Intel boosts speed, cuts prices of solid-state drives

This is pretty exciting stuff. We just have to switch to Windows 7. :-)
I notice that the life of the drives depends considerably on write
cycles. 20GB/day 24/7 does not support a data intensive environment,
which could easly write 10-20X that much.
The X25-M drives referred to are Intel's Mainstream drives, using MLC flash.
The Enterprise grade drives are X25-E, which currently use SLC flash
(less dense, more reliable, much longer lasting/more writes). The
expected lifetime is similar to an Enterprise grade hard drive.
