The Phison E26 PCIe Gen 5 solid state drive controller chip measured, the access performance reached a new high

The author is lucky enough to get the Phison PS5026-E26 controller chip solid state hard drive engineering sample and conduct the actual performance test first, so that readers can see the transmission performance of PCIe Gen 5.

It supports PCIe Gen5 and NVMe

Phison’s PS5026-E26 will be one of the first controller chips on the market to support PCIe Gen 5 bus, and solid state drives from many SSD manufacturers are expected to be equipped with this controller chip.

PS5026-E26 adopts 12nm TSMC (TSMC) node process, with built-in dual-core processor and 32-bit microcontroller, supports PCIe Gen 5×4 bus and NVMe 2.0 protocol, can be matched with 3DTLC type NAND chip and QLC and supports 8 channels Transmission mode and transfer rate of 2400 MT / s, in the buffer memory part, it can be combined with LPDDR4 or DDR4 memory with transfer rates up to 3200 MT / s.

The author is very fortunate to have the opportunity to get engineering samples of solid state hard drives that are still in development this time and to take the performance test to the readers. On the other hand, why the firmware adjustment of PS5026- E26 controller chip is still in progress, after discussions with Phison team, this article can only run limited tests and publish some performance data.

After the firmware adjustment of the PS5026-E26 control chip is completed in the future, it can be expected that the performance will be improved and that more detailed tests can be performed at that time. We apologize for the inconvenience caused to the readers.

Effectively reduce game loading time

In the next part of the actual performance measurement, the author will directly illustrate the performance of the PS5026-E26 controller chip through the graph.

test platform:
Processor: AMD Ryzen 9 7900X
Radiator: MSI MEG Coreliquid S360
Motherboard: GIGABYTE X670E AUROS Master (UEFI F7b version)
Memory: G.Skill Trident Z5 Neo 16GBx2
Graphics card: NVIDIA GeForce RTX 3080 Founder Edition
Storage device: Seagate FireCuda 520 1TB SSD (system disk), Phison E26 Gen5 engineering champion
Power supply: Seasonic Prime Titanium 850W
Software environment: Windows 11 Professional Edition 21H2 (Build 22000.978), GeForce Game Ready 516.94

In CrystalDiskInfo, you can see the hard drive name is Phison E26 Gen5 and the transmission mode is PCIe 5.0 x4.

During testing, the temperature reported by the control chip reached a maximum of 78 degrees Celsius.

In the CrystalDiskMark test, the read and write speeds of the Q8T1 1M sequential access can exceed 10000MB / s and the mixed test score is 7933.19MB / s.

The 128KB sequential Q32T1 access also scores well over 10000MB / s and the mixed test score is 6725.16MB / s.

In the Q32T16 4K random access test item, the read performance is 6012.32MB / s and the write performance is 4893.64MB / s.

In terms of total read time, the Phison E26 Gen5 can reduce the read time by around 25% compared to the other 2 control groups, which is pretty impressive.

For users, a solid-state hard drive with higher transmission performance can bring the greatest benefit – reducing program opening and loading times – for a smoother and faster user experience.

The author reminds once again that since the SSD used in this test is an engineering champion and the firmware is still being upgraded, there is still room to improve the performance of the final version. previously published inAORUS Gen5 10000 SSD Series Solid State DriveThe continuous reading speed can exceed 12000MB / s, which makes people look forward to the performance of the final commercial products.
