What is a block group in Ext?
2.1. ext4 allocates storage space in units of “blocks”. A block is a group of sectors between 1KiB and 64KiB, and the number of sectors must be an integral power of 2. Blocks are in turn grouped into larger units called block groups. Block size is specified at mkfs time and typically is 4KiB.
How many inodes are in ext4?
One of the important changes in EXT4 is that inodes are now 256 bytes, as opposed to 128 bytes as they were in the EXT2/EXT3 days. That means there are 16 inodes per 4K block in EXT4, so the 8192 inodes per block group should occupy 512 blocks at the beginning of each group.

What is SSD superblock?

Is XFS still used?
The Extended File System. The Extended File System is actually a family that currently includes ext2, ext3, and ext4. It was the de facto standard for many years and it is still commonly used.
What is the difference between Block and flex layout?

The inner display type is flex, so items directly inside our container will participate in flex layout. This is something you might never have really thought about but probably understand anyway.
What is the Flexbox layout module?
The Flexible Box Layout Module, makes it easier to design flexible responsive layout structure without using float or positioning. The flexbox properties are supported in all modern browsers. To start using the Flexbox model, you need to first define a flex container.
