The Switch's eMMC storage features a large user area, two smaller boot partitions and a replay-protected memory block which is unused (no authentication key is programmed).
All official partition names come from [[SystemInitializer]].

=== System Update Control ===
The 0x4000 bytes at offset 0xFC000 are used by [[NS_Services|NS]] and [[Boot|boot]] for keeping track of the status of a system update. This area is used by the [[NS_Services#ISystemUpdateControl|ISystemUpdateControl]] commands [[NS_Services#ApplyDownloadedUpdate|ApplyDownloadedUpdate]], [[NS_Services#ApplyCardUpdate|ApplyCardUpdate]] and [[NS_Services#ApplyReceivedUpdate|ApplyReceivedUpdate]].

| BootImagesSafe status. Set to 1 by [[NS_Services|NS]] during a system update and cleared by [[Boot|boot]] after restarting.
|}
 
=== Keyblob ===
Starting at offset 0x180000 is an array of 0x200-byte entries, for a total of 32 keyblobs. Each one is unique compared to the others and they are all console unique. This is officially known as the "EKS" (encryption key source) area.
 
From each 0x200-byte entry only the first 0xB0 bytes effectively form the keyblob as below.

| Keyblob encrypted payload
|-

|}
 
The active bootloader's version (offset 0x2330 in the BCT) acts as an index (<code>version-1</code>) to control which keyblob should be installed into the system.
[[NS_Services|NS]] uses this during system updates to install the keyblob into the [[BCT#customer_data|customer data]] section in BCTs (offset 0x450).
 
[[Boot]] also uses this index for repairing corrupt sectors.
 
The currently active keyblob is officially known as "SecureInfo".
 
=== NAND Patrol ===
The 0x200 bytes at offset 0x184000 are used by [[Filesystem_services|FS]] for keeping track of NAND patrolling.

The filenames for saveimages is just "<lower-case hex u64 saveID>". SYSTEM-partition saveIDs are specified by [[Filesystem_services|FS]] commands, while USER-partition saveIDs are determined by FS-module internally. The high u32 of the saveID is normally either 0x00000000 or 0x80000000.

The saves for all non-system applications, regardless of where the application is located(storageID), is stored here. Each user account which has savedata has a separate saveimage. Save-common for an application is presumably a separate saveimage too. Every saveimage here is ''only'' for applications.
