Power Consumption
Intel's SSD DC S3700 can draw power on both 12V or 5V rails. Most 2.5" SATA drives pull from the 5V rail, however the S3700 seems to prefer the 12V if both are attached. The S3700 was the only drive I tested that drew any current on the 12V rail (and none on 5V), everything else was exclusively 5V. If your server supports it, Intel claims the S3700 can pull on both rails simultaneously.
As I alluded to in our S3700 architecture analysis piece, the Intel SSD DC S3700 draws quite a bit of power under load. It's easily the most power hungry Intel enterprise SSD, and it's the worst offender in all but one of our tests. The added power consumption isn't significant enough to be a problem in the datacenter, but it will likely keep the S3700 (or a not-HET derivative) from being a good fit for notebooks. Desktop use is another matter entirely, but Samsung's SSD 840 Pro controller's amazing idle power consumption is a perfect fit for mobile use. I suspect what we're seeing here is the result of Intel's focus on the enterprise market: the S3700 controller was just not built for mainstream mobile client use.
