Firewire I find nearly pointless IMO. USB has a much more wide variety of devices associated with it.

Firewire may be faster but I have never once used it lol

How is it faster? I don't even know of any thing that transfers data at 400Mb/s let alone 800Mb/s

Even RAID 0 solid-state drive don't come close to filling up 300Mb/s worth the bandwidth.

So I think USB is fine, with no need for another "standard".

The thing is that Firewire can cap out your hard drives, while USB 2 can't.

FireWire 400 (IEEE 1394-1995)
A 6-Pin FireWire 400 connector
A 6-Pin FireWire 400 connector

FireWire 400 can transfer data between devices at 100, 200, or 400 Mbit/s half-duplex data rates (the actual transfer rates are 98.304, 196.608, and 393.216 Mbit/s, i.e. 12.288, 24.576 and 49.152 megabytes per second respectively). These different transfer modes are commonly referred to as S100, S200, and S400.

Cable length is limited to 4.5 metres (14.8 ft), although up to 16 cables can be daisy chained using active repeaters, external hubs, or internal hubs often present in FireWire equipment. The S400 standard limits any configuration's maximum cable length to 72 meters. The 6-pin connector is commonly found on desktop computers, and can supply the connected device with power.

The 6-pin powered connector adds power output to support external devices. Typically a device can pull about 7 to 8 watts from the port; however, the voltage varies significantly from different devices.[11] Voltage is specified as unregulated and should nominally be about 25 volts (range 24 to 30). Apple's implementation on laptops is typically related to battery power and can be as low as 9 V and more likely about 12 V.

FireWire 800 (IEEE 1394b-2002)
FireWire 800 (Apple's name for the 9-pin "S800 bilingual" version of the IEEE 1394b standard) was introduced commercially by Apple in 2003. This newer 1394 specification (1394b) and corresponding products allow a transfer rate of 786.432 Mbit/s full-duplex via a new encoding scheme termed beta mode. It is backwards compatible to the slower rates and 6-pin connectors of FireWire 400. However, while the IEEE 1394a and IEEE 1394b standards are compatible, FireWire 800's connector is different from FireWire 400's connector, making the legacy cables incompatible. A bilingual cable allows the connection of older devices to the newer port.

The full IEEE 1394b specification supports data rates up to 3200 Mbit/s over beta-mode or optical connections up to 100 metres in length. Standard Category 5e unshielded twisted pair supports 100 metres at S100. The original 1394 and 1394a standards used data/strobe (D/S) encoding (called legacy mode) on the signal wires, while 1394b adds a data encoding scheme called 8B10B (also referred to as beta mode).
Guess you missed that part . Thats still considerably faster than USB, and i dont think youll be running RAID off of external drives anyways.

Yet another reason why physical security is still supreme, if you have physical access, all these little safety measures and passwords are just for stalling the person till they are caught.

It is all too easy to boot off a live CD and crack the password, or take the drive, throw it as a slave in another computer, and take everything off it.

Just like that stupid "super freeze the memory and throw it in a new system then write a complicated program to go through the entire memory stack etc.." crap, none of it matters if they are holding / running away with the machine.

Yep. No matter how secure something is to remote attacks, someone with physical access to a machine can go just about anything they want.
