| Creates virtual block devices called /dev/zramX (X = 0, 1, ...). | |
| Pages written to these disks are compressed and stored in memory | |
| itself. These disks allow very fast I/O and compression provides | |
| good amounts of memory savings. | |
| It has several use cases, for example: /tmp storage, use as swap | |
| disks and maybe many more. | |
