I've installed Xubuntu 14.04 on a brand new Crucial MX100 SSD (CT512MX100SSD1, original MU01 firmware, no newer firmware available) on a Thinkpad W510, and saw the note in the cron.weekly/fstrim file. After running fstrim manually the first two times, I got this:
$ sudo fstrim -v / /: 498557419520 bytes were trimmed $ sudo fstrim -v / /: 0 bytes were trimmed I also ran some of Martin Pitt's load tests for a few minutes while calling fstrim -v repeatedly. No problems. Since Crucial updated the firmware to MU05 on 2014-03-25 for the affected M500, and since the MX100 drive apparently has a slightly newer controller... "These new Crucial MX100 SSD series features the Marvell 88SS9189 controller, a minor upgrade from the 88SS9187 that was found in the M500 drive." http://www.legitreviews.com/crucial-mx100-256gb-512gb-ssd-review_143984 ...I'll be brave and add --no-model-check to the "exec fstrim-all" line in the cron fstrim file.
