    Finally light of performance improvement is shed on eMMC, right? (mm, bad pun)

    I hope smartphones and tablets won't be bothered by slower-than-USB2.0-memorysticks eMMCs in near future. My smartphone's storage is almost 5MB/s or less even in sequential reads...

    Yes, it would be nice to have everything but the most budget devices be able to turn out decent storage performance.

    Equally nice would be if certain manufacturers (Apple foremost among them) stopped charging $100 for an extra $10 of flash.

    why should they? The market has proven time and time again that they are willing to pay that amount. If there was a manufacturer that thought they could make more money by giving you more memory per dollar, they would Reply

    Would be nice if some of those devices also had USB 3.0 ports, otherwise those higher sequential speeds are of more limited use... Though I'm not sure how consumers and the market would react to the larger micro port (kind of a step back ergonomically, although I guess they can always fall back on USB 2.0 for charging). Is there an OTG spec for USB 3.0? Reply

    Awesome. This should greatly improve the experience on Win8 tabs. Hopefully this stuff is getting into tablets right away. Reply

    Thanks for the update! Anand, what are your thoughts on eMMC vs. a real SSD using M2 or one of the newer small form factors? Is it pricing? Or the interface? (likely both) I'd pay an extra $20 to finally get SSD performance on my tablet. Everything on my old N7 crawls to a halt when it's downloading or updating applications. The music stutters or stops, the UI freezes on and off, response to power and volume buttons is really poor. It has quad cores, but my guess is that the storage gets swamped by the simple update process and everything else starves. It's a real poor user experience IMHO. Reply

    I think the problem is that "real" SSDs use too much power (in comparison). Reply

    Are you running it near it's storage capacity limit and did you run the most recent update? Reply

    Yup, I have 1GB out of 8GB free, and the latest update for hopefully for auto-trim. Thanks for the good thoughts, probably time for an upgrade. I'm just not sure if it's the storage that needs radical improvement or the latest Android upgrades slowing down the CPU. Reply

    In the short term, phone/tablet SoCs only offer eMMC controllers. Long term isn't just more power; but that going from a single eMMC chip to an SSD controller, ram for the controller, and 2 (minimum) flash chips would take up too much PCB space. eMMC is a one chip solution not just for cost/power reasons but also because there isn't space in a phone for anything more.

    Thanks - I forgot about space/integration costs! I wonder about some of the new USB3 storage keys. They're compact & fast, but may not handle multiple access as well. Perhaps an alternative to eMMC? Reply

    I wonder how much these would cost compared to Samsung's. Samsung's eMMC 4.5 chips have 150/60 MB/s sequential reads/writes and 3500/1500 read/write IOPS. Reply

    These numbers don't seem any better than what the new xiaomi has promised.
    I mean, isn't NAND+eMMC controller just, well, the normal situation? Is the difference that it is a single package?
