Phison PS5026-E26: The first controller chips support PCIe Gen 5.
Phison E26 PCIe 5 solid-state drive controller chip: Performance reached a new high.
The expert in Taiwan is lucky to obtain the solid-state hard disk engineering sample of the Phison PS5026-E26 controller chip, and conduct the actual performance test first, so that readers can see the transmission performance of PCIe Gen 5.
Supports PCIe Gen5 and NVMe
Phison’s PS5026-E26 will be one of the first controller chips in the market to support PCIe Gen 5 bus, and it is expected that many SSD brand manufacturers’ solid-state drives will be equipped with this controller chip.
PS5026-E26 adopts TSMC (TSMC) 12nm node process, with dual-core processor and built-in 32bit microcontroller, supports PCIe Gen 5×4 bus and NVMe 2.0 protocol, can be matched with 3DTLC and QLC type NAND chips, and supports 8-channel transmission Mode and 2400MT/s transfer speed, in the buffer memory part, it can be matched with LPDDR4 or DDR4 memory with transfer speed up to 3200MT/s.
The author is very fortunate to have the opportunity to obtain engineering samples of solid-state hard drives that are still under development this time, and to bring the performance test to the readers.
On the other hand, because the firmware adjustment of the PS5026-E26 controller chip is still in progress, after discussions with the Phison team, this article can only perform 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 more detailed tests can be carried out at that time. Sorry for the inconvenience caused to the readers.
The overall picture of the Phison PS5026-E26 control chip can be clearly seen from the schematic photo.
Effectively shorten the 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 chart.
Test Platform:
- Processor: AMD Ryzen 9 7900X
- Cooler: MSI MEG Coreliquid S360
- Motherboard: GIGABYTE X670E AUROS Master (UEFI Build F7b)
- Memory: G.Skill Trident Z5 Neo 16GBx2
- Graphics Card: NVIDIA GeForce RTX 3080 Founder Edition
- Storage Device: Seagate FireCuda 520 SSD 1TB (system disk), Phison E26 Gen5 engineering sample
- Power supply: Seasonic Prime Titanium 850W
- Software environment: Windows 11 Professional Edition 21H2 (Build 22000.978), GeForce Game Ready 516.94
▲ In the CrystalDiskMark test, the read and write speeds of Q8T1 1M sequential access can break through 10,000MB/s, and the mixed test score is 7,933.19 MB/s.
▲ Q32T1 128KB sequential access also has a good score of more than 10,000MB/s, and the mixed test score is 6,725.16 MB/s.
▲ In the Q32T16 4K random access test project, the read performance reached 6,012.32MB/s, and the write performance was 4,893.64 MB/s.
For users, a solid-state hard drive with higher transmission performance can bring the greatest benefit, that is, it can shorten the opening and loading time of programs. For a more agile and fast user experience.
The author reminds again that since the SSD solid state drive used in this test is an engineering sample, and the firmware is still being adjusted, there is still room for improvement in the performance of the final version.
Considering that GIGABYTE has previously released the AORUS Gen5 10000 SSD series solid-state drives using the same controller chip, the sustained read speed can exceed 12,000MB/s, which makes people look forward to the performance of the final commercial products.
