Netac 64GB USB 3.0 Flash Drive Up to 90MB/s Thumb Drive for Data Storage, Pen Drive Write Protection with Push-Pull Design Memory Stick for External Storage Data/Computer/PC/Laptop/Sound-U335S

Product works as advertised.I submitted another review before saying it didn't work, but that was due to a faulty USB hub or something else. I switch to another computer and the USB works as it should

I have done computer consulting of some sort for many years. I have always kind of worried about transferring viruses between computers with USB flash drives. I was introduced to Kangaroo lockable flash drives at work. They are great, but costly. These drives have all of the lockable USB functionality for a fraction of the price and a well constructed plastic housing to boot! I have a few of these on hand for a few different bootable diagnostic tools as well as one for transferring drivers and software from a trusted computer to other computers.

Pro:I was able to make this 64GB stick bootable using ventoy 1.0.36, at least to boot Linux images. No problem, it just worked.The switch makes it write protected, as advertised. That's what I needed.It stores more and is faster than my ancient thumb drives with a write protect switch.Con:Raw capacity is 58GB. A 1TB Crucial SSD I set up advertised 1000GB and that's what it had. This thing is short, but most USB flash drives are.The USB3 speed is pretty sad. Yes it is faster than USB 2.0. But that is mostly just the cache, especially when writing. The flash is really slow and if you are writing a lot (like a 2GB ISO image, or 10...) then you soon fill up the cache and you might as well go have dinner because you will not want to wait for it. Boot speed is far faster than a CD, so there's that.It is quite expensive for a not fast, 64GB drive that holds 58GB.Conclusion:Ask yourself, how much of a premium do you want to pay for a write protect switch? You can get faster and cheaper flash drives. I like AData. But those do not have a write protect switch. That switch is literally the only reason I would consider buying this drive. And for that, I bought two.

Speed and reliability have been two plusses for me with this drive. But one unexpected bonus is that, with the cap on, it survived a trip in the washing machine. Not exactly the way one should treat a flash drive, but I was happy to see it was still usable after that misadventure!

Product went dead in less than a month of use

Works as expected, with solid performance. The manufacturer claims read/write speeds of R90/W30, but in my testing, I achieved R135/W41, which is excellent. The read-only mode also functions as intended. We’ll see how it holds up in the long run, but so far, so good.Here is some info:Protocol Version: USB 3.20Current Speed: High SpeedMax Current: 496mAUSB Device ID: VID = 0DD8 PID = 2004Device Vendor: NetacDevice Name: OnlyDiskDevice Revision: 0110Manufacturer: NetacProduct Model: OnlyDisk

Seems to be R/O, time will tell. Does not work with Raspberry PI 3B+ (-1 star).Low (<20MB/s) transfer speed (-1 star). I evaluate build quality based on how the drive holds up over time.3/5 - Will revise later.

I normally don't write a review but because there are so many reviews about slow speed, I just wanted to share my case. It was indeed USB 3.0 speed. Crystal Disk Mark shows >150MB/s sequential write but I doubt it. My real-world file copy in Windows Explorer between SSD and this USB stick showed 190MB/s read and 90MB/s write in a sequential very large file copy. For this price and the unique "write-protect" switch, this product has a good value. The red access LED is very easy to see but not too bright for eyes, which is also good. The physical quality looks chap though.
