SATA 150 on DFI Lanparty 925X-T2

I've had this computer built for almost two years now and I've never
been able to get my hard disk to run at 150 as it's supposed to. When
the computer boots it says it's only running at 100. I'm running a
Seagate Barracuda 7200.7 on a DFI Lanparty 925X-T2 motherboard.
 
Could it be that the MB only has a SATA-100 controller and to run at
150Mb/s I'd have to buy a separate controller card? If thats the case,
would it really make a noticeable difference or would I be best off
waiting to upgrade to SATA-300?

You need to give us a bit more information. You say the computer reports the
drive is running at 100. Where/When does it report this number and 100
'whats'?

If you are looking at the black and white POST screen (the first thing PC
doesn when turned on), then I suspect this is an EIDE drive, not a SATA
drive and you have it connected (correctly) to the EIDE controller on the
motherboard.

On the rear of the drive, what do the connectors look like? A small flat
cable, about 1 cm across is SATA. An EIDE cable is a ribbon cable, about
1.5 - 2 inches across and there are 40 (or is it 80) tiny wires in the
ribbon. Both power connectors have 4 wires feeding them ,but an EIDE
connector has the wires in the order yellow-black-black-red, whereas a SATA
power connector has then in the order black-red-black-yellow.

I'm thinking you probably have a PATA hard drive not SATA.
Dare I ask if it's plugged into an SATA connector on the
board?
 
The hard drive is SATA, with a SATA cable from the board and a SATA
power connector from my power supply. It reports that it's running at
100Mb/s(I'm guessing it's in Mb/s, it doesn't indicate) at the second
screen after the first post screen. I can't really get a good look at
this screen since it loads so fast, but I do notice the hard drive and
that it says 100(again I believe Mb/s). Is it possible I'd have to run
RAID on this board to get the full benefit of the hard drive/s running
at 150Mb/s?

No, the default and only supported speeds of an SATA
controller are 150 or 300. Maybe you just have a bios bug,
it's just reporting it wrong or misleadingly, and you could
probably ignore it but I would get some HDD benchmark
program that tests burst speed and see if the burst speed
you achieve is up above 100MB/s as it should be if working
properly.

On my 100MB/sec capable IDE interface, HdTach reports 91.4MB/sec as
the burst rate. I don't have any SATA in the house, as otherwise I'd
tell you what I got there. (My sustained transfer rate - the graph you
get from HdTach, begins at 60MB/sec and ends at 40MB/sec, so the cable
limit of 100MB/sec is not a problem and isn't holding me back.)

Note that early SATA drives were bridged. There was an IDE controller
board, plus an IDE to SATA converter. That combination avoided the
need to spin SATA silicon right away. Later generations of controllers
got true native SATA, and those should improve on the burst
capability a bit.

Oh, this is hilarious. The early Raptor was a bridged design :-)
If the speed freaks only knew.
