Hybrid Drives
Hard disk drives (HDDs) are things which normally (historically) have many moving parts within and the speed at which data can be written to and retrieved from them is dependent on the speed and reliability of said moving parts (pictures in the slideshow on this site). Although it is true that the type of interface used (IDE/SATA/SAS) has a direct effect on speed, there are also different types of drives which perform faster. Flash drives (like USB sticks or Compact Flash drives) do not have moving parts, and neither do Solid State Drives (SSDs). What’s more is now we will see emerging an even newer type of drive: The HHD.
