One of the areas that can see an immediate impact from PCI Express Gen 4 which will first arrive with AMD’s upcoming Ryzen desktop processors is storage, and to that end Phison is not waiting around to show just what we can expect from the first generation of PCIe Gen4 SSDs.

The company’s PS5016-E16 controller was on display at CES in a prototype device, and is powered by a quad-core solution combining two ARM cores with a pair of proprietary CO-X processor cores from Phison. Basic specs from Phison include:

  • PCIe Gen4 x4 NVMe
  • 8 Channels with 32 CEs
  • NAND interface: 800 MT/s support
  • DDR4 interface: 1600 Mb/s support
  • 3D TLC and QLC support
  • Designed with Phison’s 4th Gen LDPC Engine

As to performance, Phison lists sequentials of 4000 MB/s reads and 4100 MB/s writes, while providing a graphic showing CrystalDiskMark results slightly exceeding these numbers. How can Phison exceed the potential of PCIe Gen3 x4 with this early demo? As reported by Legit Reviews Phison is using a Gen4HOST add-in card from PLDA, which “uses a PCIe 3.0 x16 (upstream) to PCIe 4.0 x8 (downstream) integration backplane for development and validation of PCIe 4.0 endpoints”.

The Phison PCIe Gen4 x4 NVMe controller is expected to hit the consumer market by Q3 2019.

OCZ Announces New Indilinx Barefoot 3 Controller

During a recent earnings call, OCZ CEO Ryan Petersen made an interesting announcement relating to the company’s solid state drives (SSD). Specifically, it concerns OCZ’s subsidiary company Indilinx which was purchased in 2011 for $32 million of OCZ common stock. According to a transcript provided by SeekingAlpha, OCZ is working on a new SSD based on the company’s Barefoot 3 controller. That controller is especially intriguing because it is reportedly being internally-developed and will use a new Aragon SSD processor which is a controller chip running at 400 Mhz with an optimized and custom RISC instruction set.

The Aragon core is further a 32-bit chip based on TSMC’s 65nm process node. It is using certain IP that is being licensed from an as-yet-unnamed third party. Allegedly, it is able to execute most instructions and branches in a single clock cycle. Bearing in mind that this is an announcement to shareholders, OCZ has stated the following about the new controller:

“When implemented in SSD controller, this gives the core a much higher performance than when using an off-the-shelf embedded safety field. And this design opens a world of new possibilities for game changing SSD solutions as it supports unprecedented levels of processing power.”

Beyond that we do not know what kind of performance to expect from the drives, but we should not have to wait too long to find out. OCZ should begin sampling the drives sometime between August and September of this year and are hoping to make them available for purchase by the holiday shopping season in Q4 2012.

It will be interesting to see where this new OCZ/Indilinx controller stands in relation to the other controller makers. Here’s hoping that it can give SandForce and Intel a run for their money and give us even more competition to drive down SSD prices for consumers!
