(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

RAID 0 - Disk Stripping for high performance

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

RAID 5 - Parity RAID

*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.
