| 11 | Open-Channel SSDs implement a set of extension to SSDs, that | |
| 12 | exposes direct access to the underlying non-volatile memory. | |

| 14 | If you say N, all options in this submenu will be skipped and disabled | |
| 15 | only do this if you know what you are doing. | |

| 31 | ---help--- | |
| 32 | Allows an open-channel SSD to be exposed as a block device to the | |
| 33 | host. The target is implemented using a linear mapping table and | |
| 34 | cost-based garbage collection. It is optimized for 4K IO sizes. | |

| 38 | ---help--- | |
| 39 | Allows an open-channel SSD to be exposed as a block device to the | |
| 40 | host. The target assumes the device exposes raw flash and must be | |
| 41 | explicitly managed by the host. | |
