Apple has begun offering customers ordering the entry-level 21.5in iMac the option to upgrade to the new Fusion Drive, a build-to-order feature only previously available for high-end versions and the 27in iMacs.
First spotted by French blog MacGeneration, the Online Apple Store now gives customers new build-to-order options when purchasing a 21.5in 2.7GHz iMac, allowing them to add a 1TB hybrid Fusion Drive for an additional $300.
Since their launch in October, the 21.5in 2.9GHz iMac and the 27in models of the iMac have been compatible for the 1TB Fusion Drive option, and a $480 3TB Fusion Drive upgrade is available for the 27in models only.
Apple’s new Fusion Drive is a hybrid drive that merges a 128GB flash drive with a hard drive – all into a single volume.
Our tests of the iMac (and also the Mac mini) with the Fusion Drive have shown that the new technology can give the computers a big speed and performance boost.
