recycling - is there any data that supports SSDs as more environmentally friendly?

I'm trying to come up with a case for replacing our laptop HDDs with SSDs in our IT dept. Besides saving a lot of developer time, is there any data out there to support my argument that they are more environmentally friendly? Esp. with regard to construction and power consumption. Can you think of any thing that I'm missing?

Update1: I am routinely slowed down by my HDD. I'm on a laptop so my swap file is sitting on a 5400 rpm hdd. I typically sit at 80% memory used when developing so I hit the swap a lot. I have the option of going to a 64b OS (minimal gain really, considering I only have 1 mem slot free) or upgrading to an SSD. So I'm losing time already all the time. So assuming I will replace the drives, is there an environmental bonus over the long term to replacing the drive?

Update2: What about power over a year? How much power would a laptop consume being used 40 hours a week and hitting the swap very frequently on a HDD vs. SSD?

Answer

No; they don't save (as much) power as you might expect. See Tom's Hardware's analysis on SSD vs. HD power specifically this page. At least for laptops under Windows.

Update 12/2011: "A disk-based drive will always consume more power absolutely. At the system level, an SSD increases power consumption because CPU and memory utilization rises in response to increased I/O activity (they're not sitting there, waiting on a hard drive to send data)".
