OCZ Technology has unveiled the successor to their popular Vertex 3 solid state drive at CeBIT in Hanover, Germany. Officially known as the Vertex 4, the fourth generation SSD utilizes an Everest 2 controller and synchronous MLC flash memory that’s reportedly good for speeds up to 550MB/s read and 500MB/s write and up to 90,000 IOPS (4K Random Write).
We first saw this Everest 2-based solid state drive at CES 2012 although it wasn’t called the Vertex 4 at that time. OCZ demoed the SATA 6GB/s drive for us in January using IOmeter, CrystalDiskMark and AS SSD and it performed as advertised, consistently outperforming current-generation drives like the Patriot Pyro and Corsair Force 3.
OCZ announced that they were exiting the memory game in early 2011 citing a weakness in the global DRAM industry and rapid growth in the solid state drive market. The company then acquired South Korea-based Indilinx who they previously collaborated with on the original Vertex SSD.
The Vertex 4 is the second drive to utilize technology from the acquisition and the first to use the Everest 2 platform. OCZ launched the Octane SSD in October 2011 featuring the original Everest controller and was notably the first SSD to achieve up to 1TB capacity in a 2.5-inch form factor.
OCZ hasn’t published an official release date for the Vertex 4 but we expect to see units making their way to retailers within the next few months. The drive will be available in capacities up to 2TB.
The OCZ SSD RevoDrive X2 claims read and write throughput of 740MB/s and 720MB/s. The RevoDrive X2 can use PCIe x4 courtesy of the Pericom PCI-X to PCIe bridge chip, which converts the parallel PCI-X signaling into serial PCIe. The advantage to using PCIe x4 opposed to the SATA interface is that it provides far more bandwidth. The Serial ATA 3Gb/s bus is only capable of connecting devices at transfer speeds of about 300MB/s. The RevoDrive X2 uses the PCI Express 4x bus which allows speeds of up to 1GB/s.
The Intel SSD 520 Series is aimed at performance buffs with initial SF-2281-based models offering capacities of 60GB, 120GB, 180GB, 240GB and 480GB. It also has a slim design, measuring 100 x 69.85 x 9.5mm and weighing up to 78 grams. The 60GB model packs read and write speeds of 550MB/s - 475MB/s, while the larger 120GB version provides 550MB/s reads and 500MB/s writes. The 180GB, 240GB and 480GB models are slightly faster again as the write performance is boosted to 520MB/s. Naturally, using the SATA 6Gb/s interface is essential to achieving those speeds.
