Memory Allocation--
-
How Much RAM and How Much ROM?
RamKeeper gives you the ability to have both a RAM Disk
to quickly store and retrieve data, and a ROM Disk for
more permanent storage. You’ll need to decide how
much of the total available memory you want to use as
volatile RAM and how much as a non-volatile ROM
Disk.
Why not use all available memory as a ROM Disk?
Since the ROM Disk remains intact when you turn off
your computer, it might seem logical to allocate all
available memory as a ROM Disk. However, as
mentioned earlier, many applications need RAM for
desktop space, so you'll need to Leave some of the RAM
available for use by the system.
Is a RAM Disk now obsolete?
Almost but not quite. Because you can set the size of the
RAM Disk to 512K and 800K, there are some cases in
which a RAM Disk is very useful. Such a case is copying
disks.
If you’ve ever tried to copy a 5.25 disk or a 3.5 disk to a
RAM Disk file or a hard disk, you have probably gotten
the message:
“The two disks are different sizes, so
the contents of “YOUR DISK” will be placed in a
folder on "RAM#".
This creates a folder that you may or may not want but
more importantly, it copies the files in segments instead
of all at once.
