The metallic construction is deceiving and looks quality, if I had read the reviews earlier I wouldn't have chosen it, I bought it as an emergency solution from a physical store! It doesn't connect well to the USB-C and often disconnects by itself without completing the file transfer. Very bad!

the worst, what can I first comment on that out of the 64 gigabytes it gives you 58.5, it eats up 5.5 gigabytes, in terms of performance it is literally a turtle and for those in the know it does not support format type fat 32 meaning if you have a pioneer radio it will not read it at all it will give error 32 and definitely on any other device that requires this type, really useless, a waste of the 15 euros I paid

I got it for the simultaneous presence of usb-a and usb-c it has (connection with android phones, new and old PCs/laptops). The previous one of the same philosophy I had (ADATA) while it was good in speeds eventually suffered a hardware failure (the usb-c came off the board, the type-A worked normally). I have the Intenso 32gb for a few days so I will talk about "first impression".

- It is FAST.
--- In usb 3: writing speeds of "large file" 2.5gb iso (seq write) = 45mb/sec, Read (seq read): 164mb/sec. See "images" for behavior (there is an initial buffer that makes it faster). The test concerns a win 11 machine on ryzen 5 3rd gen, ssd m2.
--- In usb 2: write 18mb/sec, read 32mb/sec (which is close to the maximums of the protocol). The test concerns a win 10 machine on i3 2nd gen/ ssd.

Obviously, when copying many small files, the speed drops significantly as with everything (comparatively it remains fast).

- It does NOT get very hot.
Generally for "small" copies (write) let's say 2gb it comes out "warm" now that it is spring (in the summer and for larger copies it will definitely be somewhat worse). In usb-3 type-c it gets a bit warmer I think and after use it comes out quite warm but nothing compared to "burning" (which I have seen some kingstone and others). In usb-2 it heats up even less. This is important for the life of the material in theory at least. For large copies of many gb I don't have an opinion anyway in everyday use for regular file copies I don't consider it gets very hot.

- It is a quality construction.
It is all-metal without painted plastics in metal color. It rotates with a click (4 positions) meaning it will not rotate freely. On the keys, it shows that it will survive (the plastics suffer). There are reports on amazon that in some cases the "board" came off the metal casing and the memory/electronics came out. This is common for some reason in metal flash drives mainly and may have to do with their contractions/expansions and the glue used. It happened to me with the older ADATA where I glued it with new glue that I put in a neutral spot and left it on a usb port for one night. It did not come off again. The risk here is that your flash drive "might go" and you lose it and can't find it again (you are left with the casing on your keys). If you see it (meaning you don't lose the inside) you can fix it with "kindergarten" skills (it just needs a bit of glue, probably a hard glue not gasoline glue unless you want to take it out again).

Observations.
Sometimes it didn't "catch" well in the port I was putting it in resulting in various quirks like very slow writing speeds (with type-c more easily). The ADATA I had was better in this (I had no issues it didn't sit well). This may be the reason some say it doesn't have good speeds while the flash drive is very fast as you can see in the images.
The type-c plug on mine is not 100% straight (it looks a bit crooked, at least after 1-2 insertions that I looked at and noticed). I'm a bit afraid it might come off like the ADATA.

For its durability, we will have to see. WE NEVER have our files only on a flash drive. They can burn or get lost and should only be used for file transfer and not as the only storage space.
update 4/4/2025
It continues to function normally to this day from both A/C ports. At some point when it became "slow" I reformatted it and it returned to the initial speeds I mention (it was a software issue related to many pulls without "removal"). In all the flash drives, from time to time we clean the type A with some clip to remove dust, etc., so that the connection is not lost. While it may need to be pushed in and out a bit in some ports to be recognized. Nothing unusual. Sometimes under pressure it unclips from its "cover" where it rotates, but it was easily repositioned. The clips a little (you press it) to not come out again.
Conclusion so far, I am very satisfied.
P.S. I reiterate that the speeds I measure pertain to the **32gb** version, not larger ones that may have other memory chips and thus different speeds and behavior regarding heating, etc. Do not assume the behavior is 100% the same. For cars, up to 32gb can usually be read in FAT32, so do not buy larger ones unless you know your vehicle supports them (the newer ones, for example).
