You probably won't find much of any details concerning how they function, companies will black bag their methods as much as is physically possible to prevent other companies from copying their methods. Googling wear leveling is about as far as you'll get, if you ask me it's one of the many technical details about a computer that I could care less about as long as it works => Sandforce happens to make some very sophisticated SSD controllers, Googling more about them might net you some information about rough methods.I've read about wear leveling, but have not looked into the details of how it works on different drives yet
The boot process isn't limited by the hard drive primarily, it's limited by the OS itself and it's initialization functions (outside of the bios) which are by large and far clunky and slow, 80+% of that time is WAITING not actual work. This is most poignantly shown by watching a modern non-optimized version of a Linux kernel toboot on a PC and watching the text init process the entire time. All the time spent is in delay loops, waiting for some piece of hardware to init, or for some hardware detect to finish. You could optimize a Linux boot to 25% of the auto-detect time by properly configuring it.Thanks for the info. When i talk about boot speed, i mean the time it takes the OS to get up and running, after the bios has done its initialization.
It's not that i question the OS ability to boot, i can imagine that it is using low order drivers to read the HD too, it's just that many people on the web claim that their OS boots faster with the SSD, but as i said i dont see that much of a difference.
If you're worried about losing the desktop during standby due to location buy a cheap UPS one that can hold up system power for the requisite shutdown sequence, they're quiet inexpensive, and the batteries only need to be replaced every 3-5 years.I like to shut down my system rather than keep it in standby. Standby means that if during the 'off' time if the power goes out you loose your desktop and have to reboot anyway. With hibernation, you get back up and running even if the power goes out while it is off.
The LED displays are supposed to have better contrast because for one thing they can use dynamic local dimming which LCD's cant.
Yes, sure.You mean CFL's? The only difference between an LED TV and an LCD TV is the backlight, not the inherent display technology, they're both LCD based, it's a horribly bad acronym mashup. In an LED display the backlight is provided by white LED's in a standard LCD they're provided by the CFL tubes.
The dynamics are very different though. LCD monitors loose some of the blacks and you'll read about this on the web. It doesnt seem like it matters, and it doesnt all the time, but when a dark scene comes up you can see how bad it gets. The images get very hard to make out. That's because the dynamics are shifted toward the light tones, the upper color values. There are more lighter tones than darker tones even though you dont notice it all the time. Some monitors actually have a CFL that can dim to help with this.I've taken apart several LCD monitors and I see how the light spreaders work. I can see the possibility of an LED unit increasing contrast by using dynamic dimming, but even high quality standard CFL based LCD's are so high contrast it's absurd!
Yes but we're still waiting.As far as I'm concerned LED displays are a 'day late dollar short' The cost/benefit just doesn't exist. OLED displays, which pixels are generated by true LED's are so superior that once the manufactoring of them scales up (and it currently is) LCD and LED based LCD's will be obsoleted within 5 years.
I dont need one.I'm not sure why you'd avoid the use of a UPS... they're cheap.
I agree, but i dont need super super fast speed, i just need fast. If you need really fast speed that's different. It's not a necessity for me, just something interesting.Many people would disagree of your dislike of raid, there are people that will actually run raid arrays of SSDD's
Controllers for what? SSD's ? That would be nice too.As the controllers get better bulk and random access will increase substantially.
SSDD are already supplanting physical hard drives but only for fast access on mid range storage, magnetic drive density continues to go up for bulk storage if not speed.
