Is it possible to get a converter for 2.5" to 1.8"? like the 3.5" to
2.5" converters that are everywhere...
If so, would it be possible to replace the 2.5" drive in an AJBR FM with
a 1.8" and would it then consume less power?
Because I have a 1.8" drive doing nothing (inside a broken iRiver)

Samsung says that the Flash disk consumes only 0.1W when not in use and just 0.5W under load. For comparison, a typical mobile hard drive consumes somewhere between 1W and 2W of power in seek, read and write processes and between 0.2W and 0.8W when idle. Samsung may be a bit optimistic that the SSD uses just 5% of the electricity needed to power a hard disk drive, but it is clear that SSD will provide a substantial additional amount of battery time in mobile devices. In a common model that assumes that a hard drive consumes about 10-20% of the battery power, the SSD could add about 20-40 minutes of operating time in a notebook that runs about 4 hours on one battery charge. ..."
