## Summary description

The EXSYS EX-3455 is a PCI Express x4 RAID controller that supports Serial ATA storage drives. It offers RAID levels 0 and 1, providing flexibility for data management and redundancy. Ideal for enhancing storage performance and reliability in server environments.

## Long description

The EXSYS EX-3455 PCI Express x4 RAID Controller is a hardware-based storage solution designed to enhance data management and reliability in desktop and server environments. This controller supports Serial ATA storage drives and offers RAID levels 0 and 1, allowing users to choose between performance optimization and data redundancy. The device integrates easily into existing setups, making it a practical choice for system upgrades without requiring complex software configurations.
Advantages
The hardware RAID controller provides seamless data management by supporting both RAID 0 for performance and RAID 1 for automatic data mirroring and redundancy. Installation is straightforward, connecting the motherboard and hard drives directly through the controller. When working with an existing operating system, data from the primary drive is copied automatically to the secondary drive in the background while normal system operations continue. During a fresh operating system installation, data is mirrored simultaneously to both drives without any loss in speed. Furthermore, the unit can be mounted flexibly in a 3.5 or 5.25-inch front bay or directly into a PCI Express slot, while the included LowProfile bracket allows installation in compact computer cases with a maximum height of 8 cm. Operating system independence is another notable benefit, as the device requires no external drivers or software to function.
Suitable for
Upgrading existing computer systems with hardware RAID functionality
Building new desktop or server setups requiring data redundancy
Enhancing storage performance using Serial ATA drives
Installation in standard towers as well as compact computer cases
Environments where operating system independent hardware solutions are preferred
When it may not be suitable
This controller may not be suitable for systems that require advanced RAID levels beyond 0 and 1, such as RAID 5 or 10. Additionally, users looking for software-managed monitoring utilities or specialized configuration interfaces will find that this hardware-only approach offers limited customisation.
Key specifications
Host interface: PCI Express x4
Supported drive type: Serial ATA
Supported RAID levels: RAID 0, RAID 1
Form factor compatibility: PCI Express slot, 3.5-inch front bay, 5.25-inch front bay
Bracket type: LowProfile bracket included for 8 cm height cases
Driver requirement: None
How to use
To use the EXSYS EX-3455, first power down the computer and disconnect the power cord. Insert the controller into an available PCI Express x4 slot on the motherboard, or mount the unit into a 3.5 or 5.25-inch front bay using the appropriate mounting options. If using a small form factor chassis, attach the included LowProfile bracket. Connect your Serial ATA hard drives to the controller and link the controller to the motherboard ports. Power on the system. For existing operating systems, the controller will automatically begin background copying data from the primary disk to the secondary disk. For new installations, proceed with setting up your operating system normally while the hardware handles simultaneous mirroring.
What to consider before purchase
Verify that your motherboard has an available PCI Express x4 slot or that you have an open 3.5 or 5.25-inch front bay available for mounting.
Confirm that your storage drives use the Serial ATA interface supported by this controller.
Determine whether your storage requirements are fully met by RAID levels 0 and 1.
Check the physical dimensions of your computer case if you intend to use the LowProfile bracket for compact enclosures.
Usage recommendations: Ensure all internal cable connections are securely fastened before powering on the system. Allow background synchronisation to complete naturally when integrating the controller into an existing operating system environment to maintain data integrity.
