群联PCIe 5.0主控性能公布：最高支持32TB、速度12GB/sPhison’s PCIe 5.0 master control performance announced: support up to 32TB, speed 12GB/s. Previously, the world’s largest SSD master chip company Phison announced the information about its first PCIe 5.0 master chip PS5026-E26. Now this chip is now available It has been officially released, with a maximum speed of 12GB/s and a maximum capacity of 32TB.
According to Phison's information, the PS5026-E26 main control supports PCIe 5.0 x4 channels, supports NVMe 2.0 standards, adopts TSMC 12nm process, FCCSP 576 package, and has a center area of 16x16mm. It integrates 2 ARM Cortex-R5 centers and 3 dedicated IP centers. , Support DDR4/LPDDR4 cache, up to 32TB capacity.
In terms of functions, PS5026-E26 has a read speed of 12GB/s, a write speed of 11GB/s, 4K random read 1.5 million IOPS, and 4K random write 2 million IOPS.
From a functional point of view, the read and write speed of the PS5026-E26 master is not very high. The PCIe 5.0 hard drives released by Samsung and Kioxia have surpassed 14GB/s. Phison’s first PCIe 5.0 master obviously needs to save Some, which can only achieve 12GB/s, may be related to the fact that the main control chip will be a 2-core R5 from the previous generation's 3-core R5.
However, the random function of this master control is very strong, up to 2 million IOPS, which is considered the top level in PCIe 5.0 at that time, doubled than PCIe 4.0.
According to Phison, the PS5026-E26 main control chip will be available in the second half of this year, and it is not known which SSD company will launch it.
此前全球第一大SSD主控芯片公司群联预告了旗下首款PCIe 5.0主控芯片PS5026-E26的信息，现在这款芯片现已正式发布，最高速度可达12GB/s，最高支撑32TB容量。
依据群联的信息，PS5026-E26主控支撑PCIe 5.0 x4通道，支撑NVMe 2.0标准，选用台积电12nm工艺，FCCSP 576封装，中心面积16x16mm，内部集成2个ARM Cortex-R5中心及3个专用IP中心，支撑DDR4/LPDDR4缓存，最高支撑32TB容量。
功能方面，PS5026-E26读取速度12GB/s，写入速度11GB/s，4K随机读取150万IOPS，4K随机写入200万IOPS。
从功能上来看，PS5026-E26主控的读写速度并不算多高，此前三星、铠侠发布的PCIe 5.0硬盘速度都冲上14GB/s了，群联首款PCIe 5.0主控显然要保存一些，只能做到12GB/s，有或许跟主控芯片从上代的3核R5将为2核R5有关。
不过这款主控的随机功能很强壮，最高可达200万IOPS，算是当时PCIe 5.0中的拔尖水平，比PCIe 4.0翻倍。
依照群联的说法，PS5026-E26主控芯片会在本年下半年面世，还不知道哪家SSD公司会首发。
