Just wondering if Crucial SSD drives are meant to be used as an external storage device in either a Thunderbolt or USB 3.0 enclosure. I had a Crucial M4 SSD drive before, it gave me whole bunch of drive issues on OSX, in terms of data corruption and slow speeds. When I called Crucial tech support, they told me SSD drives are not meant to be used as external storage device, something about "active garbage collection" not working if connected to Windows or OSX all the time. It needs to be connected to power over an extended period of time every so often to enable proper allocation of free space. Do you guy know if the above is true? Can I safely get an M500 SSD drived as an external storage drive? Maybe the Samsung EVO drives are better because they don't have this problem? Or do they?
