High Performance RAID storage system using 2.5" Notebook Drives

With USB 3.0 !

Jared Platt in the UK with the CRU Tough Tech Duo

RAID - Not just a Four Letter Word
ToughTech Duo removes the frustration of RAID with an easy-to-use interface that provides RAID 0 and 1 functionality at the touch of a button. Configure Duo as a RAID 0 (stripe) for extra speed and storage capacity, or as a RAID 1 (mirror) for data protection from drive failure.

ToughTech Duo 3SR Features
ToughTech Duo 3SR boasts a passive thermal design for optimal heat dissipation, which requires no fans thus making Duo ultra quiet. Duo has front-accessible lockable trays, an intelligent LCD menu system, Kensington Lock, host connection LEDs, and a vertical stand. It connects to any host computer via USB 3.0 (2.0 compatible), and eSATA using an extremely fast Oxford 936 chipset. An AC power supply is also included.

To make sure you can connect in any situation, all cables and adapters are included.

ToughTech Duo 3SR is bootable in USB/eSATA mode on any computer that supports this feature.

Smart Firmware, Smart Software
Access SMART data (Self-Monitoring, Analysis and Reporting Technology) directly on the LCD menu to track drive temperatures and help prevent drive failure. Companion software (Win/Mac compatible) allows you to configure what temperature the warning LEDs turn on and/or the audible alarms sound.

Multiple Power Options in Multiple Countries
An AC power supply is included, along with plugs for US, European, UK, and Australian wall connections.

Swap Drives without a Screwdriver
Innovative trays used in ToughTech Duo allow you to swap a drive in a matter of seconds. Mount drives without screws for quick and safe access or screw down the drives in environments where additional protection is needed. This feature may be used to eject a drive to share with a colleague or replace both drives to access a 2nd RAID set. ToughTech Duo was designed for easy access - swapping drives will not void the warranty.

Creating a backup disk with RAID 1
How to rotate through backup disks:
Remember - a mirror, while it protects against hard drive failure, is only the beginning of your backup strategy. Keeping a separate copy of your data on another hard drive (in this case a third hard drive), helps protect you from data corruption and accidental file deletion. This is easily accomplished with a ToughTech Duo in mirror mode. Simply unmount the volume to stop all write activity, remove one of the two drives, and then insert a third drive. You can remount your ToughTech Duo immediately as you work. ToughTech Duo will rebuild your data to the third drive, restoring the full mirror. The removed drive can be treated as a backup that you can archive in a fireproof safe, off-site and away from the original data. You may access the information on your backup disk anytime with Duo or another enclosure or drive dock; it becomes a standalone drive.
