The Intel X25-M G2 was a solid-state drive in the 2.5" form factor, launched on November 8th, 2010, that is no longer in production. It was available in capacities ranging from 80 GB to 160 GB. This page reports specifications for the 80 GB variant. With the rest of the system, the Intel X25-M G2 interfaces using a SATA 3 Gbps connection. The SSD controller is the PC29AS21BA0 from Intel, a DRAM cache chip is available. Intel has installed MLC NAND flash on the X25-M G2, the flash chips are made by Micron. The X25-M G2 is rated for sequential read speeds of up to 250 MB/s and 70 MB/s write; random IOPS reach up to 35K for reads and 6K for writes.
The SSD's price at launch is unknown. The TBW rating for the Intel X25-M G2 80 GB is unknown, too.

Notes

NAND Die:

The device is divided into two 16Gb planes utilized individually in single-plane
operation or simultaneously in dual-plane operation. Each plane contains
4096 blocks. Using a mixed-string driver and center-page-buffer architecture,
both the wordline and bitline RC is divided in half, which mitigates performance
degradation from doubling the density and transitioning to a smaller
lithography. Thus, each 16Gb plane is sub-divided into 4Gb partitions. The
block size is 512kB as defined by 128 pages and 4kB page size.
