seven sisters came to rescue my storage problem
Last week, I mentioned that I bought a 1TB hard drive. It was just the just the hard disk itself, without the enclosure. Yesterday, the external HDD enclosure arrived - IceCube second generation (G2) Pleiades for SATA, featuring eSATA, FireWire 800 (IEEE1394b), FireWire 400 (IEEE1394a), USB 2.0 connections.
(As usual, more photos follow...)
After having connected external HDDs with USB 2.0, FireWire 400, and FireWire 800. It is without a doubt that FireWire 800 provides the best connectivity. Between USB 2.0 and FireWire 400, although the USB 2.0's theoretical maximum data rate (480MB/sec) is higher than FireWire 400's (400MB/sec). I found that data transferring with a FireWire 400 seems to be faster and more reliable than on a USB 2.0 connection.
The explanation from our trusted Apple website:
Because FireWire is processor-independent, its speed is consistent. With devices like an external hard drive, FireWire 400 actually delivers quicker performance than USB 2.0. But FireWire 800 is much faster than the other two.
It turns out that buying an external HDD enclosure with FireWire 800 connection appears to be a bit difficult. There are plenty of USB 2.0 connection cases around, and quite a few supports eSATA. Except my iMac and MacBook Pro does not support eSATA out of the box.
And there's the final setup:
There's some useless knowledge. Pleiades were the seven sisters of Titan Atlas and the Oceanid Pleione in Greek mythology. They were pursued by the hunter Orion until Zeus changed them into a cluster of stars. And in Astronomy, Pleiades is star cluster which is also called Seven Sisters.

(Well, this entry is backdated. Sorry. My excuse: I decided to use this opportunity to re-arrange my iMac's HDD... a.k.a. an Erase and (re-)Install of Mac OS X ‘Leopard’. Erase and Install is commonly known in Windows world as "clean install".)
