Addonics Disk Array 5SA system makes implementing sophisticated RAID technology into any computer as simple as counting 1, 2, 3. Designed to accommodate up to five 3.5" SATA or SATA II hard drives in the 5SA, each hard drive can be easily secured inside or removed from the Disk Array rack with the simple aluminum drive drawer.The Disk Array 5SA, 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.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. In addition, using the Addonics optional external Serial ATA power supply and external SATA cable, each hard drive can be removed from the Disk Array and used as external Serial ATA hard drive, allowing the convenient transfer of data to different computers! minimize
