Hello, everyone. I'm planning on putting a 1TB mSATA Samsung 840 EVO into my 5.5 iPod video. I haven't jumped the gun on actually purchasing the mSATA, and so I've been reading a few forum posts about whether to go with 512 or 1TB. Is it true that the 512 GB (Samsung 850 EVO) would be drastically more power efficient than the 840 1TB? If so, how much of a difference is there?
