Here I'll benchmark the seek times of various thumbdrives. Seeks times are useful when you're syncing Bitcoin/Altcoin wallets.
I'm using the seeker tool for the purpose. All units in ms.
HP -- 0.53
Kingston -- 2.2
Sandisk cruiser blade -- 0.88
Sandisk cruser micro -- 0.73
Amkette robusto 0.93
Strontium Bold -- 0.64
Strontium TNT -- 1.06
Transcend Jet USB 3.0 -- 0.7ms (on USB 2.0)
As expected, Kingston is the most popular and worst brand which's expected cause it's the people's top choice, similar to Windows.

This bash script will generate CSV output for any altcoin/Bitcoin given the path of it's daemon binary. It makes RPC calls via the binary to a running altcoin/Bitcoin server to generate a CSV value to stdout. You can plot it later on in Libreoffice Calc.

Copy-paste this in a text file and give it a .sh extension. Read the comment to learn how to use it.
