Thanks to all for the info. May I say that its all rather overwhelming.

Bear in mind, though, that eSata will only be a little faster than  
FW800 (which current MBP's have built in), so you may want to  
consider whether the price of the additional card is worth it when  
compared to a FW800 drive if you have a FW800 capable MBP.  
Barefeats have some useful reports on speed comparisons of the  
different interfaces -see, for example, 


eSATA - Tempo SATA Expresscard/34 for MacBook Pro

A good back ground for SATA and ESata can be found here :-



You should read it , and there is further info at the end of the links
shown at the bottom of that page

Hi Adrian,

USB 1 is 10Mb/s
Firewire 1 is 400Mb/s

USB 2 is 480Mb/s
Firewire 2 is 800Mb/s

But there is more to it. Firewire 1 is actually faster than USB 2. See:



And as for the next generation of Firewire vs USB there is no contest!!

  Eugene

Hi Adrian,

First part of your question: Firewire is faster than USB2
http://www.barefeats.com/usb2.html
"External Serial Advanced Technology Attachment or eSATA is an  
external interface for SATA technologies. It competes with FireWire  
400 and universal serial bus (USB) 2.0 to provide fast data transfer  
speeds for external storage devices.


SATA replaced ATA legacy technology as the next generation internal  
bus interface for hard drives. The SATA interface is more streamlined  
than ATA and provides serial architecture for greater speed than the  
older parallel technology. SATA cables are narrow and can be up to  
three feet (1 meter) in length, whereas parallel cables are much wider  
and limited to a length of 18 inches (45.7 cm). With eSATA, the speed  
of SATA expands to encompass exterior storage solutions.


While eSATA reaches transfer rates triple those of USB 2.0 and  
FireWire 400, it does have one drawback. eSATA requires its own power  
connector, unlike the aforementioned interfaces. However, it is an  
excellent choice for external disk storage. Unlike USB and FireWire  
interfaces, eSATA does not have to translate data between the  
interface and the computer. This enhances data transfer speeds, while  
saving computer processor resources and eliminating the need for an  
extra off-load chip."




Bear in mind, though, that eSata will only be a little faster than  
FW800 (which current MBP's have built in), so you may want to consider  
whether the price of the additional card is worth it when compared to  
a FW800 drive if you have a FW800 capable MBP. Barefeats have some  
useful reports on speed comparisons of the different interfaces -see,  
for example,
