Thank you
It states:
" Still, that refreshed silicon doesn't tell the whole story. That performance jump, we suspect, mostly comes from Apple's FusionDrive, which combines a 5,400RPM hard drive and an SSD into one volume -- similar to the setup you'll find in high-end gaming rigs. (Note: you need to configure the iMac with this feature, as it doesn't come standard.) It's a significant change, especially since as recently as last year even the most tricked-out iMacs still had spinning hard drives (7,200RPM ones, mind you, but spinning hard drives nonetheless). Here, you get a 128GB disk, and it's not just there for caching, or speeding up boot times. The difference between this and other so-called hybrid storage solutions is that by default, FusionDrive stores most everything on that SSD, including the OS and applications. (Media files might live on the HDD, since you're not as likely to open them every day.) For the most part, then, the SSD will be your primary mode of storage; it's not until you run out of space that the machine really starts off-loading content onto the slower of the two drives.
And yes, it's fast, especially compared to the HDDs in last year's models. Using the Blackmagic disk benchmark, we recorded average read speeds of 409.64 MB/s and average writes of 320.14 MB/s. We should say, too, that although we varied the stress load, simulating transfers between 1GB and 5GB, the performance remained pretty consistent. For instance, in the 1GB test, which tends to yield higher numbers than the 5GB one, our average read and write rates were only slightly higher: 412.73 MB/s and 321.93 MB/s, respectively. We also didn't see that significant a gap between our high and low numbers; read speeds, for instance, never dipped below the 390s, but also never rose about the 420s. The numbers also stayed even from one machine to the other: our two systems delivered nearly identical numbers across many rounds of testing."
Now, do you have a link to Blackmagic results for the NON fusion 7200 RPM version?
