One of the configuration options that Apple offers with its iMacs is the ability to opt for a Fusion Drive. In case the name wasn’t already obvious, a Fusion Drive is basically the combination of a regular HDD and an SSD, thus providing both regular storage and flash storage at the same time, kind of like the best of both worlds.
However it seems that in the latest Fusion Drives that Apple is offering with the latest iMacs, the Cupertino company has reduced the flash storage portion of the drive to a meager 24GB. What this means is that it is basically just enough to install the operating system on, thus giving you a faster boot time, but beyond that don’t expect to store much more.
This was spotted on Apple’s iMac specs page in which it reads, “The 1TB Fusion Drive pairs a 1TB hard drive with 24GB of fast flash — enough to store important OS X files and applications to ensure fast startup, near instant wake from sleep and quick application launching, with room left over for your most frequently used files and apps.”
Prior to this and in other versions of the Fusion Drive, Apple had included 128GB of flash storage which was pretty decent and more or less standard. However if you want the 128GB of flash, you will have to upgrade to either the 2TB or 3TB versions of the Fusion Drive which will set you back an additional $200 and $300 respectively.
