Standard MLC can retain your data for 12 months after you wear out the NAND, while HET MLC is specced to retain your data for only 3 months. In exchange you get 30x the number of write cycles as standard MLC. For enterprise workloads this tradeoff works quite well.
The SSD 710 will officially replace the X25-E, delivering nearly the same endurance with comparable performance, higher capacities and 40 - 50% cost savings. The 710 will be available in 100GB, 200GB and 300GB capacities.
Just like the SSD 320, the 710 employs a power safe write-cache, redundant NAND arrays to protect against NAND failures and AES-128 encryption.
A number of Intel's MLC SSDs have already been deployed in servers, the SSD 710 simply addresses some weaknesses with those drives while updating and formalizing the offering. Intel is expecting the lowest failure rate out of all of its SSDs with the 710.
