OCZ has introduced a Mac Edition of its Vertex solid state disk, it's available in 30GB, 60GB, 120GB and 250GB capacities. The 120GB model is the fastest one, it promises read speeds of 240MB/s, write speeds of 170MB/s and sustained write speeds of 100MB/s. You can find the full specifications over here. I assume the Mac Edition uses the same Indilinx Barefoot controller as the standard Vertex SSDs.
OCZ continues to expand its reach to all areas of computing interests and system preferences by going beyond the PC. Building on the advantages of flash-based storage, the OCZ Vertex Series Mac Edition is the result of the latest breakthroughs in SSD technology. The Mac Edition delivers the incredible performance enthusiasts have come to expect from OCZ’s premium Solid State Drive offerings with the peace of mind knowing they are tested in Apple’s own labs. Additionally, the drives feature speeds up to blazing 240MB/s sequential read and 170MB/s sequential write and 64MB onboard cache, while delivering extended battery life, increased system responsiveness, and superior durability compared to conventional hard drives.
