*RAID 10 is available in the 4-disk version only.

**Hot-swapping is not available in RAID 0 mode.

*** AFP required for full compatibility with Mac OS. 

EN 1TB (Terabyte) = 1000GB. 1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon 

operating environment (typically 10–15% less).  

Capacity also varies depending upon RAID modes. In RAID 5/5+Spare/6, the capacity varies according to the 

number of disks (more capacity with 5 disks).

Calculations are based on 5MB office presentations, an average digital SLR of 8 megapixels for RAW photos, 

and 800MB/1-hour of video (encoded in MPEG-4 or equivalent codec).



Tests performed using Intel NASPT tool in SMB file systems in RAID 0 configuration.  

PC used: Core2 Duo 2 Ghz /1 GB RAM / Network card RealTek /Crossed cable / Vista Professional.  

Performance depends on the RAID mode selected, file system used, and may vary from one drive to another.
