For anyone worried about the X 25–M’s ability to withstand lots of write cycles ... Calculate how long it would take you to write 800TB to the drive at a typical rate.  For most use cases that’s going to be > 5 years.  For the 160GB version, it will take 2x as much data and time to wear it down.   

This article just came out: http://www.theregister.co.uk/2009/02/20/intel_x25emmental/

and

It seems that the performance of the X25-M degrades over time, as the write levelling algorithm fragments the device into little bits. Especially under database-like access patterns.
