be used for the swap file? If so, can there at all be circumstances where this
will actually benefit performance, say, in the case of heavy non-swap activity
of the built-in HD?
This is about increasing performance of a Fujitsu-Siemens P1120 subnotebook,
which at least officially cannot (but unofficially can?) get a RAM upgrade.
Thanks for any comments!
Re: PCMCIA swap drive
You could use a PC Card drive for the swap file. However, you would
NEVER want to do that with a flash drive, only with a real (rotating
platter mechanical) hard drive. There are two issues with flash drives:
First, they are horribly slow compared to real hard drives.
Second, they are Flash memory, and flash memory has a limited number of
write cycles before it's life expectancy is used up and it fails. While
cameras (remember, the limit applies only to writes), using flash memory
as a swap file would destroy the flash drive relatively quickly.
Also even if you had an infinitely large drive as fast as the connection
channel (for a PC Card, this would be PCI bus speeds, same as the
internal IDE hard drive), it would not be a substitute for a RAM
upgrade. Once the swap drive reaches about 2 to 3 times the total size
of RAM, a larger swap drive gives very little additional benefit.
