I bought this drive to use along with a mSATA boot drive. The reliability has been fine. Once it suddenly disconnected, but I think that was mechanical. (I have the rubber bumpers on, but reseating the drive and rebooting left everything fine.)
I have found it to benchmark (ATTO) slower than other 7200RPM drives, peaking at just under 90MB/sec vs. the 110MB/sec I get from a WDC WD5000BEKT-75KA9T0 (both in the regular HDD bay on my W520). (Not sure if one would expect a 500GB drive to be faster than a 750GB.) A benchmark can not take advantage of the flash cache the way it was designed, of course.
Not at all sure it's worth the money if not being used as a boot drive. Once I'm done with some work for which I needed the extra space, I will probably put it in a family member's computer and see what happens when used as the only drive.
Oh, and I did use Acronis Disk Director 11 to copy the partitions; no problem there.
I got 2 750GB drives, and they are working fine.
