This drive is borderline fraudulent. The capacity is correct but the speed and reliability are not.

This drive transfers at USB 2.0 speeds despite it having 3.0 speed ratings all over the packaging and advertising. It also is very finicky to be recognized. There are times I have to plug / remove / re-plug the drive in multiple times before it is recognized. This same behavior has been shown on multiple systems. Very frustrating.

Avoid this at all costs. Even when it goes on sale.

I've purchased 2 of these flash drives as they offer amazing value.

Both have failed and corrupted. When they did work they get a MAX 3MB/Sec transfer speeds. When Kingston is questioned as the packaging says USB 3.2 GEN 1, they replied with "we we never actually advertise a speed as user environment and usage have an impact" For reference the average drive (HDD/SDD) is between 300MB/Sec to 7000+MB/Sec

I can no longer trust Kingston for my important data. All my SDD and flash drives are Samsung and HDD are Seagate Barracuda. Both offer a premium experience at a not-so premium price (sometimes).

High capacity for price.

So extremely slow its unusable. Maxes out at 7 mb/s and drops to 800 kb/s every so often. Single file transfer of a 2g file was going to take over 5 minutes.

This was the 2nd drive I purchased after returning the first thinking I got a lemon. NO, THIS IS JUST A HORRIBLEY SLOW DRIVE. Doing some more research this drive is USB 3.2 gen 1 "compatible" drive, but does not achieve the speeds of 3.0. No where does Kingston or memory express provide read and write transfer rates as to intentionally hide this fact from the customer. My assumption was it would be par to other USB 3.0 devices achieving at least 100mb/s or better. I will be returning this drive also. This should be better advertised and clear description of speed with out tricking the customer into thinking its a better drive than it is.

Speed

I haven't had them fail yet, but they are horribly slow. There is about 4GB of high speed caching, then write speeds drop to a little over 10MB/S. They are great for keeping small files at hand and moving them around, but if you plan on moving large files around with them don't waste your money.

Quick write speed

Reliability

I bought two of these. The first one started getting read and write errors after about 3 weeks. Thankfully ME was able to refund it for me even though my store return window had just passed. The second one failed about 9 months after that with the exact same symptoms, and is no longer readable as a drive. The usage for both drives was very light as far as the writing, and moderate as far as the reading. I'm going to buy some smaller capacity ones and get the warranty on them.

I left this USB stick plugged in for a week, so I guess it can't handle that.

no longer recognizes 128GB. will only write to 38GB
