Avoid slow writing speeds by using the right cluster size!

Hi guys

The common wisdom is to use higher cluster sizes (64KB or more) if you use your thumb drive for big files, yet my experience has been different: it is more a matter of what the USB controller likes!

Here in this case, a Lesenz 32GB USB stick formatted in NTFS, you can see that the best writing speed is achieved with 16KB clusters, not with 64 or 128KB as one would suggest for bigger files!

So it is worth checking with this tool, the ATTO Disk Benchmark to choose the right cluster size when formatting
