Ask LH: Do I Need USB 3.0 In My Next Computer?

Dear Lifehacker, I really would like to replace my old computer with a new one, but the one I want doesn't support USB 3.0. I don't want to buy a machine that's already somewhat outdated. If my next machine only has USB 2.0 ports, will it be incompatible with USB 3.0 external hard drives and accessories a few years down the line? Is USB 3.0 so important that I should wait until it's available in a computer I want, or should I just buy what's available now? Thanks, USB Confused

Dear UC,

USB 3.0 is fantastic. Not only does it run at 5Gbps — 10 times faster than its predecessor, USB 2.0 — but it also corrects a lot of performance issues as well. It's all-around better, so if you can get it you should. USB 3.0 devices and ports are also backwards-compatible with USB 2.0, so you don't have to worry about a USB 2.0 machine being obsolete.

While USB 3.0 is great, you shouldn't have to worry about your computer becoming obsolete just because it doesn't have it. For example, you can use USB 3.0 hard drives with your current USB 2.0 ports. They'll work just fine, but at USB 2.0 speeds. Hopefully that puts your main concern to rest, but when it comes to buying the USB 3.0 question gets a little more tricky. In some cases, it may not be worth the wait.

The main reason you wouldn't want to wait is if you're buying a Mac (with the exception of a Mac Pro, which can have USB 3.0 ports with the help of a PCI Express card). Apple just added Thunderbolt to its new Macs, which is twice as a fast as USB 3.0. This would be great if any Thunderbolt devices actually existed. The first machines with the super-fast port were announced at the beginning of the year, and yet no devices exist. Device support will likely be paltry until Apple's exclusive hold on the technology expires in early 2012.

Chances are Apple will want to give Thunderbolt an opportunity to grow before allowing the competition of USB 3.0, so it's probably a safe assumption that you wont see any USB 3.0-compatible Mac laptops or desktops for quite a while. My guess would be about two years. Many people believe it will never happen. If you want a Mac, don't wait.

Or build a hackintosh, like this Hack Mini. It has USB 3.0 support and costs very little to build. Whether you're building a hackintosh or a Windows- or Linux-based PC, most commercial motherboards sport USB 3.0 ports.

If you're buying a non-Mac laptop or desktop and have your sights set on something specific that currently doesn't offer USB 3.0 in any way, you have a couple of options. You can wait, as USB 3.0 support in a newer model is probably right around the corner. Alternatively, buy a machine with an ExpressCard slot and get a USB 3.0 card. That may not be an ideal solution, but it's better than nothing.

All in all, definitely get USB 3.0 if you can get it. If you can't, or just don't want to wait, you'll still survive. You'll just be moving a little bit slower.

Cheers Lifehacker

    Off-topic, about ExpressCard:

    I've got a video camera which can connect to computer via firewire; trouble is I don't have any firewire ports. I have an ExpressCard port on a Lenovo S10e (netbook), so I bought an ExpressCard thingy with firewire ports and connected the camera to that. I can get the audio and video off the camera this way (using Windows Movie Maker in XP) but the audio is out of sync and not at a constant, correct, or easily correctable speed.

    Is there something I can do to make this work? Or the next time I replace my 15.6" (main) laptop, should I just make sure that the new one has a firewire port?

    Similarly, and also more on-topic: Would an ExpressCard thing with USB 3.0 ports necessarily fare any better in my S10e than the woeful experience I've had with the firewire one?

      Hugh, is the same problem appear when using direct to firewire connection? (i don't think that's problem with adapter)
      Most ExpressCard would only have up to 2.5Gbps speed. So, no.

        The problem is not present when connecting direct to a firewire port, but then that port was part of a laptop more powerful than the S10e, so yeah.

      It's a Lenovo S10e.. I wouldn't expect it to do anything but hold down paper

        That's helpful, thanks Ben.

      FireWire from your camera is not like a USB file transfer. Movie maker has compressed the audio and video in a way that it has lost sync. A proper movie program should use better codecs for the job.

    Thunderbolt? Meh. (read: new version of irrelevant-Firewire)

    I bought a 2tb 'USB3 Samsung Story Station' but when I picked it I neglected to check the HDD speed! Turns out it's 5400, it does seem to be quicker than I would expect, but I can't help the feeling a faster HDD would be a big help! Then again a 7200 2tb HDD would be kind of exy too huh? #}

    I have a USB that worked a couple of days ago in the same computer, but now it doesn't work at all. It has all my work on it!!! What should I do???
