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.

Crafted to perfection
The magnesium-lithium alloy used in ExpertBook B9 is durable yet lightweight, resulting in a laptop that’s 16% lighter than the previous model3. The chassis is methodically-crafted, undergoing a complex 21-stage process to create its tough, but exquisite, exterior.
CNC-milled for strength
To create the precision-cut lid and complex keyboard surround of ExpertBook B9, a high-precision CNC-milling process is used to shape single pieces of solid metal. This reduces unnecessary internal voids, rendering the entire chassis tougher and stronger than is possible using traditional metal-stamping methods.
First impressions count
The ASUS design team incorporated architectural elements into the design of ExpertBook B9, with precisely shaped corners and edges giving it a clean, elegant look. Star Black finish is unique too, taking inspiration from the universe and stars in the night sky to create a color that exudes both mystery and wisdom. The finish is iridescent, with tinges of red and green appearing depending on how light strikes the surface, while small shining particles embedded in the finish resemble stars. This stylish design goes against the reputation of typical business laptops being plain and boring.
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.
Speed is of the essence
A high-performance PCIe 3.0 x4 SSD gives ExpertBook B9 the fastest-available consumer storage so you’ll never be kept waiting for the operating system to launch or for applications to load. And because they don’t have any moving parts, SSDs are also incredibly reliable and quiet.
faster than PCIe x24
faster than SATA 3 SSD4
Mobility without bounds
ExpertBook B9 incorporates ASUS WiFi Master technology, so you’ll enjoy faster and more reliable WiFi connections at greater distances than ever before. Combined with the latest Bluetooth® 5.0 that lets you connect your favorite devices with less impact on battery life, ExpertBook B9 gives you the freedom to do whatever you need, wherever you want to!
WiFi 6 up to 3x faster than WiFi 58
Smooth FHD video streaming at distances of up to 300 meters or more9 with WiFi Master
Up to 65-meter range, with improved stability when USB 3.1 Gen 1 interference is present9
Panel Self Refresh technology
Panel Self Refresh technology relies on dedicated memory built into the LCD display panel itself. It’s used when the display is showing a static image, and saves energy by shutting down the video processor and its circuitry. This lower power consumption allows a much longer battery life.
To safeguard personal privacy and business information against malicious hackers, ExpertBook B9 has an integrated privacy shield that simply slides over the webcam for instant privacy.
AI noise-canceling technology in the MyASUS app
The AI Noise-Canceling Mic feature in the MyASUS app effectively filters out unwanted ambient noise There are two modes: Single-presenter mode allows the voice directly in front of the PC to be heard clearly; while Multi-presenter mode clarifies speech from different direction, ensuring optimum quality for group conference calls. The AI Noise-Canceling Speaker feature filters out all ambient noise apart from human speech — so you’ll hear what everyone else is saying.
Control conferencing with a simple click
ExpertBook B9 also features shortcut keys to quickly enable the AI noise-canceling technology or mute the microphones, ensuring that conferencing is slick and safe.22
