Intel Robson Turbo Memory Question

Yeah i'm not getting this but i think i just realised something and i'd like someone to either comfirm or deny this statement for me. From what i've been able to gather the Turbo Memory (will be called this through out the rest of this post), Is a piece of hardware up to 4GB that allows you to load your most used programs/Bootup items onto it to increase the time at which programs load/decreasing boot time. Now if someone was going to do such a thing isn't this the exact same thing as the program that makes vista a memory whore to most people the "Superfetch", i believe it's called. Since that does the exact same thing for you. So then why'd someone even go for the Turbo Memory? Am i right in my assumptions or have i just been horribly wrong.

i know on the 4GB you can chose what to load etc. But i'm basing off of the basics of the Turbo Memory/My understanding of Superfetch.

 

the idea is that the files used, particularly at boot up time, are copied onto the flash memory, which has a much lower seek time and in some cases a faster transfer rate, and copying them to memory directly from the flash drive instead of using a hard drive which has much longer seek times and at least in some instances a slower transfer rate depending on the size and locations of the files. In practice though robson as well as readyboost which is the same idea don't work all that great. Using the user pinning feature of robson to add particular files can aid in program load times, but superfecth as you said does essentially the same thing by loading commonly used apps into unused memory space. There will be more of a benefit if you happen to open a program before it's been superfetched right after bootup though, such as a web browser or something. As flash technology improves newer versions of turbo memory may have more profound performance improvements, for now in many situations unless the PC has a really crappy hard drive it doesn't do that much for you.

 

ah ok, i was just making sure that i didn't just make some extremely wrong assumption.
