That said, this is pretty new technology, and failure of either the hard drive or SSD would be catastrophic.Īll iMacs now include USB 3 (4 ports) and two Thunderbolt ports. To revive a phrase Apple has used for a long, long time, it just works.

Best of all, this is totally transparent to the end user. The brilliance of Fusion Drive is that the operating system keeps track of your work patterns and will move files, data, and applications to the SSD or back to the hard drive based on that information. It also reserves 4 GB of space on the SSD for use as a hard drive cache. Fusion Drive treats the hard drive and SSD as a single 1.125 TB volume, storing the operating system and all included software on the SSD and initially putting everything else on the hard drive. If you want way more performance, look to the $250 256 GB SSD or the $250 1 TB Fusion Drive, which combines a 1 TB hard drive with a 128 GB SSD.

It includes 802.11ac WiFi and uses two microphones to improve noise reduction. The Late 2015 iMac offers a very decent level of performance, 8 GB of RAM (its only configuration) is very reasonable with OS X 10.11 El Capitan. Intel HD 6000 graphics is a step forward from last year’s model.įor those wanting an SSD ($250 additional) or Fusion Drive (also $250), these are available options that connect via a PCI Express interface, which outperforms the SATA Revision 3 used for the hard drive. The Late 2015 model uses an ultra-low-power 1.6 GHz dual-core Intel i5 CPU – with Turbo Boost to the same 2.7 GHz as its predecessor. Remember the seemingly underpowered iMac that Apple introduced in June 2014? They’ve updated it from 1.4 GHz to 1.6 GHz and kept it available as a lower cost alternative to the 21.5″ Retina 4K iMac.
