Hello, is a WD Green HD with 5400RPM too slow for backup loader? Is there a noticeable different in the load speed between a 5400rpm and 7200rpm HD for wii backup loader?

It doesn't make a noticeable difference with external HDDs over USB 2.0, that's where the biggest bottleneck is.

edit for clarity: Data transfer in any system is only as fast as its slowest component. Most 5400RPM HDDs can give a transfer rate of over 1000Mb/s, but USB 2.0 has a maximum transfer rate of 480Mb/s. It doesn't matter that a 7200RPM HDD is even faster than a 5400RPM, the fact that it's going through USB means that the most you'll ever get is 480Mb/s regardless of the HDD.

I use a usb-powered 5400rpm drive. I think it's fast enough, though my guess it can be faster if you have a better harddrive. it would be nice to try a SSD

Just copy a big file from the external HDD to an internal one on your pc and stop the time. Then compare your result with the ~8MB/s which is the theoretical maximum you can get with retail discs, and be happy.

That make prefect sense. The WD Green is fast enough for Wii loader plus 5400rpm hdd will save me some money on my energy bill too. Thanks

    i used to go out to the recycling center every couple weeks and look at the crts and other electronics people would drop off. Usually screens were broken or severely scratched from being tossed around. Did find a good one here and there, but never anything like a 1080i widescreen crt.

    Is it piracy if it was released for free? Not in my opinion, but I also think it's not piracy if buying it isn't owning it, and it's not piracy if you can't buy it from the original creators anymore.

    Free release can have loopholes where they still make money through ads
