eSATA-600 at 6.0 Gbps while FireWire runs at 1.2 Gbps.
The number 800 is eight hundred.
800 thousand, or 800,000 is "eight hundred thousand."
To answer look at the rate that the watch is getting faster. It got 3 minutes faster in 10 hours, So every (10hrs/3) 3 hours 20 mins it gets one minute faster. We need to get 2 minutes faster to have the correct time, so it will take 2 times that much, 6 hours 40 mins, to speed up to the correct time. So 6 hours 40 mins after 8am, 2:40 pm, the watch gives the correct time.

FireWire (technically known as an IEEE 1394 interface), introduced by Apple in 1995, allows a fast connection for peripherals such as video cameras. It is similar to a USB connector. The original version is now known as FireWire 400. FireWire 800 was introduced to give faster transfer speeds and supporting longer cable lengths without loss of signal. The connectors for the 400 and 800 versions are not interchangeable but converters are available which will allow FireWire 400 equipment to be connected to the FireWire 800 port at the slower connection speed.
Firewire 800 has twice the bandwidth of the Firewire 400.The number is the throughput in Megabits.
The maximum speed of USB2 at 480M/Sec is a little quicker than Firewire 400 (IEEE.1394a) which runs at 400 M/Sec (hence the "400" bit of the name). In tests, however, FireWire 400 delivers a higher sustained transfer speed. Benchmarks suggest that hard drives connected with FireWire will copy information considerably faster than they would using USB 2.0. To achieve higher performance, FireWire requires additional circuitry in supported devices. This often makes FireWire more expensive than USB 2.0. Firewire 800 (IEEE.1394b) as the names suggests, has a peak speed of almost 800 M/Sec. Used primarily by PC musicians for recording and transferring multichannel audio at high sample rates and for digital video cameras and decks
The Canon ZR90 works with a Mac. It uses a FireWire connection so you will need a suitable FireWire cable and a FireWire 800/400 adapter if the Mac only has a FireWire 800 socket.
True. Check page 397.
Firewire 800 (IEEE 1394b) has a maximum speed of 800Mbps (Megabits per second). eSATA has a maximum speed of 3.0 Gbps (gigabit per second). So eSATA is faster. In very few scenarios [like transfering a bunch of small files], FireWire will come close, but in most scenarios eSATA will spank it hard. eSATA runs at the same speed as an internal hard drive connection, because it's the exact same thing. It just doesn't have the little L notch. Also keep in mind, some USB and FireWire speed will be lost while being converted from SATA to a signal that they can work with. The signal has to be processed for FireWire and USB to be able to use it. But FireWire 800 is faster than USB 2.0. And it's better for capturing video from cameras. USB 2.0 does a big burst then it slows down, while FireWire maintains a more constant throughput. I don't know of any video cameras that use eSATA. eSATA has been the best thing for external hard drives, until they came out with USB 3.0. It seems to be making eSATA obsolete. I still use eSATA because it's what I have, and it's about 3 times faster than USB 2.0. Also USB 3.0 is good for everything but, e SATA is still best for external hard drives, while FireWire is considered best for video.
Twice as fast.
Twice as fast.
50-85 Mbps for eSATA vs 25 - 45 Mbps firewire 400 not sure what 800 goes to but eSATA will still be faster it's just like an internal drive. eSATA is up to 6 times faster than external firewire according to the fabulous Guide to managing and maintaining your PC by Jean Andrews
