Phison Electronics announced that its flagship SSD main control chip PS5012-E12 has been put into production, and more than 20 related SSDs are under development.
This main control is manufactured using TSMC's 28nm process, supports eight NAND flash memory channels, supports PCI-E 3.0 x4 bus, NVMe 1.3 standard, fourth-generation SmartECC LDPC error correction mechanism, AES-256/TCG Opal/TCG Pyrite security encryption and other technologies, it is compatible with future 96-layer stacked 3D TLC/QLC flash memory particles, with a maximum capacity of 8TB, and also supports Thunderbolt 3 mobile SSD. In terms of
performance, officials claim that the sustained read and write speeds can reach up to 3.45GB/s and 3.15GB/s, and the random read and write speeds are both 600,000 IOPS.
TweakTown recently obtained a reference design SSD based on E12 master control, and has the latest version 11.0 firmware. The performance and functions have been greatly improved, and before it is launched into the retail market, Phison will improve another version to focus on improving performance. The reference design tested by
is an M.2 2280 SSD, equipped with Toshiba's 64-layer stacked BiCS3 TLC flash memory, with an original capacity of 1TB and an actual usable 960GB, paired with SK Hynix DDR4 cache. The performance of
is rated at continuous reading and writing of 3.2GB/s and 3.0GB/s, which are the standards previously announced by Phison, while random reading and writing are both 600,000 IOPS.
There are six SSDs participating in this comparison, namely HP EX920/ ADATA SX8200 ( Huirong SM2262+ Micron
12KB continuous reading: E12 is a bit slow, and the best performance is reached only after the queue depth is DQ8, which is stable at around 3.5GB/s . It seems that low DQ is the focus of the next improvement.
12KB continues to be written: quite fiercely, and soon stabilizes at 3GB/s, crushing everything.
128KB was written continuously: it was leading steadily all the way, even worse than Samsung 970 PRO. TweakTown said that it is thanks to the new firmware and redundant capacity, but it is a bit too incredible. It is completely black technology. I can't help but suspect that all the data used in the test is compressible data, and E12 has turned on data compression.
4KB random read: upstream level, the new firmware also improves the performance of QD1.
4KB random write: This time it is obviously much weaker, and it is obviously not the strong point of E12.
128KB mixed continuous reading and writing (reading accounts for 70%): a complete failure, but fortunately there are not many such usage environments.
4KB mixed random read and write (reading accounted for 70%): similar to continuous reading, it is also a latecomer, but the daily use environment QD is not high, so it still needs to be optimized.
Game loading time: almost the same, but E12 can be better.
PCMark 8 storage bandwidth: close to 700MB/s, the performance is acceptable.
PCMark 8 total bandwidth: similar to SanDisk Extreme PRO, the best outside of Samsung.
SYSMark 2014 SE system response: Except for Toshiba XG5, the performance is not much different.
SYSMark 2014 SE system power consumption: E12 is another surprise, the energy efficiency is far ahead. This is also the first time that Phison master has such performance.
