However, in this day and age, going for anything smaller than 64 GB will not bring any noticeable cost savings. ![]() How small an SSD drive could one use for solid-state cache? Sizes as small as 16 GB were initially mentioned, but that was back some 3 to 4 years ago. Used in conjunction, the two devices could create a high-performance, cost-effective storage solution combining the storage capacity of a magnetic hard drive with faster response of an SSD drive (for frequently accessed data). The whole point of this technology was cost savings, as Intel officially recommended going for the low-cost (but high-capacity) hard drive and a low-cost, small-capacity SSD. In effect, these technologies allowed using dual-drive configuration combining two separate low-cost devices: a larger (and slower) HDD with a smaller (but faster) SSD. These technologies were developed by several manufacturers including ASUS (ASUS SSD Caching) and Intel (Intel Smart Response Technology, a part of their Intel Rapid Storage Technology for compatible chip sets). A special SATA controller in the computer’s motherboard would be utilized to merge the two devices together, presenting them as a single storage device to the operating system. These are the only true SSHD’s out there that can be used in any computer with or without explicit support for hybrid storage.Įarly hybrid drives were constructed of two different physical devices, a hard drive and a separate SSD drive to be used for caching. These devices not only integrate a HDD and an SSD into a single body, but implement all the caching logic in their own microcontrollers. The third, final type of hybrid drives are true SSHD’s.Without it, these devices would appear as two separate disk volumes to the OS. These still required driver support from the operating system. The second type of hybrid devices was built on the same principle as the first, only integrating the two storage devices in one physical body.These absolutely require support from the operating system and/or a chipset on the motherboard to receive hints about which data to cache on the small SSD. ![]() The first technology involves using two individual devices, a larger hard drive and a smaller SSD, in a dual-drive hybrid configuration.While this is a vague definition, we can’t just say that SSHD’s are hard drives with a bunch of NAND flash chips to speed them up.īasically, there are three types of hybrid drives.' With the advent of true solid-state drives (SSD), manufacturers struggled with their limited storage capacity or, rather, the high cost per gigabyte of storage compared to traditional hard drives.Īs the name suggest, a hybrid hard drive (also known as SSHD, or Solid-State Hybrid Drive) is a storage unit combining the use of magnetic plates used in traditional hard drives with a faster (but smaller) flash-based solid-state media.
