Am I better off making an OS Partition and a Data partition on the Samsung and running off that soley? Or should I leave the Samsung for data and install the OS on the Maxtor. I'm looking for optimal HTPC performance.
Long term (in a year or so) I'm planning to put a SSD in for OS to cut boot time.
I agree on using the Samsung, but there is a benefit to partitioning.
You could create an OS partition and a data partition (and even a paging partition and various others if you want to get crazy). Having a separate OS partition would allow you to wipe it if it gets infected or you feel like rebuilding or whatever, without losing any of your other data.
