal (no plastic covering).

I tested the 32GB in it for 30 minutes, and just ejected it now, and it is slightly warm (NOT HOT)

I did not have any fan, and the room is 20C.

 

Another thing to be wary of, is ensuring you get a cable with a snug fit. For two reasons -

- I have had total loss of data when wiggle occured at a crucial time (mind you that was an external pocket 2.5" drive)

- A snug fit will help with heat transfer

 

The cable I previously purchased was most likely the same as this current ebay listing -

1M USB 3.0 Extension Data Cable SuperSpeed - A Male to A Female - AU STOCK

http://www.ebay.com.au/itm/1M-USB-3-0-Extension-Data-Cable-SuperSpeed-A-Male-to-A-Female-AU-STOCK-/2...

 

It was many months ago when I purchased mine.

I just rang the company, and they tell me that they have not changed supplier for 8 months, so there is a good chance that the current ebay listing (above link), is identical to mine.

 

Rob

PS I have just ordered some more, so I will report back to confirm whether they are the same. (should only takes days, as they and I, are both in Melbourne Vic Australia)

Re: Ultra Fit USB 3.0: Excessive Heat

Just bought the UltraFit 64G, inserted it in the USB of my desktop and loaded some files onto it, about 40Gb and sure....the thing became hot as hell. Really hot, the thing that at first amazed me as a nice piece of engineering wasn't, after all, that well engineered. Can't be good for the internals to get that hot.

Upon inserting it in the USBport of my laptop, and using it in a more normal way, the temperature was much more acceptable, just hand warm, so I guess under  practical conditions, making a report, watching a movie, everything is acceptable.

But big data dumps seem to be a problem, and I really also hate to see it use that much battery power from the poor laptop's battery.

I have a 32GB that seems to not overheat like my 128GB does. In any case the solution is simple - just use a USB2.0 port when writing large amounts data to it.

Re: Ultra Fit USB 3.0: Excessive Heat

Yesterday i tested a few of the "solutions" on this forum on my 64GB's.

 

First I attached a heat sensor of my (old) coolermaster aerogate on the side of tha flash drive and put in into a usb 3.0 port on the front of an icy box USB hub / card reader.

 

The sensor reached a temp of 55°C (131°f) max when reading or writing 40GB of data

 

Moving the flash drive to a USB 2 port didn't change the temperature. About 2 degrees. But still very hot. Even using an USB2 extention cable with an "open" connector didn't change anything.

Even when only idle in a USB port it was about 40-42°C

 

The idea of this type of flash drive is to keep in stationary in a device (it's so small you will lose if it's not permanently attached to something). But it is a battery drain! Tested it on a laptop an on my android tablet with an otg cable. On both of them it gets warm even when doing nothing.

 

OK it was cheap, but I have zero confidence in these flash drives. To be sure it won't damage my TV I put it on a logitech extension piece from a unifying receiver. Beter be safe then sorry

In that case, it defeats the purpose of buying a USB 3.0 flashdisk.

In my case I keep it plugged into a USB2.0 only device for music playback. While it would be nice to be able to wrte to it on a USB3.0 port I rarely do that now that I have it loaded up Smiley Happy .

Re: Ultra Fit USB 3.0: Excessive Heat

Hi, I removed the plastik and metal casing and inserted it into a USB port but the Ultra fit wont work and its not recognized. I was hoping the heat can get away much better like that. Is there some ground not touching when naked without its metal housing? The pins on the USB seem to connect fine when inserted.
