Expandable Storage via microSD

Microsoft supports expandable storage on Windows Phone 7 devices. If an OEM chooses to do so, it can implement a microSD card slot for additional storage. This is similar to what Google allows with Android, however the similarity ends here.

Windows Phone creates a JBOD span across your internal NAND and any NAND on microSD. It’s all treated as one contiguous address space, like a large hard drive or SSD. The benefit is you don’t have to manage where you put your apps, music, movies or photos. The downside is you can’t just remove/replace the microSD card in your phone.

The OS is obviously stored in a known location, however data is written linearly across both internal and microSD NAND. Your phone will still boot if you remove or swap out the microSD card, but you’ll be greeted with an error.

If you remove the card and attempt to read off of it on your Mac/PC you’ll quickly realize that you can’t. By removing the card you effectively break the file system. Microsoft provides you with a couple of other options to get data to/from the phone (which I’ll get to later) so you don’t have to rely on swapping microSDs.

You aren’t stuck with that original microSD card however. If you do a factory restore with a new microSD card installed the OS will format across it and you’ll be good to go. Obviously you’ll have to re-download all of your apps and sync all of your files but it does work.

    Check out page 26. It's dedicated completely to how the "update" process works. In short, it's more like iOS than Android....which is sounds like you'd prefer.

    Yeah I accidentally skipped that page :P
    I really hope it works out as well as Microsoft hopes it will

    Will AT be reviewing the Nokia N8 and E8 Symbian phones? Nokia is pretty obscure in the States (since they mainly sell direct from their website, with no carrier subsidy), but are pretty big in Europe and Asia.

    Anand,

    With such a glowing review from you, it's almost enough to bump Windows 7 above my initial choice of getting a blackberry. I need a physical keyboard. I'm very picky about it. You are simply a very engaging writer.

    I really hope Windows 7 mobile comes up with a superior keyboard version

    The Dell phone coming out looks like it will have a really nice keyboard, I think it is called the venue pro. Also ATT is supposed to have a keyboard phone by LG I think.

    The Venue Pro *looks* great, but it's somewhat of a monster in size and weight.

    If I weren't stuck on a T-Mobile family plan, I'd probably opt for that LG Quantum. Like Anand said, WP7's interface is extremely usable on smaller screens, and the reasonable form factor and physical keyboard likely make for a very convenient real-world user experience. The drawback is that the looks and (supposedly) build quality are sub-par.

    OMG a screenshot of me in action is on the Xbox Live page!! Woo-hoo

    That's the ugliest and least interesting home/start screen I've ever seen on a smartphone. It may be functional, but even a 6 year old crackberry looked better (and I don't like the BB). The rest of the UI doesn't look too bad, but the start screen needs some work.

    I couldn't agree more. I find it funny that people are claiming this UI is "100% right" as if everybody is going to like it. Obviously it's a matter of preference, but I just cannot see the overwhelming majority of people getting into this UI. I find it appalling to look at and couldn't imagine using it every day.

    Dont know what you're smoking but most people prefer an easy to use simple looking UI thats functional rather than cluttered eye candy.
    From the vids i've seen it seems to be the smoothest running, most functional, fastest, and natural UI on any phone to date.
