It may seem hard to believe, but storage makers are already approaching the limits of the PCI Express 4.0 bus in a typical NVMe drive, with the latest controller designs pushing transfer speeds in the neighborhood of 7 gigabytes per second (GB/s). That being the case, Silicon Motion is already at work developing controllers that leverage the PCI Express 5.0 bus. Before we get to that, let's go over the bandwidth limits of each PCI Express specification to date, starting with PCI Express 1.0... PCIe 1.0: 2.5GT/s transfer rate, 250MB/s per lane bandwidth, 4.0GB/s x16 bandwidth PCIe 2.0: 5.0GT/s transfer rate, 500MB/s per lane bandwidth, 8.0GB/s x16 bandwidth PCIe 3.0: 8.0GT/s transfer rate, 1GB/s...

Following the release of the AMD Ryzen 3000 desktop processor family, and complementing X570 motherboards, PCIe 4.0 SSDs have been sought after by enthusiasts looking for some extra performance. There aren't many companies out there making PCIe 4.0 SSD controllers, so when new products are announced, we definitely take notice. Such is the case today with three new PCIe 4.0 SSD controllers that are coming from Silicon Motion (one of which we've already heard about). The first is the 8-channel SM2264, which is aimed squarely at the enthusiast market for those craving the ultimate in performance. According to the company, the SM2264 features a quad-core ARM R8 CPU directing four lanes of 16Gb/s...

USB 3.0 offers excellent performance characteristics for external storage, but thumb drives that take full advantage of the standard have been few and far between. According to Silicon Motion, its upcoming SM3267 controller will boost single-channel USB 3 speeds for flash drives to 160MB/s read, 60MB/s write, while simultaneously cutting power consumption and reducing chip complexity. Compared to the older SM3260, the SM3267 chip supports just single-channel flash, but integrates the clock chip onboard. "We are very excited to introduce SM3267, our first crystal-less USB 3.0 solution with integrated power ICs," said Wallace Kou, President and CEO of Silicon Motion. "SM3267 offers superior performance...
