I don't know about Samsung or LG, but the Western Digital "green" drives are ONLY 5400 rpm, not variable. I've been using them in my computers for years with no problems. My current computer runs 24/7/365. I won't buy anything else. In fact, current TiVO PVRs use WD Caviar Green drives because of how quiet and cool they are.
The Caviar Blue series are all 7200, not 5400.
The Caviar Green list "IntelliPower" instead of the actual rpm, but they are all 5400 rpm in reality. There are no hard drives that change the speed of the platter. Speeding up and slowing down the platter would waste energy and make them more noisy. They're either not spinning, or 5400 rpm. That's about as variable as it gets. It's all marketing hype since people have had 7200 rpm drilled into their heads for so long that they think 5400 drives are inferior.
The only thing to be concerned about, and this pretty much applies to ALL current large hard drives is that they now use 4K sectors. If you intend to use these drives with XP, then you need to use the manufacturer's formatting utility because XP cannot format and align the partitions properly on these drives.
