Disk Array 3SA
Addonics Disk Array 3SA system makes implementing sophisticated RAID technology into any computer as simple as counting 1,2,3. Designed to accommodate up to three 3.5" SATA, SATA II, SATA III, each hard drive can be easily secured inside or removed from the Disk Array rack with the simple aluminum drive drawer.

The Disk Array 3SA, in conjunction with different Addonics SATA RAID controllers, enables the hard drives inside the Disk Array to be set up in various configurations: as RAID 0, RAID 1, RAID 5 or JBOD, as individual hard drive, or whatever the mix that best fits the application. The Disk Array can start with as little as one hard drive and then expands as needed. Hard Drive can also be removed or added to the system without turning off your system power or restarting your computer (1).

The Disk Array 3SA can be mounted into any system with two 5 1/4" drive bay stack  By using optional power adapter and external SATA cable, the 3SA can be used as an external RAID storage enclosure. Constructed with aluminum for durability and efficient heat conduction, a high CFM fan system is located at the back of the unit to ensure efficient cooling of any hard drive. Combining with Addonics Serial ATA RAID controllers, high performance and reliable data storage system can be implemented at less than half of the cost of the traditional IDE or SCSI systems.

(1) Serial ATA hot swap feature works only with controllers basing on Silicon Image chip set from our inhouse testing. Other controllers that are not Silicon Image based may not support hot swap. You may consider adding one of the Addonics Serial ATA host controllers to your systems to ensure the hot swap capability. New controllers from Intel and other suppliers may finally support this feature. Please verify with your controller manufacturer if you need to have hot swap in your application. Hot swap is supported in Windows 2000 and XP only. On other OS, drive can be removed without crashing system. But replacing with a different drive can result in crashing the OS.

Power supply requirements for the Disk Array

The Disk Array 3SA is equipped with two standard 4P power connectors and a pair of 15-pin SATA power connectors on the back for easy connection to any standard PC power supply. Depending on the maximum power available from each power connection, two power connections from the same power supply may be necessary to provide adequate power for three hard drives. When connecting the Disk Array as an External device, use one optional Serial ATA power adapter for every two drives. 

 

RAID 1- Mirroring and Duplexing for fault tolerance

Features
Best suited applications
  • Improved read transaction rate
  • Full fault tolerance
    Data between two drives is mirrored in real time. Failed drive can be hot swapped and replaced with no interruption to system operation. Replacement drive is automatically rebuilt from the good drive
  • Accounting
  • Payroll
  • Any application requiring fault tolerance in storage system for high availability

RAID 0 - Disk Stripping for high performance

Features
Best suited applications
  • Data is broken into block and written to two separate disk drive. This significantly improves Read/Write performance by spreading the I/O load across the two drives
  • Video editing and production
  • Image editing
  • Pre-press applications
  • Any application requiring high performance data storage system

RAID 0+1 - Benefit of both high performance and fault tolerance

RAID 5 - Parity RAID

Features
Best suited applications
  • Parity RAID adds fault tolerance to Disk Striping by including parity information with the data. Parity RAID dedicates the equivalent of one disk for storing parity stripes.
  • Parity RAID uses less capacity for protection, reducing cost per megabyte for larger installations.
  • Accounting
  • Payroll
  • Any application requiring fault tolerance in storage system for high availability

*Note: It is common in RAID5 configuration that the WRITE speed performs slower than READ. Depending on system hardware, the WRITE performance can to 25% of the READ speed. This performance difference does not affect general database application where majority of the transations are READ commands. For applications that require large files transfer or continuous writing of data on the the hard drive such as video editing, RAID5 configuration may not be desirable.
