Boot Drives - Translate to dollars (TCO), Datacenter buying 25K servers/year, Save 7.61W per drive by moving to SSD, Servers are powered 24/7, Savings below does not consider cooling. These savings assume 100% idle and do not include any savings due to decreased cooling costs. Are SSDs a cheaper, greener, option for your boot drive? Oh, and did I mention SSDs happen to be faster? Decisions that affect power - Faster performance doesn’t necessarily mean more power.
