Windows 8 SSD boot time

Really?
For long periods maybe but I always thought the boot process would compensate for the couple of volts running through the RAM.
Sleep is more energy efficient imo.

This is the same train of thought which makes people think that leaving a light turned on compensates for the vast amount of power consumed in turning it off and back on when needed.

A PC on standby/hibernate will continually consume 4W to 60W depending on components, where as it won't consume a huge amount more booting due to modern CPUs. Bare in mind that the monitor can be ignored as it's off when on standby or turned off, but will be on for both PCs boot and those no longer in standby/hibernate (as people want to use them).

Best of all though would simply be to get a more efficient power supply, which few people seem to have!

Sleep mode works by shutting everything down but preserving the RAM
contents, thus when you wake it up again, it just carries on from where it
let off. The power consumption is more ot less the same as when you shut
down and leave the power connected. The only problem is if the power is
interrupted, when the RAM contents are lost.

A better alternative is hibernate mode which is pretty well identical to
sleep except that the contents of the RAM are first written to a file on the
hard disk. Waking up from here causes the file to be copied back to the RAM
and then the system then proceeds as for waking from sleep. In this later
case, the power can be disconnected.

Neither should be entered without saving your work (though you can leave it
open on the desktop). Windows doesn't always recover cleanly from sleep and
hibernate can be even more flakey on some laptops.

But give it a try and see how your laptop responds. Even if it does work
OK, it is still a good idea to reboot occasionally (say once a week).

Right, this post makes me believe that Hibernate saves the current memory to the disk. Doesn't that mean that you could disconnect the power and it would be a win win?

Yes that is correct.
The hibernation file takes up about as much space as you have RAM on the hard drive, so it doesn't work as well with low capacity SSD's and lots of RAM.
 
I use hibernate on the laptop. Otherwise it takes ages to start up! The laptop is over 3 years old though. 2Gb ram, sometimes (once every 10-20 starts or so, hibernate fails!)

Main PC now has a UEFI bios, and it really does start incredibly quickly with my SSD in it. Not worth hibernating, and it only goes into standby if I forget to power it off.
 
Would like to try this with an SSD on my laptop. It has some instant boot thing that pretty much skips the whole BIOS.

true


but usually the sort of people who brag about their boot speed are the same sort of people who brag about things like ''my computers been on for 2 months solid , beat that''

Not always, I never do and I never turn my PC off.

SSDs have their benefit beyond boot times as well, this should be obvious.

Plus, my i5 drops to 1.6GHz and a low power state when idle or just surfing the net anyway as does the GPU so the power consumption is exceedingly low to begin with.

four to sixty watts? rubbish. it's almost always less than five watts, something i measured myself.
Laptops are even less - i measured the standby wattage of my laptop at about seven tenths of a watt.
