Johnny, so I have some questions 4 U.
1.Would the flashdrive bus be the same as the boot hard drive?
No.
2.Is the flashdrive bus as fast as the boot hard drive bus?
Not likely -- unless your hard-drives are antiques.
USB 2.0 has a maximum throughput of just 480 Mbits/s (60 MB/s),
but sustained throughput is less than this (sorry, I don't have the actual
figure). Although Firewire has a slower maximum at just 400 Mbits/s
(50 MB/s) its architecture is such that its sustained throughput is
actually faster than USB 2.0. Thus it's safe to say USB 2.0 is less
than 50 MB/s.
However, even a "lowly" UDMA 5 IDE (Ultra ATA/100) drive has
a maximum throughput of around 100 MB/s, which is more than twice
as fast as Firewire's maximum, which is itself faster than USB 2.0's
sustained throughput. And 1st generation SATAs were capable of
around 150 MB/s. USB has suddenly become as clunky as a 5 1/4"
floppy.
Does the flashdrive bus work independently of the boot hard
drives bus?
Yes. However, it's more correct to say the hard drive is controlled
independently of USB devices. All hard-drives connected to the
same controller are not independent of each other, so if you
connected all four IDE drives to your motherboard's IDE interface,
they'd all be competing with each other whenever you accessed two
or more of them at once (as would occur if the paging file were on
one drive, and Windows on another).
Installing a separately controlled IDE (PCI expansion card) would
allow for independently controlled drives. Similarly if you had both
SATA and IDE drive interfaces. And since USB isn't controlled by
the IDE interface, it is independent of all hard-drives.
And lastly what is a bus?
A passenger carrying vehicle, short for omnibus (for everyone). :-)
In computing terms, it simply means a set of conductors (wires or
connectors) that connect the functional components of a computer
together, effectively creating "bus routes" or pathways for signals.
In other words, USB devices are on a different bus route to the
IDE drives, and are therefore independently controlled.
The term bus usually refers to the busses within the CPU, as well
as the busses connecting it to peripheral components, memory, etc.
The bus routes between these peripherals and the CPU are
determined by the motherboard routing.
Tip: use Google to define any other terms you're not sure of.

I have been trying to use my flashdrive as the source 4 the pagefile (a
little history: 512meg athlon 64 2.2 mhz 100 gig HD compaq laptop &
512
meg
usb flashdrive) both to increase speed and to reduce wear and tear on
the
hard drive. No matter what I set the systems/advanced/pagefile options
to,
nothing makes any difference in the way my computer runs, indicated
size
of
available pagefile space ala windows task manager, or makes the
flashdrive
L.E.D. flash like it's actually doing something.
I don't need it to work. I've just been trying for so long to do it.
It
also
seems like a flashdrive should be related to increasing your computers
total
ram just as spraying cologne on yourself is to when you really need a
shower.Not perfect but better than nothing. Does anyone know what I'm
saying?
Is there any way to do this ???
Could it be done with a bigger flashdrive?
Could it be done with more flashdrives( my baby's got 4 USB ports)
and finally why the hell am I having such a hard time finding ANYTHING
ANYWHERE abou this topic? I hope it's because it's so revolutionary
and
not
because it's so stupid!!
Um, the latter, I fear.
a) FlashDrive's do not count towards system RAM. You have 512MB
total, period.
b) USB access is generally slower than hard-drive access, making it
unsuitable for a permanent swapfile (even if it weren't a removable
media).
When only one hard-drive is available, the best place is the most-used
partition (the windows partition). If a second hard-drive is available,
the most-used partition on the least-used drive is the best.
There's only one viable solution to moving a the swapfile to another
physical hard drive and must meet these requirements. The bus system
must
not be the same as the boot hard drive, the alternate bus must be at
least
as fast as the boot hard drive's bus, the alternate bus must work
independently of the boot hard drive's bus, must be on the first
partition
on the alternate hard drive on the alternate bus, and, the swapfile must
be
the only thing using that partition.
