What is hybrid storage or hybrid disk drive

Hybrid drive

Hybrid hard drives blend HDD capacity with SSD speeds by placing traditional rotating platters and a small amount of high-speed flash memory on a single drive.

Some of the advantages of hybrid storage products include cost, capacity, and manageability. Because only a relatively small solid-state volume is required to achieve significant performance gains, a large investment in a high-capacity SSD isn’t necessary.

Hybrid drives tend to cost slightly more than traditional hard drives, but far less than solid-state drives. And because the cache volume is essentially hidden from the OS, users aren’t required to cherry-pick the data to store on the SSD to prevent it from filling up.

Where hybrid products falter is with new data. When writing new data or accessing infrequently used bits, hybrid products perform just like a standard hard drive, and new hybrid drives have a “break-in period” while the software learns which data to cache. Due to the fact that hybrid products rely on caching software, they can also be somewhat more difficult to configure.
