Amongst the many new products Apple introduced today, they also announced a new storage option called Fusion Drive. Apple's website describes how the drive works:
With Fusion Drive in your iMac, disk-intensive tasks — from booting up to launching apps to importing photos — are faster and more efficient. That’s because frequently used items are kept at the ready on speedy flash storage, while infrequently accessed items go to the hard drive. The file transfers take place in the background, so you won’t even notice.
Some thought the drive might be Apple's implementation of a Hybrid drive which uses SSD as a caching system, but it appears that Apple's system is distinct. The MacObserver digs into some details and clarifies:
To be clear, this is not a caching concept, at least not in the current use of the word. Cache would imply that the data on the SSD is duplicated, and it's not. If you have a 1TB mechanical drive paired with the 128GB SSD, you have a 1.12 TB storage platform. This truly is the fusion of all the space on two separate disks.
In a caching solution, like Intel's, files live on the hard disk drive and are temporarily mirrored to the SSD cache as needed. In an enterprise auto-tiering situation, and with Fusion Drive, the data is actually moved from one tier to another, rather than only being temporarily cached there.
The Mac Observer reports that there are two separate drives that appear as one logical partition. As a result, if your Hard Drive fails, it could be replaced with a 3rd party drive and reconfigured as a Fusion Drive.
Meanwhile, they note that all writes take place on the SSD drive, and are later moved to the mechanical drive if needed, resulting in faster initial writes. The Fusion will be available for the new iMac and new Mac mini models announced today.

The M4 MacBook Pro models feature quantum dot display technology, according to display analyst Ross Young. Apple used a quantum dot film instead of a red KSF phosphor film, a change that provides more vibrant, accurate color results.
Young says that Apple has opted for KSF for prior MacBook Pro models because it doesn't use toxic element cadmium (typical for quantum dot) and is more...

Apple today added a few older iPhone and Apple Watch models to the vintage and obsolete products list on its website.
Apple has now classified the iPhone 6s Plus and iPhone XS Max as "vintage" worldwide. Apple considers a device to be "vintage" once five years have passed since the company stopped distributing it for sale. Apple and Apple Authorized Service Providers sometimes offer repairs...
Personally, an SSD boot drive and separate large HD seems more practical. No need to "fuse" them into one volume. Just seems like asking for trouble.
The fusion drive is just software to automatically handle that. Most consumers probably don't want to have to deal with having a boot drive and a data drive. Some things can be tricky to get onto an external drive, like iTunes and iPhoto libraries.
