    Quote from Macworld latest speed tests "The new 27-inch iMacs are available in two standard configurations. Both have 8GB of RAM and feature Intel’s quad core Ivy Bridge processors. The $1999 model sports a 3.2GHz Core i5, while the $1799 model uses a 2.9GHz Core i5.

    Both iMacs include 7200-rpm, 1TB SATA-3 hard drives, but the drives in these two iMacs we received are not identical—and neither were their performance scores. Our $1999 iMac has a Western Digital WD10EALX Caviar Blue drive with 32MB of cache. Our $1799 iMac has a Seagate Barracuda ST1000DM003 hard drive with 64MB of cache—twice the cache of the WD, and the advantage of the larger cache is evident in our test results."

    Seems strange that Apple puts the faster drive in the lower priced option. I wonder if it's the same in all of those produced? :confused:

    I've just checked my BTO iMac 27", 32GB RAM, 1TB Fusion drive and 2GB 680MX.

    The standard HDD shows as a Seagate ST1000DM003 and the SSD part of the Fusion shows as a SM128E. Maybe they put the wrong drives on their test machines, or they just have a whole store that they pick from - luck of the draw...

    Not sure what the SM128E is - presumably Apples own SSD.

    where can you actually check that? I can see that I have the ST1000DM003, but it doesn't say Seagate

    Please let this thread die. It's just random which drive goes in. My high-end 27" iMac got the faster Seagate.

    As formel1 says, the ST is a Seagate drive. It doesn't say it in System Information as it says Apple HDD instead, however i just know that ST is a Seagate drive from experience.

    It is random what drive is used on the 1TB versions but the 3TB versions only use the faster Seagate drive.

    Is it safe to assume maybe, that all the Fusion Drive equipped iMacs feature the Seagate drive? I will be getting my replacement unit within the next hours, latest tomorrow, I will check to see which HDD it has.

    Update: this unit also has the Seagate drive

    Checked my high end 27" BTO Mac (i7/3.4ghz/3tb fusion) and it also has the Seagate drive.

    I bought a 2012 27" 3.4GHz/1TB Fustion/680MX today from an Apple Store.

    It came with the Western Digital hard drive WD10EALX-408EA0

    It's a crapshoot which drive you'll get. Phooey. Not impressed.

    I have a 3.4, 1tb fusion, but a 675 and that has a WD drive as well. Perhaps with a fusion drive the size of the buffer memory is less important? :confused:

    The buffer isn't the (only) concern. The throughput on the WD is noticeably slower than the Seagate.

    Same here, so with 64mo cache.

    I have to say, but no big surprise, it feels much much more faster than my late 2009 21.5". Don't know compared to WD.

    I suppose we will never know Aplle's thinking on why they put these in. It is suggested above that it's just a random decision. Luck of the draw!? :apple:

    Same here. The original article is nonsense, AND they should know better since this isn't the first time Apple has done something like this.

    I've got the Western Digital WD-WCATRA397780 drive. My spec: 27", I7 non fusion. Im barely getting 75mb read/write speeds through the Black Magic Drive speed test software, not impressed :mad:

    Ouch... Black Magic is showing me ~165MB/s read/write with my Seagate 1TB, non-fusion.

    Can you please tell me, how much cache it shows you for the Seagate in system preferences?

    I've received my 5th iMac two days ago, and unlike the previous 4, this one has the WD for a 1 TB Fusion drive. Every time I replaced the iMac, I told Apple to make sure to put in the Seagate, but the people ordering them apparently can't do much in those terms.

    Anyways, when I told my Apple Care rep, he claimed that an engineer told him, that their vendors modify the hard drives, so they run with the same specs. Not sure if true, but in my personal real world use, gaming in bootcamp, I actually didn't notice any negative differences from the Seagate. Installation and load times appear to be the same. I can't really benchmark the speed with Blackmagic, since I have the Fusion Drive (which gives me the same speed results as in previous iMacs).

    I think/hope that at the end of the day, the WD drive doesn't have any perceivable drawbacks for me, as I would like to keep this one as my final replacement.

    In general I think that Apple should make sure to put in the same parts for every one though, we're all paying the same price for our drives/computers, Fusion or not.
