Update: Although it is mentioned in the review, I must stress that USB hubs internal and external have a good chance of not giving enough power to this device. You will know when this occurs because obviously the device won't work, but more importantly you will hear a very faint clicking sound coming from the drive. I have found that if you are running this device to your front USB panels, make sure that these USB ports are powered from the motherboard USB headers and not through an internal USB hub, if so it probably won't work off your front USB ports
With the growing amount of users armed with iPods and Digital Cameras, it goes without saying that adequate Hard Drive space is becoming more and more valuable. Most people I know are going the route of external hard drives for numerous reasons: portability, HD space, and product size.

You are right about eSATA, but as I stated in the review, I was pushing it way beyond it`s intention, the NexStar3 SATA enclosure I have came with a PCI eSATA card, so I am sure that one is blazing fast. Read review here if you missed it: http://www.feelthefunk.com/past_posts.php?sid=146
Thats the problem with externals you dont want to use them for nothing too extreme using USB externals now using eSata works way better because its the same thing as using sata internally its just a cord on the inside of your comp plugging into your sata port and it has an adapter on a pci slot on the pack of ur comp that you plug a cord into and it does speeds exactly the same it works great thats how im running my 500gig external right now is with eSata.
theres a big difference between usb 2.0 and sata.. sata has a capability of 1.5 or 3.0 Gb/s transfer speed while usb only has 480 mbps transfer speed along with that it involves the speed of the drive if you run a solid state external and use it with eSata that would be perfect because you have no speed limitations solid states are faster than regular harddrives read and write speeds. now if you using a small external hdd its probably using a laptop hdd at 5400 rpm and the read and write speeds are alot slower it could also be using memory thats built into chips on a board inside it just all depends on the kind of external you got .. I built mine myself for 120.00 I bought my own external enclosure and own hdd.. (western digital ftw)
thats my 2 cents.
Brian just be careful not to fill it up all the way, don`t want it to get too heavy for you. =o)
I bought a WD 720 gig external and it is great to add my HD vids, jpegs, mp3`s and porn. I need an external i can take to peoples houses and steal their goodies. i think ill look into one of these. Thanks Beijing
