So, what is the difference between EXT4 and Btrfs? You might wonder what the differences between the two file systems are? Before we proceed, we should highlight the fact that not all OS (Operating System) can deal with all types of files system.
Therefore, on Windows, you have a few file options (FAT32, NTFS, etc.) for storing data on your hard drive. On the other hand, Linus users have multiple files types to choose from. Btrfs and EXT4 are two common types in this regard.
Now, we are about to find out how both of these file types are different. So, stick with us.
Btrfs is commonly known as a B-Tree file system. It is one advanced and features pack file type. Therefore, even since its inception, it has been the talk of the town. The industry calls it an advanced file type because it works on the Copy on Write (CoW) mechanism.
This particular mechanism can store back the data after the modification. Therefore, the chances of data corruption aren't that high. Though this file system was introduced in 2007, many businesses still use it.
It is because it gives that room to developers to add new functionalities within the same file type. So, this is another reason why Btrfs is so popular.
As mentioned, the Btrfs file system gave plenty of room to developers for some updates. So, it lets them create various snapshots with ease. Note that these snapshots are not just readable but also writable.
In the Btrfs file type, the complete data is a copy on write (CoW). So, it doesn't change the data on the disk. Instead, it creates a copy. Therefore, this file type ensures no data corruption while handling huge file sizes.
As SSD's (Solid State Drives) are meant for high-speed data transfers. So, Btrfs is well optimized to work with solid-state drives. Therefore, it ensures that you get the best performance from your SSD.

Ext4 is the fourth version of Linux's extended file system (Ext). Initially, it was just an extended file system (ext) that was mainly used. However, the Ext file system is the latest offering by the OS manufacturer. So, even today, standards come with the Linux system.
Today, Ext4 is known as a journal-based file system. This is because this file system keeps a journal of the data which is saved on the disk.
Ext4 has been there for so long that it is considered one stable file type for Linux OS. So whether you have just shifted to Linux or want one reliable file type for storing your data, Ext4 would serve you fine.
As discussed, Ext4 is the updated version of their previous file types, including Ext1, Ext2, and Ext3. The good news for Linux lovers is that Ext4 is backward compatible with all its previous versions.
To some users, the journal-based data saving mechanism of Ext4 file type may seem a bit old school. But, in reality, it delivers consistent speeds, which matters the most to many users. So, it is one reason why many Linux users still use ext4.

Enough of EXT4 vs Btrfs. Let us find out some of the main differences between these two file types.
Btrfs Or B-Tree File System | Ext4 (Extended File System) |
The Btrfs file type supports partition size up to 16 EIB (Exibyte). | The Ext4 file type supports partition size up to 1 EiB (Exibyte). |
You can create up to 264 files in a Btrfs system. | Ext4 lets you create a max of 232 files. |
It is an updated and also reliable file system | It is one but a reliable file system. |
EXT4 vs Btrf are two main file systems for NAS hard disk. On Synology NAS or NAS devices of other brands, how to choose the right file system? If you are not sure which file system to choose for on Synology NAS Device, do not worry. We have created this brief guide to help you choose the best file system out of the two.
As we already discussed, Btrfs is one excellent file system. It has some good little add-ons. Further, it retains the old reliability aspect of its predecessor's file system while bringing in some new features. It even allows creating snapshots of snapshots, which is a very good feature.
Its copy-on-write mechanism is a welcome addition. So, in short, Btrfs is the more advanced and feature-packed file system for Linux users. You should go with the Btrfs file system if you want:
Ext4 is a more kind of standard file system with some new features. Basically, it is version 4 of the standard file system of Linux OS. However, it does offer some improvements. For instance, it has a journal-based storage system, unlike the copy-on-write mechanism of Btrfs.
However, its maximum file size capacity is not that much compared to Btrfs. So, it does have some limitations. You should choose the Ext4 file system if you want:
Though NAS is a reliable device, data loss still can happen. So, you never know when such stuff happens. NAS drives can lose data because of the following reasons:
