Now SATA3.0 interface SSD has been approaching the 6Gbps speed limits are common SATA3.0 the interface SSD has more than 550MB / S performance, showing the .interface has been seriously hampered the development of solid-state hard drive. .However, the interface for the PCI-E SSD, everything is just beginning. .

OCZ released this year, the fourth generation of PCI-E Z-Drive series of solid state storage solutions, "Z-Drive Revision 4", referred to as "Z-Drive R4", regardless of capacity, performance can be termed madness .. .Z-Drive R4 is still using the PCI-E 2.0 x8 system bus interface, and integration with OCZ's second generation of its own R & D virtual controller architecture VCA 2.0, supplemented OCZ SuperScale memory controller and four or eight SandForce SF-2582 main .controller, support for complex queries the queue structure (CCQS) and other unique queries balancing algorithm, thereby reducing the CPU processor. .

Z-Drive R4 is divided into C-Series Solid State Drive

Z-Drive R4 divided into R Series, C Series .two categories, each series also includes full-height and half-height two, the length expansion cards are standard 3 / 4. .The figure is the CM88 series, the cards are full-height, size 242 × 98.4 × 17.14 mm and weighs 283 grams, the standby power consumption of 23W, read 26W, onboard eight SandForce SF-2582 host controller, with a total capacity of 3.2TB, .performance can be sustained read and write speeds up to 2.8GB / s, random write performance 8KB 275000 IOPS, 4KB maximum IOPS 500000. .
