Ok Remi, its not AS much data, but its lots for 16 seconds of data transfer.
I have good motherboards, ones that I bought specifically for fast data transfer, one of them even is supposed to do something that eliminates one area that it has to pass thru from drive to drive. I believe it doesn't have to go thru the northbridge or something like that. Sorry its been a while since I built that one.
I have good quality high speed SATA drives, the correct cabling, correctly setup. When I changed over to this setup, yes, installing XP Pro was quite a bit quicker, as was just transferring large files, but still, a fresh OS install takes probably 15min without updates etc.
If I could get it down to 5 min, that would be a huge increase. If I could get it down to 1min that would be a miracle. But 16 seconds? Holy crap.
