ext4 что плохо с ссд работает?))
Disadvantages of using Ext4
Ext4 is built on older technology, so it lacks modern file-system features found in systems like E2FS and BtrFS.
Ext4 has journaling on by default, and new users likely won’t know how to disable it to save read/writes on their SSDs.
BtrFS (B-Tree File System)
when talking about solid state drives, Btrfs is a pretty solid file system for basic usage. Initially designed at Oracle Corporation for use in Linux, Btrfs is a new kind of file-system that was created to mitigate problems, improve system performance, and make repair simple.
One reason that many people consider BtrFS for an SSD is that it doesn’t use a file system journal. Not having journaling allows it to save on write space (which is limited on SSDs). Also, it has a more modern architecture, which makes it quite fast when accessing data. In addition, BtrFS also has a robust snapshot feature, which allows users to create (and roll-back) changes to the system instantly.
As you might expect, BtrFS supports the usual SSD features like TRIM, and other SSD optimizations (like defragmentation, etc.).
Advantages of using BtrFS
BtrFS doesn’t have journaling on by default, so unlike Ext4, you won’t need to turn it off if you don’t want file system journals eating into your read/write rate.
The file system is new and under development so new features are added regularly.
BtrFS has an SSD defragmentation feature that allows users to clean up the data on their drive.
Disadvantages of using BtrFS
BtrFS is highly unstable and has the potential to crash and corrupt your data if something goes wrong.
BtrFS has a copy-on-write feature that is arguably just as bad as filesystem journaling, and could (potentially) exhaust your SSD read/write limit.
