One of the biggest benefit of using a hybrid HDD is its ability to take advantage from both world: the storage capacity of a mechanical hard drive and low latency of a SSD. Now after more well known Seagate Momentus and Intel Z68, Apacer joins the playfield with their hybrid solution, PHFD (PCIe Hybrid Flash Drive.) The PHFD is a PCIe SSD which serves as a cache device for mechanical hard drive. The most frequently used data or programs will stays in SSD for faster retrieval by operation system, hence the improvement of overall system performance. Apart from being a cache device, PHFD can also serve as a RAID controller, arraying the SSD and hard drive to form a RAID 0 or 1 array. This somehow feels very similar to Marvell's hybrid solution, one would be left to wondering if the same technology was deployed on both solutions.
In addition to hybrid HDD, Apacer also showcases a NAS service called "Web Disk", which, strictly speaking, falls in the domain of a private cloud. All operations can done through browsers in web-based interface, consumes 8 watts per hour or more, supports multimedia playback in browser for browser-supported file formats and should be available sometime this autumn.
