back to article Hey Intel – that new Pro 2500 SSD looks awfully familiar

Intel has announced a Pro 2500 notebook SSD that appears to differ from the previous Pro 1500 by just three comparatively trivial specifications. The Pro 1500, released in Spetember last year, has a capacity range of 80GB to 480GB, while the Pro 2500’s range is, er, 120GB - 480GB... The Pro 1500 has a 41,000 random read IOPS …

    Extra security & channel availability

    Anand Tech editor Kristian Vatto says Pro 2500 differs from Pro 15000 by "TCG Opal 2.0 & eDrive compliant plus the Pro 2500 will be available in the channel as well (1500 was OEM only)"

    PIty Intel didn't say that upfront. And, anyway, why not add these retrospectively to Pro 1500?

    it's a step backwards

    > 125mW when idle versus the 1500's 55mW idle reading

    mW count when you're talking laptops, so that's a fail. Maybe that's why they felt the big increase in model number was necessary.

      Re: it's a step backwards

      You got it backwards. It also does not help that one has to pivot the tables to actually compare anything. Here is handy table:

      Model 1500 Pro, M2: active 140mW, idle 55mW, sleep 0.2mW

      Model 2500 Pro, M2: same as above

      Model 1500 Pro, 2.5": active 195mW, idle 125mW, sleep 5mW

      Model 2500 Pro, 2.5": active 165mW, idle 55mW, sleep 5mW

      You are welcome.

        Don't blame him, the article is wrong and has the power consumptions the wrong way round.

          Make that, had them the wrong way round.

            Make that:- still semantically incorrect as per the final paragraph: "but slightly worse[should be better!!] power draw in the 2.5-inch form factor." Nice half an effort straightening out the figures.

    Thumb Up

    Strikes me that Intel have just become more confident in the manufacturering tolerances. This is the same product but with better certainty around performance following either improvements or empirical evidence of their stress testing showing it can cope.

  4. Pet Peeve

    Those power consumption numbers are pretty significant

    It's uses half the power of the predecessor when idle? That's excellent.

    I hearby revoke your techie creds

    The power alone is a significant difference on a laptop.

      Re: I hearby revoke your techie creds

      Not really, no. Idle for a laptop is around 10-25W depending on what you have inside. The savings are less than one percent (significantly less if you have an older laptop). Getting an extra minute or three on a full charge is nice, but hardly substantial.

    Intel says

    Intel SSD Pro 2500 Series supports TCG’s latest Opal 2.0 features and is a Microsoft eDrive ready solution while the Intel SSD Pro 1500 supports Opal 1.0 features and does not support Microsoft eDrive. The Intel SSD Pro 2500 Series also supports more Advanced Power Management (APM) with 5 power states and 2 thermal states.

    Self Encrypting

    Slashdot are reporting that the drive has hardware-based self-encryption.

    Consistency

    Would be interesting to see what performance consistency is like. That's more important metric today, when all SSDs are "more than fast" in every aspect, the main differentiating factor in perdormance becomes the worst case performance..

    IOPS

    I hope the figures are wrong - 48/80 R/W IOPS is pittifully bad, worse than spinning rust. I am guessing there's a "K" missing in there somewhere.

    Can't you tell?

    The Intel Pro 2500 is NEWER and it has a BIGGER NUMBER, so it must be way better. Wasn't that intuitively obvious?

    What about the price? Anybody talk about that?

    More from Intel on Pro 1500 Pro 2500 differences

    There are a few other differences between the SSD Pro 1500 Series and Pro 2500 Series.

    - The Pro 2500 Series is available in the channel (in the 2.5” form factor), while the Pro 1500 Series was not.

    - The Pro 2500 Series also includes the Trusted Computing Group’s Opal 2.0 standard (Pro 1500 Series used the 1.0 standard), as well as Microsoft eDrive. -

    Lastly, the Pro 2500 Series utilizes a second source of NAND, from SK Hynix. This SSD is the first from Intel to use a second source of NAND.

    Chris.
