The same device will offer differing levels of available storage depending on the chosen RAID level. If RAID 0 is used, the system combines the capacity of all SSDs in order to enhance data-transfer speeds. The available storage will equal the combined physical capacity of all the SSDs on the device. However, if the device is configured with RAID 1, two copies of the data are saved simultaneously in order to protect your data if one SSD fails. As a result, the available storage capacity will be half of the combined physical storage capacity, as half the storage is used for backup copies. For example, a device with two 1 TB SSDs in a RAID 0 configuration will have 2 TB of available storage capacity, but with RAID 1 the available storage capacity will be 1 TB.
Note that the supplied accessory box is manufactured from recyclable paperboard. The condition of this material will naturally deteriorate over time and is not covered by an ASUS warranty. Check your accessory box regularly and, when it is no longer suitable to be used as a laptop stand, please dispose of it responsibly.
ASUS Control Center is optional and its availability varies according to country. Please check with your local ASUS retailer for details.
Please note that the keyboard design varies by model. Only ExpertBook B9 models with Intel^® vPro include shortcut keys to enable the AI noise-canceling technology and mute the microphones.

RAID technology

RAID, or Redundant Array of Independent Disks, is a storage technology that allows multiple drives to behave as one. ExpertBook B9 supports both RAID 0 and RAID 1 levels¹⁹ for superior performance for improved data security. The former stripes data stored evenly across two drives for up to 2x faster operations.⁷ The latter, by contract, automatically creates an exact copy of all data on both disks — so if one should fail, it’s quick and easy to recover from the other.
