Rather than a supercapacitor, the Crucial M500 uses a small array of capacitors:
All of the M500 line includes hardware AES 256-bit encryption, and Micron showed us an array of small capacitors on one of the M.2 form factor drives that supported flushing of all data to the NAND in the event of a power loss--not a super capacitor as seen in enterprise class SSDs, but there's no RAM cache to flush so it's just an extra precaution to ensure all of the data writes complete.http://www.anandtech.com/show/6614/microncrucial-announces-m...
Other features that set the M500 apart also center on optimizations that are clearly holdovers from the enterprise version of the SSD. Power hold-up is provided by a small row of capacitors that will flush all data in transit to the NAND in the event of a power loss. This feature is not standard with any other consumer SSD on the market, and in enterprise SSDs power capacitors typically command a much higher price structure. Finding power loss protection on the consumer M500 is a nice surprise, and one that users will need more often than they think.http://www.hardocp.com/article/2013/05/28/crucial_m500_480gb...
