Here is an example of hardware technology advancing to solve problems which some software has developed complex features for.

From an announcement on Tom's Hardware site

"...The Z-Drive is available in multi-level cell (MLC) and single-level cell (SLC) models in 256 GB, 512 GB capacities. A 1 TB model is also available for the p84 only.

The MLC-based p84 features a max write of 650 MB/s, a max read of 750 MB/s, while the faster SLC e84 has a max write of 750 MB/s and max read of 800 MB/s. ..."
