After unpacking we connected the USB flash drive to a USB3.0 port. You will get around 232GB of useable empty free space

Using the USB Drive Info we can get more details about the drive

Passing to the performance, we used the CrystalDiskMark and ATTO Benchmark software, which reported around 231MB/sec reading and up to 31MB/sec writing, which proved to be much higher than what KIOXIA advertises the product about.

Concluding this, the KIOXIA TransΜemory U365 256GB USB Flash drive proved to be a good solution for road warriors who wish to transfer big files at the palm of their hand. The reading performance proved to be much higher than what KIOXIA mentions about (221MB/sec vs 150MB/sec), while the writing performance with big files is around 30MB/sec and if you need to write small files better avoid this product since the small writing performance is low. The USB flash drive is armed with KIOXIA's 5years of limited warranty and if you can find available around 28~30 Euro you should consider buying it.
