There is a lot of information out there on this subject, but I would Start Here and try to explore if you want to take this further. 32-bit Linux systems limit both file and file system size to 16 tebibytes. 2 63-1 bytes), though this is subject to block limits imposed by the host operating system. XFS supports a maximum file system size of 8 exbibytes minus one (i.e. It was created to support extremely large filesystems. XFS is a highly scalable, high-performance file system which was originally designed at Silicon Graphics, Inc. This will slightly improve performance, because certain new features of ext4 can also be used with ext3 and ext2, such as the new block allocation algorithm. It is backward compatible with ext3 and ext2, making it possible to mount ext3 and ext2 as ext4. ext4 features several improvements over its predecessor, amongst which include support for files upto 16 tebibytes ( 1 tebibytes equals 1,024 gibibyes, with 1gibibyte equal to 1.074 gigabytes) and a maximum volume size of upto 1 Exbibyte. The answer depends on your precise requirements.Įxt4 has become the default filesystem for several of the popular Linux distributions including Ubuntu, Fedora and openSUSE. So it is an option, even given what I've said. Of course you may be 99.99999% certain you'll never touch Windows (lucky you if that's the case :-) ) but my point is just it's difficult to fully judge future requirements, and so for the sake of losing the few benefits you'd get from Ext4 on an external drive, you're probably best going with fat32 - if just for compatibility reasons.īut, as I mentioned above, it's worth noting you can access Ext3 drives on Windows (not sure about Ext4) - it's just a hassle to get access to them set up on Windows 7. Although it was possible by installing extfs on the Windows VM, the settings wouldn't save - so now whenever I need Windows, the first thing I have to do is hunt down the extfs installer, configure, then I can access the drive. Later, I had a requirement to install Windows 7 as a Virtual Machine and wanted to access files on the external drive. I was in a similar position to you a couple of years back. Each volume within an APFS container can have its own APFS format-APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).I would say no, simply because, for your own convenience, you may well want to use it on other machines in the future. You can easily add or delete volumes in APFS containers. For example, folders named “Homework” and “HOMEWORK” are two different folders. For example, folders named “Homework” and “HOMEWORK” are two different folders.ĪPFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. Choose this option if you don’t need an encrypted or case-sensitive format.ĪPFS (Encrypted): Uses the APFS format and encrypts the volume.ĪPFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. If you use your drive with both PCs and Macs, format. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.Ĭhoose one of the following APFS formats for Mac computers using macOS 10.13 or later.ĪPFS: Uses the APFS format. exFAT is a lightweight file system compatible with all versions of Windows and modern versions of macOS. If desired, you can specify reserve and quota sizes for each volume. When a single APFS container has multiple volumes, the container’s free space is shared and is automatically allocated to any of the individual volumes as needed. Newer Seagate and LaCie branded external drives come preformatted with the exFAT file system, which allows it to be used on both Mac and Windows without. macOS 10.13 or later supports APFS for both bootable and data volumes.ĪPFS allocates disk space within a container (partition) on demand. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals.
