I'm really finding it hard to understand the need for USB3 external hard drives when eSATA has been around for so long. I've been using eSATA for a while and couldn't be happier (especially now with Windows 7, the whole computer doesn't freeze while the drive spins up, like it did with Vista). It has the speed and hot-plugging convenience of USB. The only thing USB3 could have over eSATA is that USB3's increased power output could mean that you don't need a power brick. But if you do need one, USB3 hard drives are nothing to get excited about.

Other devices that could take advantage of USB3 is a whole other topic and could yield some interesting products.

You're kidding right? USB 3.0 has a top speed limit of 5Gb/s while eSATA is currently limited to 3Gb/s. In either case, the drive is the limiting factor here, not the interface. 5.0Gb/s is about 640MB/s. We haven't come close to drives with that speed yet. Even the best SSD drives are around the 300 to 400MB/s mark. A 7200 RPM 3.5" hard drive will SATA bench at 99 MB/s. Guess what? It benches the same on USB 3.0.

Maybe you should try one yourself and run your own tests before telling everyone how much you think USB 3.0 sucks.

First of all, I never said USB 3.0 sucks. It doesn't suck at all, it's just not interesting as far as connecting hard drives go.

Second, SATA, and thus eSATA, is currently at 6 Gb/s, not 3 Gb/s. But let's pretend it doesn't exist.

Third, you've completely missed my point. I didn't say USB3 is slower than SATA 3 Gb/s (which it is, at least with current generation chips), nor did I say that there would be any difference for the user if he used eSATA or USB3, since indeed most of the drives are the bottleneck (lets pretending SSDs don't exist either). What I said was that USB3 is not news at all - it doesn't bring anything new to the table as far as connecting external drives to your computer.

The fact is, for YEARS we've lived with USB2 and eSATA but without USB3, and for YEARS hard drives, even low end ones, have exceeded USB2's to speed (which is nowhere near 480 Mbps, just as USB3's top speed is nowhere near its theoretical max of 4.8 Gbps), and for YEARS the only good way to connect an external hard drive was eSATA.

Now our highly praised savior, USB3 has come to save us from the slow, agonizing transfer rates of USB2. Despite the fact that eSATA served us well for so long and the fact that USB3 is not even an improvement over eSATA, let's ignore all that and listen to the media hype instead: eSATA is dead! All hail the new king - USB3!

You said it yourself, there's no practical speed difference between the two, so why do we need yet another connection type? Why fragment the market?

I really wish I knew what kind of performance this will have. Is'nt SATA 6 supposed to be really fast to? I guess I'll have to wait until Intel does whatever it is they are going to do so Mobo maufactures will begin replacing the older USB and SATS
