The lack of native chipset support for USB 3.0 has created a large demand for discrete host controllers. This upsurge in demand has compelled a number of fab manufacturers, including NEC, ASMedia, Texas Instrument, VIA and etc., to enter the market to fill the void left by Intel. Now, even smaller companies want a piece of the pie.
Fresco Logic's latest two-port USB 3.0 controller, dubbed FL1009, makes full use of PCI Express 2.0 x1. While this chip aims at notebooks, motherboards and add-on cards, it is also optimized for low-power consumption without compromising performance. Fresco Logic claims this is possible due to its GoXtream xHCI Accelerator Engine. The same architecture additionally allows each USB port to sustain full bandwidth of USB 3.0 throughput. This is quite an ambitious goal. So, how good is the FL1009 exactly? At Taipei Computex, the company has successfully demoed FL1009 capable to delivering over 350MB/s. This means you could easily run a SSD in RAID-0 mode and possibly streams uncompressed 1080p HD video simultaneously.
