PCIe has been around for a while and it offers more bandwidth than SATA. While there are solid-state drives that use PCIe for this purpose, it has not really taken off because of video card requirements.
Toshiba's OCZ Storage has hatched up some bootable solid state drives which it claims can kill off SATA bottlenecks. It uses a high-speed PCI Express architecture coupled with a sophisticated workstation-grade RAID array that virtualises the SSD controllers.
Toshiba's OCZ Storage Solutions has come up with a PCIe-based RevoDrive 350. By using PCIe the drive can push 1.8 1.8GB/s in sequential performance transfer speed and 140,000 4K random write IOPS. The drive uses Toshiba's NAND memory built on the 19nm process node.
Daryl Lang, Senior Vice President of Product Management for OCZ Storage, said that the new RevoDrive 350 is uses Toshiba flash and OCZ's proprietary Virtualized Controller Architecture (VCA) 2.0 and can improve performance while reducing the burden on host resources.
"This next generation PCIe SSD is the ideal solution for performance-minded users looking to maximize both bandwidth and density for the complete gamut of gaming, content creation and workstation applications," he said.
OCZ claims its RevoDrive 350 can withstand up ot 50GB of host writes per day for 3 years, which is the length of the warranty.
The RevoDrive 350 is available 240GB ($530), 480GB ($830), and 960GB ($1,300) capacities with support for both Linux and Windows.
