The Best Filesystem for an external hard disk of 1TB with cross platform support.

Feb 012012

Disks are becoming cheaper and so it’s becoming common to have on our desk an external (usually USB) hard drive with a size of 1TB or more.
Now, once that we bring at home our new gadget the first question for us is: “which Filesystem should i use with this big disk ?”

There are a lot of options and the main point is once again a simple question: do you want to use this disk with several different operating systems ?
Perhaps you have a computer with a dual-boot with a Windows operating system , or perhaps you plan to use that external hard drive also with your Macbook…or connect it to a TV.

Free reserved space in ext3/ext4 Filesystems

The partitions that contains the ext3 and ext4 filesystems reserve the 5% of the total size of the filesystm by default. The idea here is even when you run out of disk space, the root user should still be able to log in and system services should still run. Without this option, the root user could be not able to acces and “clean up” since the system may become unstable, trying to log to in a filesytem full at 100%, for example. The other reason is to help the general optimization with less fragmentation of the filesystem.
