# 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/80-70033-115/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.
- Currently, UFS and eMMC coexistence is not supported. The platform supports either UFS or eMMC as the boot media. However, using the other storage device as secondary storage may not be supported due to the shared power rail architecture. This applies to QCS5430, QCS6490, Qualcomm Dragonwing™ IQ-615, Qualcomm Dragonwing™ IQ-8275, Qualcomm Dragonwing™ IQ-9075.
- 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/80-70033-6A/overview-addendum.html).
