hhaa, so the 160GB x25-m uses 4 links per die which is what makes it faster then the dual link 80GB G2.
the X25-E goes with 10xquad 2GB die packages, each for 8GB and another dual one with 4GB, for a total of 84GB (20GB spare area),
and that is what is making it so expensive!
great!
E:
G1 vs G2 160GB:
the SSD relapse AnandTech!More memory means that the drive can track more data and do a better job of keeping itself defragmented and well organized. We see this reflected in the "used" 4KB random write performance, which is around 50% higher than the previous drive.
Intel is now using 16GB flash packages instead of 8GB packages from the original drive. Once 34nm production really ramps up, Intel could outfit the back of the PCB with 10 more chips and deliver a 320GB drive. I wouldn't expect that anytime soon though.
