Internal USB Drive
An embedded USB (eUSB) device is used as the internal flash (disk0). See
the size shipped with each model.
External USB Drives (Optional)
The ASA 5500-X supports external USB flash drives for data storage. The ASA 5500-X uses disk1 as the external
USB flash drive identifier. When the ASA is powered on, an inserted USB flash drive is mounted to disk1 and
available for you to use. Additionally, the file system commands that are available to disk 0 are also available to
disk1, including copy, format, delete, mkdir, pwd, cd, and so on. When you remove the USB flash drive, the
system unmounts disk1, and disk1 becomes an invalid file system label that you can no longer access.
If you insert a USB drive with more than one partition, only the first partition is mounted.
USB Online Insertion and Removal
While the ASA back panel has two USB slots, only one is supported for online insertion and removal (OIR), with
priority given to the USB drive that was inserted first. For example, based on the time sequence, the first inserted
USB flash drive is mounted to disk1, regardless of the slot in which you insert it. When you insert a second USB
device, an error message appears on the console to notify you that an extra, unsupported USB flash drive exists.
Removing either one of the USB devices does not change the priority that you just established. To change the
priority you must safely remove the USB device and begin again to establish the desired priority.
FAT-32 File System
The ASA 5500-X supports only FAT-32-formatted file systems for the eUSB and external USB drives. If you insert
an external USB drive that is not in FAT-32 format, the system mounting process fails, and you receive an error
message. You can enter the format disk1: command to format the partition to FAT 32 and mount the partition to
disk1 again; however, data might be lost.

Solid State Drives

You must install a Cisco Solid State Drive (SSD) for use with the some software modules. Only Cisco SSDs are
supported. You can install one SSD in the ASA 5512-X, ASA 5515-X, and ASA 5525-X. You can install two SSDs
in a RAID 1 configuration in the ASA 5545-X and ASA 5555-X.
Note: When you install an SSD for the first time, you must reload the ASA and then re-image the installed module.
The SSD is hot-swappable. The SSD resides in a carrier, which you install into the drive bay. You can use the SSD
with an AC or DC power supply. See
more information.
