In 2018, Phison is looking to displace SATA even further. How does an M.2 NVMe SSD that offers at least double the performance of SATA for the same price sound to you? The E8 isn't designed to compete for any performance crown, it is designed compete for the value crown. E8 powered SSDs will deliver up to 3x the performance of typical SATA SSDs for around the same cost. Even though the E8 is only a Gen 3 x2-lane 4-channel controller that is very power efficient, it packs a big punch. In fact, the E8 cranks out enough performance to take on Intel's popular 600p series of value SSDs, and Western Digital's Black series, even though they are both Gen 3x 4-lane PCIe SSDs.

We expect to see E8 powered SSDs hitting the market very soon under the usual brand names like MyDigitalDiscount, Corsair, Patriot, Kingston and many others. Additionally, the value proposition put forth by E8 controlled SSDs is sure to catch the eye of OEM's and we expect to see a large volume of E8 powered SSDs making their way into prebuilt systems and laptops.

Phison is close partners with Toshiba and we expect to see most if not all E8 powered SSDs sporting Toshiba BiCS 3 flash arrays. Toshiba BiCS 3 is their third generation 64-layer 3D NAND Flash technology. BiCS will only come in TLC, there are no plans for MLC variants.


Of the features listed above, the feature that interests us most is the faster 1-shot programming called "Full Sequence". With Full Sequence programming, three pages can be programmed at the same time resulting in fewer steps. Full Sequence programming delivers better performance and at the same time reduces power consumption. Toshiba BiCS flash plus Phison's low cost E8 NVMe Controller sounds like a winning combination to us.

Phison was kind enough to send over an E8 powered SSD for a TweakTown preview. We will be putting the E8 reference drive up against three Gen3 x4 NVMe drives and a SATA SSD to give us some insight into what we can expect from Phison's newest.
