Apple’s iMac Pro has a Thunderbolt 3 storage surprise for you

“The 2017 iMac Pro features four Thunderbolt 3 ports which have several uses. One of those uses involves external storage,” Rob Art Morgan writes for Bare Feats. “We benchmarked a few of the newest and fastest PCIe based external storage devices.”

“The best thing we learned was that the 2017 iMac Pro has dual Thunderbolt controllers for the four Thunderbolt Ports,” Morgan writes. “That’s great news! Why? When we striped dual AKiTiO Node boxes and plugged into separate TB3 ports on different TB3 controllers, that enabled us to break through the 2500MB/s single controller barrier to reach 4781MB/s!”

“You can have external Thunderbolt storage connected to your iMac Pro that equals or rivals the fast PCIe base flash internal storage. No matter what storage capacity in your iMac Pro, it’s nice to know there are speedy external options available,” Morgan writes. “They even come in BLACK so they want assault the Fung Shui of your Space Gray and Black Mac.”

  1. I am absolutely loving my iMac pro. Switched to iOS development full time from just a hobby, and upgraded my aging MacBook Pro 2012. Night and day. Using an iMac pro for 3D rendering, animations, Xcode building, asset importing is like using an iPhone. Damn near instant. Its even better than the really high end PC workstations I’m accustomed to for Windows based dev work.

  2. Except that then you’ve used up most of the TB3 bandwidth making it difficult to add a couple monitors in addition for video editing.

    Mac Pro it STILL is. Versatility is the desired goal though not saying the iMac Pro isn’t a formidable machine.

  3. “Old 2010 Classic Cheesegrater Mac Pro can still do about 5900MB/s via PCI card…

    So all that sound and fury and cost…signifying that it ‘aint’.”

    How much longer will MacOS support the cheese grater? Besides, there’s so much more to a computer’s performance than appears on the surface.

    1. > How much longer will MacOS support the cheese grater?

      That’s a fair point … but the counterpoint is to ask what’s in the latest versions of OS X that’s of value compelling for an Enterprise to update to?

      FYI, a couple of years ago, I happened to notice a PowerMac G5 still in use in a industrial production setting. It was still plugging away doing its thing (IIRC hooked up to a million dollar electron microscope).

  4. SAS in a DELL can do 12GB/s (and can be configured in about 6 six different RAID setups). Another big “Who cares?” moment for Apple. Apple needs a truly expandable Pro model.
