Ok, gloves are off.
I am generally dismayed, although not shocked, by the lack of knowledge here.
First off, what is the first thing you usually do after installing a new kernel on a recompile in linux, or any version of unix? REBOOT.
Second, what do you usually have to do to an NT box if you install, or in some cases change, services? REBOOT.
Does a RAMDISK make your computer boot faster? NO. ITS SLOWER BECAUSE THE RAMDISK HAS TO BE LOADED.
If you have infinte RAM on your PC, will it still use your disk bound swap space? YES
When you link and compile a C program on any system, will it go to disk and read your object files, libraries, and source code and make intensive use of your disk? YES Is this access sequetial or random? RANDOM.
Will an SSD with 100Mb/Sec xfer rate regarless of type of access and an access time of .03ms (yes point - zero - three, from specs on some of the SSD drives ive seen) be faster than a 15k rpm 3.8ms access Cheetah with a xfer rate between 28 and 56 mb/sec? HELL YES, ESPECIALLY ON PROGRAM COMPILES.
The original post was simply asking if any of these such devices had come down to a price point that was reasonable in my estimation (<$1000) and might be worthwhile if you are doing something like, say, developing software on your at a rate of $80/hour. I was not asking if this was reasonable for some teenager playing Quake.
People make the *bad* assumption that what they use their PCs for is what everyone else uses them for, or that their idea of 'justified expense' is the same for all cases. It is not.
