LaCie 2big Dual 2TB 301253EK 전단

*1TB (Terabyte) = 1000GB. 1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon operating environment (typically 5–10% less). Capacity also varies depending upon RAID modes.  

BIG, FAST and JBOD = total accessible capacity; SAFE 100 (RAID 1) = 50% capacity; SAFE 50 (RAID 1) = 75% capacity; and SAFE 33 (RAID 1) = approximately 83% capacity.
**The greatest eSATA burst transfer rates were found in JBOD with RAID 0 software (rates are lower in other RAID modes). Performance depends on the RAID mode. Rates vary from one computer to another 

and may vary slightly from one drive to another. Average speed is usually lower, depending on host configuration.
