SanDisk 512GB Ultra Fit USB 3.1 Flash Drive Up to 400 MB/s

RescuePRO® Deluxe file recovery software 4 helps you restore files, even if they’re accidentally lost or deleted. How can Sandisk get away with this - even allowing for the industry norm of dividing by 1000 (and not the correct 1024) to convert from bytes, it’s not even 64000 !!! url=https://usb.userbenchmark.com/SanDisk-Ultra-Fit-USB-30-64GB/Rating/2698]Userbenchmark: SanDisk Ultra Fit USB 3.0 64GB SDCZ43-064G-G46[/url] Please see this link below for the image for such vents/cutouts. There are 2 on each side of the sheet-metal.

Thank you!

Depending on the workload you ahve running on these machines (data logging especially) you may simply be wearing the drives out. as far as i could research the heating case for the ultra fit i found out that its becoming so hot because of the small size of the drive and that its not plastic. I also noticed right after I plugged the flash drive (Ultra Fit 3.0 - 32 GB) for the first time that it got insanely hot, even after transfering files from or to the device and having it ejected. This happened in every port in my desktop computer, 2.0 and 3.0. However, I brought the flash drive to work this morning and transfered over 25 GB to my work desktop (2.0 ports only). It took about 8 minutes to do it and it didn’t even get a little warm, nothing, which suggests that the problem has something to do with the ports the flash drive is connected to, and not only the the drive itself. The Verbatim branded thumbdrive get really hot(whole body is aluminium) even if plugged into smartphone after prolonged use.

With capacities up to 512GB 6, you can store more of your critical files and important photos, videos, and more.

I found this same problem. And the main reason is that it poorly designed when compared with Cruzer Fit. I bought the 64GB Ultra Fit to use as extra storage for my Chromebook. After leaving the Ultra Fit in either the USB 2.0 or 3.0 slots for a mere 5 minutes it gets considerably hot. Even AFTER ejecting the drive and leaving it in it is still getting hot. In the 3.0 slot it gets so hot you don’t want to hold it.

the level of overheat is ridiculous! this is a design issue for the ultra fit not a isolated heating problem with some units only. I know this is a rather old thread, but I wanted to post my experience with this device too, as it is a little different from yours (and nearly everyone).I can concur. My 128Gb Ultra Fit runs too hot as well. To the point where it begins to disconnect and reconnect constantly. The only solution is to cool the drive down and resume operations. However it only takes around 5 minutes of copying before it begins to exhibit problems. Designed for plug-and-stay storage, this compact flash drive works with laptops, tablets, TVs, gaming consoles, car audio systems, and more. Plug it in, and you’ve got instant storage that’s always available! Reading and Writing to the Ultra Fit on my Acer laptop didn’t have any disconnects, but the metal part did get really hot. I’m wondering if this is due to the LED in the case that is constantly (24/7) blinking and drawing power? Maybe this was designed to only blink when read/write???

And came to this forum by searching ultrafit exesive heat after transfering 5 1,5 gb files first through a usb port, then through a USB 3 hub.Based on read speed. 1 MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors. USB 3.0 port required.
