I see that the prices on the M3 instances dropped a bit more than the prices on the M1 instances did, so they are encouraging us customers even more to move from the older HHD based instances to the newer, faster SSD based instances.
They want to retire the m1 hardware. Probably costs more per hour for power to run than the new m3 hardware.
The m3 instances were already cheaper than the m1 before (as well as faster). I assume they want to get rid of the old hardware.
M1 is older hard drives and M3 is SSD? Didn't know that
Yeah, but keep in mind it's only applicable if you use instance-based storage (which you declare when you spin up the instance). If you use an EBS mount it's a moot point.
