DATOptic has answer the challenge of storage industry with the world most cost-effective, high reliable and high performance, massive storage 60.0TB (20x 3.0TB HDD) in 4U rack mount 20 bay and 4x SATA hardware raid engines. Which can be as a turn-key system ready to deploy where hot plug capable, protected data, fast and easy to manage is a must.

Available in twenty hot swap bays with 4U rack mount chassis with quite fan and quad hardware raid engines. Each RAID engine controls five HDD raid array interdependently, which allows flexible raid configurability:
- RAID0/1/3/5/BIG - FOUR independent raid which can be use for sperate volumes or combine as RAID0, SPAN, 30.31, 50, 51 and transfer rate up to 600MB/sec
- JBOD - Ten (20) individual HDD can be access simultaneously fully support hot swap (drive remove without shut-down)

High performance
RM20_HR50 provides an unparalleled of high reliable of protect data for users, who demands Enterprise class performance with a fraction of cost. With twenty (20) SATA II/SATAIII 7200 rpm hardware in our RM20_HR50, it easily delivery up to 600MB/sec in read and over 600MB/sec in write

Here is the test environment: MACPro 2006, 1x eSATA_PCIe8, OS 10.6.3
- 1x RM20-HR5 with 10x Hitachi Deskstar 2.0TB Model HDS722020ALA330
- Configured as RAID50
- Connect to MAC Pro via mini-SAS cables

Email Notification
With a simple set up, our RM20-HR50 can perform an email notification with select-able from information to a critical events, this allows administrator foresee error read/error write base on S.M.A.R.T feature of each individual HDD...

Embedded Raid Advance Features
Embedded into its hardware raid controller, the suspend mode and raid rebuilt priority setting functions, these allow end user customize the configurations per their desire

Suspend : Set the RAID array go to sleep mode within specific idling timing, from 1to 10922 min (half year 182 days). Suspend mode will save electricity, make our RM20-HR50 more environment friendly, and of course prolong the life of hard drive.

Raid rebuilt priority setting:
Allow raid engine allocate more I/O CPU for rebuilt a degrading raid or concentrate of I/O operating, this will affect the transfer rate when rebuilt is needed
