I'm currently looking to install Drivepool on my Windows 8.1 headless server. This is mainly used for media (TV, movies, music), photos (which are also replicated to Google Drive), user files (direct to server), as well as backups from one other windows machine. I currently have my media spread across two disks 1 x 2tb and 1 x 1.5tb. These are pretty much full. I've purchased 2 x 3tb drives to provide for some redundancy as well as future headroom. I have a few questions before I jump in and start. 1 - Is there any need to re-organise the data on the disks before pooling them. For example currently on one disk there are movies and the other TV shows. Is there any benefit to bringing these onto as single 3tb disk or should I just leave them as they are? 2 - One the drive are pooled and new files are added are they just scattered anywhere on the disks in the pool - so for example if you pulled out the disks (say because of a machine failure) and you put them into another machine would you then see (say movies) across any of the 4 drives under Windows Explorer. 3 - I use SabNzb, Sickbeard & Plex for all of my video downloads and management - when configuring when using Drivepool do I just use the Drive and Folder structure in Drivepool? Sorry if some of these questions are a bit basic - I'm just trying to get my head around the concept of pooling from a simple practical perspective.
