Phison Previews Next-Gen PCIe 4.0 SSD Controllers: Up to 7 GB/s, NVMe 1.4by Billy Tallis & Anton Shilov on August 9, 2019 8:00 AM EST

At FMS 2019, Phison shared the specs for its next generation of client SSD controllers. The PS5018-E18 high-end controller will be made using a FinFET process technology and promises to boost sequential read and write performance of drives to 7 GB/s. The PS5019-E19T mainstream controller will be a quick follow-up to the E13T that is currently in production but has not yet shipped in retail products.
With its PS5016-E16 chip, Phison was the first to introduce client SSD controllers with a PCIe 4.0 x4 interface and is currently enjoying its unique position on the market. The PS5016-E16 is essentially an update of the PS5012-E12 — still featuring two Arm Cortex-R5 cores, eight NAND channels rated at 800 MT/s and made using TSMC’s 28 nm process technology, but now featuring a PCIe 4.0 x4 PHY and enhanced error correction capabilities. In the coming months, Phison's entry-level NVMe controller will get a similar successor: the new PS5019-E19T will be based on the PS5013-E13T (one Arm Cortex-R5 core, four NAND channels, 28nm technology), but featuring a new PCIe 4.0 x4 PHY and thus enabling cost-effective yet fast SSDs.
Phison’s next-generation PS5018-E18 high-end client SSD controller with a PCIe 4.0 x4 interface will be significantly different from the current E16. The chip gains a third Arm Cortex-R5 core, NVMe 1.4 compliance, improved hardware security algorithms, and will be made using TSMC’s 12 FFC fabrication process.
The most important improvement in the new controllers is support for faster NAND interface speeds of up to 1200 MT/s. This is necessary to get full performance out of 96L and newer 3D NAND. For the high-end E18 this allows the controller to actually deliver twice the throughput of any PCIe 3.0 x4 drive, where the E16 can only use a fraction of the extra bandwidth provided by the PCIe 4.0 upgrade. The faster NAND interface also allows the E19T to hit sequential speeds that are slightly faster than a PCIe 3.0 x4 link can handle, despite the E19T having only four NAND channels instead of the eight channels used by high-end NVMe controllers.
Peak power consumption for both the E19T and E18 will be higher than for their respective predecessors, but that's because they are so much faster; the newer controllers will actually be more efficient.
Phison's booth at FMS included live demos of the E13T, E19T and E16 controllers, but the E18 controller was not in attendance. The low-end E19T controller will be sampling by the end of the year and is likely to show up in retail drives by the end of Q1 2020. This means that the E13T is likely to be very short-lived in the retail market. The high-end E18 will be arriving a bit later, sampling in Q1 2020 and hitting the shelves in Q3, a year after the E16 it replaces.

hojnikb - Friday, August 9, 2019 - linkwhats there to increase? sata is pretty much topped out as an interface with highend ssds (like 860pro).
svan1971 - Friday, August 9, 2019 - link4 pin molex suck. Always a pain to connect. I dread anything in 2019 requiring it. Adding that one wire to my modular power supply to run a case fan controller really pisses me off.
TheUnhandledException - Saturday, August 10, 2019 - linkSATA has overhead because it was designed to support spinning rust going back a decade. SSD don't need SATA. Making SSD work on SATA was a bit of a hack. Ultimately the SATA controller is then connected to PCIe anyways. Entry level NVMe are essentially the same cost as SATA with higher performance.
MDD1963 - Friday, August 9, 2019 - linkSo, hypothetically twice as fast as the 970 EVO Plus, and, it will only shave one quarter second from WIndows boot times or game level load times...:)
Peter_H - Friday, August 9, 2019 - linkwhy not develop, a internal usb 4.0 standard, to replace sata for HDD and SSD ?
James5mith - Friday, August 9, 2019 - linkBecause literally there is no reason to. Everything is moving to direct-board-mounting. cables in general are going away for anything but legacy SATA HDD/SSD/ODD and/or power.
TheUnhandledException - Saturday, August 10, 2019 - linkWhy? What will the usb controller connect to? PCIe. So why go SSD -> <something> -> PCIe just go SSD -> PCIe. Nothing will be better than NVMe. It is a low latency low overhead way of passing storage commands over PCIe directly.
Lucky Stripes 99 - Sunday, August 11, 2019 - linkBecause internal storage is already moving to PCIe-based solutions. The U.2 interface is basically a cabled version of the M.2 connector. It currently supports PCIe 3x2 and 3x4 and can use the NVMe storage protocol. For slower devices, you have SATA Express that can support PCIe 3x2 using cheaper cables. For everything else, you have SATA, SAS, or M.2.
p1esk - Friday, August 9, 2019 - linkWhat is the main benefit of NVMe 1.4?
