That's why I recommend sticking to reputable brands, paying a reasonable / fair amount of money for them (if it is unbelievably cheap, be very, very suspicious), and try to only buy from very reputable sellers / sources.
I once got two of 8GB sticks similar to this one. Philips, no shit. Bought from a well-known supermarket, not just ebay or brocante.
This is how dmesg sees it:
[46580.392980] usb 1-5: New USB device found, idVendor=abcd, idProduct=1234, bcdDevice= 1.00
[46580.392986] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[46580.392990] usb 1-5: Product: PHILIPS
[46580.392994] usb 1-5: Manufacturer:
[46580.392997] usb 1-5: SerialNumber: Љ
This is wrong in more than two places ![Face Palm :palm:](https://www.eevblog.com/forum/Smileys/default/xfacepalm.gif.pagespeed.ic.EBDwh1hCfo.png)
I intentionally avoided mentioning brands, as it can cause arguments, and the best ones to get, may change over time.
I'd worry that a Philips branded one, would be out of the range of stuff, Philips's usually do. So, it might really be a generic and rather cheap USB pen stick, and hence not of particularly good reliability / quality and so on.
Some of Philips's stuff is made by themselves and good quality, but some of it, is not so good. A bit of a mixed bag.
The top tier, (best to check from quality information sources, so I could easily be out of date or wrong), is probably things made by SanDisk, Samsung, Corsair (not necessarily all of them, but the top priced ones, possibly), and I might have forgotten about others.
A lower tier, but still of good and reasonable quality, might be Kingston, which are usually good, but maybe not the fastest.
I also like to check the review star ratings (as being top notch) and only buy from 100% reputable sellers, such as Amazon (usually good / safe).
Common rumors are that, they cream off the top and most reliable (best) quality flash chips for things like SSDs, and lesser quality flash chips, are used for flash USB pens. The cheap, unbranded USB pen sticks being, often rumored to be made out of failed, bottom tier, flash chips (rejects). Which can easily have faulty flash memory, whose faults tends to grow and get worse, over time.
Anyway, flash memory (in general), tends to lose its contents over time (hopefully decades, but modern stuff is rumored to have much less generous life times, such as 12 months, only, in some cases). Which can be annoying.
I sometimes worry about the somewhat disappearing (year by year) hard disk drives. Because they at least (as long as they work), don't generally suffer from memory fade, over time. Pity viable and modern alternatives to flash memory types, don't seem to have appeared.
But there are still hard disk drives, bluray discs, archival (special 100 year or similar life types) storage bluray/DVD types and tape drives (if you can afford it, cope with their difficulties and find them available).
