I just installed an 80 GB HDD into this server. It's mounted to wp-uploads on boot, so whenever I upload a file to the server, it goes directly onto the 80 GB HDD. I think it's 7200 RPM but I don't know for sure. It's also not from the 90s (like the 10 GB HDD that contains the rest of the filesystem). Accessing files on it seems faster than from the 10 GB HDD. This also means that I have 80 GB more storage space than before, so I don't have to upload everything to Picasa and then embed it. I'm really excited, considering that I got the HDD for free.
