Apple Fusion Drive For Mac Mini

8/7/2021

Fusion Drive remains available in subsequent models of these computers, but was not expanded to other Apple devices: the latest MacBook and Mac Pro models use exclusively flash storage, and while this was an optional upgrade for the mid-2012 non-Retina MacBook Pro discontinued by Apple, it will replace the standard hard disk drive instead of. To quickly recap, Apple’s Fusion Drive was announced on October 23rd in San Jose, California, where Apple launched an updated Mac mini, a new iMac, the iPad 4, and the new iPad mini. The Fusion Drive pairs a mechanical hard drive with a solid state drive (SSD). Nov 11, 2013 The new Apple Mac Mini, updated with Intel's third-generation Core CPUs and a new Fusion hybrid hard-drive option, brings improved value and welcome speediness to the most affordable Mac.

Fusion Drive, a storage option on some iMac and Mac mini computers, combines a hard drive and flash storage in a single volume for improved performance and storage capacity. If your Fusion Drive appears as two drives instead of one in the Finder, it's no longer working as a Fusion Drive. This can happen after replacing either drive of your Fusion Drive, or using software to intentionally split them into separate volumes.

Route add for mac os x 10.8. To get a similar list of active routing entries as on Linux the following command has to be executed: $ netstat -rnThe output of the netstat command on Mac OS X is very similar to the output you are used to from Linux. The option “-r” tell netstat to show the routing table and the “-n” option as with the “route” command avoids DNS resolution.

You can continue using the two drives independently, or follow these steps to regain the benefits of having the single logical volume of a Fusion Drive.

Before you begin

If you're not sure that your Mac was configured with a Fusion Drive, or that the drive has been split:

  1. Disconnect any external storage devices from your Mac.
  2. Choose Apple menu  > About This Mac, then click Storage.
    • If you see a drive labeled Fusion Drive, your Fusion Drive is working and this article doesn't apply to you.
    • If you have a Fusion Drive that has been split, you should see two drives. One of them should be labeled Flash Storage, with a capacity of 24GB, 32GB, or 128GB. The other should be at least 1TB.

Usually the identifiers are disk0 and disk1. One of them should be 128GB or less in size. The other at least 1TB in size.
  5. Type the following command, replacing identifier1 and identifier2 with the identifiers you found in the previous step. Then press Return.

    Example: diskutil cs create Macintosh HD disk0 disk1

  7. Type diskutil cs list, then press Return.
  8. Terminal displays additional data about your drives (volumes). Find the string of numbers that appears after ”Logical Volume Group” for the volume named Macintosh HD. It's a number like 8354AFC3-BF97-4589-A407-25453FD2815A.
    Example:
    +-- Logical Volume Group 8354AFC3-BF97-4589-A407-25453FD2815A
