Power Consumption

The 520 uses measurably more power than Kingston's HyperX at idle, however it's otherwise in-line with what we'd expect from an SF-2281 based drive.

    True, but the 520 series isn't the 320 series. Intel has the 510 and 520 series to satisfy the user that desires speed, but the fact is Intel will sell more SATA II than SATA III drives for the next few years. Reply

    Maybe making fast expensive drives and selling them for profit isn't Intel's main goal. Perhaps Intel is trying to push the SSD market to the next step.

    Nowadays drives are often the biggest performance bottleneck, and so it stops making a big difference whether you buy a top of the line Intel CPU or not, or even buy AMD instead.

    But once fast SSDs start becoming more reliable and sell at closer to _commodity_ prices, then Intel can get back to selling powerful CPUs to more people.

    A marketplace full of fast expensive SSDs that BSOD and lose data and slow cheap hard drives doesn't help for such a goal.

    But helping Sandforce _eventually_ get their act together (Intel aren't doing this for free of course) might do so. They might also be concerned about Samsung.

    "Perhaps Intel is trying to push the SSD market to the next step."

    Intel has frequently done this with different technologies.So it is logical.
    In the article, Intel claimed they had 100% of staff on Intel SSD. Vendors usually do not make claims about internal employee hardware.

    Ethernet, Wifi, PCI, Legacy free, non x86 ISA (Xscale, Itanic), Fibre, PC I/O and RAM Technologies.

    They even dabbled with video conferencing years ago

    I'm in the market for a 240gb SSD in the next few months, and would love to buy a 520 series over other SF-2281/Marvell options, but right now it's a 42% price premium which is way too much.

    The 120gb has a more realistic price premium of about 25% (taking into account rebates on the 2281/Marvell drives) which I would consider, would have been nice for Intel to price the 240gb at $400-430.

    The 240gb version is $357 on Amazon right now (2/29).

    I bought the Kingston version on Black Friday for $120 after MIR. It was a great deal. Although I did worry about the BSOD (especially right after sending in the MIR). Thankfully, I haven't had any problems and it has been an excellent drive. It's unbelievably fast. Reply

    They have the 332 firmware available for download from their website. There is even a toolbox utility now but this only has SMART features and no wipe tool. Reply

    Would you expect the 120GB version to perform similar to the 60GB or the 240GB version? Or right down the middle? Reply

    Historically, 128GB drives have seemed to perform closer to the 240/256GB counterparts than the 60/64GB ones. That's just my observation, though. Reply

    It's closer to the 240GB in performance. The 60GB SF drives are really at a disadvantage, especially in sequential writes. There have been benches of the 120GB 520 for some time, but the 240GB is unquestionable faster. You might not notice the difference in real usage. You can look at Anand's 120GB roundup from last year, and the 120GB version should come out slightly ahead of the Vertex 3. Reply
