OWC VP of Software Engineering Talks APFS, T2 Chip at MacSysAdmin 2018

Watch Tim Standing, VP of Software Engineering for OWC, talk about APFS at the 2018 MacSysAdmin Conference — including the internals of Apple’s new file system, APFS, and how the T2 chip (found in the iMac Pro and 2018 MacBook Pro) is used for storage.

  • Great talk, Tim. I had a couple of power failures (my landlord’s grey water pump shorting out) that completely trashed my RAiD5 volume (softRaid Thunder Bay mini with 4x HDD).

    When i contact SoftRAID I was instructed to buy disk doctor (iirc) and a UPS. It kind of annoyed me that I was forced into this kind of solution ion, and that even without power outages I was constantly getting write warnings in the softRaid error notifications. But at least I understand a bit of the how and why now. It put me off RAID5 for now, it’s just been sitting there and I’m using SSD even for short video work.

    • Sorry: Disk Doctor-> DiskWarrior

    • The volume corruption is a “feature” of HFS+ and is fixed with APFS. Unfortunately, APFS has some major performance problems when used with HDDs – it’s fine with SSDs. Hopefully, Apple will provide a solution for APFS on HDDs in the near future.

      I would like to know if the write errors you were experiencing were while using DiskWarrior or during normal use. The former is a bug in DiskWarrior that we are aware of, the latter is something I would want to investigate.

  • Thanks Tim Standing,
    too bad Apple won’t address this never ending thread….https://forums.macrumors.com/threads/2018-macbook-pros-crashing-with-bridge-os-error.2128976/page-122

    No new Macs for me until they fix their mess, and especially own it…..
    I picked up an old 2012 Mac Pro, six core, running Yosemite, runs like a top…..cheers!

  • A shame there is still lack of full APFS documentation, which prevents DiskWarrior 6 release to rebuild APFS disks. That is a deal breaker to upgrade from macOS 10.12 Sierra.
