PCIe based SSDs have been reserved for enterprise use ever since their introduction. Generally limited by pricing, even OCZ's own forays into the PCIe SSD market have been targeted at enterprise customers. That may all change with today's announcement. Meet the RevoDrive.
This PCIe x4 card takes a pair of SF-1200 controllers and RAIDs them together, giving you roughly the performance of two SF-1200 SSDs but on a single card. Through some unique component selection OCZ aims to keep costs within 10 - 20% of a single drive. Obviously you lose TRIM support and the overall performance should be no different than a pair of SF-1200s in RAID (on a good controller/chipset), but if you need PCIe this may be an option [via anand].
