The Crucial/Micron M500 Review (960GB, 480GB, 240GB, 120GB)by Anand Lal Shimpi on April 9, 2013 9:59 AM EST
The M500 supports the new Device Sleep standard which will see platform support with Haswell this year. Crucial claims DIPM enabled idle power as low as 80mW, however even with DIPM enabled on our testbed we weren't able to get anything south of ~1W at idle. I'm digging to see if this is a M500 issue or one specific to our testbed, but Crucial is confident that in a notebook you'd see very little idle power consumption with the M500. Supporting DevSleep is important as that'll quickly become a must have feature for Haswell notebooks.
Load power looks excellent, which gives me hope that Crucial's idle power is indeed as good as they claim. The M500 is a direct competitor to Samsung's SSD 840 Pro when it comes to power consumption under load. Given how power efficient the 840 Pro is, the M500 is in good company.
