Apacer is working on a hard drive cache-SSD of its own, which is similar in principle to OCZ’s Revodrive Hybrid.
Called PHFD, the cache-SSD is a full-height PCI-Express 2.0 x1 add-on card, which seats a Marvell 88SE9130 (or similar) 2-port SATA 6 Gb/s controller, with one port wired to an onboard 32 GB SSD subunit, and the other port given out as a standard SATA port (to which you plug your system HDD).
Marvell 88SE9130 includes a feature called HyperDuo, which is similar to Intel Rapid Storage Technology (RST), it handles the SSD-caching on PFHD. Apacer’s solution could end up being a cost-effective solution to systems without Intel RST.
