  • *RC-209-EX is an upgrade version of RC-209. The only different between RC-209-EX and RC-209 is the external eSATA port. RC-209-EX is an external eSATA version which can allow you hook up more eSATA enclosures. All other parts of RC-209-EX are the same as RC-209.

    * HDD Controllers are capable to support all HDD sizes, but different OS may limited the HDD sizes that can be supported. For example, XP 32-bit supports only up to 2TB. 

    * This Model supports Optical Drive (SATA CD/DVD-ROM including Blu-ray drives.) 

    * Please avoid using "Green" drives to build the RAID. These types of drives have slower spin up time and tend to enter power saving mode aggressively. The RAID controller would assume the drives as either dropped or damaged because of time out, and the whole RAID set will become degraded or even unusable.
