Freedom Technologies 
4820 provides 16TB SATA II enterprise redundant solution for
JBOD data storage applications such as clustering, streaming video and
heterogeneous storage, which require high throughput and continuous
uptime. The dual redundant RAID controllers remove a single point of
failure.
Included as standard, dual redundant, load-sharing power
supply modules and power management circuitry accommodate the dynamic
requirements of today's drives. Smart circuitry at each drive assures
data integrity by minimizing drive damage during insertion and removal.
This system further includes power supply-to-drive isolation, which
allows control over voltage and current fluctuations.

IOSmart allows for the flexible configuration of logical
drives, logical volumes and logical partitions and ensures instant RAID
availability via background logical drive initialization. Fibre loops'
load balancing is provided within the subsystem. The firmware's embedded
intelligent algorithms, such as Adaptive Write Policy and Guaranteed
Latency I/O, improve sequential write performance and ensure the fast
and continuous flow of data.
The DrvSmart utility provides an easy way to store data while keeping
it safe. One of the main DrvSmart functions, Media Scan, retrieves data
from degraded or damaged hard drives and handles low quality drives
in both the degraded mode and during the rebuild process. Other DrvSmart
features include disk cloning, drive roaming, SMART, transparent resetting
of non-responsive hard drives, and RAID parity update tracking and recovery.
