I have recently noticed that my X220 (BIOS 1.25) is not properly shutting down my SSD when I do a soft shutdown, sleep or hibernate in Windows 7. Each time the " C0 Unsafe Shutdown Count" of the SMART data is increased by 1, along with the "0C Power Cycle Count". I worry that this might degrade the SSD (or HDD) fast over long-term usage.
I have tested the SSD in another computer and the SSD doesn't have this problem.
Many tools can be used to view the SMART data, such like CrystalDiskInfo, AIDA64, SSDLife Pro, Intel SSD Toolbox etc.

Something not right there. My Intel 320 has accumulated 21 unsafe shutdowns in 8 months (T420s, so very similar platform). Have you looked in Event viewer's system Log to see if any problems are recorded?

It is worth to note that before I updated the BIOS to 1.25 my SSD Crucial M4 512GB could easily go offline (and hence a BSOD). After I updated the BIOS to 1.25 the BSOD was less frequent, but the SSD eventually died. -
Tsunade_Hime such bacon. wow
Have you ever had to power down your machine by holding down the power button? That can "dirty" your disc drive and you should get an ACPI power error in your Event Log.

i've had BIOS 1.25 in mine since before public release and my 160GB 320-series has 172 power cycles and only 2 unsafe shutdown counts.
what computer did you test your X25-E in besides the X220? have you tried rolling back to an older BIOS?
how many unsafe shutdowns had this drive logged before installing in the X220? it looks like either you've had it for a while or it was purchased used from a previous server installation.
SLC drives don't log SMART data the same way as MLC so this likely isn't an issue. i've had samsung SLC drives that showed similar anomalies yet worked perfectly fine and never failed. -
^^ Thanks for the tests! I have tested the X25-E 64GB in a desktop computer (EVGA E760) and didn't meet the problem. I also tested the factory shipped Seagate 320GB HDD in the X220 and didn't meet the problem either. It looks like the X220 and the X25-E 64GB just don't get along perfectly then At least it ease my mind that it's not my X220 faulty.
Does your X220 safely shutdown the disk when you power off, sleep or hibernate in Windows?
