ARC-5020 4-Bay RAID 8TB

DESCRIPTION
Highlights
The ARC-5020 RAID box offers a truly innovative eSATA (3.0Gbps) / USB 2.0 solution for use with your PC and Mac workstation. Designed and leveraged with Areca existing high performance solution, this RAID box delivers high-capacity performance at the best of cost/performance value. With RAID box technology, it allows one HDD failure without impact on the existing data and failed drive rebuild is transparent to the host. The Mac Pro internal hard drive backplane mounting system is a very nice feature support up to four internal 3.5" SATA connector. Users simply add internal extension cable from those empty backplane to ARC-5020-3 re-driver board to have eSATA connector for ARC-5020.

Unparalleled Performance
ARC-5020 RAID box unleashes the power of 3.0Gbps performance and NCQ support on the eSATA host port. The eSATA port delivers in excess of 210MB/s sustained RAID 5 reads and over 176MB/s RAID 5 sequential writes. The result is superior overall performance compared to other 4 bay eSATA solution. High transfer rates make ARC-5020 RAID box well suited for audio/video application, especially the rapidly growing demand from the Mac Video Editing markets. With the target mode multiplier emulation, both eSATA and USB2.0 host channel (with port multiplier function) can support multiple volumes (up to 4).

Unsurpassed Data Availability
The ARC-5020 RAID box provides RAID levels 0, 1, 10, 3, 5, Single Disk or JBOD RAID configurations. Its high data availability and protection derives from the following capabilities:

• Online RAID Capacity Expansion
• Array Roaming
• Online RAID Level / Stripe Size Migration
• Global Online Spare
• Automatic Drive Failure Detection
• Automatic Failed Drive Rebuilding
• Disk Hot Swap
• Online Background Rebuilding
• Instant Availability/Background Initialization
• Auto Reassign Sector and Redundant Flash Image

Easy RAID Management
Manual configuration and monitoring can be done through the LCD Control Panel, RS-232 and LAN port. The LCD Hot-Key supports one-step easy RAID configuration to simplify the firstly setup of ARC-5020 RAID box. It’s API library supports customer to write its own monitor utility. The hardware monitor can monitor system voltage, temperature and fan. Enclosure management features include fault indicators and status LEDs, event notification and user configurable audio
alarms via eSATA in-band signal.
