I updated the firmware on my X25-M today. It was a completely pain-free procedure. Just burn a CD, boot from the CD, say yes a few times, and reboot.

I added a new set of Bonnie++ benchmarks to my first set of Intel X25-M benchmarks.

Unfortunately, the new benchmarks aren't a good comparison. I have been using the drive for a month now and I probably have 100 GB worth of rewrites on the drive.

There were two obvious improvements. Sequential input is up 30%, and CPU usage during random seeks is down 12%.

I can't wait to try running another benchmark after I get some TRIM support in my kernel.
