The nice thing with the passports is that they'll run off a single USB port more often than most others, WD quite confidently don't even supply a Y cable with their drives. They're around £75+ for 500GB, others are up to a tenner less except for Samsung who despite being so cheap for 3.5" drives are so expensive for 2.5" externals.
A DIY alternative though would be to get a 2.5" enclosure with eSATA + USB (needed for power or data) and a 500GB drive.
It's what I ended up doing. Speed of eSATA is nice but all those cables... and it's only really useful for you, any other system you use it on won't have eSATA.
USB3 is long overdue and needs to get implemented quicker, plenty of power and speed.

Yes, IMO USB3 is far more needed than SATA3, and yet SATA3 is on the horizon while USB3 is long off![]()

At least make SATA be able to be used by more than Hard Drives and Optical Storage lol.
USB3 would be so much more useful as nearly everything can or does use USB.
Is Firewire dead now?
USB and SATA are very, very different. We need them both.
Yes Firewire is pretty much dead, Apple even stopped adding ports to some laptops.
TBH I dont really need SATA3, yes it will be a lot faster than SATA2 but I can survive without it for now.
USB3 on the other hand would be more useful for me personally.
I can see how SSDs will be getting held back by SATA2 though.
Oh I see what you mean, yes most definitely, I was referring to the standards in general. eSATA seems like such a hack to make up for USB2 being so inadequate, really not suited to what most people use it for.
Yeah, its about time we got faster standards. Just like Wireless N has this moved from Draft N yet?
