Kingston DataTraveler Kyson USB Flash Drive - 128GB

There is about 1GB to 1.5GB that writes at 90MB/s, the rest only writes at 4-6MB/s. The read speeds are above 200MB/s as advertised. There is about 1GB to 1.5GB that writes at 90MB/s, the rest only writes at 4-6MB/s. The read speeds are above 200MB/s as advertised.

The only reason I bought this was because it claimed the fastest write speed advertised of any standard USB-A flash drive: 60MBps write speed.
Real world speed turned out to be 20 - 30 MBps while copying a single 3GB file.
An everyday flash drive such as the DataTraveler G4 achieves 16 - 26 MBps
So this is only 15 - 25% better. The only reason I bought this was because it claimed the fastest write speed advertised of any standard USB-A flash drive: 60MBps write speed.

Speeds are consistently around 115MB/s for the first 1GB and then it drops to a very jerky 30MB/s for the rest of the file.
Note that this is preformatted as FAT32, so there is 4GB file limit. You'll need to reformat this to NTFS or exFAT before you start transferring files if you might find a bunch of them not transferring over.

Build quality is pretty nice being all metal apart from the plastic keyring loop. Would have been nice if that was metal too though as that part of it feels exceptionally flimsy.

I am not an expert in USB drives, but found this drive to be sufficiently fast and a good price considering the spec level. Another reviewer commented that it wasn't as fast as advertised but I'm not too sure about that. It came in FAT32 format which was useful for me because of what I was using it for. Perhaps people looking to store over 4gb files should be aware they may have to do some simple formatting before using this drive. I'm no expert so I could be wrong about that. Overall, would recommend. I am not an expert in USB drives, but found this drive to be sufficiently fast and a good price considering the spec level.

The default partition for the 64 GB is only 32 GB, meaning when I nearly filled it, I realised I had to reformat and repartition it completely. Considering the nature of its content, I was worried about my work being corrupted by doing so. It should be set up correctly by default. Apart from that, it has otherwise been a good drive and most importantly, durable. Most of my other USBs are plastic and end up breaking in my bag or keychain The default partition for the 64 GB is only 32 GB, meaning when I nearly filled it, I realised I had to reformat and repartition it completely.

This drive is tiny, perfect to go unnoticed on your keys. This drive is tiny, perfect to go unnoticed on your keys.

Got it on sale at a great price. I Use it in the car to play music which it does well. The write speed isn't super fast, it takes a while to copy files to but I don't have a problem with that Got it on sale at a great price. I Use it in the car to play music which it does well.

I have been using Kingston flash drives since the early 2000s, and they are fast, sturdy, and reliable.

Nothing different from this one: fast, sturdy, and reliable. You cannot go wrong.

Also, remember that flash drives are transport media, not storage media.
So, do not use flash drives to store files or make backups. ;-) I have been using Kingston flash drives since the early 2000s, and they are fast, sturdy, and reliable.

Fast, large, portable—and cheap.
That was for the first couple months.

Drive is 8GB full and I get bad write on CrystalDiskMark. Recommened the 128gb or higher versions, or the Kingston DataTraveler SE9 G3. Fast, large, portable—and cheap.

Works as advertised. Works as advertised.

I brought a few of these for work with a focus on the adverted write speed being 60 MB per second. Lucky to Average 20 MB per second. I checked all hardware and simply put this is a budget drive with a premium look and none of the premium advertised features.
