Phison breaks Windows kernel with mind-bending 113GB/sec reads using 32 x E28 Gen5 SSDs

Phison literally hits lim Windows kernel using 32 x of its new E28 Gen5 SSDs with 3 x Apex Storage X16 Gen5 AICs to push mind-bending 113GB/sed read speeds.

TL;DR: Phison's new E28 Gen5 SSD delivers up to 14.8GB/sec read speeds individually and achieves a record-breaking 113GB/sec read and 104GB/sec write speeds using 32 drives in a high-end workstation. Built on TSMC's 6nm process, it supports up to 32TB capacity with advanced error correction and low power consumption.

Phison teased its new E28 Gen5 SSD at Computex 2025, with a single drive pushing up to 14.8GB/sec reads, but the company used 32 of them inside of a Gen5 AIC card and pushing -- and yeah, wait for this -- 113GB/sec (that's 113,000MB/sec).

A single Phison E28-based SSD will pump 14.8GB/sec, but the company installed 32 x Phison E28 Gen5 SSDs across 3 separate Apex Storage X16 Gen5 AICs in a high-end workstation PC running an ASUS PRO WS WRX90E-SAGE SE motherboard using an AMD Ryzen Threadripper PRO 7985WX processor.

Once installed, those 32 x Phison E28 Gen5 SSDs were pumping speeds so fast that the company was actually hitting the absolute limits of the Windows kernel itself, with maxed-out speeds reaching 113GB/sec (or 113,601MB/sec to be exact) reads, and an equally as impressive 104GB/sec (or 104,628MB/sec to be exact) for writes. Mix loads saw an even more impressive 146GB/sec (or 146,454MB/sec to be exact).

I had to take a selfie with what has to be the world's biggest Gen5 SSD, too... fun times!

The new Phison E28 Gen5 SSD controller is fabbed on the TSMC 6nm process node, with 8-channel with 32 CEs, and capacities of up to a gigantic 32TB. We've got a quad-CPU architecture, support for 3D TLC, the Phison 8th Gen LDPC and RAID ECC, and falls into the M.2 2280 form factor.

Phison's Chris Ramseyer confirmed that the mind-boggling 113GB/sec reads using its new Phison E28 Gen5 SSDs inside of those 3 x Apex Storage X16 Gen5 AICs was hitting the actual limit of the Windows kernel, or we'd be seeing over 150GB/sec (which would be NUTS).

Totally geeked out seeing this today, nerd heaven!
