# Storage overview

The Qualcomm^®^ Linux^®^ storage guide describes the features and supported device types, enabling you to configure, customize, and deploy storage capabilities optimally and efficiently.

The following table lists the supported storage types.

| Storage type | Version | Supported SoC |
| --- | --- | --- |
| Universal flash storage (UFS) | <ul class="simple"><br><li><p>v2.1</p></li><br><li><p>v2.2</p></li><br><li><p>v3.1</p></li><br></ul> | <ul class="simple"><br><li><p>All</p></li><br></ul> |
| Embedded multi-media card (eMMC) | <ul class="simple"><br><li><p>v5.1</p></li><br></ul> | <ul class="simple"><br><li><p>QCS5430</p></li><br><li><p>QCS6490</p></li><br><li><p>Qualcomm Dragonwing™ IQ-615</p></li><br><li><p>Qualcomm Dragonwing™ IQ-8275</p></li><br><li><p>Qualcomm Dragonwing™ IQ-9075</p></li><br></ul> |
| Non-volatile memory express (NVMe) | <ul class="simple"><br><li><p>v1.3</p></li><br></ul> | <ul class="simple"><br><li><p>Dragonwing IQ-8275</p></li><br><li><p>Dragonwing IQ-9075</p></li><br></ul> |

## Storage use cases

- Boot from the primary storage device: Store the required images to boot up the device by reading the images such as XBL, AOP, Qualcomm Trusted Execution Environment (TEE), and kernel, from storage.
- Save user-specific data: Store customized information such as videos, photos, and documents.
- Support read-only logical unit number (LUN)/region: Store images such as TEE and CDT. LUN is an independent processing unit on a UFS device.
- Stores data in an authenticated, access-controlled, replay-protected manner in RPMB LUN/partition: Replay protected memory block (RPMB) is a well-known LUN (WLUN) in UFS device and a special partition in eMMC.

Note

- See [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70030-115/soc.html) that are supported on Qualcomm Linux.
- Configure the device to boot from only one storage source. Use the second source only to store files. If both have bootable files, the system might crash or behave unpredictably.
- Detailed information on the storage hardware architecture is available to licensed developers with authorized access. For more information, see [Qualcomm Linux Storage Guide - Addendum](https://docs.qualcomm.com/bundle/resource/topics/80-70030-6A/overview-addendum.html).
