This stuff sounds amazing.
Yeah, compare that to this...
Here some more info:
BTW, a couple of days ago there was a power outage, but my PC with SSD which was in stand-by mode, was not affected. So it seems that the SSD is able to retain power, even after power outage, is this normal?
Some SSDs have capacitors that smooth over short power interruptions. How long was the outage?
I don't know how long it was, I was asleep when it happened. But thanks for the info, because this explains another weird behavior. Sometimes I have to turn off my PC (with on/off button) because it keeps hanging during shutdown, but when I restart it doesn't boot up from scratch, it wakes up from standby. So apparently it retains power, even when the PC is not in standby mode?
When you shut down computer with on/off button do you just press it or do you hold it for 5-6 seconds to turn it off?
When it hangs, I have to do a "hard shut down" so this means that I have to push the power button for 5 seconds. On other machines this would mean that all power is cut off. But not with my current desktop, after I turn it on, you will see the boot screen for a second, and then it comes back from standby mode. It's the weirdest thing I have ever seen, but I think it has got something to do with the SSD that retains power, while all other components do correctly shut down when not in standby.
Well, maybe it does standby by default. Check the BIOS settings.
No, your ssd does not retain power (the capasitors can retain power for a few seconds).
The behavior/symptoms that you describe are normal and are caused by the hybrid sleep(=sleep + hybernation) of windows.
So.. Getting back on track. This new memory tech replaces DRAM and current mass storage?
Yes but the thing is, when you do a hard shutdown, the PC should be completely shutdown from power. The power-button will also stop to blink, which it only does in standby. So it's still a weird "problem", but apparently it does not have anything do with my SSD.
From what I've understood, it will make computers a lot faster because it will eliminate the bottleneck of having to write data between SSD/HDD and RAM.
No, the pc never shutdowns completely from power unless you unplug the power cord or cut off the power from the psu switch (G3 state).
Yes correct, but I think you're misunderstanding me. What I'm saying is that my desktop seems to act abnormal. Like I said, when you turn off the PC normally, then Windows will boot up from scratch. This should also happen if you perform a hard shutdown, but it doesn't. Instead of rebooting, it comes back from standby mode. But I believe it when you say it hasn't got anything to do with the way SSD's work. BTW, it seems that after a hard shutdown my system goes into G4/Hibernation mode, that would explain it.
Is it windows 7 or windows 8/10?
Shutdown in windows 7 = normal shutdown.
Shutdown in windows 8/10 if fast startup (default= enabled) is not disabled = hibernation. When you perform a normal shutdown windows 8/10 always hibernates the system unless you press and hold the shift key and the shutdown button. What is strange in your case, is that a normal shutdown does not hibernate your system. On forced shutdown the OS expects that it was shutdown normally= hibernated and tries first to load the hibernation state; if it succeeds it loads the previous hibernation state, since it does not clear the hibernation cache after a successful load, but if it fails it usually performs an auto-reboot.
Thanks for the info. It's Win 8.1, and I think you have explained it clearly. On my system, a "forced shutdown" means it goes into Hibernation.
