Intel X25-M offers the G2 - code-named "Postville" - to its new generation SSD. With 32-nm MLC NAND, cache and doubling capacity to 320 GB X25-M wants the G2 very fast SSDs from Samsung, OCZ rebuke & Co again. Our benchmark shows how fast the flash drive in the comparison really is. Intel produces chips for its second SSD -generation 34-nm process. Thus requiring our tested 160-gigabyte model of the X25-M G2 Postville only ten MLC NAND chips. In the first X25-M-generation, which debuted in August 2008, are required for 80 GB of capacity for 20 in the 50-nm-process-made chips. The Postville SSD achieved with the 34-nm chips a maximum sequential read rate of 254 Mbytes / s. It is therefore, only minimally above the 252 MB / s of the X25-M. When writing allows the X25-M G2 in sequential mode, a maximum of 82 MByte / s - also only slightly more than the first generation with 77 MByte / s.
