The ADSA3R5-E features 1 eSATA and 3 internal SATA ports, allowing the versatility of both the latest External SATA and the industry standard SATA slots. This controller provides your system with RAID5 and JBOD configurations, giving you superior performance using the standard PCI slot. This RAID5/JBOD controller supports configurations of RAID 1, RAID 0, RAID 1+0, RAID5 and JBOD. JBOD combines individual drives into one large volume to show as one drive letter.
External SATA (eSATA) connector also provides more secured cable connection, improved durability, increased EMI protection and up to 2 meters cable length. (For more detail on this new SATA external connector, please review the following white paper posted on SATA-IO.org)
With the Addonics optional Disk Array 3SA system, you can add high performance storage system rivaling the traditional SCSI storage at less than half of the cost.

*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.
*The onboard SATA controller chip is SATA II compliant and capable of 3Gbits/sec. Depending on the clock rate of the PCI BUS, the actual data transfer may not be able to reach the 3Gbits/sec data transfer.
