Anandtech reports that Intel’s new SSDs that incorporate 25nm Flash will have 4x the lifespan rating

This blog previously reported that Intel will be rolling out new versions of its highly regarded X25-M SSDs. These new drives will incorporate 25nm MLC Flash devices. Now, Anandtech has reported some interesting specs. Maximum capacity is up from 160 to 600 Gbytes. Sequential read performance is unchanged at 250 Mbytes/sec but write performance will jump from 100 to 170 Mbytes/sec and the read/write IOPS ratings jump from 35K/80.K to 50K/40K. Perhaps the biggest surprise is a quadrupling of drive lifespan, from 7.5-15 Tbytes to 30-60 Tbytes for 4Kbyte random writes. One thing that’s not going to be upgraded is the 3Gbps SATA interface.
