Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
zhang, I'm not sure what encryption algorithms Waiko was talking about, but there are many encryption freeware open apps available. I use Truecrypt. Yes it works on Vista and can use multiple encryption algorithms to ensure your safety. And, as multiple posters have stated, anything 'really' private should be kept off the web anyway. That said, it's kinda funny that many people that say they're concerned about privacy, from are wide open to invasion to a variety of methods from the low tech (non-shredded trash) to the mid tech (non-encrypted, open wireless home network) to the high (non-encrypted cellular communications), to name a few.
For that private data, you just 'have' to carry with you (instead of leaving in cyberspace), you can use an an IRONKEY flash drive.
