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.
