Marvell is notorious for being the first to bring a 6Gb/sec SATA controller to market, and they continue to do very well in that area. Their very capable 88SS9189 controller powers the Crucial MX100 and M550, as well as the ADATA SP920.
Today they have announced a newer controller, the 88SS1093. Despite the confusing numbering, the 88SS1093 has a PCIe 3.0 x4 host interface and will support the full NVMe protocol. The provided specs are on the light side, as performance of this controller will ultimately depend on the speed and parallelism of the attached flash, but its sure to be a decent performer. I suspect it would behave like their SATA part, only no longer bottlenecked by SATA 6Gb/sec speeds.
More to follow as I hope to see this controller in person on the exhibition hall (which opens to press in a few hours). Full press blast after the break.

Apologies as there was no photo to be taken - Marvell had no booth at the exibition space at FMS.
Introduction, Specifications and Packaging
Intel has a nasty habit of releasing disruptive technology, especially in the area of computer storage. Among the first of those releases was the X25-M, which was groundbreaking to say the least. At a time where most other SATA SSDs were just stopgap attempts to graft flash memory to a different interface, Intel's SATA SSD was really the first true performer.
With performance in the bag, Intel shifted their attention to reducing the cost of their products. The next few generations of the Intel line was coupled with leadership in die shrinks. This all came together in the form of SSD releases of increasingly reduced cost. Sure the enterprise parts retained a premium, but the consumer parts generally remained competitive.
Now Intel appears to have once again shifted their attention to performance, and we know it has been in the works for a while now. With the SATA bottleneck becoming increasingly apparent, big changes needed to me made. First, SATA, while fine for relatively high latency HDD's, was just never meant for SSD speeds. As SSD performance increased, the latencies involved with the interface overhead (translating memory-based addresses into ATA style commands) becomes more and more of a burden.
The solution is to not only transition to PCIe, but to do so using a completely new software and driver interface, called NVM Express. NVMe has been in the works for a while, and offers some incredible benefits in that it essentially brings the flash memory closer to the CPU. The protocol was engineered for the purpose of accessing flash memory as storage, and doing so as fast and with the least latency as possible. We hadn't seen any true NVMe products hit the market, until today, that is:
Behold the Intel SSD DC P3700!
