Sorry For The Wait; Here’s Three Courses At Once
The wait for new PCIe 4.0 controllers has come to an end and we should start to see some interesting PCIe 4.0 SSDs arriving on the market. Western Digital recently announced their new WD Black line of SSDs will sport an in-house designed controller and today Silicon Motion announced three new controllers, the SM2264, SM2267 and SM2267XT each designed for a specific purpose.
The SM2264 is the star of the show, designed for high end users and interesting, automotive purposes. It consists of a quad-core ARM Cortex R8 built on TSMC’s 12nm FinFET process and can handle TLC or QLC NAND. It is rated at up to sequential read/writes of 7,400/6,800 MBs respectively, and random read/write speeds of up to 1 million IOPs and will feel right at home in a new PC. It also supports Single Root I/O Virtualization (SR-IOV) which is a PCI Express Extended capability that allows the SSD to appear as multiple virtual drives; this is a feature used in vehicles to allow multiple systems to make use of a single drive.
