Kingston DataTraveler SE9 G3 USB Flash Drive - 256GB

I bought two of the 64GB version, mainly for the performance.
I expected lower in performance in the smaller capacity version, just not this bad for writes.
The write speed was particularly bad, if I knew they were this bad I would not have purchased them.

Over the whole drive the write speed averaged 14.014MB/s and read 97.671MB/s.
The max write was 20MB/s and read was 210MB/s I bought two of the 64GB version, mainly for the performance.

While far cheaper products are available, I chose this DataTraveler SE9 G3 model for faster writing speed. However, quite disappointed to see it was only 46mb/s which is less than half of the advertised speed. Reading speed sure is 210Mb/s but not what I needed.

Very nice design, almost shines in the sun. It hasn't failed me yet after a couple months of owning it. Not much to say, great value for money. I do not have any cons for this product.

The USB drive achieves the read/write performance advertised over long file transfers (>5GB). For the first GB written in a batch, the write speed appears to be >3x faster than advertised until the USB drive warms up and stabilises around the specified write speed.

The drive does come formatted as FAT32 (likely for compatibility) which limits the maximum file size to 4GB. Reformatting the drive to basically any other modern file format will fix that problem. (It appears that ExFAT is the most compatible of the file formats that allow >4GB files)

You're almost certainly paying for the extra performance, but if you know you need it then this USB drive certainly offers it.

Edit: Another test suggests that it doesn't reliably hit the advertised write speed when the drive is warm

I bought 3 of these flash drives. Two worked and one failed right from the start. It couldn't be repaired or reformatted. Now I'm wondering how long the other two will last.

I used this USB drive to install Windows on my upgraded NVMe SSD, and it worked perfectly. Quick formatting, smooth booting, and no issues during setup. It did exactly what I needed—fast, reliable, and ready to go. I used this USB drive to install Windows on my upgraded NVMe SSD, and it worked perfectly.

It runs hot, I do not like these drives getting over 50 degrees Celsius. I have to put a fan on top to draw air through for cooling when copying more than about 300GB. Otherwise it copies large files at 100 - 150 MB/s. It runs hot, I do not like these drives getting over 50 degrees Celsius.

Do not buy! Often only achieves write speed of 1Mbyte/s, otherwise not much more. Simply formatting it gets 1/4 finished after 2 hours. That's a lot less than the 100Mbyte/s write speed specified. It's totally unusable. Do not buy! Often only achieves write speed of 1Mbyte/s, otherwise not much more. Simply formatting it gets 1/4 finished after 2 hours.

Like a lot of people have been saying, the write speed is not even a little close to advertised. I spent 15 plus hours transferring 258gbs of files, and it didn't even transfer properly the first time. Reformatted and tried again. Another 15 hours. Read speed seemed a bit slow. Tired in device I was making the USB drive for, ended up disappearing part way through reading it and needed to restart the device. Sent back for store credit. Got a micro sd Adata to replace it with and a card reader, which ended up cheaper. Transfer only took 4 hours.

The Kingston DataTraveler 128GB USB 3.2 Flash Drive is a great little device with a slim design that's perfect for laptops with closely spaced ports. It allows me to connect it effortlessly without blocking other ports. It's light and has a hole/loop on the end so you can attach it to a keychain or lanyard. I can't really comment on the copying speed as I haven't tested it. I'm very happy with its performance and capacity—it easily stores a large number of photos and videos.

A perfect example of you get what you pay for. Excellent for DJs looking for a fair value products that gets the job done and looks cool on a lanyard A perfect example of you get what you pay for. Excellent for DJs looking for a fair value products that gets the job done and looks cool on a lanyard
