File transfer speeds in MB/s or KB/s please!

I just transferred 212GB of GoPro videos (flying lessons!) to a 256GB stick and it took about 2 hours and 45 minutes, which, if my math is reasonable, is an average of 21MB/s. It would stop, then ramp up to around 120MB/s, then ramp back down to 0MB/s and sit there for a few seconds and just keep cycling back and forth between fast and stopped. Pretty terrible. I then transferred the same files to an external hard drive, to make sure my USB port wasn't acting up and it transferred at an average of 95MB/s and it never dropped below 80MB/s, so I do believe it was just this flash drive. I'll probably be sending it back, since this seems to be a common problem with them, based on these other comments.

I purchased three of these, assuming since they were 3.0, that they would function reasonably fast in a 3.0 port. Unfortunately, I found that not to be the case and, as another reviewer noted, the speed seems to be quite inconsistent. I now use them only for situations where file transfer speed is not critical.

For those of you who have owned it for 6+ months, how's the reliability? I've seen reviews on other sites where people say the drive has failed them.

I use them for 3d resin printing. The first 20 i ordered about 5 months ago and are used every day almost 24/7 No issues. I JUST bought 3 more packs, and 3 out of 5 (in each pack) of the USB fail mid way though a 4 + hour print. I assume they changed -something- but these are unreliable for my business now.

are these safe from hackers?

Any human made item will have bugs and flaws in the design. Nothing is 100% safe from hackers.

Great little product

Arrived promptly (ten days from order to delivery) and in good condition. We've now ordered two of these USB flash drives. The first worked perfectly. Highly recommended.

Cheap and works fine

No problems. Cover is a bit stiff, and it lacks a bit in style, but that's not really an issue for me.

Very slow read/write speeds - DON'T BUY!

I bought two 64Gb PNY flash drives in 2015. I thought I was buying the same or better product when I ordered this product, how wrong I was! This product is slower than a snail. It took 3hours to copy a 28Gb folder on a 2015 MacBook Pro. The older and faster drive took only 45 minutes to do the same job. Please avoid this product, it's rubbish :(

poor

Video files freeze for 5 seconds every few minutes when played on a tv. Tried 2 different tvs, tried reducing the amount of files on the drive, didn't work.
