so, even though the HDD's today are racing at 7,200 RPM there isn;t an issue with them braking down due to prolonged usage? All of the retail drives say not meant for continuose use and have a rather low recomended hours per month.
There was a big hoopla about the "hours per month" thing with IBM hard drives a few months back. People got all worried and bent out of shape because their drives were alledgedly "limited" to about 7 hours of use per day. Basically when people started complaining or taking business elsewhere IBM had to come out and say basically that their IDE drives are fine for 24/7 use, but for mission-critical apps they are not recommended. I think they are mostly trying to cover their own bases, or, of course this is the more likely and more cynical theory, they really want you to not try and use an IDE drive in a 24/7 setting, instead, opting for a higher priced "server class" hard drive. The bottom line is that hard drives will run fine 24/7. And, unless you are doing something that reads/writes to the drives 24/7, I don't see there being an issue with drives running at 7200rpm, 10,000rpm or what. If they sit (mostly) idle for most of the day they aren't really doing anything.
And, to answer another question, I leave my speakers on (hassle to power them on and off) but my monitors go into standby after 20 minutes. These things would not be covered by the "Power on by mouse/keyboard" so I didn't think to mention them. (Unless you have an old style or new Vantec Stealth PSU with the additional plug on the PSU)
