NAS HDD Testing

Gents!

 

After watching the nasferatu video you guys put out, I noticed that Wendell said he put the drives through a stress test and I was just wondering, how is this done? For example, I have 5 3tb seagate NAS drives and I want to test all of them at once in the intended raid zf2 array configuration, how is this done?

 

Thanks and keep up the great work!
