Most people have heard of the main two types of hard drives.
There is however a middle ground, the SSHD, or Solid-State Hybrid Drive.
What is an SSHD
An SSHD is a cross between an HDD and an SSD.
SSHDs work by saving most data to the HDD and then caching frequently used data on the flash memory.
This cache can then perform at much faster speeds than the HDD would be able to.
Despite having two storage methods in a single drive, SSHDs appear as one drive to the operating system.
A storage controller built into the hard drive manages what data is stored where to provide optimal performance.
Is it worth it?
The size of the flash memory is generally relatively small, with sizes of just 32GB being relatively common.
