Does sleep mode really damage SSD's?

[Phil2008]

Well hibernate performs very poorly with ssd's as I said in a few posts above

Actually sleep mode is really bad for SSDs.

You see, when the computer goes to sleep, it sends lots of ZZZZZZ commands. The SSD sees these as 2s (because Z and 2 look alike), and as we know, computers only use 0s and 1s.

So when the SSD starts putting the 2s in the drive, it takes up twice the amount of room (because 1 + 1 = 2).

When the computer comes out of sleep mode, it tries to read the SSD and finds lots of 11s from all the 2s it couldn't fit in, and it causes corruption.

?? A hdd or ssd doesn't do anything when it goes in and out of sleep if the hiberfill.sys is disabled , it just powers on and off the ssd or hdd...

Whoosh!

those with 16gig ram and using hibernation will probably feel stupid having the ssd write 16gigs of data from ram and then back to ram on resume,
the time it takes to write 16gig or probably 8 gig at that would be faster to do a complete shutdown and then power back on.

my nettop media pc is always using sleep mode which is suspend to ram and i have no issues going in and out of sleep mode on it, and the number of sleep and resumes can end up in double digits on weekends. i get no problems but then again im using a plextor m3 which is renoun for having best stability when it comes to this sort of usage.

 

[anything I don't mind]

I had a ocz vertex 1 fail on me because it was being used by a guy at work who ignored my warnings and had enabled sleep and hibernate and set all the power management back to default.

Yeah your safe as houses now, as I dont like the idea of sleep writing and deleting huge chunks of data to my ssd everytime I use it and I do use sleep a lot of times during the day, now that energy is a total rip off.

You could try stopping your usb hub from powering down, that the mouse is connected to when you use sleep, in the device manager.

May try this when I get time ...

I have 18 things under USB controllers in device manager, any easy way of finding which it is?

And when I do, is the option I'm looking to change, under properties, then power management then untick 'allow the computer to turn off this device to save power'?

Thanks!

allow the computer to turn off this device to save power

How much power are we talking about saving here.....

 

[Broken Hope]

Anyone using Windows 8 who's really anal about writes should make sure you have fast boot disabled under power settings.

He wants to burn more coal not less to see if the hub powering down might be affecting his mouse on resume.

Its not as if the kernel is being written to the SSD that often though, just when you turn the machine off, so is it really likely to shorten the life of the drive by any appreciable amount?

I have one of these power monitor plug in things and it says both standby and shutdown uses the same wattage, about 2watts

 

[Cyber-Mav]

standby uses 6 watts more for me than full shutdown does.

makes sense to me since the ram is still powered on, and depending on how many sticks you have and the voltage and speed they running at

Ah with my old pc both were about the same

Just tested it again, mouse scroll was fine after resuming from sleep

Haven't changed any settings either

Will continue to sleep the computer then ... Maybe the mouse issue was something else
