Intel Second Generation X25-M SSD Tested
 

The X25-M G2 appears to be everything Intel said it would be. It's anywhere from 0 - 40% faster than the 1st gen drive in these low level tests. I would expect to see a 0 - 10% improvement in the real world depending on applications.

Intel has really gone the extra mile with their X25-M G2. It was only a few months ago when many of us saw Intel moving away from the flash fab business, and now we're seeing 34 nm parts from them. This smaller process has enabled them to priduce a 160GB model with flash on only one side of the PCB. This means Intel can move to 320GB the instant their management decides to pull the trigger.

In our testing, we saw clear improvements in random file access, especially in the area of random writes. It appears Intel has combined the advances from the 8820 G1 firmware with a bit more of a push towards write combining. That push resulted in the greater random write IOPS, but it did introduce some minor fragmentation effects seen in my worst case scenario testing.
