Hi guys,

I am writing, because I want to have Kali LivePersistent USB, and I really don't know how fast my Pendrive should be.

Some ppl say that 80MB/s writing speed is enough, but I have a pretty cool offer for 170 MB/s one.
The problem is -> My HDD speed is 100MB/s (don't have the SDD one). Will my Pendrive 170MB/s be downgraded to 100 MB/s when launched Kali or 100 MB/s will be only for HDD-Pendrive communication and doing other things (like "count from 1 to 1,000,000,000,000 and write it into Pendrive) will be taken directly from RAM and then the writing speed will be 170 MB/s ?


I really need help ;(
