![]() ![]() On the flip side, the bigger the cluster, the less clusters your hard drive needs to search, so larger clusters technically mean faster file-reading and better performance, particularly with big Blu-Ray quality movies. A 2MB file in a 2MB cluster is much less wasteful than a 2MB file in a 32MB cluster where you effectively waste 30MB of hard drive space.) If you’re dealing with small files, then a 2000 to 4000kb cluster size is better because if the files are smaller than those sizes, less space is wasted per cluster. Allocation units are the same thing as clusters, and each file on your hard drive takes up a certain number of these clusters depending on the file size. What is allocation unit size, or AUS, I hear you asking. Here you’ll be presented with a number of options, but the ones we’re focusing on are “File System,” which you want to change to exFAT, and “Allocation unit size.” Plug your external hard drive into your PC, go to “This PC,” then right-click it under “Devices and drives” and click “Format.” So let’s format that hard drive to something more universal. ![]() This builds on the old FAT32 format, and its key advantage is that it doesn’t have the restrictive 3GB file size limits of its predecessor (which is crucial if you have a collection of HD-quality/Blu-Ray movies). My recommendation is to format your external HDD into the exFAT format. NTFS is great when you’re using it exclusively with your PC as it has a number of handy security features, no file size limits and so on. In most cases these devices are not compatible with the NTFS file format. If you’re preparing a dedicated movie hard drive, then you’ll probably want to hook it up to your TV, DVD/Blu-Ray player or games console. Here’s everything you need to know to prepare the perfect external hard disk for storing movies. Sure, but there are quite a few variables to consider, such as what the best hard drive format is for compatibility with the greatest number of devices, allocation unit sizes, and what the best video format is to strike a perfect balance between compatibility and video quality. ![]()
