SDD HD in an Air ?

[hierik]

Hey Guys

So I'm trying to figure out wether or not I should select a SDD Hard drive, when I buy my new Macbork Air and in that relation I hope you can clear something up for me.

Is it true that you have to keep a certain percentage of the memory "free" to continue the speed of SDD HD? Does it get slower when it is completely full?

Best Regards

SSD is short for "Solid State Disk", HDD (or often only abbreviated "HD") is short for "Hard Disk Drive" ("Hard Disk"), thus "SSD HD" is kinda redundant.
Btw, all 2010 MBAs have SSDs, no HDDs and no option for buying it with an HDD. Or are you talking about an older MBA?
I have an SSD and always leave 10 to 20 % of its capacity free, for the OS to swap and have enough space for other temporary data.

I know that is the logic with RAM, as the management of available memory becomes sluggish as all space is used.
