Thanks for the speedy response. Just curious, if you set the size (in your case 25G) on NAS/SAN you must take the time limit off? How did you end up deciding on 25G and not a range of sizes?
I have to admit that I haven't just tested a single hard drive so I have always done my tests based on size, when I have tried running fio on just a plain filesystem it still asks for a size, is there a flag I am possibly missing?
Again, many thanks and I am enjoying the website!
